The ease with which individuals gained access to this young female, enabled them to judge of the truth or falsehood of the reports in circulation, and they disseminated their opinions far and wide, so as to attract, not only the at- tention of the curious, but of men of science. As 1 had attended Miss M'Avoy during the period when she lost her sight, three months previous to my knowledge of her possessing these powers, and, having minutely exa- mined into the truth of her statement, by making those experiments I deemed satisfactory of her claim to the pos- session of them, I felt it an incumbent duty to give all the information on the. subject which lay in my power. I was induced to do this more particularly from the repeated demands which were made by the different periodical wri- ters for information. In the Narrative I stated the circum- stances which appeared in her favour, as well as those which were against her ; and my intentions before and after the time of printing the Narrative, were repeatedly declared, a VI PREFACE. orpablishiug whatever could be advanced against her by any other person. Her opponents kept to them- selves the proofs they since have given to the public, trntil the Narrative was published, that by seeing the de- tail of experiments made to ascertain the truth, they might be enabled to garble from it, those parts which would give more weight to their assertions. The candoyr and fairness of my statement were uni- formly allowed in the first instance even by those critics who afterwards vacillated in their opinions. Having no theory to establish on her blindness being proved, and being arrived at that time of life, when new opinions or reputed facts are questioned before they are admitted to be true, I could have no motive in assert- ing Miss M'Avoy to be blind, but the conviction she was so ; and this conviction has cot been produced, in my mind, upon slight grounds, but from the result of expe-* riments made to ascertain the fact, which have been heretofore deemed sufficient to satisfy the Anatomist and Philosopher. Indeed her blindnests was not disputed until the period when it was discovered she possessed the power of distinguishing colours, &c. But when she be- gan to discover colours, by the medium of the fingers, through glass, and objects which were passing or statio- nary in the street, through the same medium, every per- son began to doubt the truth of the assertion; and I doubted, until, by the experiments I made, I found I must believe in the fact, or resist the evidence of my senses. Huitian record had given no proof of powers of this de- scription, and it was very natural for scientific men who had not seen Miss M'Avoy, to give her up as an impos- tor. In the History of Nature, however, cirenmstance.s equally extraordinary have been found to exist ; and PREFACE. Vll those facts, which a century ago would have been thought impossible, have been admitted in the present day. Sed neqae tam facUis res ulla est, quin ea primum Diflficilis magis ad credendum constet : itemque Nil adeo magnum,, nee tam mirabile quicquam Principio, quod non minuant mirarier omnes Paullatim ; — The uncertain state of Miss M * A voy's health, fora very long period to the present time, which frequently indi- cated a fatal termination, prevented me from publish- ing the continuation of her case, and for the same rea- son I did not think it necessary to enter into any de- fence against the numerous assailants of her integrity, as 1 bad only a very few proofs to advance in addition to those already stated in the Narrative, Miss M*Avoy having lost, in a great measure, for nearly the same period of time, the powers which had so much distinguished her. I had also a stronger reason for deferring the pub- lication, for, in case of her decease, her friends, in conse- quence of Miss M'Avoy's own request, would have per- mitted her body to be inspected, by which the nature of the disease might have been elucidated, and the fact of her blindness, or the contrary, been proved to the sa- tisfaction of all parties. Had such an event taken place, I should have given another proof, that in this whole affair I have acted under no concealment, but with that openness, impartiality, and wish of investigat- ing the truth, the importance of the case demanded ; for it was my declared intention to have invited, particularly, those persons to be present at this examination, who, without sufficient inquiry, had been most virulent in their assertions of imposture. However gratifying, un- der such an event taking place, the inquiry would have Viii PREFACE. been to me, and to the friends of Truth, I rejoice Miss M *A voy still lives, and although her health is in a most precarious state, I yet hope she may ultimately recover, and that the fact of her blindness may in some other way be clearly ascertained. I see no reason why acrimony of language, or a want of forbearance towards those who support the opinion of Miss M*Avoy's blindness, should have been so much excited by her opponents. They have shewn a feeling more indicative of personal pique than of justice to Miss M^Avoy, and in the violence of their op- position, resting upon a very slight evidence, they have brought themselves before the bar of the public, and have in a certain degree, influenced that public to agree with them in opinion. But the advocates of Miss M*Avoy's blindness do not rest their opinion upon slight grounds; they have examined and re-examined it, and they more firmly adhere to that conviction which was impressed upon their minds in a very early stage of the business. The public is in the end however a just judge; it acts from the evidence before it, but, as it does not aU vrays obtain that evidence in the most direct way, it must await the period when the production of facts will do away the prejudice, by which the individual, forming a part of that public, is generally too much actuated. The manner in which this opposition has been carried on, induces me to suppose the grounds upon which Miss M*Avoy's opponents rested their proofs did not convince themselves, at least had a very weak foundation, or they would not have had recourse to those means, which had the effect of suppressing inquiry, and of arresting any evidence in her favour. At the period when the public attention had been given to the report of her powers; when the evidence of her PREFACE. iX. possessiug these powers was stronger than that which could be brought against her; when her friends had declared their willingness to allow any examination, which scientific men might wish. What do I find in a periodical publication under the head of A Retrospec- tion of Medical Science, in the London Medical Repo- sitory, for December, 1817, relating to this subject, but the following paragraph : — ' In noticing the physiology ' of vision our readers may expect that we should make ' some observations on the case of Miss M'Avoy, of Li- ' verpool, which was lately brought before the public by ' the Rev. Mr. Glover, and Dr. Renwick. We have ' only to state that, on a visit which Mr. Thomson (one ' of the Editors) made to Liverpool, although he had not ' an opportunity of seeing Miss M*Avoy, yet, from the ' information which he had received from Dr. Traill, Dr. * Vose, and several other respectable persons in Liver- * pool, able to form a correct judgment on the subject, * there is not the least reason for doubting that the whole ' is a gross imposition upon public credulity. This has * been clearly pointed out also, in a pamphlet on the sub- * ject, written by Mr. Sandars of Liverpool, although the * motives that have induced the young Lady to invent, * and perform so singular a farce cannot be readily ex* * plained.' ' This paragraph is not less extraordinary for the injus- tice of the information which it contains, than for the credulity of Mr. Tiionison, to whom I cannot attach any degree of credit, as a man of research, for the purposes of his Repository. It was an easy matter to have made further inquiry before he published this libel upon Miss M'Avoy. I doubt much if he had read the Narrative or he would have seen what opportunities Dr. Traill had of judging of her case; and as Dr. Vose was scarcely X PREFACE mentioned in it, except as a visitor at Waverfree, it might be supposed he had still fewer means of obtaining infor- mation on the subject. Mr. Thomson certainly did not act with the usual prudence of an Editor, in deciding from ea; parte evidence, that imposture existed, and I have no doubt he will regret that, upon a subject of this importance, he depended upon the ipse dixit of any man, when he had the opportunity of judging for himself. Some of her opponents have propagated a report as far as their influence extended, that the illness of Miss M'Avoy was even feigned. It is unnecessary for me to refute an assertion of this kind, but it is indeed extraor- dinary, that men of the least respectability of character, dare to pass such an opinion upon the public, when they must be well aware, there is no foundation for it, and when the strongest evidence could be produced to con- tradict it. When public opinion could not be entirely preju- diced by the united efforts of a strong party, advanc- ing arguments against her possessing these powers, or in refuting the proofs in her favour, they were induc- ed to change their mode of attack, and, to effect the pur- pose of influencing this opinion, have endeavoured to turn into ridicule, not only the proofs, but the persons who witnessed them. Ridicule is a dangerous weapon in the hands of designing persons, and the fear of being the object of it, will often deter men of good sense from supporting their opinions with proper firmness. How- ever dastardly such conduct may appear to those who will dare to support what they believe to be true, against the united efforts of private pique, party preju- dice, and personal interest; yet, great allowance is to be made for those who are formed in a weaker mold, and PREFACE. Xi whose situation in life prevents them from hazarding the very means of existence, by advocating* the truth against the influence of power. This conduct of Miss M'Avoy's opponents, has however had this influence, and many individuals in Liverpool, who combine the advantages of situation, property, and of ability, have even allowed themselves to be silenced in this way, though convinced of Miss M'Avoy's blindness, and of her having possessed very extraordinary powers. " For still the world prevail'd, and its dread laugh *' Which scarce the firm philosopher can acorn." As scandal increases by propagation, so have some of Miss M'Avoy's opponents gone still farther, and charg- ed her immediate friends, her late confesssor, Mr. Tho- mas, and me, with conniving at the imposition, but I shall pass over so infamous a charge with the pity it de- serves. It could only have originated in minds which, being really depraved, have more pleasure in looking at the worst, than the best side of human nature, and who, by endeavouring to injure the characters of their neigh- bours, gratify those malignant passions which degrade themselves, but cannot hurt the other parties. The truly good mind will give no weig^ht to aspersions of this na- ture, but the bad will appreciate them as originating in the counter-part of themselves. " Qui alterum incusat probri eum ipsum so intueri oportet." The plan I pursued in the Narrative has been objected to by individuals who wished for the immediate gratification of their curiosity, because it unites too closely, the medi- cal with the experimental part of the case ; but I think this objection is made without sufficient reason, as the dis- ease Miss M'Avoy labours under, is evidently connected with a peculiar state o the nervous system, which must have given rise to thi.- f faulty of distinguishing cGlours, Pulv.

November 19th. — She was bled this morning, and the blood was cupped and slightly huffy, about six ounces were taken away. Pulse 120. November 22d. — Mr. Tudor bled her yesterday, and took about eight ounces of blood which was cupped, but not huffy. She complained of a violent pain upon the upper part of the sternum, but the bleeding relieved it. The tumour evidently increases in size. Pulse 120.

She complains of being swelled all over her ; but the legs are not so much swell- ed as before. Pulse 120. Alvus astricta et urina parca. Kepr. V. S. November 27th. — Mr. Tudor tx>ok away fully eight ounces of blood, which was cupped but not buffy She obtained considerable relief from it. The serum has been of a dark whey colour in many of the last bleedings, but the crassamentum has been firm. Pulse 120. Alvus constipata. Repr. PiL Hydr. submur. Gum jalap. November 29th. — Mr. Tudor bled Miss M^Avoy again yesterday, and took away about eight ounces of blood. She was seized with fainting, and afterwards with convulsive twitchings, and to-day she was insensible. Pulse 120 to 130 ; has taken little food for some days back. November 30th. — She was seized in the same manner n(^arly as in the last attack, but not in so violent a way. Pulse not easily to be counted, but tolerably full, and if one could judge from a few pulsations, not exceeding 130 pulsations in the minute. Mrs. Hughes observed the suspension of breathing to take place in the night for about a minute at a time. Takes no food, but sugar and water, and Mrs. Hughes thinks she is at times sensible. The eyes roll to and fro, and sometimes one eye is turned inwards and the other outwards. The laborious breathing is much less than in the last attack. Alvus astricta. Urinse semilibra per viginti qnator ultimas horas reddita fuit. 6& Dec. 3d. — Yesterday she became sensible, but could not speak. Complains of the oppression and catching in breathing. Pulse 144.

She fainted, but when I visited her she was much better, and was engaged in sewing. Pulse 120. The blood was cupped and buflFy. December 13th. — Complained of the catching and oppression in the breathing, and of the occasional con- vnlsjive motion of the diaphragm. Her legs and feet swell very much, and are painful to the touch. Pulse 120. Urina magis parca. Repr. V. S, I 66 December 16th. — Mr. Tudor got very little blood o» the 1 3th, but yesterday he obtained about seveu ounces, which was cupped and slightly buflfy. The coag-ulum firm, but the serum, in considerable quantity, was of a milky whey colour. Complains of pain in both arms, but particularly in the right, which is swelled, pellucid in appearance, and slightly inflamed, but does not pit upon pressure. Pulse 120. December 18th. — The oppression in breathing, and convulsive motion comes on more frequently, and she complains of acute pain about the region of the heart. Pulse 120. December 19th. — Mr. Tudor, yesterday, took about five ounces of blood, which contained a small proportion of crassamentum to the bulk of the serum. She was how- ever much relieved by it, and the swelling and pain in the right arm subsided very considerably. Pulse 120. December 25th. — Complains occasionally of her former symptoms. Pulse 112. Alvus obstipata. Urina parca. Rcpr. Pil. Cath. January 2nd, 1819. — The former symptoms returned with more violence; and Mr. Tudor took about six ounces of blood with very considerable relief. On the 30th ult. she was bled, and the blood was cupped but not huffy. The tumour increases in size, and she has complained for some time of a swelling externally about the loins, which I have not yet had an opportunity of seeing. Pulse 120. Takes little food. Alvus as- tringitur. Urina redditur liberiiis. January 9th. — I examined the swelling above men- 67 tioned, a few days ago, with Mr. Thomas. It was per- ceptible, but not large ; the fluctuation was evident about the middle part of the sacrum, but she could bear mode- rate pressure upon it. Mr. Braodreth accompanied me to-day, examined it particularly, and plainly felt the fluctuation. It extended to both hips. Mr. B. examined the tumour in the left side, which was fuller than I had observed it lately, but still extremely acute, and sensible to the touch. Is troubled with the catching in the breath • ing, and oppression about the region of the heart, i recommended her to be bled again if these symptoms did not abate in violence. January I7th.— Mr. Tudor bled her yesterday with considerable relief. The blood was very slightly buflfy, but not cupped, and the serum was in large proportion to the crassamentum, but it had not flowed very freely from the arm ; she takes little or no food. Appears to be very low. Pulse 100 to 108. January 22d. — The catching and oppression in the breathing are very troublesome ; has no appetite for food, takingscarcely any thing but sugar and water. Mr. Brandreth, Mr. Thomas and I examined the tumour in the left side, wljich pointed more, about two inches above the navel, and an inch and a half to the left of it. Could not bear any pressure upon it: the fluctuation was evident between the hips ; an enlargement was felt upon the sacrum, below the left lumbar vertebrae. She suff*ef ed pain from the pressure. Her cap was taken off", and in this situation the character of blindness was very remark- able. Pulse from 108 to 120. Alvus obstipata. Urina parca. Repr. Infus. Sennae, u. a. January 29th.— Pulse varying from 104 to 120, irregu- 6S lar but moderately free. Finding' her very unwell, and Mr Tliomas's arrival very uncertain, I took about six ounces of blood from the arm, which almost immediately relieved her. The pulse after the bleeding fell to 96 ; rose ag-ain to 120, and was more regular and steady in its pulsations. The blood whilst flowing was apparently very thin, and appeared as blood diluted with water ; af- ter standing for some time it was cupped but not buffy. The green pigment was observed at the bottom of the cup. Supervenit, post infusum sennae acceptum, diarrhoea. January 31st. — Mr. Thomas being unwell, Mr. Nairn visited Miss M'Avoy yesterday, and finding an exacer- bation of the oppression in the breathing, bled her to the amount of nearly ten ounces. The blood was cup- ped with the vermilion border. The serum in this blood, and that of the 29th, had a dirty yellow tinge. Pulse 120. Has taken no other food but sugar and water. Is at times unconscious of what is going forward. February 1st. — Complains of great debility. The oppression in the chest, and difficulty of breathing, are considerably relieved. Has no inclination for food. Diarrhoea tamen manet. Pulse 120. Capt. Tinct. opii. gtts. v. quarta quaque bora si urgeat diarrhoea. February 3d. — Complains more of the oppression and catching in the breathing. Her mother has observed her to dose during the night, for the last fortnight, but Miss M'Avoy does not feel herself much refreshed by this kind of sleep, and doubts if she has been asleep. Pulse 120. Diarrhoea non sistitur. Repr. Tinct. opii. u. a» February 5th. — Continues much the same. Pulse 120, 69 The legs and feet are very anasarcous. Diarrhoeam sistitit laudanum, February 8th. — Mr. Udney, a Surg-eon lately settled in town, expressed a wish to see Miss M'Avoy ; he accom- panied Mr. Nairn, and met me at two o'clock. Mr. Udney examined Miss M'Avoy's eyes, and tried those experiments, as tests of her blindness, which he thought necessary. Having mentioned an experiment I had made before by levelling a pistol suddenly at her head, without producing the least shock, without the slightest tremulous motion of the muscles of the face, and without her knowledge, apparently, that such an experiment had been made; having the pistol in my pocket, these gentlemen were induced to repeat it, and the result was similar to that of mine. Mr. Nairn scarified slightly the leg, which was the most swelled. The oppression and catching of the breathing became more violent from the fatigue of loosening her clothes, that we might examine the tumour in the side and back ; that in the side pointed much more fully than I had seen it ; and that upon the OS sacrum was sensibly felt. The pulse when Mr. Nairn came in was 108 ; upon my arrival it was 120, and imme- diately after the examination it was 168. February 10th. — The oppression and catching in the breathing are better, Mr. Tudor bled her yesterday, and found the symptoms were much increased in violence. He took about five ounces of blood, which was cupped and slightly buffy, with the bright vermilion tinge on the edge of the cupped blood. Pulse 120 and feeble. She takes scarcely any food, but sugar and water Once or twice lately, she wished for a little bacon, in which request she was indulged, and she has now and then taken milk boiled with a little flour, which generally brought on the diarrhoea again. 70 February 12th. — Is considerably relieved by the scari- fications which discharge very freely. Has taken a little food for two or three days. Pulse from 104 to 120. Alvus solvitur et urina libera redditur. February 14th. — Complains of weakness and want of appetite. The leg's discharge copiously. Pulse 108. Alvus elicitur, et urina, cum dolore, parca. February 16th. — Complains of more oppression about the chest. Pulse 120. Alvus valde liquatur. Repr. V. S. February 19th — Mr. Tudor took about five ounces of blood on the 16th, which relieved her considerably. It was cupped and slightly bufify; and the green appearance was observable at the bottom of the cup. About ten o'clock this morning, she was seized with shiverings, and complained as if cold water were trickling down her back. She seemed shrunk in her general appearance. The legs discharge very little. Pulse feeble, irregular and not to be counted. Urina modice redditur, sed cum do- lore. Iterum scarificentur crura et pedes. February 20th. — The shiverings continue ; she is very weak, and not always sensible. The pulse fuller than yesterday, but irregular in frequency and strength. It was counted at different times by me, Mr. Nairn, and Dr. Hannay, from 144 to 168. The legs were again scarified. Alvus astricta. February 22nd.— Is rather better. Pulse 120. The scarifications did not occasion much discharge, and the operation was repeated. February 24th. — Complains of more pain, particularly 71 hboul the chest, extending to the stomach. Tlie opprcs-* sion and catching in the breathing have returned with considerable violence. The legs and feet discharged veryi little, and a couple of deeper scarifications were made by Mr. Bennet, Surgeon, who accompanied me. I recommended her to send for Mr Tudor to bleed her if the discharge from the legs did not relieve the oppreg- «ion,4fec. Pulse 120. March 2nd.— Mr. Tudor bled her on the 25th, and obtained about five ounces of blood, which was slightly- cupped . The bleeding relieved her at the moment, but before he left her, the oppression returned. A very con- siderable discharge took place from the legs. She felt herself better, but yesterday the shiverings returned, and frequently came on to-day. Complains of conside- rable pain in the chest, and of oppression in her breath- ing. The pulse during my visit, varied from 160 to 180 pulsations in the minute; it was irregular in strength, but was fuller than I could have expected. Complains of great thirst. Per aliquot dies alvi dejectionem non habuit. Urina redditur modice sed tamen cum dolore. Repr. Infus. Senna, u. a. et Mist alkalin. cum succo limonum. March 6th — The discharge from the legs has been extremely copious, and her breathing is better, but the convulsive twitchings come on occasionally, and she is never free from head-ache. Pulse 108, appetite rather better. March 12th. — Continued better for a few days, but to-day there was a return of the shiverings. The tumour appeared more generally enlarged, extending almost from the navel to the ribs on the left side, and forward 7S to the spine of the ileum. Pulse 144, irregular in ful- ness and strength. The legs discharged very little. Repr. scarificationes cruris unius, vel amborum, si sit occasio. March 14th. — Complains of violent pain and throbbing in the fore and back part of the head, and of pain in tiie sockets of the eyes. The scarifications of the legs were not made; the swelling had increased ; the difficulty and oppression in the breathing are now worse. Pulse 120. The scarifications were again advised. Alvus soluta, et urina reddita modic^. March loth. — I visited Miss M'Avoy, with Dr. Meyler of Dublin, and found her labouring under considerable pain and uneasiness. The upper lip was bedewed with perspiration, an indication of serious suffering. She was partially convulsed, and her eyes rolled to and fro. In the night these symptoms are said to be more violent. — During our stay, she was occasionally sensible. In the muscles of the neck there was a considerable contractile motion. The Pulse varied from 144 to 204, was at times full, at other times receding and intermitting. The calculation was made by five seconds. The number of pulsations varied as each person felt it. The legs were scarified to-day. The tumour was evi- dent, but did not appear quite so;protrusiveas it did a few days ago. Nimisliquatur alvus. March 18th. — The convulsions continue at intervals When able to express herself, she complains of violent pain and throbbing in the back of the head ; is aiflicted 73 with twitchings, and there is occasionally a strong action in the mastoid muscles. Pulse 144. March 20th —Visited her with Capt. Farrar. She was convulsed when we entered the room, and continued so for several minutes. Pulse not easily counted. Slight convulsive twitchings, and catching in the breathing, occur frequently. Abradatur capillitium, et applicetur capiti empL Lyttse amplum. March 24th. — The convulsions ceased after profuse perspiration, but she still complains of pain and beating in the fore and back part of the head. Pulse 120. Has recovered thiB use of the right arm ; the leg of that side is still paralysed, but the swelling has nearly disappeared, the left leg is more swelled than before. Alvus et urlna naturales, March 26th. — Continues much the same, but complains more of the pain occasioned by the swelling of the left leg, and it now extends up the thigh. Pulse 120. The left leg was scarified in a few places, March 3 1st. — The left leg discharged freely, but the swelling is very little decreased. Pulse 120. Alvus soluta. April 1 1th. — She continued better for several days, and had not been troubled, except in a very slight degree, upon any sudden noise or alarm, with the convulsive twitchings or catching in the breathing. The left leg continued to discharge very freely, until within a day or two, when the scarifications were closed up. The con- vulsive twitching and catching in the breathing came oa a few times during my visit to-day. I made a few scari- K u fications in the same leg, as it appeared that this dis- charge relieved her, although the size of the left leg and thigh did not diminish much. The right leg is a good deal more swelled, but is yet paraly tixcept one, which, being made rather deep, discharges a little matter. The convulsive twitching and catch- ing in the breathing come on very seldom. The tumour under the shoulder blade has disappeared. The legs and thighs are less anasarcous. Recover- ed the use of the right leg on the 16th inst. The tumour is still excessively painful to the touch. Is engaged in making chimney ornaments. The food she has taken latterly has been bread and milk, which now agrees with her. To sugar and water she has taken a distaste, as well as to coffee. Pulse 120. Alvus solvitur «t urina redditur libere. April 25th. — Continues much the same. The tumour increases, and points more than it did : the most elevated part is about three inches and a half from the navel in a diagonal line, extending tow ards the apex of the heart. Pulse 120. May 15th. — There was a little alteration in her com- plaints, continuing upon the whole better, until a day or two ago, when the convulsive twitching and oppression in the breathing, with shooting pains through the chest, returned. She sent for Mr. Tudor who bled her this morning to the amount of nine ounces, when she fainted. The blood was hardly bufFy, but slightly cupped, th^ 76 coagulum was firm, and of a deep red colour. Pulse 108 to 120. Per aliquot dies urgebat diarrhoea, hodid cessabat. May 17th. — The bleeding relieved her, but not so much as on former occasions. I was induced to bleed her again, and obtained about six ounces, when she became faint, but she was relieved. Pulse varying from 96 to 120, before the bleeding, and after the bleeding it was 112, more steady and full than before. Alvus nunc dura. May 27th. — Mr. Tudor bled her again yesterday, to the amount of about seven ounces ; the blood was cup* ped slightly, but not huffy. The convulsive twitching was more violent as well as the oppression of the breath- ing. Her brother died in the course of last night. Pulse from 120 to 136, and variable. Mr. Peacock, of the army, accompanied me. She was afflicted still with the oppres- sion of, and catching in, breathing; her legs were rather less, swelled. Mr. P. served in Egypt, and was conversant in diseases of the eyes, and the effects resulting from them. He observed she had the characteristic marks of blindness. Alvus obstipatur. June 5th. — Mr. Thomas bled her on the 30th ult, and Mr. Tudor on the 2nd of June, to the amount of J^even ounces each time, without material relief. The blood was slightly cupped, but not buffy. Pulse 120. June 7th. — ^Continues much the same. Mr. Peacock again accompanied me. Pulse from 108 to 120. The respiration was at the rate of 1^0 in the minute, or ten in five seconds, as it could not be exactly calculated during a whole minute, when the catching took place in the breathing. 76 June iSth. — She continued much the same for several days. Complained of occasional shiverings. The catch- ins: in the breathing, and the convulsive motion of the diaphrag-m Were more troublesome, and she seemed to suffer a g-ood deal of pain. The pain in the head and in the sockets of the eyes continue. Pulse 120. It became as frequent as 144 during my visit. Mr, Davidson, Sur- geon, who was formerly a pupil of Mr. G. Bell, of Edin- burgh, accompanied me. He examined the eyes, and agreed with me in the opinion of her blindness. Mrs. Hughes being very ill, I went up stairs to visit her, and Mr. Davidson informed me he made wry faces at her but she took no notice whatever, nor did her countenance express any knowledge of what he had been doing. June 13th.. — I found her still worse to-day. I took seven ounces of blood in a very quick stream, from the right arm, when she became insensible for a few minutes, but the pulse continued to beat. She complained of being faint, but she felt herself better with respect to the other symptoms. The pulse was 120, and irregular before, but, after the bleeding, it fell to 100, and became soft and regular. The blood was not buffy, and only slightly cupped. June 14th. — The bleeding relieved her, but not so much. Pulse 120< She again takes coffee and a little cream, but in a very small quantity. Alvus obstipata fuit per aliquot dies. June 15th. — She appears very unwell, and from the feel- ing of fluctuation in the tumour, she thinks it will break. From her general appearance I should be afraid of a return of convulsion. Her pulse varies from 108 to 120. The attempt to protrude the tongue produced 77 a more violent effect than usual^ and the pain was so great that it caused her to shed tears. My friend and school-fellow, Mr. Thomas Creevey, was walking: near Mr. Hughes's house, at the moment I was entering it. I asked him if he wished to see Miss M'Avoy. Ah ! said he, were you not taken in in that business, I answered in the negative, and I said you shall form your own judgment upon the case. Mr. Creevey saw her, and I shall leave him to give his own opinion to any of his friends who have not seen her. He had no idea from the accounts he had heard she was in so distressing a state of health. June 18th. — Mr. Lampett, a medical gentleman, retired from the profession, accompanied me to-day. She con- tinued much the same as before. Takes only a very lit- tle coffee and milk. Pulse 120. Alvus obstipata. Repr. Pil. Cath. June 22nd. — Complains of pain and fulness in the right side. Pulse 108 Alvus dejicitur. Cap. Pil. Hydr. dua« quaque nocte. June 27. — Is much worse ; complains of acute pain la the left side, and also in the right hypochondrium, ex- tending to the right breast, which is increased upon rais- ing her right hand to the head. The suspension of breath- ing now and then, comes on in the day, but very often in the night. Pulse from 120 to 140; variable in strength. Alvus dejecta. June 30th. — The suspension of breathing came on three times during the latter part of my visit A feather applied to the mouth was not acted upon by the breath, and a V6 looking-glass applied to the mouth, received no stain. As it went off the convulsive motion seemed more severe. Dr. Derrick, of Philadelphia, accompanied me. Mr. Lampett arrived afterwards. They both appeared satis- fied of her blindness, and the former gentleman declared there was the most marked character of it in her appear- ance. Pulse 96 to 120. Alvus soluta. July 1st. — The suspension of breathing comes on every three or four minutes. The duration from 16 to 35 se«- conds. Mr. M^ Donald, surgeon of Liverpool, accompa- panied me. JulySrd. — Is much the same, but complains of the pain through her side and breast, being more violent. Has eaten a few new potatoes and strawberries. Pulse 120. July 9th. — Mr. G. Bell, of Edinburgh, accompanied me. The suspension of breathing occurs very frequently. A solution of Extract of Strammonium w^s applied three times to the eye-lids and round the eye, but it did not produce any effect. There was a tremulous motion in the eye-lids, occasionally, even during the suspension of breathing, but when the eye-lid was raised and allowed to fall again, it fell as if it were dead. The eyeball ap- peared fixed at other times. The left side was examined and appeared to point much more in one place than 1 had observed it to do before. During the suspension of breathing, Mr. Bell proposed to feel the side, but her mother would not consent to it; and all my persuasions could not prevail upon her to permit it to be done. — She even shed tears upon the occasion, and charged me with having done it before, when it produced convul- sions, but I told her it would most probably not give her 7i* pain, if done during the sngpension of breathing. I even pressed her more strongly upon the refusal, and told her it might create suspicion in Mr. Bell of imposition, if she did not allow it to be done ; but her answer was, the world had spoken as ill of her daughter as it was possible, and she did not regard its opinion on this point. She was satisfied of her blindness. If she died, her dajughter, as wejl as herself, wished her body to be exa- amined, and then the opinion of those who examined her might prove if she were l?lind or not, and what was the nature of the disease in the side. She declared her daughter should not be abused as when the needle was . inserted into the toe. I was obliged to be silent. Mr. Bell would of course, make his own comments upon thi« refusal. It did not appear to me that his opinion at this time was so decidedly against her as upon his former visit. Pulse from 108 to 120. August 1st. — There was little or no alteration in the symptoms until this morning. The convulsive catching of the diaphragm, the oppression in the chest, and fre^ quent suspension in the breathing, with constant and se- severe head-ache, continue in much the same manner as upon the last report. The pulse was seldom less than 108, and did scarcely ever exceed 120 pulsations in a minute, unless from any sudden noise or alarm, or from the examination of the side, which, from the fatigue and agitation it occasioned in undressing, generally increas- ed its velocity. She took very little food, and w&b obliged to be watched closely, lest it might choke her if she attempted to swallow it a moment previous to thd suspension coming on. She tried sigain a cup of coffe« and cream, twice a day, which now agreed with her, and was her chief support, but it was obliged to be given mih great caution. When she took more solid food i| m was generally thrown off the stomach, in a few days, in an undigested state. This morning", at half-past ten o'clock, a xn. she was seized with convulsions. I found her about two o'clock in this state. They continued for two or three minutes, and were alternated with the suspension of breathing. The right leg and hand were strongly contracted during the convulsion, but relaxed upon the suspension occurring. Has lost the power of speech. • August 2nd. — Mr. Bowling, Surgeon, of Bolton, ani Mr. Bedford, of Liverpool, accompanied me. She was sensible this morning, for a little while, but could not articulate. August 3rd. — Heri,cum doloremuiio, librae duse urinae limpida?, eodem tempore, redditse fuerunt. Per aliquot diesantea alvus astricta, et urina non reddita fuit. Soon after she was seized with a severe convulsion and spasm, throwing her hands about with violence, and it required all her mother's strength to hold them so as to prevent them from doing injury to herself. She after- wards became more sensible, and was evidently relieved. She was able to put her left hand to her neck, which, for a long time before she had not done, from the pain and fulness under the clavicle. > August 4th.— Prima luce urinam reddidit pure com- mixtam. She has also recovered her speech, and the contraction of the legs and arms as well as the twltch- ings, are removed. Her face is rather more emaciated. She cannot protrude the tongue without bringing on the convulsive affection, Pulse 120. 81 August 7th. — She can bear moderate pressure on the leftside, and she says she is better now than at any period for a very long time. Pulse 108. Die augusti quiuto et sexto urina pure commixta reddita fuit libere. August 13th. — Mr. Bedford accompanied me. She see^ns much better. Pulse 96. Can protrude the tongue a little beyond the teeth, but the effort produced a slight spasm. The eyes were examined, and Mr. B. agreed with me, they had a morbid appearance, and the charac- ter of blindness. Upon Miss M'-Avoy being asked if she could bear any thing to be applied to the eye-balls, she said she could bear her finger to pass ov^er them ; and once when the eyelashes were turned under the jeye-lid, they did not give her any particular pain, but what was produced from the soreness of the eye -lids. Mr. Bedford proposed to apply a blunt-pointed probe on the cornea, which was done in both eyes, and he pressed it upon each, but she expressed no pain, but what arose from the soreness of the eyelids. Alvus soluta. August 17th. — She continues better. Dr. Jardine ac- companied me. The experiment with the probe w^as again made. A slight sensation appeared when the probe was placed on the pupil, but she complained of no pain in the ball of the eye, but of much pain in the eye- lids when they were touched. Dr. Jardine drew it back- wards and forwards across each eye, and in the first trial he depressed the cornea before he was aware he had touched it. No tears w^ere discharged, nor did there appear any sign of the slightest inflamma- tion in the eyeball. The side and the breast were opened. The pointed part of the tumour had disappeared, and she could bear moderate pressure upon it, which has not l*een the case for many months. The swelling which was L 83 observable about the upper part of the breast, and under the clavicle, was so much diminished, as to enable her to cross the left arm over the breast, as 1 have before said. August 1 8th. — Mr. Davidson accompanied me to-day, sipd not having a probe we made use of the top part of the scales of a lancet; the left eyelid was more inflamed than the day before, and whether it was touched with the lancet or not I could not say, but she complained of pain and soreness in the eyelid, but not in the ball of the eye. A tear or two passed over the eyelid, but she bore the pass- ing to and fro of the top of the lancet, across the pupil, and the cornea. I passed the leaf of a Siberian crab- apple, cut to a point, over the pupil and cornea, without producing the least motion in the eye-balls. We had provided ourselves with some coloured fluids, but although she named the colour of two of them, she did not do it with that readiness which characterized her former eff"orts. She was uncovered. » August 21st. — I found her very poorly in consequence of a cold caught by sitting in the garden. She had also a slight return of the oppression and catching in the breathing, and of the convulsive motion of the diaphragm. She was advised to take a few drops of Ipecachuana wine three times a day, and the cough being harsh and dry, 1 recommended her to lose some blood. Pulse 120, and rather full. August 23rd. — Mr. Tudor, yesterday morning, took about seven ounces of blood, when the suspension of breathing came on. The blood was slightly cupped but notbulTy. She was relieved at the time of bleeding but the other symptoms returned with considerable violence ; the cough still remained dry and harsh, and caused consi- derable pain in the breast ; I took from her about eight wunees of blood in a full stream, when the breathing was suspended, and I allowed it to run into the basin for a little longer time. She was faint for some time after- wards ; the pulse varied from 120 to 132, and became more feeble. She expressed herself as being much better, although considerably exhausted. Alvus soluta et urina modice reddita. Repr. V. S. si sit occasio. August 25th. — She was much better this morning, hav- ing lost again about five ounces of blood. The cough was relieved a little, but she still complained of pain in the breast. Pulse from 108 to 120, and once it was IS2, and feeble with clammy hands. Appr. Emp. Lyttae sterno. August 26th. — She seemed very poorly to-day. Puis© varying from 144 to 152. Skin moist and clammy. Hands cold ; complains of shiverings, of a coldness down the back, and of violent pain about the loins. The pain in the head is much increased, and there is still soreness in the chest, and cough, but the blister gave her some relief and discharges freely. Alvi habuit dejectionem ; et urina libere reddidit. Humoris effusio larga e utero, colOris subfusci et sanguinei evenit hodie, instar mensium fluxus morbidarum. Post horas quinque cessabat. August 27th. — I was accompanied to-day by Mr. M'Do* nald, house-apothecary of the Edingburgh Infirmary, and we met Mr. Nairn. She was much better than yes- terday ; the cough still continues harsh, and she com- plains of the pain in the breast. Mr. M' Donald minutely examined the eyes ; he observed the irregularity of the pupil of the left eye ; and the contraction and dilatatioa in both eyesj upon the presentation of a lighted candle. 84 He applied a similar leaf to the one I used, the other day, to the pupil ot the eye, without producing any motion in the ball of the eye, or any apparent sensibility. The Pulse wa^ frequent, but tolerably firm and full. Mr. Nairn took from the arm about six ounces of blood, which, upon standing:, had a slight buff upon it, and was a good deal cupped. The suspension of breathing came on during the bleeding. The fillet was loosened, but as the pulse remained firm, the blood was allowed to flow for some time longer ; after the suspension went off, she re- mained incapable of exertion. The arm was tied up. The pulse occasionally faltered; her hands were cold and clammy ; drops of perspiration stood upon the upper lip ; and she remained in that state, of half- syncope, which I have observed before After walkinji: in the garden we returned, and she still lay in this state with her head upon the pillow, although she faintly an- swered a question or two I put to her. August 29th. — She is better, but the cough is very trou- blesome. Alvus miniis liquatur. Urina parca redditur. Jx. Muc. G. acaciae, 5 vii, Syr. Tolutan. 5 ss. Tinct. opii. gtts. Ixxx. Vin.

Complained before of the effect of sounds, but the mixture seemed to produce the confusion. Had taken paregoric elixir of the former dispensatories,which agreed better with her she thought than the sudorific anodyne mixture. Diarrhoea per aliquot dies urgebat valde. 85 September 2nd. — The cough is not much relieved. Pulse 144 to 160. Appl. Emp. Lyttse. sterno. September 4th. — Continues much the same, but the cough is rather better. The blister was not applied. The catching in the breathing, and the convulsive motion of the diaphrag-m came on occasionally. Pulse 156. Tamen urget diarrhoea tenesmo concomitata. Repr. Pil. Hydr. submur. cum jalap, u. a. September 6th. — Found her rather better, but the cough is still troublesome. Pulse from 120 to 156. The skin moist, clammy, and cold She has left oflF both the opiate misture, and the paregoric, as they made her very uncomfortable for some time after taking them. Has not taken the pills. Diarrhoea cum tenesmo manet, Applicetur sterno Emplastrum opiatum, September 14th. — Is affected with catching and oppres- sion in the breathing, and convulsive motion of the diaphragm. The cough still continues with a considerable degree of harshness. Pulse 144. I bled her to the amount of six ounces, with considerable relief; but she was insensible a short time after the bleeding, and lay in a quiescent state for some time after I left her. September 16th. — In examining the blood, the green pigment was again observable in the first cup, but not in the second. The blood was cupped, and slightly buflfy in the first, and cupped only in the second cup. Pulse 144. Repr. V. S. September 20th. — The blood taken on the 1 6th, was slightly cupped ; the serum of a turbid whey colour ; cough troublesome and harsh ; pulse varying from 120 to 144. Alvus nim\s libera^ 86 September 23rd.— The cough and catching in the breathing were mare troublesome, with a lancinating pain in the right side. Mr. Tudor took about six ounces qf blood from the arm yesterday, which relieved her very much. She complained before this of confusion in the head, and she could not recollect what had passed. Any sudden n^oise affected her. She could not sew or net for a considerable time together. Alvus minus^ libera. Pulse 144. October 8th. — Since the last report she has been much better. The catching in the breathing seldom comes on except she attempts to protrude the tongue. Mr. John Gladstone, Ca^t. Owen, of the navy, and Dr. Nimmo, of Glasgow, met me at Mrs. Hughes's. Dr. Nimmo, sta.ted her pulse to beat at th,e rate of 136 pulsations in the minute. October 26th. — Miss M'Avoy, within this day or twty, baa felt herself much worse. The tumour appears to increase in size, and the pain, ou pressure, is more con- siderable. Pulse about 120, moderately full. The catch- ing in the breathing comes on now and then, and she appears depressed in spirits. The pain in the head and in the sockets of the eyes is very considerable. She has complained for a long time, of a numbness on the lower part of the temporal bone, and near the lower or- bit of the eye Dr. Holmes, of Canada, who lately gra- duated in Edinburgh, accompanied me in my vL^it. November 9th. — She says that her teeth are decaying and pieces come away without any apparent cause. Within these few days she has complained more of the catching in the breathing, and the convulsive Motion of the diaphragm, with g;eneral lowness of spirits and m want of exertion. She has little inclination to employ herself in sewing or making ornaments. Pulse 120, Diei quinti novembris vespere superveniebant menses coloris subfusci ; mane sequente disparuebant. Alvus libere, urina modice redditur. November 22, — Complains of pain all over her, of more violent pain in the back and forepart of the head, and in the sockets of the eyes. The tumour in tlie side increases, and that in the region of the os sacrum con- tinues to fluctuate. Shiverings occasionally come on. Pulse 108. Alvus magis aslricta. November 30th. — Is very unwell. Has been afflicted for several days with cramp at the stomach, which bends her double, alternating with increase of pain across the coronal suture, and attended with numbness of the right arm. Cold perspirations frequently come on. Pulse va- rying from 132 to 168. Alvus constipata. Sorbuit hydr. submur. c. jalap, portionem usitatam duplam vel triplam, non alvum solutam sed nauseam et vomitum, inducentis ; vice cujus substituit mater sua infus. sennae more solito. December 4th. — Dr. Meyler, and Mr. M'Donald, assistant surgeon of the Dispensary, accompanied me in my visit to Miss M'Avoy. We found her very poorly. The tumour was examined in the side. It was perceptibly elevated, and so acutely sensible to the touch, that the falling of the clothes upon it made her shrink. She at- tempted to protrude the tongue, and the catching in the breathing and convulsive motion of the diaphragm came on but she protruded it fairly over the teeth. The Pulse varied from 132 to 144, during our visit. The spasms of the stomach continue, but are more prevalent in the night-time. Warm water or weak tea affords her 88 relief. The heat of .the mouth by the thermometer was 110, in the hands 98, and in the room 75 degrees. December 10th. — Is much the same. Pulse from 120 to IS2, Alvus modic^ levatur. December 13th. — Complains of the catching in the breathing, of springing or pricking pains through the part where the issue had been made. The cramp at the stomach is more violent, and continues for a longer time. The discharge from the left leg, where it was scarified, continues. Pulse from 132 to 144. Alvus obstipata. jRepr. Pil. Hyd.

December 21st. — The same gentleman again accom- panied me. She still continued very ill. The bleeding was repeated, and we left her under symptoms of very considerable debility. Pulse from 120 to 144. December 22nd. — The last bleeding very*much reliev- ed her. The pulse was moderately firm, and vai^jed from 120 to 132.

The suspension of breathing came on very frequently, and continued from 30 to 40 seconds each time. The pulse fell to 144. The f>ppression and catching in the breathing were very trou- M 90 blesome before the bleeding, but appeared considerably relieved after it had taken place. December 24th. — Mr. Thomas's assistant, Mr. Tudor, bled Miss M'Avoy this morning, and she was again re- lieved by the bleeding ; but the oppression and catching in the breathing continue troublesome. The blood was^ cupped, but not huffy. The suspension of breath- ing came on, and he did not obtain more than five ounces. The pulse was 144, but after the bleeding it fell to 108. Two hours after the pulse varied from 120 to 132. Alvusobstipata. Stillatim mingit. December 25th.— Is extremely low, but the oppression and catching in the breathing are better. She feels inca- pable of any exertion. Complains of a whirling sensa- tion in the tiead, which takes away for the time all recollection ; gets no sleep at night that she is aware of. The suspension of breathing comes on occasionally in the day, bnt more frequently in the night. Takes no food but a little coffee and cream. The pulse 120, soft and easily compressible. Alvusconstipatur. Urinagutta- tim elicltur calida. Repr. Pil. Cathartic, u. a; January 7th, 1820. — Since the last report she has been very poorly ; has taken more food, but it was rejected \vith considerable violence ; and what had been taken some days before, was thrown up in an undigested state. Is more troubled with the catching and oppression in the breathing. Is extremely uneasy at night, with horrid isensations, as if she were in the midst of wild beasts, or falling down precipices. Complains much tff the pain in'the head, acfoss the temples, at the back of the head, and in th« soeketi of th© eyes;. Pulse 144, soft anil 91 compressible. Alvus interdum nimis libera, et alternis vioibus ssppe obstipata fait. Urina Uberius redditur. January 12th. — Complains of a pain in her side, and is troubled with a dry, hollow cough. Mr. Tudor took eight ounces of blood from the arm this morning. At two p. m. she was better, but still suffered pain in mak- ing a fall inspiration. Pulse 144. Alvus modic^ solvi- tur. Uri'na cum dolore, sed libera, redditur. Repr. V, S. et detr. sang, quant; idonea. January 13th. — Ten ounces of blood were taken away yesterday afternoon, which was cupped and buffy ; the «erum of a muddy whey colour. The suspension of breathing came on, but Mr. Tudor still allowed the blood to How until she fainted. For a few hours she was relieved, but to day is not materially better. * Pulse 136. Alvus dejieitur. Repr. V. S. January 14th. — Six ounces of blood were only obtained, which produced no material alteration, yet she was on the point of fainting. The blood was cupped and the serum muddy. Pulse 144, sharp and full. , Repr. V. S. et detr. sang. 5 viii. ad 5 ^di. Jan. 15th — Six evinces of blood were taken away. It was cupped and bulfy in each cup. When I visited her, she was extremely ill, and her voice could only be heard as the faintest whisper. Found no relief from this bleed- ing, and appeared much exhausted. Pulse 160. I wished her to apply a blister to the side, but she objected to it. as she could not bear the least pressure near the tumour. It was applied to the breast. She objected alsa to leeches, lest they should again bring on the convulsions or faints' 92 ing. Mrs. Hughes observed «he was so ill at times in the night, with the acute pain produced by the twisting about the region of the heart, that she thought her daughter could not survive the night. Her own feelings have been so oppressive as to induce her to believe she cannot for any long period bear up against them, and she is very much dispirited. Jan. 16th. — Does not think herself better; but it appears to nie sh6 is not so ill as yesterday. The catch- ing in the breathing is certainly not so frequent ; and the violence of the pain about the region of the heart is rather diminished, The blister rose a little. Pulse 144. Softer and compressible. Alvus comprimitur. January 18th. — There was little alteration in her com- plaints, until the last night, when the pain about the region of the heart, the cough and diificult breathing increased so much as to make it necessary to bleed her. She lost fourteen ounces of blood. The suspension of breathing came on four times during the bleeding ; and when I visited her about an hour after, it occurred every three or four minutes. The blood was in the slightest degree cupped, and without buff. T}ie more violent symptoms of cough were relieved. The pulse when I first felt it was 144, but it very soon after fell to 120 pul- sations in the minute. Alvus obstipatur. Repr. infus. senutT, u. av January 20th. — Ts much better, but complains still of the pain and twisting about the region of the heart. She speaks of a chilly, creeping sensation over the heart, and of a symptom, as if a cold ring were placed upon the point of it, and preceding a disposition to fainting. Pulse 132. Infusum sen: sursumet deprsum, opusperegit. 93 January 22nd. — The oppressive symptoms have recur- red. The pulse irregular and receding. When it can be counted it varies from 142 to 144. Cap. vin. Ipec. gtts, xx. ter de die ex aquse pauxillo. January 23rd. — The suspension of breathing came on frequently in the day-time, and very often in the night. Pulse 176, irregular in fulness and in strength. The vomiting occasioned by the infusion of senna agitated her very much, swelled and distorted the muscles of the face and neck, so as to cause an increase of pain in the h4ad to so great a degree that she was afraid to take the Ipecachuana wine, lest it might bring on the' sickness again. Takes very little food of any kind, but has a fancy for that which is tasty. Attempted to take a mouthful of beef or of mutton occasionally, which pro- duced nausea and sometimes vomiting ; yet she took with impunity a very small portion of roasted pork, and a teaspoonful or two of potatoes mashed up with the gravy, whilst the gravy of either of the other meats dis- agreed with her stomach. January 24th. — Is still worse. The pulse 160. Mr. Tudor took twelve ounces of blood away, which was cupped but not huffy. Kepr. V. S. si sit occasio. January 25th. — Mr. Tudor attempted to bleed Miss M*x\voy this morning, but did not succeed. She had been bled so often that the cicatrices were numerous and hard, so that although the blood spurted out as soon as the lancet entered, yet no more blood followed, and he was obliged to give it up. At three o'clock, p. m. I found her so very ill that I Was induced to tie up the arm and make another attempt. The only point of the 94 Medio. Basilic vein, that I could feel distiactly, was above the cicatrices. 1 made a large incision fairly into the vein, but only a spurt of blood followed, as if the vein below were closed up by the thickening of its coats. — I succeeded at last by making a large opening into the vein of the left arm, and the blood rushed out with vio- lence into my breast and face. Almost immediately the hreathing, as I thought, became suspended, and I placed my thumb upon the Q,ri£ice. Upon pressing the wrist I felt no pulsation. Upon her recovery, which took place in about a quarter of a minute, I took my thumb from the orifice, and it rushed out with great violence, when she again fainted. After this recovery, a third attempt was made, s^nd syncope foHowed. Upon her recovery the carotid arteries beat with unusual violence ; the lips became pallid ; under the eyes and round the mouth, the skin appeared of a pale blue colour; the handg were oold and clammy, so that I felt myself bound to desist from allowing the blood to How again. The pulse which hftd been so frequent as 160 pulsations in the minute, fell to 132 The violent pulsation of the carotid arteri^Si abated ; yet, although she appeared languid, it was evi- dent to me, as well as to herself, that the small quantity of blood, which hardly exceeded two ounces, by having been taken away so suddenly, had produced the full effect of a larger bleeding. January 26th, — Continues very feeble, but the more violent symptoms are rather better. The pulse varies from 144 to 160 pulsations in the minute, and is irregular in fulness. Alvus astricta fuit per a|iquot dies. Urina libere redditur. January 27th. — Appears upon the whole better. Pulse from 144 to 180, soft and easily compressible. The legs u are more anasarcous, and the general appearance of the face and body is leucophlegraatic, Alvus nimls deji- eitiir. January 30th. — Is very low, but in other respects bet- ter. Complains of pain and lightness in the head, of sick- ness at the stomach, but has not rejected the cup of cof- fee and cream she took at breakfast. Pulse 144 to 160. Diarrhoea tamen urget. February 7th. — Continues much the same. Puis© 160, February 9th . — Is rather worse. The swelling in both legs, particularly the right, disappeared rather suddenly, on Monday, and the abdomen is more tumid. Pulse from 120 to 144, and feeble. Takes very little food. Cutis mollis. Diarrhoea tamen manet. February 12th. — Has taken cold. The catching in the breathing, the twisting about the region of the heart, and the cough are increased. Her mother attributes the cold Miss M'Avoy has caught, to her having fainted, and hav- ing been exposed to the cold air, during the operation of changing her linen. It seems she is in the habit of doing this at night, and it is a very tedious business un- der the circumstances in which she is placed. The pulse is fuller, and more firm, from 120 to 144. Diarrhoea urget. ficpr. V. S. et detr. sang, quant, idonea* February 13th. — Twelve ounces were taken away, the blood was cupped and buffy, exhibiting the green pig- ment at the bottom of each cup. The symptoms wevid relieved after the bleeding, but returned tg-day with con- 96 siderable violence. Complains of tightness, and of a sense of weight across the chest. Pulse tolerably full, varying from 120 to 144 pulsations in a minute. Repr. V. S. u. ar February 14th. — Fully fourteen ounces of blood were obtained, which was slightly buffy and cupped. The se- rum was in a much greater proportion to the crassamen- tura, and was of a muddy whey-like appearance. She was relieved by the bleeding, but the violent symptoms again came on, and the cough was very severe and dis- tressing. Pulse 144* Mr. Parr, a respectable practitio- ner in Liverpool accompanied me in my visit. February 15th. — Is rather better, but complains of thirst and nausea, for which she has taken a pretty strong lemonade, with temporary benefit. Complains of consi- derable pain under the left clavicle, and of a sharp pain strikiug through the tumour in the left side. Repr. V. S. u. a. February 16th. — I do not think her worse, but she seems to yield more to her sufferings than usual. Mr. Tudor attempted to bleed her this morning, but did not succeed in obtaining any blood of moment. Mr. Thomas, who accompanied me, also opened two veins without effect. We observed her skin to be clammy and her hands cold. He informs me when that was the case, during the former attack, he seldom got any sufficient quantity of blood ; and he was not singular in this re- spect, as other gentlemen, who attempted to bleed her, sometimes were foiled in a similar manner. Pulse from 144 to 168, irregular and slightly intermitting. Diarr- hoea tamen urget. 91 February 17th. — Continues very low. Cough less harsh, and the other symptoms appear more moderate. Pulse 144, soft and compressible. Alvus non tam^a li- here solvitur. February 19th. — Is rather better. Pulse 120. February 20th.— Continues better, but the suspension of breathing comes on occasionally during the night. Pulse 136, soft and compressible. February 21st. — Is still better. Was engaged in mak- ing a purse, which she had not been able to do for a con- siderable time. Pulse 120. Alvus astricta. February 23d. — Goes on improving. PUlse 120. Mr. Bradley, Surgeon of this town, having expressed a wish to see Miss M'Avoy, accompanied me to-day. Mr. Brad- ley was a pupil of the Manchester InGrmary, and had the opportunity of seeing the practice of the late Mr. Gibson, in diseases of the eyes, and also of Mr. Simmons, a judicious and experienced Surgeon of that town. He expressed himself as having no doubt of her blindness. February 25th. — Is miich the sam6. Dr. Carson ac- companied me in my visit. Pulse 144. Alvus tamea astricta. February 29th. — Is not so Well. Pulse 144. Alvus fusa. March 3d. — Continues much the same, but is only able to net or sew for a short time together. March 14th,— Since the last report she has been much N 9S better , but a week ago was seized with more violent pain at the back and in the front of the head, and through the sockets of the eyes, with a throbbing sensation. The anasarcous swelling of the legs in a great measure has sub- sided, but the left appears to contain a quantity of fluid, which moves from side to side, when it is pressed upon. The back part of the leg has a deep indentation and a blackish slough appears on the surfac^e. She is not aware of having pressed the leg against any hard substance. Mrs. Hughes applied poultices of bread and milk to the part. Pulse 120. Alvus nimis solvitur. March 18th.— Is rather better. The size of the left leg is diminished and there is a slight discharge of fluid from it. The blackness has disappeared. Pulse 120, soft and compressible. March 3 1st. — The poultice of bread and milk has been changed for one cornposed of flour, yolk of ef^g^ and of honey, which occasioned a freer discharge. Complain* of a pain and weakness in the back, and of great soreness through the whole length of the left thigh bone. Ap- pears beltei* since this discharge has been more free ; and has made two or three purses within the last ten days. Hands cold afid clammy. t*ulse 120. Alvus soivitur et liber^ redditur urina. March 29th. — Is afi*ected with slight convulsive mo- tions in the chest aiid diaphragm, with occasional cotl^h. The left leg discharges through a spot of the size of a crown-piece, at the back of the leg, which resembles the icthyosis simpSdx. Pulse 120 to 144. Alvus liber^ solvitur. Urina modicd redditur, sed cutti dolore. April 2d. — Is somewhat better. Puis© lOS. 99 April 6th. — Complains of faintishness, and general weakness. In other respects is much the same. Pulse 140. April 9th. — The left leg is less in size ; and the dis- charge continues. Some days ago, I requested Mrs. Hughes to apply a bread and milk poultice instead of the honey, flour, and yolk of egg, which, from its colour, did not allow me to see the nature of the fluid discharged from the leg. The discharge was not so great, Mrs. Hughes observed, as when the latter poultice was applied, but there was a sufficient quantity of fluid upon the sur- face of the bread and milk poultice, to give me an idea of its nature. It appeared of the consistence and colour of arrow root gruel, to which a very small quantity of milk or cream had been added. Pulse 112. April 29th. — Has complained for some days past of shooting pains through the chest, with very slight catch- ing in the breathing. Pulse from 116 to 120, moderate in fulness. Alvus tamen liquatur. May 2d. — Complains of throbbing, which had aff*ected her for some time past, in the right side. The acute pain in the leftside continues.^ Pule 120. Alvus fusa com- pescitur. May 11th. — Continues much the same. Dr. Meyler accompanied me. We examined the abdomen and the back. The fluctuation of some fluid was very percep- tible in the lower part of the back, as before described, and an enlargement was observed in both sides. Could • Mr. Bagnold called upon me yesterday, to request permission for his rela- tive Captain Bagnold of the Marines, to see Miss M'Ayoy, and they both met me at Mr. Hughes's house to-as regular but feeble ; when she breath- ed I did not observe so much of the catching, and her respiration was much less interrupted than before. I left her insensible. j July 17th. — Continues very low. Pulse varying from 120 to 144. July 18th. — Is worse. Pulse 144, and more full than yesterday. Mr. Bradley who accompanied me opened a vein, and we obtained about fourteen ounces of blood by a full stream. Insensibility came on, and occasional sus- pension of breathing, and we left her in that state, which continued for an hour and a half. July 19th. — Is very low. The right leg; is more swell- ed , but the stitch in the side and the catching in the breath- ing are less violent. Pulse varying from 120 to 132. Has taken little or no food but sugar and water, and a tea spoonful or two of weak broth, which produced diarrhoea. The thermometer was 92 in the room, 96 in the hands, and 106 in the mouth: there was a fire in the room. July 20th,^— Is again worse. The pulse 144, moderately full. The countenance leucophlegmatie, pale, and of a blue appearance. The oppression in the breathing was so great that I bled her to the amount of eight ounces, through a large orifice. She became insensible, withosn casional suspension of breathing. 100 July 21st. — Found her very low, and scarcely able tcr speak, but the other symptoms appeared less violent. The blood taken away yesterday was cupped and buffy, par- ticularly in the first cup. The upper part of the crassa- mentum, and for half an inch down, it was of a vermi- lion colour, but the lower part was of a deep red. It was so solid that I held it up on the point of a knife : the green pigment was observable in the first c ip, and more slightly so, in the second. The pulse 120, moderate in fulness, and easily compressible. The strawberries and the broth disagree with her stomach. Diarrhoea tamen %rget. July 22d, — I found her very low, and desponding ; in a great measure doubting the possibility of her recovery ; but my hope of it taking place for a short time, is not al- together given up. Her pulse is moderate in frequency and fulness, rather low, aud 120 in its pulsations. Urget valde diarrhoea, July 23d. — Is very low, and occasionally affected with twitchings in the cheeks and in the angles of the mouth. Complains of frequent numbness in the arms and should ders, and sometimes of pain in the cheeks After the pain has gone off she feels a numbness in the cheeks. The abdo- men feels to herself more enlarged,but the anasarcous swel^ ling in the legs is not diminished. Complains of much pjvin in the head and in the sockets of the eyes. Cannot support her head in an upright posture, but is obliged to lean it upon the pillow. Pulse 132, soft and compressible. Al- vus nimis liquatur. Nausea supervenit, vomitu conco- raitata subindd. Capt. bis vel ter de die spiritus arden- tis ordinarii cochleare minimum ex aquae et sacchari pauxillo. 101 '^^ July 24th.— She was enabled to keep down half a tea cupful of thin broth three times a day, by taking the weakly diluted spirit a few minutes before; but, if it happened that the broth were not given almost immedi- ately after this small quantity of spirit, it produced a burning sensation in the stomach. Complains very much of pain and weakness ; but she is not worse than yester- day. Pulse 120, soft and compressible. July 26th.~-Is rather better. Pulse 120. July 26th.— Is very ill to-day. Her countenance hai^ a death-like appearance, her lips pallid, but the eyes, when opened, are particularly brilliant, and the pupils considerably dilated. Complains of more violent pain in the head, and in the sockets of the eyes. The pain in the back part of the head is so acute, she cannot bear the least pressure upon it without much suffering, and she says the same sensibility to pain extends along the spine to the os sacrum. Has also a throbbing sensation extending from the pit of the stomach to the back be- tween the shoulder blades, somewhat similar to the flut- tering of a bird within her. Pulse 120, soft, regular, but more feeble. Nausea frequenter, usque ad vomitum, supervenit. Diarhoea tamen urget. Urinaparca. I gave her twenty drops of vin. ipechuan. which made her very faint and sick ; but it operated slightly, and a little bile was thrown up. July 27th. — Continues much the same. The accidental clanking of the fire irons produced insensibility. The anasarcous swelling of the lower extremities is increased, and extends up the thighs. The hands and arms are also considerably affected with it, and pit on pressure. Pulse 120. Diarrhaa manet sed dejectiones minimae cum 102 tenesmo sappe redduntur. Capt. vespere infus. sennac cyathum. July 28th. — Mr. Nairn, who accompanied me yester- day, made several scarifications in the left leg ; but they hardly discharged any serous fluid. Pulse 120. Infa- «um sennse in ventriculum acceptum statim evomuit. July 29th. — Continues much the same. Dr.JHannay accompanied me. I passed the end of a bodkin along the cornea and over the pupil, so as evidently to depress it without a tear escaping, or an expression of pain. The left leg was again scarified. Pulse 120. ' ' ■» '' '-. •^(ily 80th — Is rather better than yesterday ; but com- plains of sickness. I scarified the right leg in several places to-day. Pulse 120. Capt. mist. Alkal. c. sue. iimoQ. more golito siurgeat nausea. Hora somni Rep. Pil. Cathart. u. a. July 31st. — The saline medicine relieved the sickness for a considerable time. The pills were not taken. Pulse 120. E crure dextro sc&rificato detrahitur libere humor serosus. Alvi dejectiones minuuntur. Capt. vini Lusitanici meri aqua commixti pauxillum subinde. August 1st. — Is rather better. Port wine formerly did not agree with her ; but that which was given to her yesterday, being very old, produced no unpleasant sen- sation upon the stomach, and revived her very much. She got a little sleep after taking it. Was requested to take it mixed with arrow- root gruel, in small quantities. Pulse 120, regular and moderately compressible. Urina parc^ cum dolore redditur. Diarrhoea cessavit. 103 August 2d,— I found her very ill, and her* countenance was still more changed for the worse, than I had ever seen it. The swelling- of the face and neck certainly dis- appeared, but that of the extremities was not diminished. Complained of oppression all over her. Had considera- ble catching in the breathing, and pain about the region of the heart. Had taken a savoy buiscuit, which ap- peared to lie heavy upon her stomach. Pulse 120. Alvus non solvitur. Vexat aegre prolapsus ani vei haemorrhois. Capt. viu. Ipec. gttg. x. quaque hor« parte quarta donee vomitum excitent; August 3d. — The Ipecacuhana Wine was not given to her, as she had thrown up the contents of the stomach. Takes no food, but the wine diluted with water. Pulse 120. Alvus astringitur. August 4. — Is not materially worse than yesterday, but the Pulse vacillates mor© than it has done latterly. Mr. Thomas felt the left arm and 1 the right at the same moment. He stated the pulse at 130 pulsations in the minuie. I stated it at 96. We were both right, and it varied afterwards from this lower point to 132. It fal- tered more than usual, and once or twice Mr. Thomas thought he felt little or no pulsation in the wrist. Yesterday, after she had received the last rites of her church, her breathing became interrupted, and she suf- fered under a temporary convulsion. A similar effect was produced in the night, and this morning ; she called the sensation a death fit. Her general appearance in- dicates a speedy termination to her sufferings, but there is that sort of tenacity of life about her, that although I hope little, I do not despair of a temporary recovery. The wind cherij and 100 1 totally forgot to send one to Drs. Jardine, Hannay, and several others who were interested in the case. Owing to the time of the day, the other gentlemen I presume, were not able to attend, but their absence was rendered of less importance than it otherwise would have been, by the at- tendance of other medical gentlemen of the town. The situation of Miss M*Avoy, particularly on the 8th inst. induced Mr. Harrison above mentioned, to await the period of her dissolution, and I was happy to avail myself of his experience and ability in dissection, to investigate the cause of her death, and by this means, if it were possible, to account for many of the extraordinary symp- toms which appeared to harrass her so much. I had two other reasons for preferring Mr. Harrison to any of our own surgeons, because the one party might be guid- ed too much by personal regard to me, and by the con- viction of their own mind of the truth of the statements I had made in the Narrative, and of their co-incidence with their own observations. And secondly, because the prejudice which had been excited by the opponents of Miss M*Avoy, had had material influence in making ma- ny of my brethren so completely adverse to the opinions I had formed, that I should not have been justified by the immediate friends of Miss M'Avoy, nor to those ad- vocates who have expressed themselves in her favour, if I had left the examination to them. From these considerations, I think, I shall be justified in having requested Mr. Harrison to use the knife, in pre- ference to any of our own surgeons, who could hardly under the circumstances of the case, be considered free from prejudice on the one side or on the other. C^wn*ul #Jj^frXJaptJijiw0 UPON ^jmn ®^^iB mm mum m''AW(^ii'^ I HAVE now given the particulars of the case of Miss M*Avoy, from the period of the publication of the Nar- rative, to the present time, and if any other evidence were necessary for the confirmation of the statement therein it might be easily obtained from the testimony of nume- rous individuals who have visited her separately and with me. The circumstance which has given her opponents the fairest opportunity of railing at Miss M'Avoy and her adherents, arose from misconception in the first place, respecting the influence of her breath, and the mode in which she supposed it to act in her distinction of colour, &c. Miss M'Avoy found that when her breath was im- peded by any substance placed before her mouth, she could rarely distinguish a colour, or read a letter ; and she naturally enough supposed that freedom of breathing o 106 was necessary to, and had some connection with, the power. Her opinion was taken up without due consi- deration, and her opponents seized the advantage, although aware it was founded upon an erroneous basis^ and could not be supported. A moment's reflection should have prevented the per- severance of herself and many of her friends in such an opinion, for if the breath were necessary to the elucida- tion of the colour, how could it act when she told colours behind her, or read under the bed-clothes ? During" the very short interval of unconsciousness that any obstruction was placed near her mouth, I have seen her distinguish colours, the next moment she has lost the power, and has recovered it again upon the obstruction being removed ; circumstances likely to excite a suspi- cion that the failure of the power originated in the inter- ception of the rays of light. If the obstructing? medium were placed at a greater distance, she would name colours, read, &c. for a longer period, until she felt the effect of this obstruction, and then she would often lose the power ; but sometimes she continued to tell colours, although a sheet of paper, a hat or any other substance were placed between the object and her breath. If her mind were occupied by answering questions or hearing any observation which entertained her, or if she were subjected to excess of pain from any accidental cause, the obstruction was not noticed so soon. The effect of any interposed medium was nearly the same whether the eyes were covered or uncovered. A similar result occurred, if a plate of glass were placed between the object and her mouth, through "which she might have seen, if the opinion of her oppo- nents were correct, and the colour were distinguished by the assistance of the eyes, During the more violent attacks of catching in the breathing, and of the convulsive motion of the dia- phragm, the hand, placed near the mouth, and kept there for a few seconds, produced a sensation nearly allied to syncope, and more than once convulsion ensued. Even now when these symptoms are considerably reliev- ed, she cannot bear any obstruction of this kind for more than a few seconds, without attempting to remove it. The powers attributed to Miss M*Avoy were certainly of so extraordinary a nature as to excite a doubt of their truth in the mind of the least sceptical person who has not witnessed them ; but it has been my uniform wish they should be minutely examined, and their accuracy explored by individuals capable of judging, and every facility has been afforded by the friends of Miss M'Avoy, and by herself for this purpose. It is however impossible to satisfy the minds of persons who are determined not to be convinced, and who will not take the trouble of visiting her, and of examining into the nature of her case, Nor shall I make any further effort to produce that conviction in their minds ; but to those who have studied the ample page of nature, in a liberal and enlightened manner, and to the public in general, T think I shall be able to assign such reasons as will satisfy them, not only of her having possessed the powers stated in the narrative, but of her blindness, The failure which so frequently occurred had more or less effect in agitating her, particularly if it happened when visitors were present. This agitation almost uniformly 108 increased the tendency to failure, and she could not name a colour, read a letter, or ev^en sew for hours, for days, and sometimes for weeks. This circumstance has been strongly urged as a material point against her, but I would rather adduce it as a proof in her favour, for if Miss M'Avoy's powers depended solely upon the faculty of vision, I see no reason why she might not have nam- ed a colour, read a few words, or distinguished a seal, when placed within the line of vision, yet under these circumslances she often failed, whether covered or un- covered, whether in a room crowded with company, or quietly seated by a single friend. This temporary failure of her powers has been attributed to cunning, to the object being within the line of vision, and, by not a small number, to her state of health which made her more easily susceptible of external impressions. Upon the first view of the subject, it would not appear difficult to ascertain whether Miss M'Avoy were blind or she could see, and I still think it is not so impossible of proof as her opponents wish to insinuate. Miss M'Avoy has cer- tainly given proofs of her powers before numerous and highly respectable witnesses, and in situations, where, if she had the most perfect vision, it could not have assisted her, either in the distinction of colours, in reading, or in naming the time of the day. When I recapitulate some of these proofs which have have been stated in the narrative, and a few others-which have since occurred, the public will probably agree with me, I have not advanced auy but what I can fairly and honestly substan- tiate. When duly considered, this occasional loss of power will be found to depend upon causes which owe their origin to the very peculiar state of the nervous sys- tem, in a habit materially diseased. This nervous irrita- bility was generally increased, when the atmosphere was loaded with electric fluid, and she then very rarely gave 109 any proof of her powers, but appeared agitated and uneasy. Fine weather and a clear sky exhilarated, but moist and dull weather depressed her spirits.* • From this peculiar state of her feelings, she would often foretel the approach of a thunder-storm, and she once felt a sensation she could not account for, previous to hearing the report of a cannon from a vessel of war, lying about four miles from the place where Miss M'Avoy resides. Could this sensitiveness have been produced from the cfTects of vibration acting upon a highly irritable fibre ? I have known instances of other persons affected in this way, previous to the report of cannon. It is said Sir Edward Pellew saved himself from destruction by some consciousness of this kind, when the Amphion blew up. There is a woman residing in Liverpool, who is deaf and dumb ; yet she knew when the guns at the fort were fired, by some peculiar effect it had upon the nervous fibre ; and a similar effect was pro- duced by the crying of her infant, which was up stairs, at the time the mother was speaking to a person in the room below. Mr. Thomas attended this patient, in her confinenaent. Mr. Nairn mentions the case of a man who gained his livelihood by shooting wild fowl in Belfast Lough. He was so nearly blind, he could scarcely see any object at the shortest distance ; but his hearing was peculiarly acute. He was accustomed to get into his boat, and float down the Lough to the place which the birds frequented. By their cry, and the flapping of the wings, he knew when to place his gun at a proper distance, upon a resting-place in the boat, and he fired as his ear intimated to him the situation of the birds. Other individuals, it is said, followed a similar employment, but not one of them with so much success as this poor man. A still more extraordinary case has been mentioned to me, by the Rev. J. Hornby, of Winwick, as it was related to him by the Rev. G. Chippendale. jNIr. Hornby sent me the letter of Mr. Chippindale, from which I have ex- tracted the following paragraph. " Some years back, probably five or six, a young gentleman of the name of Arrowsmith, a member of the Royal Academy, at* Somerset House, but of what degree I cannot remember, came down into this country, and resided some months in Warrington, in the exercise of his profession, as a miniature portrait painter. He was quite deaf, so much so as to be entirely dumb ; he had been taught to write, and wrote an elegant hand, in which he was able to express his own ideas with facility ; and was also able to read and understand the ideas of others expressed in writing. It will scarcely be credited that a person thus circumstanced should be fond of music, but this was the fact, in the case of Mr. Arrowsmith. He was at a gentleman's glee club, in Warrington, of which I was President at that time; and, as the glees were sung, he would place himself near some article of wooden furniture, or a par- tition, door, or window-shutter, and would fix the extreme ends of his finger- no Another argument has been advanced in proof of her possessing the organ of vision by her opponents, and has nails, which he kept rather long, upon the edge of the wood, or some project- ing part of it, and there he would remain till the piece under performance was finished; all the while expressing by the most significant gestures, the pleasure he experienced from his perception of the musical sounds. He was not so much pleased with a solo as a pretty full crash of harmony ; and if the music was not very good, or pci liaps I should say, if it was not so correctly executed, he would shew no sensation of pleasure. But the most extraordinary circum- stance in this case is, that he was evidently most delighted with those passages in which the composer displayed his science by modulating in different keys ; when such passages hapi>enedto be executed with precision, he could scar<^ely repress tlve emotions of pleasure he received within any bounds ; for the delight he evinced seemed to border on extacy. This was exi>re5sed most remarkably, at our club, when the glee was sung with which we often con- cluded ; it is by Stephens, and begins with the words, " Ye spotted snakes,'* from Rhakspeare's Midsummer Night's Dream. In the second stanza, on the words, " Weaving spiders, come not here, &c." there is some modulation of the kind above alluded to ; and Mr. Arrowsmith was in raptures at it, such as Mould not have been exceeded in one who wsis in full possession of the sense of hearing. These facts are verj' extraordinary ones ; and that they are facts can be proved by the evidence of six or eight gentlemen who were present, and by turns observed him accurately. I have not heard any thing of him since the time above mentioned ; but it is probable he is yet living, for he could not be more than thirty years old, six years ago. He came to Warrington a stranger, and I think no one here knov.-s either his country or his address, But, as a meniber of the Royal Academy, he may easily be found," AVinn-ick, Nov. 1, 18 17. Mr. Bullock, of London, informed me, this gentleman was known to him. If we reason by analogy, these instances will afford a proof of the substitu; tion of peculiar power in one for the loss of another of our corporeal organs. Indeed it is curious often to observe the effect of any disease or injury acting immediately upon the sensorium, and more particularly in cases of derange- ment. In the former case the most irregular motions, or the most quiescent state, may take place, as the brain is acted upon by exciting or by debilitating f auses. In the latter it mciy give a man, who before was hardly able to perform the common duties of life, h» original and forcible mode of thinking, which, previous to th's deranged action upon the brain was never contemplated. It may transform a man of the dullest ideas into a sublime poet. It may change the character of the most mild, una-ssuming, and modest female, into the most |>as4on:ite, obstrusivC; and salsicious chaiacter. Reverse the circumstance, bv Ill been urged forcibly against her, even by professional men, because they observed the pupil occasionally to contract and dilate. A few remarks upon the construc- tion and action of the Iris, will not, I hope, bo deemed irrelevant. The Iris is the variously coloured circle surrounding the pupil, which, as it were, perforates its centre. It is placed as a curtain before the crystaline lens ; contracts in a healthy state upon the sudden exposure to a vivid light, or when we look at things very near the eye, and dilates in a weak light, or in viewing remote objects. Haller supposed the cause of dilatation to be owing to the abatement of the powers resisting the aqueous humour; and he gave, in proof of this opinion, the dila- tation which ensues from great debility, fainting or death. He thought the contraction might arise from a strong influx of humours, into the colourless vessels of the Iris, by which the said vessels are extended together with the Iris, which is thereby elongated, so as to shut up the greater part of the pupil. The size of the pupil conse- quent upon this motion of the Iris appears generally to be connected with the sensation of the retina, and when the internal parts of the eye suffer any injury, we are in- duced to form a judgment from its increased or diminished action of the state of the optic nerve. The Iris was formerly considered as a contintiation of the choroid coat, until examined more accurately by Zinn, who has de- which the derangement was produced, and the direct contrary may take place; the able and thinking mind may become imbecile or idiotic. The sublime poet may dwindle into the mere gabbler. And the most passionate, obtru- sive, and salacious female may becoine mild, unassuming and modest. ^ o various and unaccountable are the eiFects of nervous influence upon the hiurnin body, that it would be highly arrogant in any man to contradict the assertions of another upon a subject of this kind, unlsts he ci n produce fact? to ot-tablish <,he position he may make "w hich Ci nuot be refuted. 112 scribed it as being only connected with this coat by the medium of the ciliary circle. It is probably the most acutely sensible part of the human body ; being compos- ed of muscular fibres, a profusion of blood vessels, and of nerves. This opinion of the muscularity of the Iris, is confirmed, particularly from analogy, with the Iris, of some species of the Parrot, which possesses a voluntary power of contracting and dilating the pupil, and from muscular fibres having been observed in the Iris, of some of the larger animals. Other anatomists deny the mus- cularity of the Iris, and Wrisberg, in dissecting that of an Ox, affirms, no muscular fibres could be seen, and he thought sufficient proof had been advanced against its muscularity, in the fact, of it not contracting when light falls upon its surface. The abbe Mariotte, who opposed Descartes, and other philosophers in the supposition of the retina receiving the impression of light, and conveying it to the sensorium, was the discoverer of this curious fact, that when the rays of light fall upon the centre of the optic nerve, they give no sensa- tion. He also supposed the choroid coat to be the seat of vision, in which opinion he was opposed by M. Pec- quet. And M. de la Hire, has attempted to adjust the dis- pute by supposing the choroides to receive the impres- sion of images, in order to transmit them to the retina. M. le Cat, supposed the choroides to be a production of the inner coat of the pia mater ; and he supported this opinion of Mariotte, from believing that the pia mater itself and not the nerves, was the proper instrument of sensation. He supposed the retina to answer a purpose similar to the cuticle which covers the pyramidal papillae, forming the immediate organ of feeling, or that of the porous membrane, which covers the glandulous papillae of the tongue ; and he only allows the retina to receive the 113 impression of light, without being sensible of it, to mode- rate it, and to prepare it for its proper organ. I am diverg- ing in some measure from my subject, but 1 cannot help observing upon this point that the opinions of Mr. Mi- chell are strongly in favour of the choroides being the seat of vision, and Dr. Priestley says his arguments had more weight with him than he was at first either able to per- ceive, or willing to acknowledge, in those of the French philosophers, although he afterwards allows that several considerations, which had occurred to him, were favou- rable to the retina being the seat of vision ; and that M. de la Hire's argument in favour of the retina, from the analogy of the other senses, is much strengthened by considering that the retina is a large nervous apparatus, immediately exposed to the impression of light; whereas the choroides receives but a slender supply of nerves in common with the sclerotica, the conjunctiva, and the eyelids ; and its nerves are much less exposed to the light than the naked fibres of the optic nerve. Dr. Monro adhered to the notion of the muscularity of the Iris, and he attributed the circumstance alluded to by Wrisberg, to the colour or paint upon the Iris, which acts as a cuticle in preventing the light from irri- tating it. This pigment, being washed off, the Iris exhibits two sets of muscular fibres, concerning which various opinions have been formed. The one set in the shape of radii, the different colours of which give the diversity of colour to the eye ; the other circular surrounding the inner edge of the Iris, which Dr. Monro considered as the sphincter muscle of the pupil. Haller asserts these concentrical orbicular fibres of the pupil are neither visible to the eyes, nor by the microscope, not even in an ox, as far as he had been able to observe ; he allows however there is one distinct ring of obscure p 114 fibres in the body or inner margin of the uveal circle. Mr C. Bell's preparations shewed so g-reat a degree of vascularity in the Iris, that he was ready to believe its action to be produced by a vascular structure, but when he observed the profusion of nerves in other instances, obscured by injection, he could not but allow the muscu- lar fibres might have been obscured as the nerves were. He observes also, the retina is in a peculiar manner sus- ceptible of the impression of light, but he cannot wonder that light should not stimulate a muscle to contraction, when we have every proof that it has no effect upon the delicately expanded nerve of the other senses. He sup- poses the Iris is only to be affected through the sensation of the retina, or perhaps rather by the effect communi- cated to the sensorium, and he gives in proof of this opinion, that in couching he has repeatedly rubbed the side of the needle against the Iris without exciting any motion in it. He has seen it pricked slightly by the needle, without shewing any sign of being irritated, and what appeared to him a convincing proof, when cut it fell before the knife in extracting the cataract : and in this last instance, far from being stimulated to contrac- tion, it hung relaxed. It is evident then, he says, that no common stimulus applied to the Iris has any sensible effect in exciting it to contraction ; and that it is subject only in a secondary way to the degree of intensity of light admitted to the retina. The violence of pain occasioned by the inflammation and other symptoms consequent upon prolapsus of the Iris, is extreme in the early stage of the disease, and marks great sensibility of the Iris. Is it not probable therefore the more violent action of the knife or needle upon parts so extremely delicate, may so destroy, as to render them totally incapable of any contraction ? It 115 is a proof of delicate sensibility from what Mr. Wardrop ingeniously observes, that perhaps the motions of the Iris have some analogy to those motions in plants which are produced by the sun's rays. Its motions in the eye where there is a complete cataract, or where the aperture of the pupil is drawn aside from a part of the cornea which has become opaque, till it gets opposite to a trans- parent portion, makes this opinion probable. The Iris too in many cases retains its power of contraction and dilatation even where the retina is completely insensible, so that it is likely that its motions do not altogether depend upon impressions made on the retina. jVlr. War- drop illustrates the former part of this opinion by the relation of two cases, in the first an adult who had lost the sight of one eye, and had a large speck formed on the temporal and central part of the cornea of the other eye soon after birth. The pupil was very considerably dilated towards the nasal part, which remained transpa^ rent, so that by this effort of nature, in drawing the pupilar opening from the opaque to the transparent part of the cornea, the patient was ^ble to guide himself through the streets, and in twilight he could see large objects around him with considerable accuracy. The same thing also took place in a young woman's eyes, under precisely similar circumstances.^^'' From its great vascularity, there can be little doubt that muscular fibres do exist in Ihe Iris.f * Vide Wardrop on the human eye, vol. I. page 83 and 4. t Haller, on the other hand, denies that the Iris possesses rnuscular fibres : he refers the cause of the contraction and dilatation rather to the blood vessels than to muscles. Sir Edward Home informs us, that he had seen in the possession of Br. Baillie, an injection of the vessels of the memhrana tyrnpani, which appear- ed nearly half as numerous as those of the Iris, from which he endeavours to^ prove the existence of muscular fibres in the membrana tympani, as they 116 In general the movement of the Iris is involuntary, but terror, sudden fright, and the more violent passions of the mind, affect it. It is dilated in the cat when roused to attention by the scratching of a mouse, or when it strug- gles to escape from any restriction it may be placed under. It is proved in a variety of cases, that although the retina is dead to the impression of the rays of light, this contraction and dilatation frequently occur, some- times in an equally rapid way, as when the organization of the retina is perfect, and its sentient qualities in their most active state. We cannot therefore depend upon the activity of the Iris, as a certain proof of vision in all cases, and more especially as our opinion on this point is supported by certain facts which cannot be set aside by a simple contradictory assertion, or a bare denial. It is well known that amaurosis or gutta serena, pro- ducing a partial or complete loss of sight, may be occa- sioned by acute as well as chronic diseases ; it may be produced by external injury, by cold, by excessive heat, by exposure to the too vivid light of the sun, by light- ning, by the stimulatiog effects of concentrated acids applied to the nose, by the sudden suppression of the catamenia, by apoplexy, by worms, by a deranged state of the stomach and bowels, and by all those causes which, acting directly or indirectly upon the brain, pro- duce an obstruction of the nervous fluid, which, as is generally supposed, for the purposes of vision, should cannot be discovered by dissection. Upon a similar basis, we may therefore, reasonably suppose, that not only muscular fibres, but that nerres, which were equally obscure, might be also distributed to the Iris. Although Haller and Other writers have denied that the Iris possesses an}-- great degree of sensibility, yet it is not probable this denial will satisfy Physiologists in general, because the Iris certainly possesses motions, not only the most delicate but sensible, whether caused by the action of light, or excited by any other agent. 117 pass through the optic nerve into its minutest expansion. We are so little acquainted with the structure and func- tions of the brain, that we are often surprised upon dis- section, to find tumour, abscess, or some extraneous substance, irritating only a part of the brain, distant from the optic nerve, produce blindness. We are less surprised when it is preceeded by symptoms indicat- ing the accumulation of fluid in the ventricles, or between the meninges of the brain, or by hydatids, by extravasation of blood, or by tumours pressing upon those nerves at their origin, or before they pass through the sl^ull. If pressure be made upon the nerve, previous to its division, blindness may take place in both eyes ; but where it is only applied to the optic nerve of one side, it will probably cause only blindness in that eye. Upon examination of the optic nerve, after death, it does not follow that any difference appears between the optic nerve of the blind or of the sound eye. This also may sometimes be the case, where both eyes are blind, for the cause of blindness is not always ascertained by dissection. Many instances however are mentioned by authors where sufficient proof has been given after death of the cause of blindness ; and some have occurred where the optic nerves have been materially altered in their appea- rance, and yet blindness has not taken place. It has been observed by authors that the reciprocal sympathy between the eyes is so active that no person anxious to obtain either physiological or pathological knowledge, should for a moment forget it. This knowledge is more particularly useful in the examination of cataract ; and it is of the highest importance to keep one eye entirely secluded from the light, while the surgeon inspects the state of the Iris of the other ; for the very impression of the rays of light upon one eye, sensible to this stimulus is known to be often sufficient to produce corresponding 118 motions in the Iris of the other eye, although it is ascer- tained that that eye is in a perfect state of amaurosis. This circumstance has been explained by the decussation of some fibres from the optic nerve, at their union ; but there are instances mentioned when the optic nerves have descended without any union during their whole course, and the sight was perfect in man, in some other animals, and more particularly in fishes.* It is well know that contraction and dilatation exist in those cases where cataract is so complete as to cause total blindness, or at least to prevent the transmission of light to the retina, but in their more advanced stage the pupil is sometimes more dilated, and the Iris moves very slowly and inertly, because the cataract or diseased chrystaline lens touches the Iris, and impedes its action. But Baron Wenzel informs us there are other examples of cataract in which the pupil may be quite motionless, and yet sight will be restored after the performance of the operation, a proof the motions of the pupil are not solely guided by the sensibility of the retina, but are influenced by other causes. Mr. Samuel Cooper, in his very valuable surgical die-? tionary, makes a supposition of cataract existing, where gutfa Serena was complete in both eyes, but in which • Nervi optici in Raia pisce modo peculiar! a cerebri basi orti, et poster trochle;i quadam communiti, separatiip ad oculos deferuntur — " "Vide Byigg's Opthalmographia. Edit. Cantab. 1676, page 71- It was the opinion of Sir Isaac Newton and others that objects appear single because the two optic nerves unite before they reach the brain, but some anatomists have observed that the optic nerves do not mix or confound their substance, being only united by a close cohesion ; a.x^6, objects have appeared single, when the optic nerves were found to be disjoined. — in homine ver-') et quadrupedis arctissime (in piscibus tamen per simpliceaa solununodo cont actum) uniuntur.— Vide Briggs ut supra. ► 119 there were the freest contraction and dilatation of the pupil, and of the consequences which might result, if a surgeon, induced by the moveable state of the Iris, were to undertake an operation, under such circumstances, for the removal of the cataract, as it would be unavailing-, from the rays of light having only been transmitted to an insensible retina. Wenzel and Richter, both notice these peculiarities, and the former refers the circumstance to the Iris deriving its nerves wholly from the lenticular ganglion, whilst the immediate organ of sight is consti- tuted entirely by the optic nerve. The best operators for cataract are also of opinion, that the distinction of light from darkness, as to the prog- nosis of the result of the operation, is of much more con- sequence than the motion of the Iris. In many cases of amaurosis, where the retina is entire- ly destroyed, the pupil becomes immoveable, dilated, and of its natural black colour ; sometimes it has a dull glossy, muddy amber, or horny appearance ; at other times it is greenish ; now and then whitish, and opaque, so as to be liable to be mistaken for an incipient cataract. The symptoms of amaurosis are however very irregular, some- times in the most complete and incurable cases, the pupil is of its natural size, and even capable of very free mo- tions, and occasionally it is actually smaller, and more contracted. Richter asserts, that in particular instances, the Iris not only possesses a power of motion, but, is ca- pable of moving with uncommon activity, so that in a very moderate light it will contract in so unusual a de- gree as nearly to close the pupil. Mr. Samuel Cooper, mentions two or three remarkable instances of the very active state of the Iris in cases of amaurosis which were shown to him by Mr. Albert, surgeon of the York 120 Hospital, Chelsea ; he had seen others also, in St. Bar- tholomew's. Similar cases may be seen, occasionally, in every hospital. I have observed them in our Infirmary, and in the Blind Asylum. Mr. M'Donald, house surgeon of the Edinburgh Hospital, mentioned to me, a similar case in that Hospital. The patients above alluded to, had, most of them not the least power of distinguishing between total darkness, a candle placed before their eyes, or the vivid rays of the sun. Similar facts have also been related by Janin, Schmucker, and other writers. Mr. Lucas, of Leeds, in his paper on cataract, has mentioned the family of the Rev. Mr. Hall, of Leaven, near Beverly, in Yorkshire, consisting of five children who \vere all born blind ; none of them could distinguish light from darkness, although the pupil was in common neither too much dilated nor contracted, yet it had motions which did not seem to depend upon the usual causes, but were irregular. They were in different degrees ideots, and one limb or other was in perpetual motion in a manner resembling St. Vitus's dance ; from which Mr. Lucas supposed there was some peculiarity ii? the structure of the brain.* Whether the opinion of the generality of philosophers who make the retina the sole organ of vision 5 of those who formerly supposed the ehrystaline lens the best adapted for this purpose ; of the Abbd Marriotte and others, who thought the choroid coat to have this influ- ence, or of the few who might imagine the other parts of the eye, and more particularly the choroid, the ciliary processes and the Iris to be aiding in this important office, be correct or not ; it is curious to observe how wounds • Vide Medical Observations and Enquiries, vol. 6. 121 of the ciliary processes produce blindness, if there b^ not some peculiar connexion between them, and the optic nerve during the operation of vision. Whether this effect be produced by an immediate impression upon the sensorium, communicated from the nerves distributed to these parts, and acting immediately from the brain upon the optic nerve, at its origin, may be doubtful ; but it seems as reasonable to suppose this effect as to imagine the blindness to have originated from the communica- tion which may take place through the slender filaments, which are distributed to the outer coat of the optic nerve before they join another filament of the third pair, pre- vious to forming the opthalmic or lenticular ganglion. A wound of the frontal branch of the fifth pair of nerves is very often followed by a variety of nervous symptoms and frequently by complete blindness, with great dilata- tion of the pupil. Mr. Wardrop has seen several cases of wounds which punctured the sclerotic coat, followed by a complete amaurosis, accompanied with a pupil very much dilated. In such cases, he says, it is probable that the ciliary processes were injured ; affording an additional proof of the accuracy of Beer's observations on the danger of such wounds in operations of the eye, From the facts adduced above, it is certainly reason- able to infer, that the motion of the Iris is not an infal- lible symptom of the sensibility of the Retina ;=* and • I have just seSn one of the sons of Mr. Squires, of Walton Lodge, near Liverpool, who was struck upon his temple, by the contents of a pistol, com- posed of chewed paper and sand, formed into small wads, which was fired by another boy, on the fifth of November, 1817- He, at the moment, fell down as dead, and from that period his right eye lost the power of vision. The adjacent soft parts were torn to pieces, and portions of the temporal bone came away for several months afterwards, so that little doubt exists that blind- ness took place from the nerve having been lacerated. The pupil of the blind eye contracts and dilates upon exposure to light, or from pressure of the 123 that this appearance of contraction and dilatation of the pupil, upon which certain individuals particularly found- ed their opinion of Miss M'Avoy's possession of the sense of vision, may, in this case, have led them into an errone- ous conclusion. Previonsto my attendance, MissM'Avoy had been for along period seriously indisposed, and for nearly twelve months had been affected with a severe pain in the head. The firing- of the guns at the Fort, on the 4th of June, 1816, considerably aggravated this symptom, producing a throbbing and beating sensation. She was affected with giddiness, and staggered in walking across the room; the vessels of the conjunctiva were filled with red blood, but the action of light produced little un- easiness. With the left, which at an early period had suffered more from inflammation than the right eye, she could scarcely distinguish any object ; and with the right eye for several days, before I saw her, every object at a distance, appeared white and those which were near double. =*= finger upon the eye-lid. Both the pupils were larger than natural, and upon exposure to the light of a candle, it contracted in the sound, in rather a greater degree, than in the blind eye. It is more perceptible in the blind eye, when exposed to the light of the sun, than to that of the candle. In presenting the point of the finger suddenly to the sound eye, the eye-lid moved very quickly ; a similar movement, also, took place at the same time, from sympathy in the blind eye, when the finger was presented ^vithin the visual range of the left, or sound eye; but if this eye were co\'^red, or the finger pointed at the right eye, out of this range, this sensibility of the eye-lid did not occur. Mr. Davidson, of the Infirmary, was present at this examination — June 2, 1820. • Since the publication of the narrative Miss Johnson, a respectable school- mistress, with whom, about the age of thirteen years, Miss M'Avoy was a scholar, mentioned, upon visiting her during the period when she was able to ilistinguish colours, that she recollected having punished Miss M'Avoy for rtrading the same words twice m'cr, and she supposed afterwards, itmusthame been owing to some defect in the eyes. 1S3 On the 5th of Jane, 1 visited her for the first time, and I was led to imagine from these symptoms, that oppres- sion of the brain existed. In the afternoon of this day, Mr. Thomas, the ordinary medical attendant of the fa- mily, was sent for, in consequence of the leeches, which had been just applied, producing syncope before they bad had time to gorge themselves with blood. They were immediately taken off, and on the 6th of June, he observed her to be blind. On the following day I again visited her, and found the pupils considerably dilated, in- sensible to the action of light; her actions indicated blindness, and she could not move without assistance, from place to place. The pain of the head was very acute ; the pulse feeble, irregular, and frequent. On the 9th of June she was seized with convulsions, and in the course of that day, became paralytic on the right side. On the i2th she appeared so much exhausted, that we did not expect her to survive through the night. At three o'clock p. m. of this day, she was observed to gasp for breath, and. evidently to labour under a sense of suf- focation from fluid passing down into the stomach. Her weakness was so excessive, she could not exert herself to eject from the mouth any part of this fluid until the 16th instant, when about seven ounces were obtained ; a part of which was afterwards submitted to Dr Bostock's ana- lysis, who found it to be of that nature denominated Al- buminous, in every respect resembling the fluid which is eiFused in ascites, and in various species of dropsy. He observed it dilFered from the fluid formed in hydrocepha- lus by containing a larger quantity of animal matter, but at the same time its solid contents were less than those of the serum of the blood. Soon after this dis- charge took place the convulsions ceased, but recurred again on the 2d of July, and were again relieved by a similar discharge, but in a much smaller quantity through 124 the nostrils. I need not enumerate the different attacks of convulsions and their termination^ as they are al- ready stated in the narrative, or the continuation of her case ; let it suffice to say, she has never, from her own account, been entirely free from head-ache, more or less severe, frequent pains across and in the sockets of the eyes, and she has been afflicted with convulsions and other various disease to the present time.^ The pupils were insensible to light, did not contract or dilate until nearly four months after she became blind; and since that period the contraction and dilatation has been very irregular. Sometimes the contraction has been so g-reat as to diminish even the diameter of the pupil to an unusual degree ; whilst, at other times it was scarcely acted upon by light in any form, or by pressure of the finger, which now and then occasioned contrac- tion and dilatation, when the approach of a candle pro- duced no effect;. The pupil is often observed to remain dilated, when (exposed to a bright light, and I have seen the right eye in an obscure light, dilated as if belladonna had been applied to a sound eye, when the left eye was only di- lated, as it commonly is, to about one third part of the extent of the Iris. The substances which act most decisively in dilating the pupil, as belladonna and hyoscyamus, do not pro- duce their customary effect upon the pupils of Miss M*Avoy's eyes. Indeed, I have sometimes applied the • From what cause has it happened, that Mr. Sandars and the greater part •f her opponents have scarcely noticed circumstances of so important a nature, or at least have passed them over in a manner to induce the public at a distance *o suppose they never had occurred ? 125 one or other of these extracts without producing any material change ; whilst at other times a greater dilata- tion took place on the next day. Once on the following day, after the application of the belladonna, the pupil appeared elongated from above downwards, like the pupil, in the day time, of one of the feline species. In this case, blinking is not produced by the exposure of the eye-balls to the vivid rays of the sun. The solar spectra, thrown in their most brilliant colours, and with their most rapid vibrations upon the eyes, were received without winking, or shewing any sign she was aware of them, except as some of the colours gave her a sensation of more or less pleasure, but her eyes remained equally firm and motionless. Contraction, but generally in a slower degree than usual, occurs often when a candle is brought near ip the eye, but sometimes it produces no effect. The cornea was generally insensible to the application of any substance. Mr. Thomas, as mentioned in the Narrative, placed his finger on the pupil, and Miss ]Vl*Avoy did not appear to have felt it. Mr. Bedford pressed a probe on the cornea, without exciting any pain, unless when he touched the eyelids. A similar experiment was tried by Dr. Jardine, and also by Mr. Davidson, house-surgeon of the Infirmary, but in both cases a little apprehensiveness was observed ; and a tear or two passed over the eye-lid, when the latter gentle- man made the experiment ; but this circumstance appear- ed to me to arise from their having touched the eye-lids, which were sore and tender, from the meibomian glands being diseased and discharging matter. Miss M*Avoy pass- ed her finger over the cornea, and Dr. Jardine rubbed the probe across the cornea and pupil of each eye, but ,126 not a tear escaped, nor was collected in the eye ; and indeed the cornea was depressed before he observed he had touched it. Mr. Davidson, at another time, having no probe, made use of the upper end of a closed com- mon lancet, but it was rather too coarse an instrument to apply without touching the eye-lash or lid. I again made use of the head of a large pin, which I laid on the pupil, but the eye 'ball moved, and Miss M'Avoy said I had touched the eye-lid, which I have no doubt was the case, as I afterwards placed on the pupil, pressed upon it, and rubbed across the cornea, a leaf cut for the pur- pose, when I rested my hand, and the eye-lid was gently held up without producing the slightest motion in the eye-ball. Mr M'Donald, of the Edinburgh Hospital, repeated this experiment with a similar result, and I have several times since done it without exciting the least apparent sensibility. Philosophers of the earliest times employed as a most effectual test, the sudden passing of the hand, or finger across the eyes, and the efficacy of this test has been con- firmed by Morgagni, by other Anatomists, and by the ac- tual practice of Oculists of the present day. It has how- ever been objected to, by the opponents of Miss M'Avoy, as a sufficient test, because instances have occurred, where by a strong effort of the will, and probably when they were aware of the experiment to be made, blinking did not take place upon the presentation of the finger or hand. Under such circumstances, it might so happen, but when it is applied unexpectedly, the experiment will seldom fail. This has been tried in every possible way upon Miss M'Avoy, and the result has been uniformly in her favour. If any further confirmation upon this point be necessary, I can state, that not a muscle, or fibre of a muscle of her face was moved, nor a symptom of fear ex- 127 pressed when I presented a pistol at her head. A similar experiment, and with a similar result, was made by Mr. Nairn, and Mr. Udney surgeons in Liverpool, and I be- lieve, at this moment, neither Miss M'Avoy, nor any of her family, is aware of such experiments having been made.=* In the presence of Dr. Nimmo, of Glasgow, Captain Owen, of the Navy, a pistol which I gave to Mr. Gladstone, for the purpose, who was one of the party, I believe was presented at her, by him, but not at the mo- ment being present, those gentlemen will state the result, and I have no doubt it will confirm that made by me, and the other gentlemen.t The same pistol I presented at Miss M*Avoy, I levelled at a gentleman upon a visit with me, after mentioning I had tried a curious experiment upon her that morning, but the result was very different; he nearly fell from his chair. A Noble Duke, deceased, I have been told, was in the habit of trying the fortitude of his guests in this manner, but he never found but one man (and that a Poet,) who could stand the brunt of a presented pistol, without an ex- pression of fear. I hardly think that Pyrrho, mentioned by Diogenes Laertes, whose constancy was so great that he suffered" incisions and cauteries to be made upon his body, but was never observed to wink his eyes, would have been able to avoid blinking upon the sudden application of a pointed or other instrument to his eyes, however firm he might be ; because the motions of the Iris in man • This circumstance had been mentioned to two ladies who visited her aboul the middle of last month, and they by accident mentioned that this experi- ment had been made. April 5th, 1820. f I have since understood from Mr. Gladstone, that the result w;;s s'milai- 1 j that which I had stated, and that 'be party had no doubt of her blindnes^j, ^8 are involuntary, and do not depend upon mental intre- pidity. In fine, all those experiments which have been usually made to ascertain if blindness really existed, have been tried in this instance, and have convinced me of the fact. It appears also, that the proofs above relat- ed are sufficient to satisfy the mind of any reasonable per- son, that Miss M'Avoy's blindness commenced at the period mentioned; and, from the causes still existing-, which shew material derangement in the brain, and in the nerves, we may safely conclude blindness still exists. From the length of time in which the sensibility of the retina has been destroyed, and from the frequent attacks of violent disease, some alteration in the appearance of the eyes, and constitutional character might have been expected, but the change is less than one would have imagined, although it is observable, for a little time> after an attack of convulsion. The moveable capability of the eyes is certainly im- paired, and the muscles appear to have lost their volun- tary action, as in endeavouring to raise her eyes to the ceiling, she has not the power of doing it, nor of de- pressing them to the ground. The eye-lids fall over the eyes when she attempts to turn them downwards ; but if a person attentively observe the pupil, by looking under the eye-lids, the eyes will be seen in the same position as they were before the attempt was made. The motion of the eye-ball, inwards and outwards, is not so free as is natural, but it takes place to a certain extent. When convulsed, however, the eye-balls are observed to be turned upwards, to move to and fro, and even when the suspension of breathing comes on, the eye-balls sometimes move, and cause a tremulous agitation of the eye-lids, perceptible to an observer. 129 Upon raising the eye-lid, I have felt a slight resistance, whilst at other times the eye-lid was raised and fell as if totally insensible. If Miss M'Avoy be not excited by the conversation or the society of agreeable friends, the eye-lids fall down and almost cover the eyes as if she were about to sleep. On entering the parlour, during the state of insensibility in which I have found her, I have observed this more particularly, and she has often not even raised them, although she had recovered from several attacks of convulsion or suspension of breathiog, until she found, by some one speaking to me, or when I spoke to her, that I was in the room. During this period of suspension of breathing, she is perfectly insen- sible to every thing which parses, but the circulation in the wrists continues nearly in the same manner, as when she is free from it. The period of suspension in these last attacks varied only from 15 to 45 seconds ; once it has been mentioned in the Narrative, this suspension continued for ninety seconds. When she is desired to direct her eyes to the place where any person sits, and which she knows from hear- ing him speak, it would appear to an indififerent observer, she looked apon it, but if the pupil be watched atten- tively, it will be frequently seen not to be in the direct line of vision. There is also generally an amaurotic appearance in the eye, more particularly if she be kept quiet, and not stimulated to any exertion. If her cap be taken off, and the general contour of the face and head be attentively examined, I have the most perfect con- viction that experienced Physiologists, Anatomists and Oculists will coincide with me in my opinion of her blindness. Mr. Gough, of Kendal, and other gentlemen, who R ISO have never seen Miss M'Avoy, have argued against the possibility of her possessing the powers related in the Narrative, but " facts are stubborn things," and the in- fluence of opinions, founded upon mere theory, cannot ultimately prevail against them, however they may be obscured for a time from public view. Reason and truth are often overwhelmed by prejudice, but " non pudet physicum, id est, speculatorem, venatoremque naturae ab animis consuetudine imbutis petere tes- timonium veritatis ?'* From the earliest times theories have existed, which have formed the basis of the philo- sophy of that particular sera ; these have been exchang- ed for others as soon as their futility was exposed, and even those of the present day will pass away un- less they have their foundation in experiment and fact. I shall pass over the observations of Mr. Gough, upon* the ingenious mode in which he supposed it possible imposition might be practised by Miss M'Avoy, with the simple remark that he should have taken care to have had a better foundation for his assertions, before he implicated her friends, and her medical attendants as auxiliaries in the deception. I have taken all the pains in my power to investigate her own conduct and that of her friends, during a period of more than three years, and I am perfectly convinced no imposition either ex- isted or was attempted. Her mother, Mrs. Hughes, is a woman of a communicative disposition, not refined in her habits, but industrious and civil, unless when roused into warmth of expression and feeling by any conduct which gave pain or uneasiness to her daughter. If there be one woman less adapted than another to carry on imposition in a case of this nature, I think Mrs. Hughes would be the person I should point at. The 131 step father is hasty in his temper, but possessed of that sort of pride which would prevent him from lending his aid to any attempt at imposition. He has had several children by Mrs. Hughes, one of whom died lately, from the efifects of psoas abscess ; one who is ricketty ; another of a consumptive habit; and two who are in tole- rably good health, but are of a strumous diathesis. They are very young, and require the care of their mother, and she appears to have afforded it to the utmost of her power ; but the superior sufferings of her eldest daughter may have influenced her to pay this daughter an extraordinary degree of attention, which has some- times subjected her to the displeasure of her husband. From the observations I have made, it appears to me Mr. Hughes felt irritated by the frequent visits of stran- gers to his house, and many of those comforts, which a quiet home afforded, were at those times denied to him ; and to have put a stop to them, he would gladly have discovered imposition if it really existed. After the Wavertree meeting he took a great deal of trouble both separately and in conjunction with his wife, to dis- cover any trait indicative of deception in his step daugh- ter, but these repeated trials only confirmed him in the conviction of her integrity. This evidence from a step father will probably be esteemed stronger by the world in general, than if it had been given by her own father, who might be supposed to have been influenced by his paternal feelings, in not making so strict an enqtiiry. In this case I have not been able to discover any object Miss M'Avoy or her friends could have in practising imposition upon her medical attendants, and upon the public. Her opponents, indeed, have asserted, that Miss M'Avoy or her mother, has received money in considerable sums, and that this was a principal aim in the admission of strangers to visit her; but if even this 132 were the case, although it might throw suspicion upon her motives, it yet could not do away with the strong evidence of her blindness, or of her having possessed peculiar powers. If my information, however, be cor- rect, they can produce no witness in support of their assertion'] Is it to be believed, they would not have long ago declared the particular instances of money having been given, if the assertion were founded in fact? I have the authority of the parties to say, they never have received money, and I challenge the traducers of Miss M'Avoy's fame to the proof. This assertion has most probably originated in the supposition, it might be so ; by being bandied about from one to another, it has at last assumed a positive form, and were it to be retraced to its source, it would be found to have as much truth in it as in the old story of the black crows. The account I have given in the continuation of the Narrative, of some pieces of silver which were left in the hands of the Rev. Mr. Vincent Glover, by Lord Lilford, for the avowed purpose of purchasing fruit for Miss M'Avoy, and which were returned to his Lordship, is the only exception ; but Miss M'Avoy's refusal to receive the money, and her conduct upon that occasion are perfectly satisfactory she had neither taken money before, nor was it her intention to retain it at this time. The presents received by the parties at different times, have been excessively magnified ; but I believe they may be all comprised in half a pound of tea from Mr. Egerton Smith, the editor of the Mercury ; a few bottles of wine brought by Mrs. Pentland, for Mrs. Hughes's own use, who was near her confinement ; some game from Mr. Blundell, of Ince ; and a little fruit from one or two other persons who visited her. in The situation of life of the parties is that of mediocrity. Their income is rather more than £200 per annum, a sufficient competence for every rational purpose ; and it will at least afiford the comforts to a family living in their retired way, if it do not allow of the luxuries of life. Independent of this income, Miss M*Avoy has about £460. The testimony of her friends, who had the most fre- quent opportunities of studying* her temper, is highly in her favour ; they speak of her mildness of manner; the goodness of her disposition ; her strict adherence to truth ; and her attention to her religious duties. The Rev. Edward Glover, her former confessor, who is a mild, a respectable, a conscientious, and a sensible man, gives his sanction to her possession of all the qua- lities above enumerated, and his evidence is a host in itself. He has observed to me that the friendship she always expressed for him, the confidence placed in him, the gratitude she felt for his religious instruction, and the sincerity with which, under her awful situation, she conversed with him, when preparing her to appear be- fore the God of truth, must place any sUi;picion of fraud beyond the possible range of human delinquency. She has nearly attained her twentieth year, has had little communication with the world, previous to the discovery of her peculiar powers, and possessed of a character, which those friends, who know her best, have given, and to which I can testify, by my own experi- ence of the general tenor of her conduct since I have known her, it is not likely she would attempt imposi-- tion ; but if she had done so, I think it would have been Mill more extraordinary if I and others, who have most 1S4 attentively examined heir every action, had not found it out. I have made enquiry also into her intentions, if it may please the Almighty to restore her to health, and she informs me it has always been her wish to become a Nun ; but her mother will not consent to this plan^ until she arrive at the age of twenty-four years, when felie will yield to her wishes, if her daughter still con- trniae in the same mind. If she recover, and attain •this age, she tells me it is her intention still to pursue this plan. Some of her opponents have imagined a de- sign connected with her religious faith, and that her peculiar powers were only assumed for miraculous pur- poses; and this intended designation of her life might appear a confirmation of this opinion, but 1 am confi- dent no such intention was ever contemplated by her- self or her friends, and that the idea of becoming a Nun originated in the innocent wish of a calm and resigned mind for a quiet and retired life. Let any one look at this poor girl, labouring under a most tormenting disease, which has prevented her from lying down for more than two years, in an horizontal po- sition ; who, for the same period, has not known the com- fort of a bed, or of undressing herself, but for the purpose of cleanliness, afflicted with a severe and constant head* ache, with a tumour in the side, so painful that the least pressure distressed her for hours, with anasarcous swell- ings in her legs, which frequently required scarifications, to be made, to give her temporary relief, with occasional oppression, and frequent catching in the breathing, a convulsive motion of the diaphragm, and with the almost constant dread of dissolution. Let her opponents say that a female of her general character, and afiicted in so seri- • 135 ousa manner, can deceive, and I will not hesitate to declare those breasts callous to the common feelings of humanity, which can hazard such a suspicion : to attempt argument with men of this description, would be futile in the ex- treme, and no one, whose motives are good, and ho* nourable, will envy them their feelings. UPON The PAMPHLET of Mr, Joseph Sandars, Entitled « HINTS TO CREDULITY;" Upon the Letters and Observations of Mr. Egerton Smith, and other Unbelievers in the Povyers possessed by Miss M'AvoY, and in the Fact of her Blindness. w. HEN assertions are positively made, and seeming proofs brought forward by persons of presumed respecta- bility, it is difficult, however erroneous they may be, to refute them. It is a duty I owe to Miss M* Avoy, to those who have witnessed her powers, and to myself, not to al- low them to pass current, without a full and fair exami- nation. The boldness with which they have been ad- vanced, and the pains which have been taken to promul- gate them, have given them a position in public opinion, which truth does not always attain, without these adven- titious aids. I am well aware it is an arduous task, to convince men, who are prejudiced before they enter into the investigation of any doubtful fact ; nor will they al- ways allow themselves to be wrong, when they have in- vestigated it. In the progress of their examination, this prejudice often biasses their judgment, so as to obscure the truth. It is a weakness to which human nature is too often liable; therefore, I do not wonder it should ex- ist in this very peculiar case, and that doubts of the fact should have arisen^ but I do not regret it, as it has given 138 me an opportunity of re-considering the grounds upon which I formed my opinion of Miss M'Avoy's blindness It is certainly less detrimental to the interests of science, that sceptical should prevail over credulous opinion ; but it may be carried too far, when it endeavours to do away with the evidence of the senses in cool and dispassionate inquiry. If Miss M*Avoy be blind, which the preceding inquiry attempts to prove, the possession of the powers ascribed to her, must be allowed, and it will become a subject of importance in the Philosophical world, as well from its connexion with the theory of vision, as with the physiology of the varied powers of touch. I have been led into the above remarks by the very great pains which have been taken to bear down every proof favourable to Miss M^Avoy; and by the par- tial manner in which some of her opponents have com- mented on the facts in the Narrative. Mr. Sandars, and Mr. Egerton Smith, have taken the lead, in endeavour- ingto influence the public against Miss M'Avoy ; the first in a pamphlet, entitled ** Hints to Credulity," and the lat- ter, in detached pieces, some of them under his own sig- nature, addressed to me, and not a few which are anony- mous, but which are supposed to have emanated from the same persevering source. Had the public not given a sort of sanction to the reception of the positive assertions of these gentlemen, involving the charge of imposition on the part of Miss M'Avoy, I should not have thought it necessary to have noticed either the pamphlet of Mr. Sandars, or the letters of Mr. E. Smith ; as the former seemed to have been compiled partly under the inlluence of some petty feelings excited by Mr. Hughes, in a hasty letter addressed to Mr. Sandars, and against me, for a re- tort made to him, for a paragraph in bis letter to Mr. Hughes, in which my name was implicated. 139 Mr. Smith's letters and remarks, one would think, were intended to do away with the impression made by his letters on this subject, in which were introduced some experiments convincing to every one but himself. As a pamphlet has a more imposing appearance than a letter, I shall give Mr. Sandars the precedence, and enter upon the examination of his proofs of Miss M* Avoy seeing. As my remarks upon his pamphlet commence with the first page, and as I have no other wish in criticising his opinions, than for the purpose of elucidating the truth, I hope my readers will, at the time, refer occasionally to the pamph- let itself; or, if it cannot be easily obtained, to the Exa- miner of the Day, a London weekly paper, the Editor of which, has detailed almost verbatim, the contents of Mr. Sandars's pamphlet, as well as the letters of Mr Gough, and some other writers upon this subject; and to the Liver- pool Mercury, for the letters of Mr. Smith and others. In the first page of his pamphlet, Mr. Sandars assigns the rea- son for intruding himself upon the public, as depending upon the publication of Mr. Hughes's letter, and his answer to it He charges Mr. Hughes with having com- mitted a breach of good manners, in giving it to me, for publication, as the communication was strictly private ; and he assumes to himself a right, which under certain circumstances, migbt be his due, but which in this parti- cular instance it would have been folly to have allowed him, because Mr. Sandars had pursued a line of conduct so totally deficient in respect to Mr. Hughes, that he had clearly deprived himself of the privilege the common usage of society would have otherwise afforded him. The simple charge, as Mr. Sandars has elegantly ex- pressed it, " that your daughter-in-law can see, and that too, with her eyes ; aye, and as well, or better than I can," would not have been of much importance, as it was 140 very evident to the persons present at the only examina- tion of which Mr. Sandars had an opportunity of judg- ing", that he could not draw any just conclusion from liis means of observation. Mr. Sandars, on the public Exchange, in every company with which he associated, and to every person who would listen to him, declared, he had detected Miss M'Avoy as an impostor. Had Mr. Hughes silently acquiesced in this charge of Mr. San- dars, the public would have concluded it to be true ; but being convinced, as he was, of her blindness, it was na- tural he should rebut it : and, if he did so, with a degree of asperity displeasing to Mr. Sandars, he might have ex- cused it, from its similarity with the conduct Mr. San- dars pursued during the examination he made into the merits of this case, on the 24th of September, 1817. Mr Sandars asserts, in the case of Miss M'Avoy, " that blindness has been assumed, declared and believed, that hundreds have flocked to see her ; and under the admi- nistration of regular attendants, experiments have been performed, in the most careless and unsatisfactory man- ner : as the Narrative is very dear in price, and not dis- tinguished for delicacy in its details, the circulation may possibly not be very extensive, it will therefore be pro- per to give to the uninformed some account of the Lady, and of the extraordinary powers with which she is said to be endowed." From this paragraph, the natural in- ference to be drawn, is, that a regular system was adopt- ed in the examinations; but Mr. Sandars, if he had made any proper inquiry into the subject, must have known this was not the case. The true statement is, that hun- dreds of persons visited Miss M*Avoy, made their own observations and experiments (often when no one con- nected with her was present,) and gave their own re- port of them. I was frequently applied to, to meet par- 141 ticular parties, and my good nature ofteu prevailed over my convenience, to consent to the application; but, surely this consent should not be assigned as a reason for drawing the conclusion Mr. Sandars has done. The charge of carelessness in making the experiments must apply to every one who did make them, and probably to no one with greater force than to himself, as it is clear from the information of Dr. Jardine and others, that Mr. Sandars's experiments were hasty and inconclusive. When I recapitulate the principal experiments which were made by the Rev. Thomas Glover and myself, I think 1 shall be able to convince the public of their truth; and that no better plan could have been adopted to se- cure the eyes from the impression of the rays of light, if sight existed, and that in the mode of conducting the experiments, the charge of carelessness was improper and indecorous. If Mr. Sandars meant to put a stop to all enquiry, he could not have devised a better mode than the one he has adopted, of charging me with indelicacy in the de- tail of her case ; but I am not aware of meriting so foul an attack, because I have related nothing, but what, in the report of a very curious medical case, it vvas necessary to mention for the satisfaction of medical readers. =5^ • This charge certainly had nothing to do with the case itself, nor with the proofs of Miss M'Avoy's blindness, or the contrary; and I think Mr. San- dars, in his cooler moments, will rerceivethe impropriety of having made it, as he is not a medical man, and could not therefore be supposed acquainted with the mode of detailing medical cases. I know a little more of Mr. Sandars now than at the time of publishing the Narrative ; and that knowledge will not allow me to suppose he had the least wish of injuring me personally; although he must be sensible no charge could be brought against a professional man, of a more injurious tendency, than that of irulelicacy ; nor would I willingly think Mr. Sandars had done it 142 Had Mr. Sandars wished to enquire into the fact of her blindness or the contrary, he should have marshalled the proofs on each side with equal candour; but his pamphlet is evidently written more with the intention of influencing the public opinion than of elucidating the truth. For several pages he employs himself in quoting, partially, sentences, and he then comments upon them in such a manner, as to throw ridicule upon that part of the narrative, in which are contained circumstances not easily to be explained, if Miss M*Avoy had the most perfect vision. He has however, given her credit for some knowledge of the specific gravities of bodies, and he at the suggestion of any professional man, who might take this mode of assail- ing me, when he would not have dared to do it more openly. Mr. S. might probably be induced to make the charge by the wish to promote the dissemi- nation of his hints, and to deteriorate the sale of the narrative ; for, if his pamph- let v.ere only read, the evidence in favour of Miss M'Avoy would be soon forgotten, and these supposed proofs would have been substituted for the facts in the narrative ; and the public, not knowing the real truth, might be induced, from this cause, to take a decided part with her opponents. Whether the one or the other supix)sition be correct or not, can signify very little now, as the charge has been made, and its effects upon the minds of the public may have taken root. Whether true or false, its dissemination may have cast odium upon me ; for it has been somewhere said that a lie of a fortnight's standing is as good as truth, for the purpose of defaming the good name of any individual. If the great body of mankind thought and judged for them- selves, they would not so easily be induced to listen to the rej>orter of a tale of detraction, or of ill-nature. Such conduct too often occurs, but as far as concerns this charge, I am not conscious of having deserved it, for I have related nothing but what was necessary to the elucidation of a very curious case ; and this relation ought not therefore to have given offence to any well- informed female, as it could not have been esteemed an infringement upon true delicacy ; but where false delicacy and unjust prejudice are substituted, it will be proper to eradicate them from a soil where it may be doubted if they are ever the attendants upon real modesty and decorum. Montaigne has said, " Nous ne sommes que ceremonie, la ceremonie nous emporte, et iaissons la substance des choses ; nous nons tenons aux branches et abandonnons le tronc .et le corps. Nous avons appris aux dames de rougir, oyants sculement nom- mer ce qu'elles ne craignent aucunement a faire : nous n'osons appeller a droict nos membres, et ne craignons pas de les employer a toute sorte de debauche ; la 143 has insinuated that information mig^ht have been convey- ed to her, how to distinguish the heavier and lighter fluids. This insinuation is unworthy of Mr. Sandars. The account he gives of the transaction of the 24th of September, 1817, when he visited Miss M'Avoy, is so very different from that given by Dr. Jardine, Mr. Tho- mas, and others, who were present, that if 1 had really impeached the veracity of Mr. Sandars's relation, 1 should have been borne out by the testimony of those gen- tlemen. Dr. Jardine informed me, when Mr. Sandars tied the goggles over his face, he could not see any thing until he raised his chin upwards, and worked repeatedly the muscles of his face, in a very distorted manner, which at last enabled him to see, so as to name the time of the day by holding a watch highly elevated, close to, and be- ceremonie nous deftend d'exprimer par paroles les choses licites ct naturelles, et nous I'en croyons : la raison nous deffend de n'en faire point d'illicites et mauvaises, et personne ne Ten croit." I should have passed over this remark of Mr. Sandai-s without notice, had not some of my friends told me the insinuation had gone abroad ; it had been disseminated from party to party ; and that some professional men, instead of rebutting the charge, had joined in the censure with those undiscriminating persons who do not consider that the habit of assenting to every thing they heai- is dangerous and slippery. (" 1 11a consuetudo assentiendi periculosa esse videtur et lubrica." ) They ought, indeed, to be cautious how they listen to tales of detraction, lest they subject themselves to be classed with the people Madame de Genlis has thus described, " Dans la societe les satires les plus sanglantes sont faites communiment non par les gens malins mais par les sots et les etour- dis." I wish the facts of this curious case to be generally known and duly appreci- ated, and I have probably subjected myself to the charge of jiedantry, by cover- ing more carefully in a latin garb, those unavoidable sentences which have cal- led forth this discussion, rather than prevent the most fastidious person from reading the continuation of the case of Miss M'Avoy. I trust also, that the candid, liberal and truly delicate female wiir'do me the justice to be- lieve, that in detailing this case I merely followed the customary mode adopted by medical writers, and ought not, therefore, to have been charged with offend- ing against those rules of propriety, which should influence every man. 144 tween the window and his face, with his head turned backwards ! I do not wonder at the goggles not fitting Mr. Sandars, so well as Miss MAvoy, because his nose is particularly prominent, and they were adapted exact- ly to Miss M'Avoy's, not to Mr. San dars's face. Mr. Sandars acknowledges the goggles were once fixed on, in so tight and oppressive a manner, that he could not breathe through the nostrils : but he allowed he was completely blindfolded ! Might it not therefore be probable that they did blindfold the person to whose face they were exactly fitted, without producing great uneasi- ness.^ Certainly, the eyes of the great majority who tried them were blindfolded by the same means. The asser- tion he makes, that Miss M'Avoy's hands are decidedly coarse, can only be believed by those who have not ex- amined them. She has seldom been employed in any work about the house, likely to harden them, and I have observed them more particularly, when her fingers were obliged to be covered, from their tenderness, after she had been engaged in getting up her small linen. Mr. Sandars lays great stress upon her assertion res- pecting the breath, the effect of which I have already explained ; and in observing the absurdity of the opinion, he might have had the candour to have supposed it originated from the nature of her feelings, which were not understood by herself, her medical attendants, or the intelligent men who visited her. He objects to the use of common sticking plaister as a mode of blindfold- ing any person, because, he says, it is of a harsh and inflexible quality ; yet this sort of plaister is used to draw the lips of a wound together, where it is wished to pre- vent a mark from being visible, and it adhered so closely in the different experiments, as to draw the skin after it, 145 as it was removed from surrounding the eyes of Miss M*Avoy. His objection to the use of Burgundy pitch plaister, is conveyed in an insinuation against Mr. Tho- mas, who applied it " at the kitchen fire," but he does not add the words " they (alluding to these plaisters) ad- hered as closely as possible," which concludes the sen- tence ; nor the following : " the silk handkerchief was firmly bound over them." The result of the experiments made on this day, the 2d of July, in the presence of Mr. M*Corquodale, was not mentioned, nor the additional circumstance, that the skin was excoriated, by the appli- plication of the Burgundy pitch plaister around the eyes; a sufficient proof, one would imagine, of its perfect ad- hesion to the skin. Mr. Sandars gives another proof of the eagerness with which he seeks any information, however incorrect, and details it against Miss M'Avoy, when he asserts it was common to use the same tests very often, and that they were kept in the house. The factis, the parties who visited her, frequently produced their own tests, a shawl of variegated colours, a glove, a riband, a ring, a seal, or a watch, were sufficient in the hands of any visitor, for the test required. Those belonging to the house were very rarely used by me : it also very seldom happened that the coverings of gold beaters skin were used twice. I generally brought fresh pieces, when requested to meet any party, and the persons present were almost uniformly satisfied the application was made properly, and adhered as closely as any thing could adhere. Those made use of, when Mr. Sandars was present, were old pieces I had employed before, and which had lost their adhesive qua- lity. He lays great stress upon her eyes being cast down- wards. It is probable he observed the eye-lid only par- tially covering the eye-ball, for if the eye-lid were closed T 146 properly, he certainly could not have seen the eye cast downward; therefore the experiment was only commenc- ing: but, if he had been less hasty, he might have seen that the pupil did not follow the downward motion of the head, but remained stationary, or nearly so, as when sitting up erect. The reason of this gold beaters skin not closely ad- hering, was owing to its having (from being used before) lost its glutinous quality, which forms the principle of its adhesion. The assertion of lier seeing is mere suppo- sition.* In page 2!^ of his pamphlet, Mr. S. doubts the efficiency of the goggles, gold beater's skin, and silk ; but in a note in page 31, he admits " that if the eye-lids be kept firmly and honestly closed, while the skin is drying, they cannot, by any effort of the muscles be opened afterwards, but who will believe the stories about the difficulty of opening the eyes when the goldbeater's skin is taken off? this is a mere trick, experiment will prove it most satisfactorily. It does not require any applica- tion to the eyes, to convince a person he can see, when a bye-stander thinks his eyes are shut; of course the deception may be practised with greater or less facility in proportion to the number and nature of the bandages." The evidence of the persons who visited Miss M*Avoy when these applications were employed, should have been sufficient to convince any unprejudiced man, that this mode of blindfolding was effectual. The eyes were often examined with the greatest circumspection when the first covering was applied, through which the eye-lids appeared completely closed : they were exa- mined again upon the application of the second layer. • Can it be possible, that any serious experimentalist would declare, from a singlte examination, upon such doubtful grounds, Miss M^Avoy could see ? 147 They were allowed to dry, and whoever attentively ob- served them during the whole, or any part of the exa- mination, I am confident never saw the eye balls of Miss M'Avoymove so as to derange the application. When they were taken off, the skin all around the eyes was drawn up with the gold beater's skin. The glutinous matter of the goldbeater's skin, by insinuating itself be- tween the eye-lids, causes them to adhere to each other, and it is assuredly true it did occur whenever fresh pieces were applied to Miss M*Avoy's eyes, so as frequently to oblige me to make use of warm water to soften before she could open them.^ Mr. S. now talks of deception, but how has he proved it in Miss M'Avoy, her immediate friends, or her supporters .^ it is mere assertion on his part, founded on the meanest principle of the human mind, suspicion, more degrading to the liberal and in- dependaut man, than it may be useful to the selfish and worldly minded. Indeed, the teaor of a great portion of Mr. Sandars's pamphlet is to place every circumstance in the most suspicious light, and hints are thrown out which have a strong tendency to effect this purpose. Of this nature is the following remark, *' It was then pro- posed that a piece of silk should be added to the gold- beaters skin, to which I did not object, till, on enquiry, I found that the silk Miss M'Avoy used was in Dr. Renwick's 2)os.session : I then refused to have any other." What Mr. Sandar's meant to infer from this * Each of the modes adopted have been tried upon other individuals, and have for the most part effectually blindfolded them, and more particularly, if their features were similar to those of Miss M'Avoy. If her opponents will not believe a fact which is notorious, because it does not coincide with their own opinion, it will be of little avail to reason with them ; but it must plainly ap- pear to every unbiassed mind, that their obstinacy upon this point, has been carried so far,as to reach the border of absurdity ; for what can be more absurd, than to say a person cannot be blindfolded by the different means I have cm- ployed ? ! ! ! 148 paragraph, I cannot exactly point out, but it is proba- bly that sort of insinuation which a man, who argues from weak premises, but who is anxious to obtain his point, will sometimes hazard, even at the expence of his credit. I must imagine it had some reference to his suspicion of imposition against Miss M*Avoy and her friends, for he must be well aware no charge of this kind could attach to me, and it would have been better had he abstained from such remarks. Mr. S. avails himself of any typographical or other errors, which a few of the first copies of the Narrative contained, and he sonietimes plays upon my words in a very amusing manner, although he afterwards confesses he understood my meaning by explaining it. " Vague- ness of assertion, he says, and impatience of scrutiny characterize the whole conduct of unbelievers." If this were not the mere parade of self consequence, and of a>sertion, it might be retorted with more truth, upon at least one of the unbelievers, as I am obliged to call them, for on the 24th of September, Mr. Sandars's scrutiny was not received as a proof of his patience, and vagueness of assertion, might with more propriety have been supposed on his part. Mr. S. should have taken the Rev. Thomas Glover's word, when he says, " having completely blindfolded her," at least if he did not do so, he should have hesitated about covering one of his own eyes with the gold-beaters skin, and the other voith his hand only, as an experi- mental test. Dr. Jardine, allows he said the test was imperfect, if the eyes were covered with only one piece of gold bea- ters skin and silk or crape ; but when the goldbeaters 149 skin and velvet were applied over the first covering, he could have no doubt that the eyes of Miss M*Avoy were blindfolded. If applied properly, and a little time allowed for them to dry upon the closed eye-lids, as I have said before, either one or two fresh pieces of gold* beaters skin, will be equally sufficient. In page 31, Mr. Sandars takes an opportunity of say- ing that " from the omission of particulars so important when he was present, it was natural to conclude that there might be others of considerable consequence ; and having heard a detail of the experiments at Wavertree, somewhat different from that given by Dr. Renwick, I applied to Dr. Trail, who had been present." Mr. San- dars, in this, as well as in many other instances, appears to wish to impeach my evidence, but such an attempt will not avail him with the public. In the Narrative, page 23, I have observed, " Dr. Jardine took notes of the ex- periments upon this occaibservatiou, when I have met him in the street, I never thought his sight very acute, and at the distance he was 171 placed from this female, I scarcely thinJc he would be justified in swearing so positively to her person, and still less so to her complexion. In height, she is about the 8th of an inch taller than Miss M'Avoy ; the difference of bulk was so trifling, it would be hardly discernible. I state these circumstances more positively, because I was induced, from Mr Turmeau's account, to measure the height of the parties in the presence of Dr. Hannay and of Mr. Thomas. A little variation might arise, from the circumstance of Miss M'Avoy being supported, on each side, when she was measured, as she was unable to stand upright, but I think, could she have stood up, she would have been fully as tall as Mrs. Norris. Mr. Turmeau mentions as a further proof of his accuracy, that he could, if he thought proper, give the name of a lady, who declares she heard Mrs. Hughes bid her daugh- ter go into the kitchen and take care of the child ; and she went accordingly. Soon after this, he says, he saw her in the passage. I am assured, also, that Miss, M'Avoy never had the child in her arms during that day, for in the early part of it, she was engaged in getting up her own linen, and afterwards she was too unwell to hold it. Considering the agitation of Miss M'Avoy, it is not very likely her mother should desire her to go into the kitchen, nor up stairs, as was mentioned in the first place, as there was no fire in the kitchep, noc a chair up stairs to sit down upon, the house belonging to Mrs. Hughes, and not being te- nanted at this time What Mr. Turmeau's motives were for not informing Mr. Dale of his previous acquaintance with Miss p. he does not explain, although he says the parties discovered this aftervvards, as yoy will observe in the Sequel ?'* * What this Sequel was, does not appear in the letter published in the Li- verpool Mercury. — Vide this letter in the Appendix. 172 The Seond Letter is from an anonymous person, and Mr. Sandars says ** it is presumed that this gentleman's testimony proves she has not a very exquisite touch. — ■ From the error committed in reading the line, a very strong presumption arises that she got it by rote, pre^ viously to covering her head, and that her memory hetrat/ed her.'' The gentleman does not say the book was open before her previously to her head being co- vered ; but in the beginning of his letter he says the goggles were applied. 1 must of course, suppose they were applied properly, and I think Mr. Sandars prema- ture in making these remarks. He commits himself, when he s^ys, " h^r memory betrayed her," because when she named a few out of several pieces of coloured glass, at Wavertree, he gave her credit for an excellent memory ; but now it appears to suit his purpose better to say she is deficient in memory. Would it not have been more candid to have supposed she might have read the line wrong, as a person who had good sight, but who read hastily? If she really did see, it is not likely she would make the mistake that thisaiionymcfus writer might expose her. "A piece of crimson and white paper was put into her hand, with the coloured side down, after feeling at it for some time, she decided it was black and white. On afterwards holding the paper up to the light, the crimson colour }iad very much the appearance of being black. "=^ The failure in the third experiment may be accounted for by the sudden evanescence of the power, and her » This is a curious circumstance, and it puts me in mind of Mr. Hughes, formerly a pupil of our Infirmary, but now upon the Madras establishmer\tj having remarked that she said a dark blue silk was black, and when he held it up to the light, it ?ippe?ir?d quite black. At another time she also named yellow to be a component part of a gown, which was ;iot known to have any particle of yellow in it, nor could the party to whom it belonged, believe it, \intil the gown was ript and the yeIlo\y shreds drawn out, Ho\y are these cir- cumstances to be explained ? 175 success, after the paper was withdrawn, to its return. At any rate the cunning sometimes attributed to her, was not very conspicuous in declaring it so immediately after the paper was withdrawn. The fourth experiment can only be explained upon a similar principle with the third ; and although the letters on "the seal were sufficiently large for a person with any delicacy of touch, to have told what they were, yet this writer might have supposed that the same causes which produce the evanescence of the power, might have acted in this instance totally to incapacitate her from naming even a letter, which might be easily felt by another. The third letter is from Mr. J. T. Koster, which re- lates to an examination which took place on the after- noon of the 23d of September. I was present, and have remarked in the Narrative, that the experiments made on that day were generally successful, and the parties thought the coverings sufficient for the purpose of blind- folding her. The coverings were two pieces of gold^ beaters skin, the first sewed upon fine crape, and the se- cond upon velvet, which were applied in rotation, after the eye-lid had been properly closed, having been wetted in the usual manner, and held upon the eyes until they were dry. Mr. Koster insinuates, from her naming the co^ lour of Mr. Earle's hair, after Miss M'Avoy returned in- to the room, which she could not do before she left it, that it was owing to his head being placed within the line of vision, and that the intermitting of what is called the young lady's faculty, together with the alleged necessity of a free communication between her breath and the object to be distinguished by the touch, are extremely convenient." Mr. Koster may be correct, when he states that the hat Miss M'Avoy first put her hand into, be- 174 longed to Mr. Earle, but I did not observe it. I recol- lect, however, Mr. Wm. Earle 's hat was presented to her, which in consequence of his wearing powder, was so soiled that I returned it to him, as Miss M'Avoy had more difficulty in distinguishing colours, reading, &c. where any greasy substance intervened. Whilst giving Mr. William Earle his hat, a gentleman presented hjs own (a new one) turned up-side-down, and she read the makers name, but could not make out the German text which followed. This might probably have escaped Mr. Roster's notice, or he would certainly have mentioned it.-'^ There is nothing else very material in this letter, as what Mr. Koster has noticed, is very similar to that I have stated to have occurred at different periods. The fourth letter is that of Mr. Worthington. I was not present at this examination, but Dr. Jardine informs me it was his opinion the goggles were not tied on properly. From the appearance of Mr. Wor- thington's face I have no doubt they would have blind- folded him completely ; at least all who have tried them, with similar faces, allow them to have done so. Mr. Thomas also informs me, she was very much agitated during a great part of this examination, so that her pulse beat at the rate of 160 pulsations in the minute, and that when the paste board was used, she was surrounded with lookers on, and one gentleman placed himself very near^ and immediately opposite to her face, so that it would de- prive her of the power, by producing that peculiar op- pression any near obstruction to the breath almost imme^ diately occasioned. Most of the other circumstances iu • Mr. Thos. Myers, the Editor of the Mercantile Advertiser, who was pre- sent on this day, perfectly recollects this experiment having been made, an<^ its success. 175 Mr. Worthington's letter have been so often mentioned in the Narrative, that it is unnecessary to dweli upon them. In this letter is also noticed, the previous direction of the eyes with a rapid and instantaneous glance at the ob- ject, and when they were not directed to it, she did not name the colour, Mr. Worthington acknowledges the eye did not blink when he rapidly darted his finger to- wards the eye* He allows also that the pupils contracted as much as those in healthy eyes, but he thought rather more slowly, I have been informed at the time, Sir G. R. Collier left the house, he expressed himself generally satisfied with the result of the experiments; but afterwards it has been said, he altered his sentiments, although he did not visit her again. A number of stories have been propagated at this gentleman's expense, by one of those individuals who derive their support from the publication of the miseries and wickedness of their fellow- creatures^ terminating with their last dying speech and confession. But as these are often prepared for the purpose, without any certain foundation of their truth, so I presume has this gentleman's name been brought in for a similar end, the profit of the printer, or publisher, or of both. The fifth letter is that of the friend of Mr. Bradbury, and the facts contained therein, have been stated by Mr. Bradbury, in the presence of Mr. Egerton Smith, Mr. Bywater, and Mr. Rushton, the late partners of Mr. E. Smith. The public must judge of this letter, and I should wish the numerous individuals who have witnessed Miss M'Avoy's powers, would declare their sentiments of it. lam confident the great majority of them will say they never saw her attempt to do any thing of a similar nature. That Miss M*Avoy might occasionally appear to look towards the object, she described, is very probable, and T,ery natural ; but that she drew the cloth from behind 176 Ber back, rapidly glance at these gentlemen, gaze at the cloth, restore it to its former situation, before she named it> "credat Judaeus Apelles non ego."*^ Is this gentleman not aware that expefimerits had been made in the presence of very many respectable witnesseSj with the most satisfactory result, when the eyes were co- vered, as well as iincovered. Am I, or are these witnesses to giv^e up our united opinions, formed upon repeated examination, to Mr. Bradbury's positive assei'tion unsup- ported by any other evidence ? Satisfied as I and other persons, capable of judging, are, of Miss M'Avoy's com- plete blindness, what must we think of Mr. Bradbury, who evidently visited her under extreme prejudice ? The sixth letter is that of Mr. Lutwyche. It appears to be artfully drawn up, but a few comments upon it will shew how far it is entitled to the consideration Mr. San- dars and others have given to it. I shall notice the most prominent parts. It is somewhat curious that Mr. Lut- wyche never publicly stated the result of experiments made in February, 1817, upon a subject of this importance, until called upon, by Mr. Sandars, because, if Mr. Lut- wyche believed in his own experiments, he was doing in- justice to himself in not detailing them before, and to me also, if I relied on their verity, as it would have prevent- ed me from troubling the public, with a perusal of the Narrative, and would have saved me a good deal of la- bour and of expense. The story of the Valentine ap- pears improbable to me, who have so often seen her trace different figures upon calico, silk, paper, snuff boxes, • Mr. Jones has slated a similar circumstance with the lilac handkerchief, and this assertion would appear as tlie prototype of Mr. Bradbury's, or vice versa. r 177 (fee* ; and who never yet heard her name a figure until her fingers had passed over it. So many evidences might be brought forward to prove this point, that I think it totalJy unnecessary to make any further com- ment upon i(. How far Mr. Steel's instrument,, made of pasteboard, would answer the purpose of interrupting sight, and yet admitting the communication of the fingers with the mouth, the public will judge, when they read the para- graph in Mr. Lutwyche's letter, containing an account of it; for it certainly appears to me rather to prevent the breath from communicating with the fingers; but as further experiments have proved the opinion of Miss M*Avoy, respecting the influence of the breath, in the distinction of colours, &c. to be erroneous, it will not be necessary to dwell upon this part of the subject. The account of the watches offers the strongest obstacle to the veracity of Miss M'Avoy; but I fear the eagerness with which these gentlemen have attempted to prove Miss M*Avoy an impostor, has been the cause of making them the dupes of each other. Mr. Lutwyche certainly does not rely on the force of his own experiment, or he would never have wished for a second interview ; of course, holding the opinion I do, of Miss M'Avoy's blind- ness, I should suppose this letter was manufactured for the purpose of misleading the public. The story of the handkerchief rests upon mere supposition; but that of the shreds of silk is a master-stroke ! Whoever saw her literally tear the silk, but Mr. Lutwyche and his friends? Hundreds, I may say thousands, have heard her name colours she had felt, but not one, except this gentleman, and his friends, ever saw her rub the silks so as literally to tear them, or to " handle them with a roughness, which z 178 would rather tend to ascertain if they were hard or soft, than to receive the rays of light and colour," All who have seen Miss M*Avoy distinguish colours, will be con- vinced that this is a forced account, and not worthy of belief; and yet this " trifling circumstance which must not be passed unnoticed, and which tended more than any other circumstance, to shake our faith," Mr. Lut- wyche says, " and to rank us among the unbelievers," could not be comparable in any degree, as a proof, to the very positive assertion that she told the time of the day in one watch, which it was supposed she had seen, instead of the watch, which he professed to place in her hands, but which had been exchanged in transilu. Could there have been a comparison between the two facts, as stated in Mr. Lutwyche's letter ? In relating the tale of the shreds and severe rubbing of the silk Mr. Lutwyche has overreached himself, and by endeavouring to prove too much, has proved nothing. Nay, he could not get over the fact of her telling the colours behind her, without the aid of the shreds, and the severe rubbing compleated the climax! I might indeed, ask Mr. Lutwyche, how Miss M*Avoy managed from the want of this aid, when the silks were inclosed in glass?* In the MercAiry of Nov. 14, 1817, is a letter of Mr. Egerton Smith, addressed to iT.e, wherein he quotes 6ome observations with which I prefaced the introduc" tion of his letter in the Narrative, as tending to impress upon the public mind, that there was a discrepance be- ♦ Mr. Sandars has given some particulars of the circumstances whicli occur- red on the 13th of September, 1817, which are merely hinted at in the last page of the Narrative. My account of the examination on that day, will probably be found more accurate. Seepages five and six of the continuation of the Case, and compare it with the account of the particulars related in the Hints toCre* dulity, pages 36 and 37 ; or in the Appendix to the continuation of Miss M'Avoy's Case. See the letters in the appendix. 179 tweeu his testimony and his convictions. However justly I might have done so, I had no intention of mak- ing- any charge against Mr. Smith, but what was inevi- table Irom his request that 1 would insert his letter in the appendix, as it was necessary for me to assign a reason for introducing it there, when I had before made the requisite quotations from it. Mr. Smith, by the pub- lication of his letters and paragraphs in his paper, had fairly laid himself open to the investigation of them, and as the narrator of this case of Miss M*Avoy, 1 had an undoubted right to make those extracts from them which had a relation to the subject, and to give them as evidence at the bar of the public, who were capable' of appreciating their value. Whatever Mr. Smith's sentiments were at the time of his visiting Miss M'Avoy ; whatever they have been since ; or whether he has been influenced or not by the opinions of other persons, is of little consequence, but he must certainly allow me to judge of the result of his experiments ; and that judgment coolly and dispassion- ately exercised, prevents me from retracting the opinion 1 had before formed, that they afforded very strong evi- dence in favour of Miss M'Avoy. Mr. Smith says he con- fined him>elf to the scrupulous relation of facts, that he saw her decipher very minute print and other objects, in a light wherein he could barely discern the leaves of a book. With a bandage over her eyes, through which, when applied to his own, he could not ascertain the dif- ference between moon and midnight, he saw the young lady determine accurately the colour of cloth, riband, glass, and other substances : and also peruse writing and printed books. All these unaccountable facts he saw with astonishment, and recorded with fidelity : but it cer- tainly does not follow, because he could not corapre- 180 hend how they were in reality effected, he must neces- sarily believe they were the result of touch. He is a little at a loss to discover how I could either by implication, or more directly press into the already crowed ranks of the believers, a person, who in the very letter to which I had referred for my proofs, had ex- pressed himself in the following heterodox style : — " 1 could not account for what I had seen, except on the supposition that Miss M'Avoy was not blind ; but had some secret mode of discerning an object." And again, " T never could divest myself of the impression, that the eye was in some way or other concerned in these mys- teries." Mr. Smith leaves it to my ingenuity to explain how such an unequivocally expressed distrust of the fa- culty ascribed to Miss M*Avoy, can have more weight with the public in persuading them into a belief of the same faculty, than his bare assertion of his doubts found- ed, as I presumed, upon the opinion of those individuals. I gave in proof of Miss M'Avoy's very peculiar powers, these very experiments, and nothing has been advanced by Mr. Smith, but mere supposition to contradict them. The opinion of other persons, Mr. Smith allows, had no small share in confirming the suspicions he uniformlij entertained after his first or second visit. So far he therefore assents to the correctness of my thoughts upon the subject ; and many persons who have read his detail of these ei^periments consider them, as I have done, and do not hesitate to say he has committed himself, by yielding to these opljiions, against the evidence of his own observations: for what proof has Mr. Smith given that Miss M'Avoy has such very acute sight, supposing she really could see, as to know the colour of objects, to read words, &c. in a light where he could barely discern the leaves of a book ? 181 Mr. Smith, indeed, in another part of one of his papers, (T/«? Mercury) endeavours to qualify his sentiments af- terwards, by graduating: the si^ht of different individuals, and he wishes to diminish his own power in this respect, while he increases that of other persons ; and at last his defence of himself becomes so weak as to oblige him to call to his aid the surprising stories of VVanley, and the wonders of Munchausen. Mr. Smith, as well as all her other oppo- nents, would have been at a loss for arguments, if it had not been for the mistaken opinion of Miss M'Avoy, re- specting the influence of her breath ; but as they have no better ground from which they can make their attack, they are determined to maintain it as long as they can. I shall give them all the advantage of the error, but the foundation has been sapped, and it will soon be untenable even by the most hardy veterans in their opposition against Miss M'Avoy's pretensions. However preposterous it may appear to Mr. Smith, it is nevertheless true, that " with her hands behind her, upon the window opposite the communion end of St. Paul's Church, she told the Bgures of people passing, and the colour of the clothes, &c." It is no less true that she named a purple flower, behind her, a light yel- low, a marygold, and a small pincitshion of red cloth, under a white handkerchief laying upon her knee, when her hand was introduced under the handkerchief." — Mr. Richard Rathbone, Mr. Barclay, their Ladies, Miss Reynolds of Coalbrooke Dale, and other persons were present when this experiment was made ; but this was not more surprising than her declaring the colour of one of the Claude Lorraine glasses, which Mr. Smith, Mr. Nicol, and others could not distinguish, until they held it between their eyes and the sun, when Miss M'Avoy's as- sertion was confirmed. 182 On the 12th of September, 1817, Dr. Taylor, late of Bolton, was present with another gentleman, the Rev. John Yates and his daughters, and the Rev. Thomas Belsham. I have said upon this examination, her pow- ers were deficient, although she named several coloured silks correctly. She read very uncertainly a few words, and told the time of the day in a watch, and she named again the time of the day in two other watches, which were not exactly alike. • Mr. Smith does me but justice, in supposing I would not wilfully suppress any fact which might militate against my theory, as he expresses it; but Mr. Smith ought to know the statement in the Narrative originated from the facts which occurred at the time, not from a bias on my part to any particular theory. He mentions Dr. Taylor having pushed a stick towards Miss M'Avoy, but 1 did not observe, although I recollect the circum- stance, with what intention he did it, nor did I know the deduction he drew from it, until I perused Mr. Smith's letter. I must own I do not very well comprehend it now, thirty-two months after the occurrence took place. It seems an extraordinary circumstance Miss M'Avoy should attempt to discover and actually name the nature of the metal upon the upper end of a cane, when the ferule was presented to her ! It would give me no proof of her discernment, very little of her cunning, and still less of her power of touch, to suppose for one moment she did not know the difference between the ferule of a cane and the top of it. As one proof, however, that the examina- tion of this day did not produce a similar effect upon the rest of the party, as it did upon Dr. Taylor, 1 shall quote a part of a passage taken from the Medical and Physical Journal for Nov 1817, which must allude to this exami- nation. It is as follows, " satisfactory as the Rev. Mr, 183 Glover's account of Miss M*Avoy must be to all impar- tial readers, it (?annot be amiss to add that it has been confirmed by a conv^ersation with another Reverend Gentleman, long and well known for his Philosophical acquirements, the steadiness of his judgment, and his correct method of conducting his experiments." If I am rightly informed, this gentleman was the Rev. Thomas Belsham, who, I believe, was present only on this day. The tale of Mr. Bradbury, as well as the observations of Mr. Lutwyche and his friends, I have already commented upon. I must candidly confess there is as little reason for supposing Miss M'Avoy to labour under the hallucina- tion of imaginary blindness ashy any comments, explana- tion, or ridicule to do away with the force of Mr. Smitii's own experiments. Peregrinator, to whom Mr Smith alludes as the person propagating this opinion, has adduced some other notions in a positive manner. He says, " I do not believe that she is blind ; indeed, I may say it is demon- strable she is not blind ; for in the present state of her eyes, it is as impossible that she should not see, as that a room with open vi^indows should be dark in the day time. There is no outward apearance in the eye,' of opacity of the cornea, or of the disease of the chrystaline called cata- ract; and the eifect of an increase or diminution of light in producing a contraction and dilatation of the pupil, will convince any one at all acquainted with physiology, that she is not affected with " gutta serena," or, in other words, that the optic nerve has not lost its sensibility. I am surprised that this latter circumstance has not had more weight with Mr, Glover and the other scientific men, who have paid attention to Miss M'Avoy's case. I have 'yet to learn upon what principle this contraction and dilata- tion takes place, unless it be from sympathy between the iris and the retina; by this means, then, if I be not incor- rect, we have the power of deciding beyond dispute, that 184 jn Miss M'Avoy'scase the optic nerve is sensible to lig^ht, in some degree at least, and as she does not acknowledge this in any degree, it is certain either that she wishes to impose on the public, or that she is imposing on herself." Had this writer examined attentively Miss M'Avoy's eyes he would have paused before he made the above ob- servation; and if he had seen many eyes afflicted with gutta Serena, he would have known that contraction and dilatation did sometimes occur in these cases, but were not esteemed by physiologists as a Certain proof of vision. The wager Mr. Smith offered to bet, of twenty guineas, with the different additions made to it since, he must hav^e been well aware, could not have been accepted, because Miss M'Avoy's health, at the time, prevented the trial of any experiments which might distress her, from the ob- struction given to her breath; and the repetition of the offer should have been avoided as it could not produce any satisfactory proof against her, even if it had been tried. This offer has been very often alluded to by the oppo- nents of Miss M'Avoy's powers, and her non-acceptance of it has been brought against her. The very appearance of this mask, of which there is a print in the Mercury , will convince any one, who has seen the effect a hand placed before the mouth had upon Miss M'Avoy, that it would produce those sensations so distressing to her, and deprive her of the power. The following paragraph, taken from the Mercury, will show the temper of some of her opponents — "In re- ply to a very general verbal inquiry whether any notice had been taken of the proposal, we have only to state that in our absence from the office, a gentleman called to say that Miss M'Avoy would accept the challenge, provided she might have the mask in her posses- sion for a few days previous to the decision ; as we do 185 fwt know the individual who made this extraordinary proposal, was authorized hy the Lady or her friends, to deliver such a message, we shall abstain Jrom any comment for the present'' Mr. Smith goes on to pro- pose that two masks shall be provided, exactly similar ; one of which shall be kept with her as long as she pleases, on the condition that she shall exhibit in the other. The Editor of a Newspaper allows himself great latitude ; he can assume his own form or that of another person, in making any assertion which may suit his interest, or gra- tify his spleen, but I must own I gave Mri Smith credit for better feelings, than to suppose he would condescend to make his paper the vehicle of assertions so insulting to an oppressed female. He must be well aware no gentle- man ever went from Miss M'Avoy to offer such a propo- sal, and his attempt to foist such an opinion upon the public, will be received with the regard it merits. Mr. Smith informs us, that the public is already in pos- session of the ingenious device of Sir George B.Collierj who is said td have practised such whimsical grimaces and distortions of countenance, face to face with the lady, that she could not resist the effect, but fell into a most immoderate fit of laughter I Is this information derived from Sir George B. Collier, or does it originate with Mr. Bradbury's friend, or with the publisher of certain memorable events, who may have made Mr. Smith the vehicle of conveying these malignant aspersions? I have asked several persons who were present at this examination if this account were true ; but it seems they had not observed any of these grimaces Sir George B. Collier had the merit of making. Mr. Smith says, " we have also heard from a very respecta- ble and not very circuitous quarter, that our heroine has been seen repeatedly dressing her hair, and adjusting h(Pr A a 186 dress in the ordinary mannerof a young lady at her look- ing glass." I merely ask Mr. Smith for his proofs upon this point, and he surely will not hesitate to give up his authority for this assertion.^ I am not aware who is the author of Veritas, who ad- vocates the cause of Miss M'Avoy ; but I do not agree in Mr. Smith's remark to " audeamus alteram," when he says, that our notions of candour and justice do not ex- actly square with his, nor can he reasonably expect we should insert the letters of Veritas, upon this subject, " when they have already been published in the Liver- pool Courier.'^ The letters of Veritas differed from the present opinions of Mr. Smith, and tha opponents of Miss M'Avoy ; but if I mistake not, Mr. Smith had pledged himself to publish the arguments on both sides of the question ; and it would only have been fair, if he had published the letters of Veritas. His politeness to the Courier, the opponent of his political and other opinions, upon this occasion, is not a little suspicious, but I have no doubt the Editor of that paper, will properly appre- ciate his forbearance, in not publishing what has before appeared in the Courier. Mr. Smith, does indeed, ex- • During the period when this assertion must have been made, it is well known Miss M'Avoy had no hair to dress, from her head having been so repeatedly shaved for the application of blisters ; nor am I aware she ever had recourse to the use of false curls for the purpose of adornment. I must there- fore set this assertion down as one amongst many others, which have been dressed up for the purpose of throwing more obloquy upon this injured female. Many other circumstances have been mentioned in that manner, which would produce an effect upon minds which are liberal and good, to the disadvantage of Miss M'Avoy ; but when they are duly considered and explained, they will be found to,have had no other foundation than in the imagination of the indi- viduals who propagated them, or from that miserable propensity which sortie persons have of examining at their own partial bar, the conduct and character of their neighbours. 1S7 cuse himself for dwelling more upon the facts adduced by the Anti-M'Avites, because he conscientiously 6e- lieves the truth to he on their side I The Writer who signs himself with a hand cut off at the wrist, in the Mercury, and who is said to be Mr. Smith, produces objections against the plain and simple statement of two ladies, whose habits of rigid veracity, and cautious inquiry, are well known ; and whose names were left with the publisher of the Saturday's Adver- tiser.^ I have inserted a copy of this, among the other letters. This writer doubts the accuracy of these ladies, and attempts to apologise for the rudeness of his doubts by saying • «' When alady*s in the case, t* All other things of course give place." Thii public will judge of this letter, and as it comes from persons unconnected with Miss M'Avoy, it may have that weight which the above writer denies it. The ex- periment has often failed, but it has frequently succeed- ed. The eye-lids of Miss M'Avoy were sometimes very tender, and if pressed roughly, she suffered so much pain, that it deprived her of the power. It has been cus- tomary for the opponents of Miss M'Avoy to propose tests, and when they have succeeded, to object to them ; so it has been in this ease, and we find this writer prefer- ing the application of the whites of eggs, gold-beaters skin, as more compleat, than the application of the fingers to the eye-lids, and less liable to the alleged objection. I have now given a general and rather elaborate account of the proofs adduced by Mr. Sandars and others, and the public will be better able to judge how •See the letter signed T. S. M. in the appendix. IBS far the basis, upon which the opponents of Miss M'Avoy have endeavoured to arraign her integrity, is well founded and correct ; and whether the motives which have actuated them in the prosecution of this subject have been pure, not tinctured by prejudice, not biased by any other motive than the simple elucidation of the truth. OF MISS m^avoy's case X SHALL give a general account of the powers of Miss IVrAvoy, and recapitulate the principal facts in the Nar- rative ; the names of several of the witnesses who ob- served them ; the experiments of Mr. Egerton Smith ; of the Rev. Thos. and Edw Glover, and of a few other in- dividuals, which are corroborative of those I have stated. . On the 28th of June, 1816, when Miss M'Avoy reco- vered, in some measure, the use of the ri^ht hand and arm, Mrs. Hughes gave her a stocking to knit, which oc- cupied her attention and relieved her from that total want of employment her illness occasioned, On the 2d of August, I was induced to call upon Miss M'Avoy with Mr. Thomas, who told me she had become very expert in sewing. I found her in the act of sewing, which she appeared to execute with considerable neat- ness. She put into my hands a stole, which she had as- sisted in finishing for the Rev. Edward Glover, her con- fessor, to whom she was under very considerable obliga- tions for his kindness and attention during her illness. She also made several neckerchiefs, and a frock for her 190 little sister, and darned a pair of black silk gloves with great neatness. It appeared from the account of her mo- ther, Mrs. Hughes, that before Miss M*Avoy was able to leave her bed after the first attack, she complained of weariness and anxiety, particularly in the night, which, from not sleeping well, appeared long and dull. Miss M'Avoy requested her mother to give her a needle, that she might try to thread it. The first time she made four attempts before she succeeded in threading it, and the se- cond time she threaded the needle after two trials. She then asked for sewing, and her mother gave her a coarse towel. She was very awkward at first, and this awkward- ness was much increased by not looking at her work, and her eyes seemed to be wandering in every direction, about the room, but where they ought to be. Her mo- ther desired her to fix her eyes as if she were looking intently at her work. Miss M^Avoy endeavoured to follow this advice, and applied with so much perseve- rance, that she succeeded nol only in this point, but sewed much better than ever she had done before her deprivation of sight.* Mr. Thomas and I particularly • After the Wavertree meeting, the doubts expressed of her poAvers, pro- duced an unexpected effect upon her general system. If she were asked to sew, particularly if strangers -were present, she would attempt it, but was of- ten obliged to lay down her work, as if incapable of proceeding with it. If no notice were taken of her, she would resume it, and go on sewing ; often with her eyes directed in such a manner that she could not see the work, if her vi- sion were perfect. When the catching or oppression in the breathing, or the convulsive motion of the diaphragm comes on, she is frequently observed to de- sist from sewing, and knitting : and will often not be able to resume her em- ployment for a whole day, or even for a longer period. It would appear, there- fore, t hat the liending down of her head upon her v>ork, is the mere effect of habit, and the occasional incapability of pi-oceeding with it, must arise from that nervous irritability excited by the slightest cause, and which is the most peculiar concomitant of her case. This supposition is moreover, confirmed by the quality of the work ; that which has been done while these symptoms were more moderate, or absent, being extremely well executed, whilst the other parts Will be better or worse done, in some proportion to the degree of violence with I9l examined her eyes, exposed to the light of a candle, as near to the eye as possible without burning her, but without observing the slightest contraction or dilatation of the pupil, or the least sensibility in the eye. I have frequently, since this period, thrown my hand suddenly towards her face; have pretended to dash a pointed penknife at the eye ; and have often applied the point of the finger in a quiet and steady manner, as near as possi- ble to the pupil, without observing the slightest sensa- tion in the eye. Mr. Thomas assured me he has more than once put his finger upon the cornea itself, which then appeared insensible; but when he touched the eye- lid or eye-lash, she was instantly sensible of it. I have sat for a considerable time attending to her sewing, but apparently indifferent about it ; and during: these visits, I have examined her every action as minutely as possi- ble, and- 1 have been satisfied she could not see. In threading her needle, it sometimes required only one ef- fort, but often three or four, before she was successful. It was curious to observe her when, by accident, the point of the thread was bent: she would try to thread the nee- dle three or four times, and if she did not succeed, would put it into her moulh, and bite ofP a part, or take her fin- ger and feel whether the thread were straight or not. More than once I have giv^en her the needle with the point upwards, when she accidentally dropped it: she attempted, but finding, after a few trials, that she could not thread it, she would put her finger upon the needle, and feeling the point, would turn and thread it: once, also, I broke the eye of a needle iu drawing the thread which they affect her. This I proved in the dark one evening. I gave her a cravat to hem, which 1 had marked for the purpose. She threaded her own needle. The first part, which she hemmed, was very well done, but tlie latter very indifferently, asthe catching in the breathing cairip on duriua: ihe limi^ with considerable \ iolence. 192 hastily out; but was not aware of the circumstance until Miss M'Avoy had made several attempts to thread it ; but failing, she felt the eye with her finger, and told me it was broken, which, upon examination, I found to be the case. In the general business of the house, she was more active than ever she had been, assisting in making the beds, attending upon her half brothers and sisters, and was cheerful and agreeable in her manners to every body about her, and more particularly to those who visited at the house. I shall now give an account of the manner in which it is stated Miss M*Avoy found herself possessed of cer- tain powers of an extraordinary nature, and the relation of which excited the curiosity as well as the criticism of many individuals. It was very early in Sept. 1816, that her stepfather, Mr. Hughes, was reading a few pages in a small book belonging to one of his children, in which a history was given of the life of St. Thomas a Becket, nol very favourable to his general character. He men- tioned it to his wife and daughter, and said he recollect- ed having read once a very different account in another book. Miss M'Avoy told him she had, before she was taken ill, seen an account of his life in a book enti- tled the Lives of the Saints, and, if she had the book, could point out the place where it was. The book was put into her hands, and, in turning over the leaves, she pointed out the place, passed her fingers over it, and read a few words. In a jocular manner Mrs. Hughes asked her if she could feel the letters with her fingers. -She said she felt the words she had read, and would try again if her father would give her a book. A number of a folio bible, of tolerably large print, was given, and she 193 read several verses to the great astonishmeDt of her fa- ther and mother. Upon hearing this account, I was in- duced to visit her again with Mr. Thomas, and took con- siderable pains in examining the eyes ; but we found little or no alteration in their general appearance, except that the pupil was not quite so much dilated as before ; but the light of a candle appeared to have no influence upon it. We found her father's account very accurate, and that she really could read by the application of the fin- ger to the letters, with considerable fluency- As it was probable any other person, who had not the same oppor- tunity of judging of her blindness with Mr. Thomas and me, might think it possible she could see, I thought it right to bind something over the eyes, and I made use of a Manchester cotton shawl, which went twice round the head, crossed the eyes, and was tied at the back of the head, as firmly as she could bear it. I placed in her hand a number of the Bible above mentioned, and she read v^ery correctly one verse of a chapter in Genesis. I then re- quested to have another book, which happened to be a volume of the Annals of the Church. I opened it, and she read to me several lines, with the alteration in a pro- per name of only one letter, which, upon being desired to read over again, she corrected. I then turned to a few lines of errata, and she read them correctly, only read- ing the letter 1. as an I and a dot. The mode she follows is to place her fingers upon the book, and when she feels the letters, to proc^d from the beginning to the extre- mity of the word, and back again until she names it, and so on to the next word. She often makes use of the fin- gers of both hands, particular the fore fingers ; and when they are in good order, she will read from twenty-five to thirty words in half a minute. On the following day I mentioned the circumstance to Bb J94 a friend, who was anxious to see a phenomenon of this kind, and he met me in St. Paul's Square. MissM'Avoy again read over to us a verse in the Bible, a few lines in the Annals of the Church, and the title page, mottos, and several lines in a 12mo edition of Grahame's Sabbath. I placed her fingers upon a blank leaf, and desired her to read. The attempt was made, but she said she could not feel any letters. Her fingers were then placed upon another leaf, which she declared was also blank. 1 then desired her to feel the upper part of the leaf; she did so, and said she felt something, but it was so confused she could not make out what it was. The fact was, a lady's name had been written in the book, and when 1 took it from my library, I scratched the name out with a pen, so that it was not distinguishable to the eye. My friend brought with him a French assignat, of which it is more than probable Miss M'Avoy before did not even know the name. She read it over, and mentioned the lines upon it as distinct from the plain paper, and the colour of them, which was black : she also decyphered the ad- dress and post-mark of a letter received by that morning's post : she named the colours of the coats, waistcoats, and pantaloons of the gentlemen present with accuracy. She gave a correct account of a few cards, one or two of which were put under a small table, placed before her. A little boy, the half-brother of Miss M'Avoy, brought in several pieces of broken glass, of different coloursi She told very readily the different colours as they were ^iven to her, and, in a few pieces, where the glass had not been perfectly fused, she named the colour of that part which was perfect, and of that which was imper- fect. She distinguished the different colours of silk, of cot- ton, i}T of wool, and the brighter and more vivid the co- 195 lour, so much greater is the pleasurable sensation it af- fords. If they consist of many colours in the same piece, she will point out each colour, and trace the line where it terminates. If the silks are of that kind called shot silks, she will tell the colour of the ground, as well as the intermixture. If the different pieces are besmeared with oil, or any greasy substance, she cannot so easily distin- guish the colour; but if it be nearly faded, she will point out where it is faded or where it is bright. She can dis- tinguish the colours of the paintingsof enamelled or var- nished boxes, will trace the outline of the figures, and will generally state the subject of the painting with a de- gree of accuracy which is surprising. At times, how- ever, this feeling is suddenly lost, and after describing colours, reading, &c. with great nicety, she will declare she cannot tell the colour, or will say it is black. The persons who have visited her once, are generally knovi'n to her again by their manner of walking or breath- ing, or by the voice. She tells the dilTerence in the size of one person from another who enters the room, if asked to do so. If a colour be placed upon the back of her hand, or upon the cheek, she will name it correctly. She has at different times told colours with her fingers, read with her hands behind her and under the bed- clothes,*^ or under a sheet of paper, but seldom for any length of time. The mode adopted for binding the eyes, in 'the first instance, was the Manchester shawl, and it was generally agreed to be sufficient for the purpose ; but it was not * More than one individual can corroborate these facts. Mr. Evans, Surgeon of Liverpool, was at one time present when she read under the bed-clothes.— vide his letter in the Appendix. 196 tboaght so by a few individuals, and other means were adopted to satisfy them. A pair of goggles were ob- tained, and covered with dark-blue paper. Many trials were made with these, sometimes with, and often without a silk handkerchief tied over them, and over the head. At this period the goggles seemed to be the most in use for covering the eyes, and various additions were made to them, according to the various wishes of the indivi- duals who visited her, until they were made into a com- plete mask, covering the whole of the face except the nostrils and mouth. They were tied by several pieces of tape at the back of the head, in almost every direction, and two pieces of tape crossed each other under the nose, just below where a line of cotton wool was sewed in, so as to prevent any ray of light from passing upwards. Dur- ing the continuance of a severe inflammation of the eyes, which had^been produced probably by the heat occasion- ed by the gogglss, which were kept on for a considerable time, Mr. Thomas and I made use of the pledgets, dip- ped in a weak solution of super acetate of lead, over which a neckcloth was tied, and which answered every purpose we could wish. Occasionally we only pressed the eye- lids gently down with the fingers, and held them in that situation until she had gone through the trial intended. The rumour of Miss M*Avoy's talent in distinguishing colours, soon occasioned a great influx of visitors, wh:o went away generally satisfied she really possessed the power. A considerable number of medical men had alrea- dy visited her, and it became a subject of conversation at Dr. Brandreth's, where a large party dined on the 26th of Oct. 1816. It was agreed that a certain number shoul«l meet me, in St. Paul's Square, on the Monday following, at eleven o'clock, and I sent amessageto Mr. Hughes, stating my intention. I found that, at the re- 197 qu/8st of Mr. Latham, surgeon and apothecary of Wa* vertree, Miss M*Avoy had g-one to spend a few days with his family. A few of the gentlemen put off their inten- tion to another opportunity ; but Drs. Trail and Jardine, Mr. Redmayne,^ and 1, went to Wavertree, and we were very soon followed by Drs. Formby and Vose. Before our arrival, several persons had visited her, and she had been engaged more or less with them since breakfast time. She had named and told colours, and I have understood they were particularly satisfied that jVIiss M'Avoy posses- sed this extraordinary power. Dr. Jardine took the notes upon this occasion, and from the experiments made at Wavertree, however unsatisfac- tory, we may draw the conclusion, that she did not en- tirely fail. At this time the eyes were covered with the goggles, and this mode appearedsatisfactory to the gen- tlemen present. She read a few lines in the Roman History, sometimes correctly, but more frequently she was incor- rect. In a partially darkened room, she made nothing out, except the white lines and letters upon Dr. Trail's varnished snuff box, the white lines of w-hich, Drs. Trail and Jardine could scarcely see. In the third ex- periment, when the eyes were covered with a handker- chief and lint, or goggles and lint, several pieces of glass were given to her, and she told three colours out of four. It should be mentioned however, that she brought these glasses from home, and it may be possibly supposed, she recollected the figures of the pieces of glass, as she had repeatedly fingered them. If this were the case, as the glasses were numerous, her memory must have been very tenacious, to have retained the form. • Mr. Kent is mentioned, in the Narrative, by mistake, as one of the party at Wavertree. 198 and, by the forms, to have told the colour of the glass. In the fourth experiment, the eyes were uncovered, aud she told seven colours out often. If she had been capa- ble of seeing, she might as well have told them all cor- rectly. We ought not, I think, in candour, to attribute this greater degree of power, when the eyes were unco- vered, to her seeing, but to the relief afforded, and to the remission of pain and throbbing in the head, when the pressure from the lint, or cotton, &c. were removed. In the fifth experiment, her eyes were covered with the goggles, stuffed again with lint, and she did not tell any thing. In the sixth and last experiment, the red painted glasses were given to her, when her eyes were unco- vered, and she said the colour was red. Upon the whole, the trial was unfortunate, and it was afterwards cur- rently reported that Miss M*Avoy could see. This dis- appointment was injurious in many respects, not only as it related to the suspicions thrown upon Miss M'Avoy^s veracity ; but as it caused a censure to be cast upon Mr. Thomas, me, and upon many others, in allowing our- selves to be imposed upon, it was still more unfortunate for the investigation of the truth, as it produced a hike warmness in many respectable individuals of our profes- sion, w^hich prevented them from prosecuting the in- quiry.* Mr. Bickersteth, a respectable surgeon, and one of my colleagues at the Infirmary, called upon Miss M'Avoy on the Friday evening previous to the 26th of October 1816. He gave her, when covered, amongst other things, a piece of green silk, striped with one or more yellow lines, and • See my comments upon Mr. Sandars's pamphlet, where he gives an account »f this visit— Pages 31, 32, 33, and 34; and pages 143, 150, and 151 of this con- tinuation of her case. 199 certain figures written upon it; of which Mr. Bickersteth, before he gave it to her, had not taken notice. She said the lines were white, and repeated the number of the figures. On the Saturday following, Mr. Bick- ersteth, mentioned at the Infirmary, the general circumstances which bad occurred. Dr. Gerard, who had formerly been a Physician of that Institution, was present, and it was agreed we should visit Miss M'Avoy at one o'clock. We called upon Mr. Thomas, and pro- ceeded to St. Paul's Square. The eyes of Miss M*Avoy were covered with the goggles, and she told almost eve- ry colour given to her, and read, &c. When, however, the piece of green silk was again put into her hands, she said this is the same piece of silk which was given to me last night ; it then seemed to be green and white lines^ but it is now green and yellow : light yellow, or straw-co- lour, would appear to any one white by candle light, and, it did appear white to Miss M'Avoy.* On the 31st of October, 1816, Miss M'Avoy visited Mr. Charles Clements in Queen-street. There was lit- tle fire in the room, and it was so dark that candles were brought in, but were afterwards ordered away, from the wish they had to hear Miss M'Avoy read, &c. A book just published upon brewing, was put into her hands, and she read a few lines correctly, but in attempting to read the word vat, she only made out a v and a t. Mr. Cle- ments was induced to take the book, and he had some difficulty (from the small quantity of fire in the grate,) to distinguish the words : he, however, found it out to be the letter a, turned upside-down. She told also the co- lours of ditTerent substances, given to her, very accu- ' How may this circumstance be exiilained? 200 rately, in a light by which no other person could distin- guish them, and when the parties were standing between .her and the fire.* At different times, after the examination at Wavertree, Miss M*Avoy continued to distinguish colours, when put into her hand, to sew, read, &c. ; but not with so much certainty as she did at first. She was easily agitated, and, if any one disputed the power she possessed, it al- ways produced irritation, and made her less able to give proofs of it. But with the amendment of Miss M'Avoy's health, the faculty of distinguishing colours, &c. became more acute. On this day, (17th January, 1817,) she not only declared the colour of different cloths, cotton, and silk, but several pieces of silk which w^ere inclosed in a small phial bottle ; she traced with her finger the edge of each ;and, when another phial was given, which did not contain any thing, she declared it to be empty. Bot- tles of white glass, holding magnesia, red precipitate, red oxyd of mercury, and bark, were seperately given to her, and she accurately named the colour, and told how high the bottle was filled with each substance : two small bottles, the one containing water, and the other spirits of wine, were placed in her hands; she said, the first was colourless, like water, and the second was similar in colour, but had a different feel, being much warmer. I was not certain which was the water, and which the spirits of wine, as there was not a perceptible difference in colour, until I tasted the contents of the two phials, when the second was proved lo be the spirits of •These facts corroborate the statements of Mr. Smith and others. The let- ter of Mr. Berey in the Appendix, states some facts: he mentions one, the nam- ing a letter, written in sympathetic Ink. 201 wine,^ Soon after this period the Rev. Edw. Glover asked her, if she could tell the time of the day, by feeling- the surface of the glass, covering- the dial plate of a watch, her answer was, she had never tried it. A watch was gi- ven into her hands : she felt the surface of the glass, and very soon named the hour. She was afterwards so exact, that she not only named the hour, but the number of mi- nutes the minute hand had passed the hour. Once I gave her my watch, when the hour was twelve o'clock. She mentioned the hour, but observed, there was only one hand ; the minute hand being exactly over the hour hand. Mr. Glover assured me, that for several days he was afraid of speaking of the circumstance, lest he should he laughed at ; but, she so often repeated this experiment in his presence, and in that of other persons, that he made no hesitation in mentioning it. She told the co- lour of the different hands, whether they were of gold or of steel. She distinguished a gold from a silver watch. Brass and copper were also submitted to her touch, and she immediately discovered the one from the other. The colours of various seals and stones, whether mixed or not, were correctly named, as well as those of gems ; but it was only the colour, and not the nature of the stone, un- less she had before been acquainted with it. The eyes were covered with the goggles. t • The Rev. James Hornby, Rector of Win wick, if I mistake not, made a few experiments with different fluids, which were favourable to the opinion of Miss M'Avoy's powers, and were in some measure similar to those I had made. t In this paragraph are contained details which have thrown a doubt upon the minds of Miss M'Avoy's friends, and have confirmed, still more strongly, the suspicions of her opponents. As facts, no man who has not seen them will believe, that she named colours contained in glass bottles ; or between two pieces of glass : or the time of the day in a watch, through the glass ; or that she stated, which she afterwards did, the figures of objects at certain distances, with her hands placed upon the window : or, in one instance with her back to- C C 202 On, or about the 28th of March, Miss M^Avoy first made use of the magnifying glass, and by applying her fingers to the glass, she read the direction upon a label. The letters" seemed to rise, she said, up to the fingers. On the 19th of April, Messrs. Bickersteth, sen. and jun. and I, proceeded to St. Paul's Square. Mr. Thomas was also present. The mode of covering the eyes this even- ing, was one I had tried, for the first time, a few days be- fore, and consisted of a piece of gold beater's skin, suffici- ently large to cover the eye, extended, and sewed upon two pieces of velvet, which adhered to each othenr over the nose. The edge of the velvet could be turned up, so that, when the gold beater's skin was wetted and applied to the eyes, and then allowed to dry, it appeared closely adhering to the skin. This mode of covering wasplea- santerto MissM'Avoy than any other I had before used ; and it was a cooler application than either the goggles, or the Manchester shawl. She named the colour of t\'ards the window, and in reveral when covered with the goggles, or other covering, to the satisfaction of the bye-standers. Yet these facts have been witnessed by the Rev. E. Glover, by the Rev. Thos. Glover, by Mr. Thomas, by myself, and many other individuals ; and the experiments which have proved their truth, have been repeated by several persons. Mr. Samuel Pea» coek, late Surgeon in Liverpool, but now of Upton in Cheshire, corroborates one of these facts, by an experiment upon his waich, which he altered from the real, to an uncertain hour of the day, when Miss M'Avoy was covered not only with the goggles, but with gold beaters skin. He placed the watch with its face downwards, and covered it with a handkerchief: he then took Miss M'Avoy'shand and placed it under the handkerchief upon the glass, when she told the time of the day exactly as marked upoft the dial plate. — Vide his let- ter in the Appendix. Having been a witness of these facts having taken place, I iHust give thena that credence an unbiassed mind cannot, with justice, refuse ; but I certainly c«nnot deny, that the more 1 think upon the subject, the more I am puzzled to account for it ; because it supposes an influence not properly understood, and which cannot therefore, be satisfactorily explained. There can be no doubt the statement is correct, if w ^mm sBis^Q m^ (mL(s>wmm^ " Liverpool, July 30th, 1817, eight o'clock, p. m.— Waited on Miss M'Avoy ; found her very unwell, ex- pecting her fits to come on every minute : was unable to distinguish any colours ; declared that I was taller than my brother; perceived this when we passed her in the lobby ; told me, when I passed, whether I had my hat on or not. *' July 31st, eleven a. 31. — Found Miss M*Avoy in good spirits ; had passed the night in almost one conti- nued fit. Having completely blin(^folded her, we made the following experiments : — • " Experiment L — Presented six different coloured wafers, pasted between two plates of common window glass. She first laid her fingers on the red wafer, and named it. Does it not appear like a piece of red cloth ? She answered, no, I think it is a wafer, The six wafers 236 she named as follows : — dark ruby, red, black, green, stone colour, or light drab, pea green. She pointed out unasked, the cracks, openings, and deficiencies of the wafers. She said the glass was white. '* Experunent II. — She traced the outline of a very irregular figure, formed by squeezing the portions of two wafers, one black, the other red, between two plates of glass. " Experiment III — The seven prismatic colours being painted on a card, in water colours, she gave them the following names:— scarlet, buff, yellow, green, light blue, dark blue, or purple lilac. " Experiment IV. — The red and orange rays of the solar spectrum being thrown by a prism upon her hand, she said it appeared as gold. All the colours being thrown on the back of her hand, she distinctly described the different colours on the different parts of her hand. She marked the moments when the colours became faint, and again vivid, by the occasional passage of a cloud, without being desired to do so. The prismatic colours have afforded her the greatest pleasure which she has experienced since her blindness. Never saw a prism in her life. She felt the spectrum warm. The violet rays were the least pleasant.^ " Experiment V. — She perceived the coloured rings formed by pressing together two polished plates of glass. Feels them at the edge of her fingers flying before them. • She observed that the red rays appeared warmer and more pleasant than the violet; which, opinion coincides with that of Dr. Herschell, who proved the great difference of heat between the different prismatic rays. 237 Feels the reflected rays much better than the traoflh mitted: could just perceive the latter. " Experiment VI.— The prism being put into her hand, she declared it was white glass ; but on turning it, she immediately said, * No, it is not, it is coloured, it has colours in it ;' and she traced what she called stripes of colours, ribands, one coloured stripe above another. Could discover no colours on that side of the prism on which the direct rays of the light fell. " Experiment VII. — Several attempts were made to discover colours in the dark, by presenting different coloured objects to her hands, concealed under a pillow. She always failed ; every thing appeared black. On one occasion she said a green card was yellow. ** Experiment VIII. — She read a line or two in small print, by feeling the letters. Read through a convex lens at the distance of nine inches ; the focal length of the lens was fourteen inches.* Reads much easier through this lens than without ; the letters appear lar- ger, and as if they were printed on the glass. When a hand was interposed between the lens and the book, she immediately perceived it: a penknife was laid on the line which she was reading, and she named it. " Experiment IX. — A concave lens was put into her hand ; she tried to read at the distance of seven or eight inches ; said all the letters are confused ; she moved • The increased power of distinguishing minute oTyects through a convex glass is curious, because she does not hold the glass within the focus of the €ye, but as it were within the focus of the point of the finger, which would appear in this case, to serve the purpose of the eye. 238 the lens gradually towards the paper, and observed (he letters were very small ; could not read easily until the lens was laid on the paper. " Experiment X.— When she touched a plane glass mirror, could not perceive any rejBected image, but that of her own fingers. I feel, she says, the picture of my own fingers. ** Experiment XI. — Distinguished by the feel, the dif- ference between polished glass and cairngorum chrys- tal ; between silver, steel, gold, and brass : gold and silver have the finest feel. The silver of a watch case felt finer than ^e gold of the seal. She distinguished between ivory, tortoise shell, and horn : which last she called bone, but seemed to have meant horn. A pin which was sup- posed to be a chrystal, she pronounced to be glass; after- wards, on trial it proved to be glass. " August 1st, eleven o'clock A. Ai. — Miss M'Avoy much the same as yesterday. " Experiment XII. — Read, common print easily by touching apiece of window glass held twelve inches from the book ; at a greater distance she could not read, but could read much easier when the glass was brought nearer to the book. In like manner, and at the same distance, she discovered a sixpence, half-guinea, three- shilling piece, &c. she mentioned which had the head, which the reverse upwards, read the dates, pointed out on the sixpence, the position of the harp, lions, crown,- &c. She observed, unasked, that one half-guinea was crooked ; said it did not lie flat on the paper ; that the crown was downward ; that it was not a brass counter : does not think it is the shadow of the half-guinea which makes her know it to be crooked. 239 " Experiment XIII. — Declared, by feeling on the plaitt glass, at the distance of three or four inches, that two substances below were a red and a white rose leaf. Be- ing asked if it was not red and white paper, or cloth ; replied no, it is a ro^se leaf. ** Experiment XIV. — Again, she distinguished by the feel, the difference between stone and glass ear-rings, seals, brooches, &e. and pointed out one glass seal, which was supposed to be a chrystal ; being tried by a file, it proved to be glass. She named the colours of all the different articles. She says, stone feels more solid than glass, more firm.* *' Experiment XV.— Could not discover colours by the tongue ; but closing between her lips, the red, yel- low, blue, and white petals of flowers, she told each accurately. " iExperimentXVI. — She told the prismatic colours as accurately as on the preceding day, whether cast on ths back, or on the palm of the hand ; said she perceived something black on her hand ; observed when it moved, and when it was stationary. Being bid to move her fin- gers, she exclaimed. Oh I it is the shadow of my own fin- gers — which was the fact. ** Experiment XVII. — Uncovering her eyes, we cast the most brilliant prismatic colours upon her eyes, which she • Sight could have little or no influence in the distinction of glass from the harder stones; Instances are not wanting where she has described the colour and sort of stone in situations where only her fingers were in contact with it, and where no person, not even herself, if she had sight, could see the stone at the time she described the colour. We may therefore safely imagine this power to be derived from a similar source to that which occasioned her distinc- 240 received firmly, without either winking or shewing: any signs that she was aware of it. The most rapid vibra- tions of the same light did not produce the smallest ef- fect; her eyes remained perfectly firm and motionless. When the prismatic spectrum was thrown upon her mouth and cheeks, she perceived that there were colours on her face, but could not describe them so easily, or so accu- rately, as when they were thrown upon her hands. " Experiment XVIII. — She distinctly felt, through a plain glass, at the distance of four inches, the prismatic colours thrown upon a white paper. " Experiment XIX. — With her hands upon the win- dow, perceived two newly cut stones, of a yellow co- lour, lying one on the other against a wall on the other side of the street ; distance about twelve yards ; also, a heap of cast iron railing, piled upon each other. One of the company being dispatched to place himself on the ground, stones, rails, &c. she mentioned whenever he moved his position ; perceived him jump off the railing ; mentioned the colour of his dress correctly, only said a plumb coloured coat was black: mentioned two chil- dren accidentally passing by at the same time. She said they appear very small indeed ; the person who was sent appeared about two feet high, when at the distance of twelve yards ; as he came nearer, she observed, that she felt him grow bigger. All objects appear as if paint- ed on the glass.* " August 2d, eleven o'clock, a. m. — ^Found Miss M*Avoy much agitated ; was unable to distinguish co- • Vide note upon Mr. E.

Pulse 96. Her touch in the finest order. Experiment XX. — A stone ornament, in the shape of an orange, she took for a real orange, at the distance of two or three inches, feeling through the plain glass ; at the distance of fifteen inches it appeared like a nut, the brightness of the colour not diminished ; at thirty inches it appeared no larger than a pea — colour still vivid — still imagines it to be an orange. When she touched it, she immediately found out her mistake.* " Experiment XXI. — An orange and an apple, (stone ornaments) being placed at different distances, she told which was the nearest — distance, five or six inches ; felt them both upon the glass, but the orange appeared smaller, and therefore she thought it farther off.

If the object had been dis- tinguished by sight, the intervention of the glasses could make little difference in the size of it ; nor could the small distance have a material effect in dimi* nishing it. H h 242 distance her face appeared very small; saw her face also reflected from a plain mirror, holding the plain glass at three or four inches distance from the mirror. When the mirror was withdrawn, said her face diminished. All objects constantly appear as a picture on the glass she touches. " Experiment XXIV. — Perceived the sun through a plain glass ; also the reflected image of the sun from a plain mirror; was not dazzled with it; found it very pleasant. " Experiment XXV. — Several small articles were held over her head; she perceived them all in her plain glass; she asked doubtingly, if a three shilling piece was not a guinea; but raising her glass, and bringing it nearer to the object she corrected her error. " Experiment XXVI. — With her fingers on the win- dow, described a work-man in the street ; distance, ten yards ; a cart, loaded with barrels of American flour ; another, with two loaves of sugar ; a third empty ; a girl With a small child in her arms, &c. all accurately true, except that there were three loaves of sugar in the se- cond cart. "Experiment XXVII. — Could not distinguish by the touch the difference between pure water, and a solution of common salt in water. " Experiment XXVIII. — Accurately described by th^ touch several small engravings." 243 OF MR. EGERTON SMITH. Mr. Egerton Smith expressed a wish that the Memo- randa respecting Miss M*Avoy, published in the Liver- pool Mercury, should be inserted with the other letters in the Appendix of the Narrative, lest it should be supposed he believed in the powers ascribed to her. It gave me pleasure to comply with Mr. E. Smith's re- quest, and I then said I had no wish to gain a single pro- selyte to my opinion, unless he were convinced of the fact; but I could scarcely avoid thinking, that the proof Mr. E. Smith had given of Miss M'Avoy's powers, in his own presence, and, at the time, to the apparent con- viction of his own mind, would have more weight with the public, than the bare assertion of his disbelief of them, founded upon the opinion of other individuals. In this Continuation of her Case, I have also preferred to give his observations, together with his experiments, that the public may judge of them, rather than separate them from each other. Some time in September, 1816, I accompanied Dr. Renwick, on a professional visit he paid to Miss M'Avoy, at her residence in St. Paul's Square, on the east side. She was then between sixteen and seventeen years of age ; of pleasing and ingenuous countenance, and appa- ^^ rently of amiable and artless disposition. Her mother informed me, that in the preceding June her daughter had been attacked with hydrocephalus, or water in the bead, together with a paralytic affection on one side, and a complication of other disorders, which I forbear to enumerate ; because I am wholly ignorant of that part of the subject, which wil! no doubt be minutely detailed in the publication alluded to. According to her own state- ment, corroborated by that of her mother, the hydroce- phalus preceded, and, in their opinions, produced the blindness or gutta serena, under which she is supposed to labour, but which has been called in question, I under- stand, by some of the professional men who have vidted her.* Her mother, however, declared that the light of the sun produced not the slightest sensible effect upon her eyes; and some of the professional gentlemen who hap- pened to be present at one of my repeated visits, declar- ed that though some slight contraction of the pupil was perceptible upon the approach of a lighted candle to the eye, it was by no means such as uniformly occurs when the visual organs perform the regular functions. At my first interview, I learned from herself, what I had indeed previously been told by others, that she had re- cently acquired the faculty of distinguishing, not only the colours of cloth and stained glass, but that she could actually decypher the forms of words of a printed book ; and, indeed, could read, if the phrase may be permitted, with tolerable facility. To put these pretensions to the • If this opinion be questioned, it must be against the evidence of the symptoms which occurred previous to the convulsions which took place, and to the discharge of the fluid from the brain. S45 test, she permitted a shawl to be passed across the eyes, in double folds, in such a way that all present were con- vinced, that they could not, under similar circumstances, discern day from night. In this state, a book was placed before her, and opened indiscriminately ; when to our extreme surprise, she began to trace the words with her fing-er, and to repeat them correctly. She appeared to recognize a short monosyllable by the simple contact of one finger ; but in ascertaining a long word, she placed the fore finger of her left hand on the beginning, whilst with that of her right hand, she proceeded from the other extremity of the word ; and when the two fingers, by having traversed over all the letters, came in contact with each other, she invariably and precisely ascertained the word. By my watch, I found that she read about thirty words in half a minute ; and it very naturally oc* curred to us, that if, notwithstanding her supposed blind- ness, and the double bandage over the eyes, she could still see, she would have read much more rapidly, if her motive had been to excite our astonishment. And here it may not be amiss to state, that there does not appear to be any adequate motive for practising a delusion upon the public. Her situatioQ in life is respectable ; and her mother disavows any intention of ever exhibiting her daughter as a means of pecuniary remuneration. Fifteen months have now elapsed since the period at which she laid claim to the extraordinary faculty which has given rise to so much curiosity, astonishment, and perplexity; during which time the reputation of so wonderfuld a cir- cumstance has subjected her to the fatigue and inconve- nience of daily and almost hourly visits. According to her oven statement, her powers of touch vary very materially with circumstances. When her hands are cold, she declares that the faculty is altoge- ^46 ther lost ; and that it is exhausted, also, by long and un- remitted efforts ; that she considers the hours of from ten until twelve, of each alternate day, the most favourable for her performance. Her pulse during the experiments, has varied from 1 10 to 130 degrees. One circumstance, vrbich has created much doubt and suspicion, must not be concealed ; which is, that if any substance, for instance, a book or a shawl, be interposed between her face and the object she is investigating, she is much embarrassed, and frequently entirely baffled. She explains this, by saying that it is necessary there should be an uninterrupted communication between her fingers and her breath.* I leave it to others to draw their own conclusions upon this point; as my object is not to esta- blish any theory, or give currency to any mystery, but to relate the simple facts. I am, therefore, compelled to express my conviction that she can neither ascertain co- lours, nor the words of a book, in total darkness ; and, as many persons very naturally will ask, why has not such a test been proposed ? The reply must be, that as the young lady is not the subject of a public exhibi- tion and as an introduction to her is merely a matter of favour, it might not be very courteous or delicate, under such circumstances, to make any proposal which seemed to imply a suspicion that she was an impostor. There are persons, however, who, giving her implicit credit for the reality of the extraordinary powers to ♦ This opinion I have stated to be erroneous. The same effect wtis pro- duced when uncovered, or when a plate of glass intervened between her mouth and the object, through which she might have seen, if the object were distinguished by vision. I therefore presume her frequent failures, when obstructions of this kind took place, to have been caused by this interruption producing a peculiar effect upon the nervous system. 247 which she lays claim, will contend that it is altogether unfair to propose the test of total darkness. Proceeding upon their belief that she actually ascertains colour, &c. by the finger, or that the visual organ is transferred to the touch ; still they say that light is essentially neces- sary to produce that effect upon the surface of the body felt, which enables her to distinguish one shade from another : they add, that as there is no such thing as colour in total darkness, it is perfectly ridiculous to ex- pect that she should ascertain the various shades with- out the presence of that light which alone produces those shades. It is, according to their mode of considering the subject, as absurd as to expect an effect without a cause. It has already been stated, that, with the double ban- dage over her eyes, she read several lines of a book in- discriminately opened ; as it was possible that the letters of a printed book might have some slight impression sen- sible to an exquisite touch, I took from my pocket book an engraved French assignat, which was hot-pressed and smooth as glass ; she read the smallest lines contained in this, with the same facility as the printed book. A letter received by that day's post was produced, the direction and post mark of which she immediately and correctly decyphered. She also named the colour of the separate parts of the dresses of the persons in company, as well as various shades of stained glass, which were purposely brought. What 1 had seen at my first interview was so extremely astonishing, and so far surpassed any thing I had ever known or read of the powers ascribed to persons depriv- ed of sight, that I could only account for it on the sup- 248 position that she was not blind, and that she had some se» cret mode of discerning an object notwithstanding: the bandage, through which T myself, could not distinguish night from day, when it was applied to my own eyes. 1 therefore made the best apology 1 could for visiting her house again the same evening, having previously pre- pared myself with several tests, which I begged permis- sion to submit to her examination, when the candle was withdrawn. Not the slightest objection was offered to my proposal, and the candle was extinguished : her mother stationed herself before the fire, which was extremely low, and afforded so little light that I could not have read one word of moderate sized print, if it had been brought almost in contact with the bars of the grate. I then took from my pocket a small book, the type of which was very little larger than that of an ordinary newspaper ; observing at the time, that I was afraid the print was too minute ; to which she replied, that her fingers were in excellent order, and that she had no doubt but she should be able to make it out The can- dle, as was before observed, had been extinguished ; and her mother and myself were so stationed that had there been any light afforded by the fire, we must have intercepted it. Miss M'Avoy sat in the furthest part of the room, with her back towards the grate, in such a situation that I could barely discern even the leaves of the book which lay open before her; the title of which she proceeded to read with complete success, with the exception of one very minute word. 1 then presented to her a small piece of smooth writing paper, which was ruled with horizontal faint blue lines, between each of which were traced lines with a pen and black ink : there were also perpendi- cular red lines, between which were scored black linest 249 All these, with their direction and order, she determined without any apparent difficulty. She also told correctly the colours of a variety of pieces of cloth, procured immc)- diately before at a draper's shop. All the experiments hitherto described, as well as those which follow, were performed by Miss iVPAvoy, with the bandage before her eyes ; and as the shawl, which was usually applied to this purpose, produced considerable warmth and inconvenience, a pair of what, in the optici- ans shop.s, are called gogglers, had been provided, which so completely excluded the light, that no person who tried them, could discern the difference between day and night, when they were fitted to the face. As these gog- glers have been generally used when Miss M*Avoy has exhibited her surprising talent, it is necessary that the reader should have a correct idea of them. They are in- tended to be worn by travellers, to guard the eyes against the wind or the dust, and consist of two glasses, some- times green, fitted into a bandage of leather, which is pass- ed horizontally across the face, and is tied with ribbons round the back of the head. The gogglers provided for MissM*Avoy, instead of glasses, were fitted up with opaque pasteboard, lined with paper, and not an aperture was left through which a single ray of light could penetrate. Mr. Nichol, a scientific gentleman, who wasdelii-ering a course of philosophical lectures in Liverpool, having heard of this extraordinary property, applied to me to obtain an introduction to Miss M'Avoy, and I accompa- nied him to her house, along with Mr. James Smith, prin- ter, of this to\*n. iVi this interview the experimenti 1 have already detailed were repeated with complete suc- cess, whilst the gogglers were applied. One part of the performance was so truly astonishing, that 1 should al- I i 250 most hesita(e to relate it, if those two g-entlemen had not been present, to vouch for the truth. I had furnished myself with a set of stained landscape glasses, usually termed Claude Lorrain glasses. They were seven in number, contained in a frame. She ascertained the pre- cise shade of each correctly : one glass, however, appear- ed to embarrass her, and after considerable scrutiny, she said it was not black, nor dark-blue, nor dark-brown ; but she thought it was a very deep crimson. We did not know whether her conjecture was correct or not, as we could not ourselves ascertain the shade. By reflected light it appeared to us to be perfectly black ; nor was the flame of the fire, which was stirred for the occasion, visi- ble through it in the faintest degree. We had abandoned all expectation of determining tjiis point, when the sun suddenly emerged from behind the clouds ; and by that test, and that alone, were we enabled to discover that she was correct, as we could just discern the solar image of a very deep crimson. It has been said, and with some plau- sibility, that this must have been a bold guess upon her part: if not, it will puzzle our physiologists to explain, how a person reputed to be blind, with an opaque ban- dage also over her eyes, could declare the colour of a glass, which persons in full enjoyment of their eyesight, jand without any such obs(acles, could not discern by any other light than that of the meridian sun! At this meeting we were informed that Miss M'Avoy had recently found out that this extraordinary faculty was not confined to her fingers, and that she could also dis-tinguish the colour of an object which was brought in- to contact with the back of her hands. This was imme- diately made the subject of experiment by Mr. Nichol, who successively applied several objects which he had with him, to that part of the hand ; in placing which, he S61 \jged so much precaution, that I could not see them my- self, althoug:h my eyes were fixed upon his hands. She was completely successful, also upon this occasion. I have now giveii a faithful narrative of what I have actually witnessed, and what has been the subject of no- toriety and astonij»hment probably to thousands in this town ; and I shall only trespass further on the public p»i- tience, whilst 1 briefly state what has been related to me by several professional gentlemen of the town, as the re- sult of their (experiment's, since th6 time when I discon- tinued my visits, for a reason which candour obliges me not to conceal, although I am loath to say any thing which might wound the sensibility of an individual who has atforded me such amusemeiit, and uniformly received me with the utmost affability and politeness. I have ne- ver believed it possible that all the experiments I have witnessed were performed by the simple medium of touch ; and though t admit with our master poetj that" there ar& more things Hwixt heaven and earth than our phi/oso- phy dreams of,'' yet I could never divest myself of the impression that the eye was in some way of other con- cerned in these mysteries.^ tt Was a delicate point, as I before observed, to scrutinize i66 closely into all the mi- nutiae of a performance which was gratuitous, and politely conceded to a stranger, in her own house, and which, however it can be explained, is abundantly wonderful. A^ I dould not however, like some of my friends, become a proselyte to these miracles, I did iiot think proper any longer to harrass her with an impertinent and hopeless curiosity. She had begun to assume powers of a more ex- • If the reader look only to the assertions of Mr. Smith, he might receive them as proofs ; but if he attend to the facts related by the fiame gentleman, his assertions will weigh very light in the balance. 2h2 traordinary character than any I have described, and by proving^ too much, sho defeated her own object, at least in my imperfect estimation. I had seen b^r seven or eight times in the course of a very few weeks, previous to my declining^ my visits ; but stili continued to hear of her, from those whose faith had survived mine, and is as lively to the full at this moment as it was fifteen months ago. From these, her truly faith- ful followers, 1 heard that the experiments I have de- tailed, and many others had been repeated, with the boiled whites of eggs fixed upon the eyes ; and, also, that gold beater's skin had been used for the same purpose ; she had also begun to tell th6 hoUr and minute through the watoh glass, without opening the case ! But the most wonderful thing of all^ and Which forms an appropriate climax to the other mysteries, was the newly acquired power of ascertaining objects at a distance, with her back towards them ; and by simply stretching out the fingers in the directioti of such object ! I have heard it gravely asserted, and corroborated by herself in an interview on Monday last, that she has thus from her parlour window identified several persons passing through St. PauTs church yard, and declared the colour of their dress, &c.I!!'^ * This IS certainly one of those facts which cannot be believed upon mere hearsay ; and 1 hardly wonder at Mr. E. Smith not giving credit to it; but from his own experiments he must, at least, have supposed her to possess peculiar powers. It is certainly as reasonable, therefore, to presume from this examination, that the success he met with might be really owing to her varied powelrs of touch, not to any peculiar acuteness in vision ; because there are the strongest proofo of the first opinion being correct, not only from what he has stated, but from the circumstance that some of his own experiments have been corroborated by those of other individuals. Of the latter opinion, of her possessing a peculiar acuteness in vision, Mr. Smith has given no proof. The fa«t of her stating objects thxough the window, or upon therailing of th* 853 In the preceding protracted, but faithful narrative, it has been my object to detail facts rather than to indulge in theories. Whatever contrariety of opinions may prevail on this point amongst true believers or sceptics, there are two conclusions, to one of which they cannot withhold their assent : — First — Either Miss M'Avoy, although blind, possesses the faculty of distinguishing objects and colours hy the touchy or some other means than the eyes ; — or, Secondly — Miss M'Avoy, reputed to be blind, and with a bandage over her eyes, through which no other person can see ; in a place, also, so dark that others can distin- guish little or nothing, can see better than any other person. Leaving to physiologists the farther investigation of this extraordinary case, I shall, for the present, conclude, by affixing to the preceding statements my name at full length, which I conceive to be indispensable in the pre- sent instance. (Signed) Egerton Smith. Liverpool, Sept. 2, 1817. Church yard, or in the street, has been witnessed by many persons. Miss M'Avoy was generally covered with the goggles, standing in a natural position, with her face neither elevated nor depressed, but the middle of it, as it were, meeting an horizontal line drawn from the Communion end of St. Paul's Church ; so that agreeing for one moment with her opponents, she could see down the sides of the nose, the only way, supposing she had the faculty of vi- sion, they assert she can see, when facing objects in the street, or in the Church yard, (the furthest distance being seventeen feet and nine inches from the win- dow), a line drawn from the point or sides of the nose, wouUl fall into the par- lour where she stood, and of <;ourse could not be directed to the object she described. 254 From a due consideration of the proofs adduced above*, the Public will have a better opportunity of judging cor- rectly, than it could have done, by reading only one side of the question. Miss M'Avoy is also still in being, so that individuals may make, if they choose, a personal in- quiry into her state of health, &c. : by these means they can form their own opinion, which ought to be more sa- tisfactory to themselves^ than that of any other per- son. It is probable also Mr. Sandars will now agree with me, that partial statements of a case of this nature can never be effective in elucidating the truth ; that the open avowal of those circumstances which were for or against Miss M'Avoy^ could only convince an impartial mind ; that, in attempting to influence the public against an oppressed individual, from so slight an evidence as that produced by himself, from an almost momentary ex- amination, or from the assertion of others, whom he has dragged into his service upon this occasion, he has laid him- self open to public censure ; and that, although for a time he has had the ball at his foot, and has caused muchoblo- quy to attach to Miss M*Avoy's character, he will yet find the Italian adage to be true, that " Ogni medaglia ha il suo reverso" APPENDIX.

Sir, " I have received your note, requesting me to state the circumstances to you which occurred during my visit to Miss M'Avoy, on the 24th September last. I will, agreeably to yoiir desife, and to the best of my recollection, relate what I saw and heard. It may be proper to inform you that Dr. Jardine, Mr. By water, and myself, had a meeting at my house on the same morning, for the purpose of arranging our plans of experiments to be tried in the most satisfactory manner to ourselves, and to give the least trouble to the young Lady, of whose extreme irritability Dr. Jardine had most carefully apprised us. At the time appointedlVC^ o'clock,) accompanied by Mr. Bywater, I met Dr. Jardine, and Mr. Hargreaves at Mr. Hughes's, in St. Paul's Square; as we had been led to expect we should have had Miss M'Avoy's company to ourselves exclusively, we were much disappointed, on entering a small room, to find her surrounded by at least thirty ladies and gentlemen; the atmosphere of the apartment was certainly oppres- sive, and when I was informed Miss M'Avoy had already been visited during the morning by three or four large parties, 1 began to fear the experiments we had prepared w^ould remain in our pockets one in particular, con- f rived by Mr. By water, we much wished to have tried; 1 think it would have been conclusive ; so many were presenting subjects to her, and her alleged powers ap- pearing to be quite exhausted, we agreed not to try it. When her faculty of touch seemed to return, by her tell- ing the colours of shawls, coats, &c. I presented a card upon which 1 had put some broad stripes of the primary colours; she told these accurately, except the yellow, which she called lilac, the exact opposite to yfello^v ; her eyes were then wide open without any covering. The card was reversed, the coloiirs downward, and presented to her; after feeling a short time, she said she could not tell the colours. Soon after this, Mr. Thomas proceeded to fasten goldbeater's skin upon her eyes ; the lids being down, I was attentively watching this operation ; when completed, I observed you on your knees by her side, looking steadfastly at her eyes; and you exclaimed, ** she can see, the eyelids are not quite closed ; if my eyes were similarly situated, I could see also."' From the infor- mation we had received of her nervous state, I instantly anticipated the downfal of all our hopes fbr that day, and begged of Dr. Jardine to call you asidfe and recom- mend a (liiferent conduct. At that time, no doubt, the whole of us felt very angry with you ; but upon reflec- tion, this feeling soon left me, as I think strangers should have been apprised of her great sensibility, either by those who introduced them, orby a written notice placed in a conspicuous part of the room. The goggles were then put on ; all power left her ; Mr. Thomas said her hands were too cold ; she sat a considerable time in this situation ; the heat of the room was great; she appeared to be faint, and was recommended to retire for a short time ; the goggles were taken off, and she did so. Di- rectly after This, I found you with the goggles in the kitchen, attended by several gentlemen. 1 assistedin fast- ening them upon your face ; this done, Mr. Bywater said, •^ If you can see now you are a clever fellow." A watch tvas presented to you, the time of which yon told accu- rately ; the same of another ; the strings were then tight- ened about your head, and another watch was olfered, by which yon could not tell the time, but said it wound tip on the face of it ; this was correct. 'J^ We returned to * Contrast this account with that of Dr. Jardiiie, pages 143 and 144 of the Continuation of the case. Miss M*Avoy, who was then in the back parlour, with the goldbeater's skin only over her eyes. I was told she had just before read the address of a letter; when I en- tered, she was passing her fingers over the top line of the Liverpool Patent Trade List, which she read correctly, also a line in small print under the above. She was then conducted to the front parlour ; the goggles were applied; 1 assisted in placing and holdinjr the boxes so that the upper edges should be under the projections of the eye-brows, whilst a lady was tying the strings behind her head. During this ceremony. Miss M'Avoy put up her hands to remove them, saying they were too low down. This I prevented, and took care that the cross- ing strings under the nose were properly fastened. I desired her to hold up her head a little, that we might examine the sides of the nose. I was convinced she was perfectly blindfolded ; Mr. Bywater observed, " If she can read now, she must obtain her means of sight from some other source than what I and many others have long suspected, viz. by small apertures being left by the sides of the nose." Some experiments were of- fered, but all power had left her. Miss M'Avoy retired soon after this, and the exhibition terminated. When the Rev. J. Yates said something to you respecting the abrupt exclamation you had used, most of the company had left the house ; I was fastening some goldbeater's skin upon one of your eyes (through which you plainly distinguished colours) when Mrs. Hughes entered the room, and with some warmth said, " Don't mind him, Sir, he is not worth attending to ;" and made use of language which I thought you bore very patiently, by not replying, except by making an apology, to her for what had happened, and appealing to the ladies then present. Soon after this, you with two ladilUquitted the house, leaving Mrs. Hughes, Dr. Jardine, Mr. Thomas, and myself. We conversed a (ew minutes upon the oc- currences that had taken place. Mrs. Hughes said she did not know who had introduced you to the party, and seemed to suspect you had come with Dr. Jardine ; this he denied ; she then said you had intruded without any introduction, and she would take care you should not come again ; your conduct had made her daughter ex- tremely ill ; she was up stairs, and she (Mrs. H ) was sure she could not recover it that day. We all express- ed our sorrow for what had happened. In taking leave, when descending the steps at the house door, acciden- tally I turned my head, and to my surprise saw Miss MvAvoy standing at the kitchen door, with an infant in her arms, I had no sooner caught a glimpse of her than she skipped out of my sight, as if wishing not to be observed. I have endeavoured to give you as correct an account as my memory retains of the facts, and am not at present aware of the motives you may have for requesting the above narrative unless they arise from the note inserted at the bottom of your letter to Mr. Hughes, introduced in Dr. Renwick's late publication.^ 1 am, Your obedient servant, JnO. TURMEAU. Bold-street, Nov. 5, 1817. No, 2,— The Letter of an Anonymous Gentleman. The goggles were applied. A book which a gen- tleman present happened to have in his pocket, was given to her ; after passing her fingers repeatedly over a particular line, she placed the book upon her knee, and covering her right hand with her left, she read as follows: "I will not name them, replied Zelia." The line, as printed, ran thus : " 1 will not name them, was Zelia's answer." A piece of crimson and white paper was put into her hand, with the coloured side down ; after feeling at it some time, she decided that it was black and white. On afterwards holding the paper up to the light, the crim- son colour had very much the appearance of being black. The same piece of paper, with the coloured side up, was again given to her, (a sheet of writing paper having been previously interposed between her face and her * Mr. Turraeau. it would appear from this paragraph, surmises that Mr. bandars s pamphlet was published out of spleen to me.

A letter was then given her, (the sheet of paper bein^ interposed, as in the last experiment,) and she was re- quested to name the colour of the wax with which it was sealed, and likewise what were the letters upon the seal. She said the seal was black, but she could not distinguish what the letters were. The seal was red, and the letters upon it were sufficiently large to have enabled a person with any delicacy of touch to have told what they were. No. S.—J. T. Roster's Letter to Mr. Sandars. Dear Sir, In compliance with your request, I will endeavour to recollect some of the circumstances that occurred at my short visit to Miss M*Avoy. I was introduced by a friend, and found assembled a very nu- merous and highly respectable company of ladies and gentlemen : it was not at the house of her stepfather, but, as I understand, the adjoining house, the parlour of which was more commodious. I kept no memorandum^ but on reference to Dr. Renwick's publication, I observe by the names of part of the company, that it must have been on the 23d of September. After blindfolding the young Lady in the usual man- ner, a watch was given into her hand, and she told the time exactly, that it wanted six minutes and a half to three. The routine of experiments were then gone through, of coloured cards, gowns, shawls, silks in a phial, and also the mirror ; this she held in her hand, and a gentleman looked into it over her shoulder ; she could not make out any thing; 1 remarked to him, that if he would lean farther over, so as to see the Lady's face in the glass, she would more readily receive the impression ; he did so, and she then described his countenance and the colour of his hair. She was soon after desired to feel the hair of Mr. William Earle, and tell the colour. She either said positively, it is red, or interrogatively, is it not red ? This gentleman's hair is very ^rey, and he wears powder. She was next desired to describe the colour of the hair of Mr. EarIe,who sat nearer to her and more forward ; she felt it, bat said she could not tell. The room being heated by the crowd of company, she was advised to retire for awhile. In her absence, I sug- gested to Mr. Earle, that if the young Lady would per- mit him to lay his head upon her lap, I was confident she would discover the colour of his hair; immediately on her return he did so, and without hesitation she said it was white. The elder Mr. Earle does not wear pow- der, but his hair' is also very grey. Some few other ex- periments were made, when this gentleman said, he had heard that Miss M'Avoy could discover by the feel, what was written on the inside of a hat, and he presented to her the concavity of his own hat sideways ; she put her hand into it, and said she felt nothing ; on this a card was given to her, coloured on one side a bright red, and on the other blue ; she felt it a long time, and at last she could not distinguish the colour ; here some one re- marked that ihe fatuity was gone, or going. I must confess that from what I had witnessed, it ap- peared to me that this intermitting of what is called the young Lady's faculty, together with the alleged neces- sity of a free communication between her breath and the object to be distinguished by the touch, are occasionally extremely convenient. Your's, dear sir, very truly, J. T. KOSTER. Ath November, 1817. JVo. 4. — Mr. C Worthington' s Letter to Mr. Sandars. Dear Sir, In compliance with your request, I purpose stating, as accurately as I can, my observations during a visit I made to Miss M'Avoy, I think on the 2d of September last. I shall confine myself solely to facts. Dr. Jardine kindly obtained permission for me to see Miss M'Avoy, and introduced me to her. As I arrived some time before Miss M'Avoy made her appearance, I had an opportunity of examining into the means employed for covering her eyes, when expe riments are made. I was shown tlie pasteboard screen described in Dr. Renwick's " Narrative," and the mask with the goggles, of which the Dr. has given a sketch in the frontispiece to his publication. Wishing to satisfy myself that the goggles were an effectual blind, I had them tried on myself. Dr. Jardine had lied the strings tighter, 1 believe, than Miss M'Avoy could have borne. On looking down my nose, I found I could distinguish objects immediately below me, without difficulty. I saw my watch-chain, for instance, I was glad to get rid of the mask ; it made me extremely hot, and occasioned an un- easiness in my eyes, which continued several hours. When Miss M'Avoy entered, her hands were hot, and the power had left her. I asked permission to examine her eyes, which she granted with great good humour. They appeared somewhat dim, and placed deep in the head. On exposure to a strong light, the pupils con- tracted as much as those in healthy eyes, under similar circumstances, but I think rather more slowly. I took an opportunity of darting my fingers rapidly towards the eye ; it did not blink. Miss M*Avoy, after cooling her hands with a wet sponge, said she would try whether the power was re- turned, before her eyes were covered. Accordingly, some bits of coloured silk were presented to her one by one ; I was standing close to her, and looked intently at the eyes, to watch their motions. The three colours first given her were blue, scarlet, and pink ; she named them rightly, after having felt the bits of silk for a few seconds ; but I observed the eyes were previously direct- ed to the objects, with a rapid and instantaneous glance. The next bit of silk was a drab or fawn colour. She did not tell the colour, nor were the eyes directed to it. The pasteboard screen, cut to fit the face, and having its edges covered with cotton-wool, was then applied.. On looking under it, rays of light were perceived between it and the nose. These I effectually excluded, by gently insinuating a little cotton into the interstices that admit- ted the light, so that it was impossible she could see any object placed immediately under the pasteboard, even if she were not blind. Unfortunately, the power now left her, and she failed in every attempt. In answer to sv 10 question I put to Miss M'Avoy, she said she preferred the goggles to the pasteboard. Miss M'Avoy now retired, and was absent for a con- siderable time ; on her return she appeared cheerful, and said she believed she should now succeed. The goggles were put on. She dislinguished colours, told the time of the day by a watch, read a few words from a book, a written note, and an address card, in her usual manner. During these wonderful performances, one of the com- pany interposed a piece of printed calico between her face and the object; she immediately perceived it, and pushed it away in rather an angry manner. On the gog- gles being taken off, a gentleman of high rank in the navy closed the eye-lids with his fingers ; and the power instantly left her, though a few seconds before she seem- ed in full possession of it. I regret 1 could not prolong my visit, and witness a few more performances of this extraordinary young lady. I have now given you a full and somewhat desultory account of what I saw on my visit to Miss M'Avoy, and have stated impartially every circumstance that might appear either to confirm, or invalidate the idea of her beingblind. I shall make no comment, but comforting myself with the conviction that " truth is mighty, and will prevail," I subscribe myself Your very sincere friend, C. WORTHINGTON. Noo. — The Letter of a Gentleman to Mr. Sandctrs. Sir, In October, 1816, Mr. Bradbury, author of Travels in America, acccmpanied by a friend, visited Miss M'Avoy. His friend had seen this young lady se- veral times before, and from witnessing some experi- ments that were tried upon her, was of opinion that she could see ; but being anxious that Mr. Bradbury should also observe her, he prevailed upon him to visit her. After a few experiments, Mr. B. was so well satisfied that Miss M'Avoy could see with her eyes, that he ceased to examine her further, and seated himself by the fire to wait until his friend was ready to depart. His friend 11 made a few more efforts, to be convinced whether the opinion he had previously entertained was well or ill* founded, and proposed, as a final test of her powers, that she should determine, with her hand behind her back, the colour of a piece of cloth which he brought with him ifor that purpose. After feieling it for a short period, and being informed that she was mistaken in the colour that she guessed it to be, Miss M'Avoy requested permission to use her other hand, which of course was instantly acceded to. Aher some time had elapsed, in which she was unsuc- cessful in her efforts to determine the colour, her mo- ther, who was in the, room, and had been engaged in affixing leather to tiie goggles, handed them over to Mr. B's friend, arid asked his opinion, whether it wai possible, in their amended state, for a person to see with them ? He unwarily put them on him for a few moments^ to ascertain the point demanded, and when he took them off, he was surprised t6 find that Miss M*Avoy could Iheh, state correctly the colour of the cloth. He shortly after took leave of her, as he was extremely desirous of learning from Mr. B. what had transpired, ddring the time he had incautiously put on the goggles. Mr. B. was equally anxious to communicate what he had observed duHng that period, in which, although apparently heedless of what was passing, he was an at- tentive observer. Mr. B. then related, that as soon as his friend had put on the goggles, he saw Miss M*Avoy rapidly glance at himself and his friend, and acting as from an apparent conviction of not being observed, she drew the cloth from behind her back, gazed at it quick- ly, and restored it to its former situation, before the goggles were removed from his friend's eyes. This fact Mr. Bradbury has related to several respectable Gen- tlemen, who are fully satisfied of his candour and inte- g;rity. Liverpool, 6th Nov. 1817. No. 6. — Mr. hutwyche's Leiler tb Mir. Sandar^. Sir, I received your communication on the sing^ular case of Miss M'Avoy, from which 1 understand b 12 that, iikie myself, you have doubts of her pdssessiug that extraordinary talent, which some persons, even of the Faculty j give her credit for. I have no particular ob- jection to your giving publicity to a detail of those ex- periments I witnessed at her residence some months since ; but being anxious to afford this young Lady a fair opportunity of making a convert of myself to this new Theory, 1 declined replying to your note sooner, under the hope that I might have prevailed on her and her Mother to have allowed another interview, and if possible to have removed the spell, which renders me for the present incapable of believing. For this pur- pose, I waited on Mrs, Hughes yesterday, and candidly informed her that I had been applied to by yourself, for these particulars, but that 1 should have much greater satisfaction in declaring my belief than my doubts on this subject. I was desirous of placing a few pieces oil coloured glass, in such a situation that they could not be seen by any human being, though with as much light thrown upon them as might be required. The result of "this simple experiment would have removed all my doubts, or have confirmed all my suspicions. The in- disposition, however, of Miss M'Avoy, and the great objection of her Mother to admit any one in correspon- dence with yourself, left me no alternative but to pro- ceed with the facts I am already in possession of. i think it was in the early part of February, I was in^ duced to pay this Lady a visit, in company with Mr. J. Breretonand another Gentleman, for I was unwilliug^ on bare report, to give credence to a statement so very improbable. Previous to going, we prepared ourselves with a few slips of paper, about seven inches in length, and two inches broad ; in th*j centre of one of these was written the word Liverpool; on another was traced an oval, on a third a square, on a fourth parallel lines cross- ing each other at small distances, none of which occu- pied on each slip of paper a greater space than about two inclies. We also provided ourselves with some slips of coloured papers, from a neighbouring shop. In this shop were exposed for sale some valentines; one of these we purchased, on account of its displaying a varie- ty of colours, but the subject it was intended to repre- sent was so rudely executed, as to require some inge- nuity to discover the intent of the artist. This valentine was surrounded with a wreath of [lowers, and the u.-uai 13 emblems ; and in the centre was the figure of a sailor. Being thus prepared, we proceeded to the house of her Fatiier ; the door was opened by a young woman, who appeared to look attentively at each of us, when ex- plaining the object of our visit; we were requested to walk in, and on entering the sitting room, were surprised to find this identical young woman the individual in question. Not being sufficiently skilled in the know- ledge of the formation of the eye, or in those nice symp- toms which in doubtful cases determine the non-exis- tence of vision ; we made no other remark, than by placing Miss M'Avoy before the window, and inter- vening the hand between the light and her eye, we plainly discovered a dilatation and contraction of the pupil. Having thus far proceeded, the goggles were produc- ed by her Mother, who placed them on the face of her Daughter in such a manner as left us to suppose that a person so blinded could not see in the least. After this, some minutes, perhaps ten or fifteen, elapsed, during which time she frequently breathed upon her fingers, informing us, that the moment had not yet arrived when the feeling faculty had commenced. At intervals, she raised her hands to the bandages, adjusting them appa- rently for ease, though it had very much the appearance of being done for the purpose of admitting a channel for the commuuication of light. We were, however, careful during this period, to give no opportunity of evincing to her any suspicions. At length she declared herself in readiness, and placing her fingers on a parti- cular spot of the slip of paper, where the word " Liver- pool" was written, she pronounced it without hesitation. The same success followed on every other slip of paper put into her hands. In the mean time, the valentine lay in a careless manner on the table before her, so that if there were any channel of light beneath the goggles, it could not have been dilTicuit to see the most prominent objects delineated U]>on it. It was then taken up and presented to her, but tlie experiment, though partially successful, proved rather more than was desirable for her fame. She first placed her fingers on the sailor's hat, and without proceeding further, said it was a man; then bringing her fingers a little lower, described tha colour of his jacket; and intending to proceed down- wards, she declared his trowsers to be striped with pink, 14 which was in fact the case, but unluckily for Miss M'Avoy, her fingers had not as yet come within one inch of that part of the dress, the colour of which she had pronounced, but were exercised in feeling or rather rubbing the plain part of the paper. She had taken the precaution, during the experiment, to cover the fingers with which she felt the object, with her left hand, in such a manner as surprised us; for it partly excluded the light, and prevented any person opposite from see- ing where the fingers were placed ; but from the acci- dental situation of Mr. Brereton, and myself, who vvere sitting on the same sofa, and leaning, or rather stooping |)ehind her, we were able to trace all her operations without excitina: suspicion. What particularly struck ^ach of us on this occasion, was, the prompt manner in which she first declared the object, before she had trac- ed further than his hat. Here it should be observed, that Miss M'Avoy had not then so far advanced in the science of seeing with her finger ends, as to determine objects at the most trifling distance ; for we discovered, as we proceeded with other experiments, that not only actual fcontact, but very severe rubbing^ was necessary in some cases, before she would venture on pronouncing the colour of the articles in her possession. But to pro- ceed, she was going on with accuracy in describing the colours of the surrounding emblems, when the Gentle- man before named intervened a sheet of paper between her eyes and pngers. The power was in a moment gone, and she was unable to procead with her description of these minor sketches until the "paper was removed, al- leging, that if the communioation between her breath and fingers was interrupted, she eould not go on. There lay upon the sofa vvhere she was sitting, a num- ber of small pieces of coloured silks, cotton, velvet, &c. &c. many of these we put into her hands,- both before her face and behind her back ; she sometimes failed, but in most instances described the colours with dorreet- ness. This was during the time she had the goggles on ; but it must be remarked, that these pieces were lying there when we came in, and perhaps had been there for weeks, during which period they might have been so often practised upon, that the very shape would have been sufficiently familiar, to have enabled her without any additional faculty than that of memory, to have de- termined the colour of each with correctness. le Our experiments were now drawing to a close, whea Mr. Steele, from London, entered the room, with a new kind of apparatus, which appeared to possess all the ne- cessary powers of interrupting sight, and yet admitting the needful communication of the fingers with the mouth, which was declared indispensable, for the pur- pose of breathing on them occasionally when touching the object, the colour of which was to be identified. — This apparatus was nothing more than a small sheet of pasteboard, out of one side of which a circular piece was cut, so as to admit her neck. Being placed under her chin, the goggles were considered unnecessary, and were removed ; as there could be no doubt of her pos- sessing the faculty of stfeing with her fingers, if with this projecting appendage she could describe objects, and tell the colours of them when placed beneath it.— It was not our business to determine if the Lady could see with her eyes; our doubts only related to her pos- sessing that faculty with her hands. I think the first trial we made ua4er this new arrangement, was with a watch. Now it happened that two Gentlemen present had gold watches, very nearly alike in size and fashion. One of these was held carelessly, though designedly, at such a distance from her face with the dial upwards, as to be seen, if she had the power and inclination to look at it. A few minutes elapsed in conversation, when it was proposed to put a watch into her hands, beneath the pasteboard, and taking the one just alluded to, for that purp9;ge, I professed to give it her, but in fact put ano- fher watch into her hands, the fingers of which had been privately altered ona hour forward. She drew her fin- gers over the glass, and declared the time to a minute ; but observe, it \Yas not the time of the watch she held in her hand, but the time of the watch I held concealed in mine, the one which had previously been placed care- lessly at a distance with the dial upwards. This artifice she was not made acquainted with, and an exclamation of " astonishing'' being uttered by some one of the par- ty, she concluded that every thing so far was right. — The other watch was then put into her hands, but after feeling at it some time, she declined pronouncing any opinion, and placed it upon her lap, with the face downwards. Her Mother, who was then in the room, stepped forward, and taking it up, placed it on the table before her Daughter's face, with the dial upwards, de- 16 siring Margaret t» try something else, that presently she would be able to name the hour. From the situa- tion in which the watch was placed, we believe she would have succeeded, but we removed it, and she had not the opportunity. In the course of these experiments, she had occasion for her handkerchief, which had been lying on the sofa near her, she felt on each side without finding it; she then stooped forward in the attitude of a person look- ing, and without feeling in the manner she hsid done when sitting upright, placed her hand direct upon it on the floor. We then put into her hands the slips of pa- per she had before described with accuracy, when the goggles were on ; but this new contrivance of the paste- board had dissipated the miraculous power, and her fingers became, like the fingers of other persons, per- fectly blind. Mr. Steele then drew from his pocket se- veral pieces of silk, of various colours, which were given into her hands behind her back ; of many of these .she told us the colour with the greatest correctness : but there was a trifling circumstance attending these trials, which must not be passed unnoticed, and which tend- ed more than any either occurrence to shake our faith, and rank us among the unbelievers. We had expected that iu these experiments she would have evinced great delicacy of touch. On the contrary, every article was handled with a roughness, which would rather tend to ascertain whether they were hard or soft, than to receive the rays of light or colour. This remark was particu- larly applicable when practising on each piece of silk introduced by Mr. Sleele ; the edges of which she liter- ally tore^ and frequently bringing her hand to her mouth under pretence of warming it, small shreds were obser- vable attached to her nails\ and on breathing upon her fingers, they fell in such direction, that if Miss M'i\voy really could see, there was but little risk in ffuessinr/ at the colour of the remaining piece behind her back. Un- willing to leave any little circumstance which occurred on this day unnoticed, I trust I need not apologize for the length of this letter ; and as it does not fall within the range of my talent to enlarge on the philosophical part of this extraordinary endowment, I shall leave the sub- ject in better hands, by subscribing myself Your most obedient servant, Thomas Lutwyche, Liverpool, Nov. 12, I8I7, 4, St. James's-road. 17 Particulars of what passed on the ISth of October. A number of experiments were tried on Miss M^Avoy, in some of wliich she was successful, in others quite the reverse. She had two glass phials put into her hands, in one of which was water, and in the other spirits of wine; she named each very accurately, which Dr. R. regarded as a very extraordinary circumstance ; but up- on examination, it appeared, that although the phials might be of equal weight, they were not of equal size, one being much longer than the other, and the cork»j were not (as they ought to have been) sealed with wax ; indeed they had not the least covering over them, to prevent any one, who had a peculiar fine sense of smell- ing, from ascertaining the difference. A gentleman pre- sent gave into Miss M-Avoy's hands a seal, and request- ed her to tell him the colour of it ; he placed his hand between the seal and her face, and she declared the seal to be black, whereas it was white. At the close of the experiments, another person present expressed an opi- nion that Miss M'Avoy could see; upon which Dr. R. proposed that the goldbeater's skin and the adhesive plaster should be applied to that person's eyes, which was assented to, and uncommon pains were taken by Dr. R. in placing them, so as to prevent all possibility of seeing. When fixing them. Dr. R. said, " Now close your eyelids," to which an answer was returned by some one, " You were not so particular with Miss M'Avoy." However, the request vtas complied with, and when the bandages were properly placed, a watch was presented, and the hour was immediately pronounced ; a glove was given, and the colour was told; a letter was produced, which was read with great facility, although the writing was very small. "-'^ The Letter of Mr. Turmeau to the Editors of the Li- verpool Mercury. Gentlemen, When I gave Mr. Sandarsa narra- tive of the circumstances which occurred, during my vi- sit to Miss M*Avoy, on the 24th of Septemberlast, I was * j^e my account of this meeting in the continuation of the ca^e, page » & t>. IS then, and am still, fully convinced Mr. Sandars was in search of truth. I related to him a series of facts, and did not expect to be again called on, either directly or indirectly, in this mysterious affair. However reluctant J may be to obti'ude myself on the public, what has lately taken place has compelled me to do so, in my own de- fence; and 1 shall, therefore, proceed to give you an ac count of a circumstance, which, I think, ought to be ful- ly and fairly stated. On Sunday morning, the 11th instant, Mr Dale called Upon me, — and after som6 introductory conversation concerning the case of Miss M'Avoy, he said, that the statement I had inserted in my letter to Mr. Sandars respecting my having seen this lady with the child in her arms, at the kitchen door, at the time her mother declared her to be very ill, up stairs, had made a great impression against her ; and that, from what the family had told him, he Was almost convinced I must have been mistaken as to the person 1 saw. It might have been the effect of optical deception — that a Miss D ^ was the lady I saw with the infant. — I instantly told Mr. Dale, that I was ready, at anytime, if called upon, to make oath, that it was Miss M'Avoy, and no other person, I saw in the situation described in my letter to Mr. Sandars : he then said, the matter was likely to take a serious turn, as the other j5arties were also ready with their oaths. T told him, that ^as no affair of mine. — Mr. D. pressed me to see Miss D , by calling upon her, with him, to make myself certain as to her person, before coming to extremities. To oblige hirii, and not to appear perverse, 1 consented to this ; but did not inform him, at the time, that 1 was acquainted with this lady, and had known her for many years: this the parties discovered afterwards, as you will find in the sequel.— Upon any day, at half past three o'clock, I said I w^i ready to accompany him. We did not meet again till the following Sunday, when Mr. Dale called upon me ; but, instead of going to see Miss D — — , I was conduct- ed to the house of Miss M'Avoy, whom we found in the back parlour, apparently in a very bad state of health, constantly twitching and breathing, as if convulsed. From enquiry of my medical companion, as to these • At the express desire of this lady, ber name is omitted. i^ symptoms, 1 was informed, they were caused by a palpif tation of the heart. After the usual salutations, I heard the name of (I believe) Mrs. N mentioned as the la- dy I had mistaken for Miss M'Avoy, and she was sent for. When I found what game was playing, 1 told Mr. Dale, I should not say a word, before the parties, in con- tradiction to any assertions they might advance (having already witnessed the pretended ill effects of abrupt be- haviour to the young lady.) Mrs. N sent word, by the messenger, she was at her dinner, and " as soon as she had done, and cleaned up, she Would come in." Shortly after this, she made her appearance. My in- dignation was now greatly excited at the attempt to en- trap and to impose upon me; however, I kept silent, and listened to what they had to say. To shew the contrast between this woman and Miss JVPAvoy, I must give a de- scription of her person, which is altogether above twice as large as that of Miss M*A . She appears to be be- tween 50 and 60 years of age, With the strongest marked physiognomy I ever saw ; very dark complexion, and one eye-ball completely turned in. I cannot blame the wo- man for her unfortunate appearance, particularly as I have a cast in one of niy own eyes; but I give you this sketch to shew the contrast, as you know Miss M*Avoy is a most delicate and sickly looking girl, — and that I could not have erred, through a deceptio visus, as con- jectured by my medical friend. She said she was ready to swear, that it was she who held the child, but did not appear to be certain as to the day. Miss M'Avoy told us, she had been luminous, or transparent, a few day^ before, but could not then exhibit her alleged powers. With sensations I need not describe, I was glad to leave the house ; and, when in the street, t told Mr. Dale, that if it was possible, I was more firm in my belief that Mis.^ M'Avoy was tlie person I saW with the infant. Mr. D. said he wished me to be convinced of Miss M'Avoy hav- ing (he powers ascribed to her, and that I should have the earliest intimation and opportunity of witnessing the wonderful gift she occasionally has ; but, that if she knew I still persisted in what I had asserted, no future interview could possibly take place between us. — Since this, I have written to Mr. Dale, informing him, he is at perfect liberty, to state to the parties my opinion of them, as I have not the least inclination to visit the young lady again. I am far from thinking my friend, Mr. D. hag so connived, in anyway, at this plot ; but fear he his misled by his enthusiasm in the cause.^ At the moment I saw Miss M'Avoy, in the situation before described, on the 24th September, 1 told Dr. Jardine of the circumstance ; and my surprise, after what her mother had just before stated, that "her daughter was very ill, up stairs," &c as related in my letter to Mr. Sandars. The doctor, no doubt, recollects my having: done so : I could have no motive in stating- a falsity. — Why did they not contradict it at the time? But, Gentlemen, if any further proof of my accuracy be necessary, I could, if I thought proper, give the name of a lady, who declares she heard Mrs. Hughes bid her daughter go into the kitchen, and take care of the child. — and she went accordingly : soon after this, 1 saw her in the passage. The parties, I understand, are beginning: to work upon those they consider their enemies by piece-meal ; but they shall neither make a tool, nor a fool of me, in this very absurd business. As to voluntary oaths, they never appear to me to rank in the first order of evidence ,• and the case must be bad indeed, where they are offered as substitutes for facts ; it looks as if the parties had so involved themselves in the gulph of credulity, that to return were worse than to go on. 1 am, Gentlemen, Your's, &c. Jno. Turmeau. Bold'Sireet, Jan. 22, 1818. To (he Editor of the Liverpool Saiurday's Advertiser. Sir, As the extraordinary powers attributed to Miss Margaret M*Avoy of this town, have lately at- tracted the attention of the public in an uncommon degree, permit me to send you a fact which has lately I have reason to thiuk Ut. Dale's application to Mr. Turmeau, wjis not suggested by Mrs. Hughes or Miss M'Avoy. 21 oceured, and which, I think, must silence the scepticism of the most incredulous. Two ladies of this town, whose habits of rigid veracity and cautious inquiry are well known, and whose names will be left with your publish- ers, in order to satisfy any doubts which may arise, went lately to the house of this phenomenon, impelled by that curiosity which has now become universal. Fortunately Miss M's marvellous powers, which are known to be sometimes fluctuating and capricious, were that day in their highest perfection, and the following experiment was accurately tried. One of these visitors stood behind the young lady's chair and pressed down her eye-lids with both her hands, so closely that it was a physical im- possibility for a single ray of light to enter. 1 may here remark that no method of closing the eyes by any sort of covering that can be devised, is half so eJBfectual as this, for obvious reasons. The other lady then took up a printed book of sermons which was lying in the apart- ment, and which appeared to have just come in from the bookseller's, as the leaves were not yet cut open She opened it in a place where the leaves had been uncut, and placed it before Miss M'Avoy, (her eyes still closed as above described), who read several lines in it without hesitation. The lady then took a written note out of her pocket, which had been received that morning, and Miss M. also read that without any other difficulty than what arose from the badness of the hand writing. This experiment, which can be ascertained on oath, seems so decisive as to the power possessed by Miss M. of reading by the touch alone, that I am not aware of any possible way in which it can be controverted. I am, &c. your's, T. S. M. Rev. E, Glover's Letter to Dr. Renwick. Dear Sir, You have so frequently solicited me to give you my observations upon the extraordinary case of my friend Miss M*Avoy, that I can no longer withhold them, and must apologize for not having com g8 phed with your request earlier; but my great occupa- tions did not allow me time. X cannot too much applaud the zeal and perseverance you have manifested in the investigation of this most important case ; and 1 will add the candour with w^ich you have conducted it. It is a case, which for the pub- lic information, or for the public good, ought to be thoroughly investigated, and the result authentically substantiated. Under this impression I have been glad to find the opinion, which yoy and I entertain, has been warmly opposed, and objecfions raised. This has given us the opportunity of re-considering the grounds on which we originally founded our opinions, has suggest- ed to us experiments, which our own conviction would have thought unnecessary, and thus given us a confi- dence in our opinions, which, without such oppo- isition, we should scarcely have dared to entertain. For my own part I do not hesitate to declare uncondition- ally, my firmest conviction that she is perfectly blind, and possesses a tact which enables her to read, distin- guish colours, &c. &c. It will be unnecessary to enu- merate the details which have brought my mind to this conviction. But I will say it is a conviction I cannot get rid of, without giving up the evidence of all my senses. It either is true as we have stated, or it is the greatest fraud that ever was attempted to be practised upon mankind; between these extremes in the present instance, there can be no alternative. Now I have so good an opinion of my own underslanding, that if the jatter were the case, I should have discovered it, aided as I have been with the assistance of so many others, enjoying the singular opportunity of seeing her daily, through the progress of thi* extraordinary and long sickness — and having used every diligence, and thought much to bring my mind to the truth on so curious a fact. I will add, that the frieudahip.she has towards me, the confidence you have so frequently observed her to place in me,, the gratitude she feels for the religious instruc- tion she has received from me, the sincerity, with which, under her awful situation, she must converse with one who is preparing her to appear before the God of Truth, all these circumstances put together, must, in my hum- ble opinion, place fraud beyond the possible range of. human delinquency, even if there were an object to be gained by it, which, in the present instancCj there is not^ 28 I have thus sent yon my opinion, aooompanied with a statement of a ffw experiments which my brother and myj^elf made lately. You are at liberty to use all or part of this note, as it may please your- self. I remain, dear Sir, Your's most sincerely, Edward Glover. »ept. 2nd, 1817. I)r. J, Mackenzie's Letter to Dr. Renwick. pear Sir, I oug:ht to have returned you my thanks at an earlier period, for the readiness with which you tnet my request to be prpsent at my visit to your inter- esting- patient, Miss JVl'Avoy, on the 29th of September last ; and to express to you how perfectly satisfied I felt with the full account you and the other Medical Gentle- men in attendance then gav e me of her disease, as well as with the conclusiveness of the experiments made in my presence, to prove the extraordinary powers of touch, developed, in the proirress of its varied symp- toms ; I had but one motive for postponing this expres- sion of .my per.-^onal obligation to yourself and collea- gues, for your attention and liberality of conduct ou that occasion. It was not a scruple of doubt in my mind, as to the reality of what 1 had seen, nor yet a Su';^pieion of imposture on the part of the artless, inge- nuous, unfortunate patient, subjected to trial ; — for the extremes of scepticism and credulity I hold in equal contempt, — as qualities which belong to the weak or the wicked, and are alike fatal to truth : but a desire to see your Narrative of this Uv^ique Case, which was at that time announced to be in the press, and thus have it in my power to satisfy myself as to the whole evidence, statement and facts. That satisfaction is now complete. Your Narrative is before me ; it is just what it ought to 24 be, an honest record of the facts ; and so far as I have been eye-witness to these, I can bear the most unqua- lified testimony to the correctness of its details. Indeed the facts are irrefragable ; no man can deny these, who has seen them, without rejecting the grounds of all hu- man testimony — the evidence of the senses. If such a man there be, his mind is past ail the powers of convic- tion ; his reason prostituted to the sordid passions, or lost in the abyss of universal scepticism. You have abstained from theorising on this case, and in that have shewn your discretion as well as judgment. The Physiologist will undoubtedly consider the facts already established among the most important data that have hitherto presented themselves to his contem- plation, as illustrative of some of the obscurest laws of animal life, particularly those of the nervous system, although their application may as yet be premature. Your patient's case is extremely complicated ; the ra- vages of disease are already extensive ; the indications of cure are uncertain ; the crises that have hitherto taken place, whether favourable or otherwise, appear to have resulted from the determination of morbid action to or- gans so very essential to life, that any material injury to their structure must prove fatal to it; as for example, to the cerebral and abdominal viscera ; consequently, no prognosis can be hazarded in the present state of the case with a shadow of certainty. The disease is still in progress, and your labours by no means at an end. — Proceed in the plan which you have so judiciously adopted, of accurately observing, and faithfully record- ing the phenomena as they arise. You will thus accu- mulate facts valuable to the science of life, and establish a name which neither the malignity of selfishness, nor the philosophy of doubt can ever undermine. With my best wishes for the improvement of Miss M'Avoy's health, and your final success, believe me to be. My dear Sir, Your much obliged, and very faithful servant, John Mackenzie. nth November, 1817. 26 Mr, Samuel Berey^s Letter to Dr. Renwich. Dear Sir, Agreeable to your request, 1 hand you the following particulars, which occurred on my visit to Miss M*Avoy. My mind being previously pre- judiced against Miss M*Avoy, I thought it probable that she might be acquainted with the feel of different sub- stances, to which she had been accustomed ; therefore I inclosed some coloured worsteds in two glass tubes, and sealed them at the ends, with different coloured wax, (which tubes I have sent herewith for your inspection.) I also prepared some green and yellow sympathetic ink, with which I wrote upon slips of paper ; and which writing was invisible when dry. On the 23d of Septem- ber last, I accompanied a party, who had permission to wait upon Miss M'A ; when introduced to her, she complained of indisposition, but seemed wishful to gra- tify our curiosity, and permitted us to try experiments on the power she apparently possesses, of distinguishing colours by the feel. She had the goggles put on, whieli appeared to me to be a most effectual mode of prevent- ing her from seeing, if she possessed any power of that kind, for on previously trying them upon myself, I found the light completely obscured. A printed book was first presented to her, which she tried to read, but could not tell a letter, but after composing herself a few minutes, she told us the colours of our watch seals, by rubbing her fingers upon them; and also told which were glass, and which were stones. I then placed in her hand, one of the glass tubes, (which I had kept in my pocket,) but she could not tell the colours, nor in- deed the substance she felt, as she asked was it a piece of brass? She said the power had left her; however, a short time afterwards, she told the name marked with ink, upon a pocket handkerchief, and the colours of a silk handkerchief, and traced the edge of the pattern printed thereon, with a pin. I then tried her again with the glass tubes, when she immediately told the co- lours contained in them, in the order they were placed, bypassing her fingers over them, and also the colour of the sealing wax at the ends, without the least mistake ; she also told the hour, by passing her finger over the glass of a watch ; she read several v/ords in a book, and 26 ihe directions of several letters, and told the colours of our coats, by feeling the cloth. I gave her a blank slip of writing paper, requesting her to try if she could read the writing upon it, but she said she could not feel any. I then gave her one of thfe slips fi^rote upon with sym- pathetic ink, she said there was writing upon it, but it was so extremely faint, that she could not make it ou|, but she found out one letter, which she called T — I marked the part where she said the letter \Vas, and when I return- ed home, on warming the paper, I found the letter was /, a mistake easy to be made, the letters being so much alike. Sev^eral of the above experiments were repeated, with the same result, her eyes being covered with a silk hand- kerchief, instead of the goggles. In these experiments, I am tjertain that Miss M'Avoy was not prompted by any person, nor do I think it possible that she could have any assistance from her eyes. Mr. Bainbridge^and Mr. John Leigh, werie present when the above experiments were tried, to whom I beg leave to refer you for any further particulars which may have escaped my notice, and I have no doubt but they will confirm the above statement.

Dear Sir, The inclosedt is a correct statement of the experiment with the watch. Yours, &c. S. Peacock. Upton, Juhj2^, 1820. * This Gentleman and Mr. Bainbridge were appointed to examine Miss M'Avoy, by the members of a Club who meet occasionally at the Old Swan, near Liverpool, to decide a wager laid upon the subject of Miss M'Avoy, by Mr. Latham of Wavcrtree, with Mr. John Leigh of Liverpool. It was decided by these Gentlemen agiiinst Mr. i ,atham. ■f Not having seen Mr. Peacock for some time, I wrote to him, inclosing a. printed copy of the K.xperiment he had stated^ to which the above letter is the answer. See page 202. 27 Mr. Evanses Letter to Dr. Renwick. Dear Sir, I visited Miss M'Avoy with Mr. Thomas. You and another gentleman were present. Miss M'Avoy was in bed, and recovering from a severe attack. She distinctly told different colours, and also described some watch- papers. A book was then placed under the bed- clothes, which covered her up to her neck, and opened oh her breast, wheti she read a few lines with her fin- gers. When the book was withdrawn, the words were found correct. On this occasion I placed under the bed-clothes, without the possibility of her seeing even what I conveyed there, a watch-paper of variegated colours. She distinctly, and to our astonishment, named every colour. A book was placed in the same situation, and with her fingers she read a line or two, which on examination we found to be correct. Wm. Evans, Surgeon. Marble- street^ Liverpool. August 7, 1820. The Rev. H. Brewer's Letter to Dr. Ren^ick. Dear Sir, In answer to your inquiries respect- ing Miss M'Avoy, I am happy to inform you that since my first acquaintance with her, which took place in April of last year, and which feontinued to the time of her death, I constantly experienced the greatest can- dour and frankness of disposition. Indeed from all that I could discover during my frequent visits, I con- ceive that she was utterly incapable of every species of deceit and imposition. With vei-y great respect, I remain, dear Sir, H. Brewer. Edmnnd'Btreet, 2ith August, 1820. 3Iade upon this Case before Death, I SHALL make a very few observations upon the foregoing case ; and, until a termination of the disease, under which Miss M'Avoy labours, which may be esteemed decisive, takes place, I shall remain at my post, attending to it with all due care, that the public may ultimately be in possession of those facts which may tend more fully to elucidate It. I have already stated that from the history of the case, I was of opinion that compression of the brain actually existed at the time of my first visit in June, 1816 ; that convulsions and even blindness might be reasonably expected to ensue. Indeed it is probable from double vision having been observed three years before this period, that the optic nerve was not at that time in a perfect state of health ; and from a very early age the eyes had been subjected to repeated inflammation, and consequent weakness. '^he disappearance of the oedema from the lower ex- tremities, the scarcely perceptible fluctuation in the abdomen, the increase of pain and throbbing in the head : and the giddiness which followed, led me to sup- pose that fluid was collected somewhere between the uiembranes, or within the cavities of the brain. T feel myself justified in this opinion by the authority of Mor- gagni, Bonetus, and other writers, who had examined the bodies of persons, in whom convulsions and death followed the sudden disappearance of dropsical swel- lings. In many of these cases fluid was found in the ventricles, or between the meninges of the brain, in a greater or less quantity, but death generally occurred before the fluid could make its way through any artifi- so cial outlet. The case related by Valsalva, and quoted in the Narrative from Morgagni, of a sheep affected with water in the head, is somewhat analogous to that of Miss M^Avoy ; and it is probable had the sheep not been destroyed it might have been relieved from the ac- cumulation of fluid by its discharge from the brain, through the eroded part of the os Ethmoides, which lies under the mamillary processes, affording in time a free passage from the cranium to the nostrils ; for it appeared the commencement of this erosion of the bone was occasioned by the diseased state of the brain, or by the continual dripping of an acrimonious fluid =^ Doctor Baron, of Gloucester, has given an account of a ease somewhat similar in a child, who died after- wards from water in the brain. He had not an oppor- tunity of examining attentively, the ethmoid bone, but he easily passed a probe through it into the nose, from which passage the fluid most probably escaped, in the sudden manner he has described. t Instances have oc- curred also where artificial openings have been made in the heads of children, affected with hydrocephalus, which allowed of the free discharge of a considerable quantity of fluid. Dr. Baron mentions one instance, in which the tumour had been twice punctured, but the event of the disease had not then been ascertained. Dr. Formby, of this town, attended a patient labouring un- der this disease, in which the tumour was punctured by Dr. Vose, and a good deal of serous fluid evacuated, with temporary benefit to the child ; but it afterwards died. It has been supposed the fluid which passsed down in the case of Miss M'Avoy, might have been collected in some tumour, or hydatid at the back of the nose, or in the gullet ; but I have already said it was scarcely pos- sible a tumour could have existed in that situation, con- taining even any moderate quantity of fluid, without being before perceived by its effects in breathing, or in swallowing ; but nothing of this kind took place. The quantity of fluid discharged, from the afternoon of the 12th to the morning of the 16th of June, 1816, • Sheep are very subject to this disease, and the Shepherds often puncture the tumour if it point externally, and sometimes with success. + Vide London Medical and PhysicalJournal, vol. xxxviii. page 464. 91 must have been immense, as it was passing down into the stomach almost incessantly, so as hardly to allow her time to draw her breath. It might almost be calcu- lated from the circumstance of seven ounces having been obtained at two efforts to expel it in a less space of time than one minute. Indeed, it would almost appear, as if its expulsion from the head, after it first began to flow, had followed its secretion in nearly an equal ratio. The fluid, which escaped in very small quantity, from the nostrils after the two following attacks of convul- sion, was of a more glairy nature than that of the first discharge, resembling in tenacity, colour, and consis- tence the albumen ovi, or the fluid generally observed to be contained in hydatids. The fluid collected in ve- ry small quantity, after the convulsions in Nov^ember, J817, was much the same as that which was at first dis- charged ; and the slight discharge which took place from the ear, the day after her alarm from the chimney tak- ing fire, was similar, from the description given of it, to the two discharges from the nose. Since this period, no fluid has passed from the head that we are aware of. Tumours have appeared in the side, in the neck, and upon the os sacrum, extending to both hips. Fluctua- tion has been repeatedly felt in the latter part ; but the very acute pain which took place upon pressing the tu- mour in the left side, in the slightest manner, prevented us from ascertaining its exact nature, situation, or extent: hut from its subsidence after the discharge of purulent matter with the urine, it may be naturally supposed to have extended to the region of the kidneys. In the last discharge which took place the quantity was much more considerable than before ; the swelling under the clavi- cle disappeared ; that, in the lower part of the back re- mained nearly stationary, except when the discharge from the leg was more considerable ; but the pain in the side was so much relieved she could bear moderate pressure with the fingers, on that part of the tumour, which be- fore did not allow them to pass lightly over it without bringing on much uneasiness. She complained of pain extending from the occiput along the spine, and pressing upon it gave her considera- ble pain, caused her to shrink, and most probably this af- fection of the spine occasioned her inability to walk or stand up erect without support. After the last discharge had taken place, she felt herself so much better, thaj; 32 she was carried into the garden, and remained there for two or three hours at a time, as the weather was ex- tremely fine. She named the colour of two fluids, but not so readily as I have seen her do it before. Was un- covered. Notwithstanding; the fineness of the weather, she caught cold and was attacked with symptoms of Pneumonia, for which she was bled repeatedly ; but, al- though relieved from the more violent symptoms, the cough continued for some time. The catching in the breathing and the convulsiv^e motion of the diaphrag^m became occasionally so violent that we found it necessary to have recourse to vene section more frequently ; and the blood which was drawn generally appeared cupped, buffy, or both. The quantity was proportioned to its effects upon the system. It never exceeded sixteen ounces at one time, but gene- rally only from five to eight ounces were taken away. Sometimes the pulse was full and strong enough, at other times it was weak and feeble, and her general appearance contraindicated its necessity, but we de- pended more upon the violence of the catching in the breathing, and the convulsive motion of the diaphragm than upon the pulse; or even her leucophlegmatic coun- tenance, and she generally was reliev^ed from them after the first or second bleeding, but latterly more frequent and larger bleedings were required before these symp- toms receded. In some instances after taking about six or seven ounces of blood, suspension of breathing came on, the pulse continued to beat freely and fully, but if we allowed the blood to flow for any considerable time after the suspension took place, the pulse very soon sank ; at other times syncope occurred, and some- times as she was losing blood, she fell into a state of insensibility.^ • The distinction between this suspension in the breathing and syncope consists in the circulation being continued in the former and not in the latter. The application of the lightest feather to the nostrils or upon the mouth is not acted upon by the breath, until she is recovering from it, nor is any stain perceptible upon a looking-glass placed immediately over the mouth and nostrils. The pulse is not affected materially when she falls into the state of insensibility, which has most frequently occurred during the latter bleedings, nor is the breath interrupted. The suspension of breathing, s.he says, comes on suddenly, and I am aware only of it having existed by a peculiar twisting *bout the heart, and a gasping for breath as l recover from it. The syn- S3 The degree of debility which sometimes fensued alarmed us, but on the day following the bleeding which produced this elfect, we found her generally better, although these unpleasant symptoms often recurred. After several bleedings the blood became very thin and appeared more like bloody serum than blood. When this was the case, the coagulum was small in proportion to the quantity of serum ; sometimes it was partly fluid, but generally firm enough in consistence.^ When we did not venture to take more blood from her extreme debility, and when the lower extremities were very anasarcous, we had recourse to scarifications, by which means a great quantity of serous fluid passed ofiF, which seemed to answer the purpose of the bleed- ing. When the discharge from this source ceased, the bleeding was occasionally resumed, if the symp- toms above mentioned came on with any considera- ble degree of violence, and she seemed to bear the loss of blood better now than in the more early cope commences with a more general lassitude, and she feels a gradual sink- ing of all her animal powers, until she loses every sensation, and when she recovers she feels that languor consequent upon fainting. The state of insensibility spoken of above, which is neither attended with suspension of breathing nor syncope; continues for a longer period and the pulse heats ; at first she is unconscious of all that has taken place, but before her perfect recovery she has sometimes been aware of what was passing, although she could not always speak or give an answer to a question. I have sometimes supposed the suspension might have acted as sleep in recruiting her debilitated frame, for it certainly appears from her own account «s well as that of her mother, that she has obtamed little sleep for a very long period. • In a case of p1 eurisy, which occurred in my practice lately, I found it necessary to order bleeding to a considerable extent. The patient lost in all 212 ounces; fifty ounces were taken away in the first twenty hours, at two bleedings, and the remainder in the proportion of eighteen or twenty ounces, an the patient could bear it. He had been afflicted four years ago with inflam- mation and abscess of the liver- When I first saw him the fiver was consi- derably enlarged ; the body had a generally jaundiced appearance ; he had passed and was passing per anuni gall stones and purulent matter; was frequently afflicted with cold shiverings and spasms. The first quantities of blood which were drawn, exhibited a strongly cupped and bufFy appearance upon the surface, but the inferior part was of the consistence of tar or treacle. As the bleedings were continued, the blood assumed a more natural appea- rance, but the crassamentum had still a strong butf upon it ; the fluidity was exchanged for considerable tenacity, so that the red part of the blood might be held upon the point of a knife. 1 mention this here as it would appear that the fluidity of the blood in the first instance should not deter one from continuing the bleeding, if, in a chronic case, symptoms indicating inflamma- tion, and jiroduced by accidental disc«»se should occur. 3i bleedings. The catching: and oppression iii the breath- ing made me fear adhesions might have taken place in the cavity of the chest; but the cessation of these symp- toms after the bleedings and scarifications induced me to alter this opinion, and to imagine that some peculiar ir- ritation acting on the nerves, supplying the neighbour- ing parts, was the cause not only of these harrassing symptoms, but of the convulsive affection of the di- aphragm.^ When these symptoms were brought on by attempting to protrude the tongue, it would appear as if the com- munication of the continued nerve of the ninth pair which supplied partly the muscles of the tongue with the eighth pair, the sympathetic, the cervical, and the phre- nic nerves might account for their occurrence. Might we not supposcj also, that the peculiar affection of the sole of the right foot, which, when pressed upon, pro- duced that violent and sudden retraction of it, and that general perturbation of the system, were caused by the nerves of the lower extremities derived from the lum- bar nerves, having through these means, a communica- tion with the numerous twigs from the continued trunk of the sympathetic nerve, and from thence with the brain ? Many of the other symptoms which have occurred in this case, may be explained from a similar connexion, through the immediate nerves of the part, and their communication with the brain. The peculiar powers which excited our attention, have not for more than two years been so conspicuous as to enable us to make any more decisive experiments. Miss M'Avoy employs herself, when tolerably well, in mak- ing different little ornaments in sewing, and in netting. She has occasionally named a colour or read a word^ but comparatively with the powers described in the Nar- rative, her success in these attempts is of little impor- tance. When quiet and tranquil, not exposed to any noise or alarm, and not suffering from any domestic uneasiness, or more than usually severe pains of the • The very irritable state of the brain of this female is demonstrated by the eftect produced by any sudden noise or alarm, which often occasioned ineensibility, or the suspension of breathing to take place. 35 head or side, Miss M'Avoy has felt this power return occasionally, in a slig-ht degree.'^ Whether this diminution of the power be derived from the morbid sensibility which almost constantly exists in the left side and in the spine, and which has occurred sometimes in other parts where tumours have appeared, is uncertain ; but it is surely not a very improbable way of accounting; for it, because we have many instances upon record where the violent pain of one part of the body has diminished the excitement in a more distant part. Is it not probable, therefore, that this peculiar power which appeared frequently to be exercised by the points of the finders, and sometimes by other parts of the surface of the body, in ascertaining colours, &c. should be interrupted, or I may say almost annihilated by this peculiar pain, which is always more or less present, and which is excessively increased by the slightest pressure ? If she were an impostor, and possessed of vision, there is no reason why she might not have continued the imposition to the present moment ; for this pain in the side would not prev^ent her from naming what she saw. Her opponents, indeed, say she could see when she named colours, &c. but now that she can scarcely name them, they may change their ground, and declare her to be blind. t Indeed it appears to me very strong evidence in her favour, that, under precisely similar cir- cumstancesj(abating a few peculiar symptoms which have occurred since the publication of the Narrative) and The surface of her body is sensible to external objects passing over it ; fcnd I have observed her to give me her hand, when I put out mine quickly to take It for the purpose of feeling her pulse, but if 1 presented my hand quietly without covering her hand, it remained in its position until ( took hold of it. The interruption to her breath produced a more violent ef- fect upon her general system, but this action upon the surface of the body would seem to be derived from a similar cause, although in an inferior degree vpon parts not so immediately connected with the principles of life. + An assertion of this kind, I have no doubt will be made, but it will not *^ i ™ in proving that she could see when she distinguished colours, &c. and that she is now blind because she cannot name them so decisively. It is well known that a variety of causes prevented the exhibition of her powers, when in the greatest perfection, and these caus. s certainly acted more rea- dily upon an irritable fibre, and, jiroducing a temporary suspension of them, might lead us to suppose a more violent action in the same habit might still further deteriorate, or entirely destroy this power, which was held upon so ft-aal a tenure. - 36 without any material change in her general character, or in the appearance of her face and eyes, from what has been described, she should possess in so inferior a de- gree at the present moment, and for so very long a period the power which had before so eminently distinguished her, and which had been witnessed by so great a variety of persons during a period of more than twelve mouths, if it were not for some cause of this kind acting upon the nerves, or upon the sensorium, which our limited knowledge of these parts will not enable us to explain more fully. The indurated state of the abdomen and the torpor in the chylopoietic viscera were relieved by the mercurial and purgative medicines ; and they were occasionally useful in the latter stages of the disease. The freqnent bleedings kept the inflammatory symp- toms under, which, if they had been allowed, their full range must have destroyed her long ago. The scarifi- cations were also useful for the same purpose, and in taking away the serous fluid from the lower extremities, they might probably prevent its accumulation in the ca- vities of the brain. OpiM'es generally produced rather a baneful than a beneficial effect, except when given to relieve uneasinesss in the bowels, and even then, if the dose were not very small, she suffered very unpleasant effects from their ad- ministration. She found little benefit from any other medicines which were prescribed. I shall, for the present, desist from hazarding other opinions, as in the narration of this case it has been my chief aim to detail the facts which have occurred ; to ab- stain as much as possible from theory, and to leave the public to draw its own deductions from them. Letter of Robert Harrison, Esq. to Dr. Renwick. My dear Sir, I send yoa a correct detail of the appearances observed in dissecting the body of the late Mis< iVPAvoy, as noted at the time by my old pupil Mr. Udny. I consider myself as bound to be particular in noticin<^ them, not only in compliance with your re- quest, but in the expectation of observing some extraor- dinary deviation from natural structure which might explain those interesting phenomena which this case has presented through the long and painful illness to which you have paid such unremitting attention. I feel it however my duty to observe, that in the many examinations of dead bodies which I have made, I have found very few in which disease had left such slight marks, or in which there was less satisfactory informa- tion gained by dissection. It is totally impossible for me, from the confined data obtained by this observation, to explain many of those unusual symptoms which were manifested during life, and which certainly placed this case in a state of uncertainty and obscurity, which 1 can- not but sincerely regret, have not been so sufficiently cleared by the examination after death, as to induce me to intrude any observation with the view of elucidat- ing a train of symptoms, the cause of which, as well as many other medical and surgical diseases, not only re- main concealed during life, but produce so little change in those organs where they appeared to reside, that, not even a trace is found after death. In reply to your question, " fVhat did I conceive was the cause of death?'' I must observe, that for the fore- mentioned reasons, 1 feel that it would be almost pre- sumption to give a positive answer. As far, however, as my information permits me to speak with certainty, I must say, that I did not notice any organic disease suffi- ent to destroy life. I feel more inclined to attribute her decease to excessive and long continued debility, the primary cause of which I cannot attempt to explain. You, who have watched the case from the commence- 38 ment, can best attempt such an explanation, and to your impartial judg-ment I shall leave the further investi^^a- tion, satisfied that your only wish is to stale facts ex» actly as they occurred, and to draw from them such conclusions as may be perfectly legitimate. I remain, my dear Sir, Your's truly, Robert Harrison. Liverpool, Aug. 10, 1820. 3S OF THE 3Sotfi) of Mi^^ M"^^or), <^tatt^ 20 am 9ii ^Ujjuit, 1820, TWELVE HOURS AFTER DEATH, By Robert Harrison, A. B. M. R. C. S. L. & D. one of the Demonstrator of Anatomy, &c. to the School of Surgery, in Dublin, before Drs. Ren- wick and Jeffreys — Surgeons Thomas, Nairn, Morgan, Loftus, Davidson, and Udny — Rev. Messrs. Brewer and Towers, and several Pupils of the Infirmary. As the body lay exposed on the table, the figure ap- peared to have been formed in good proportion ; the whole surface was extremely pale, having a pellucid ap- pearance, there being no marks of red blood in any part. Clear watery mucus was tlowing from the mouth and nares. No tumour was observable about the neck, chest, or abdomen. The spine, viewed posteriorly, was straight and without deformity. Several hsemorrhoidal excrescences protruded throu{>h the orifice of the anus, bnt did not appear in a state of inflammation. The lower extremities were remarkably swollen from anasarca, wiiioh had so distended the integuments about the pel- vis, as to give that region an appearance of preternatural breadth, and had increased the size of the legs to a pro- digious degree. A quantity of fluid was escaping from incisions of the cuticle, made before death, a little above the ankle. We commenced the dissection by examining the con- tents of the cranium, in exposing which, we remarked, that the scalp was very easily detached from the bone, and no blood-vessels appeared during the separation. The cranium itself appeared unusually white and po- lished ; the sutures were strongly united, and in some parts almost obliterated. The sagittal line did not di- vide the OS frontis, as it most frequently does, in the female at the age of the present subject. 40 The bony arch being separated by a circular incision with the saw, great difficulty was felt in detaching it from the dura mater, the connection being remarl^abiy inti- mate. The internal surface of the skull bore the im- pressions of several large vessels running in all direc- tions, some of which were deeply furrowed in the bone, which appeared very thick and strong, and felt extreme- ly heavy, so much so, that had we met with it under dif- ferent circumstances we should have considered it as belonging to an adult male subject. No unusual appearance was remarked on the outer surface of the dura mater. We saw none of those emiuen- cfes called glandulae Pacohioni, either on the membrane, or in the longitudinal sinus, the walls of which we ob- lerved, were thicker than ordinary; the caliber of the canal was of the usual dimensions. On raising off the dura mater, we perceived the arachnoid membrane, where it covers the hemispheres of the cerebrum, to be white and dense in some parts, and separated from the surface of the convolutions and their interstices, by an opaque gelatinous eifusion. This appearance was most in the vicinity of the longitudinal sinus. The pia mater appeared pale, as also the whole sur- face of the brain ; very many large vessels were distinctly ramified upon both sides, but they contained no blood, and the entire aspect impressed us with the idea, that the brain was less vascular than usual. The organ ac- curately filled the inv^esting membrane, and to the touch it was of the usual firmness. On cutting each hemis- phere to a level with the corpus callosum, we remarked, the almost total absence of blood-vessels : we did not see any of those red dots which commonly appear so nume- rous in a division of medullary or fibrous substance ; but the centrum ovale appeared of a milk white, unstained by any vascular appearance. The fibrous structure of the corpus callosum, was unusually evident, and the whole felt of a firm consistence. The lateral ventricles were next opened. In their ca- vities a small quantity only of fluid was observed. The choroid plexus was very pale, biit could be expanded, so as to shew its natural tissue free from any of those changes in structure so commonly observed. The sep- tum lucidum was very strong and the various eminences throughout the whole extent of these chambers, appear- 41 ed in a perfectly healthy state, and in prosecuting the dissection through the different laminae in the usual or- der, down to the third ventricle, we were all satisfied that we do not commonly see their several parts so dis- tinctly marked, and so exempt from disease. In the third ventricle, the commissura mollis was very strong and broad ; the different openings from their cavity were free and distinct, and the pineal gland had nearly the same appearance as in the young subject. On di- viding the tentorium cerebelli, the whole surface of the cerebellum presented the same pale aspect as the cere- brum, but in other respects was healthy. On exposing the canal which leads from the third to the fourth ven- tricle, we found the cavity to be of its ordinary dimen- sions ; but on its posterior wall we remarked some unu- sual appearances; here the surface was not smooth, white and polished, as in other parts, but appeared rough and dark coloured ; this was owing to a small fungus-like excrescence, which projected from the back part into the cavity; it might be compared to a small portion of fur, it did not appear vascular, was very soft, and could be easily torn off from its connections; it was not unlike a small portion of coagulable lymph, effused in inflammation on a serous surface. On making an incision into the hemispheres, they were of the usual ap- pearance. We next proceeded to examine the base of the brain, and the course of the cerebral nerves. The olfactory appeared healthy; behind these the union of the optic nerves on the sphenoid bone was seen smaller than usual, very thin and flaccid, as if the nervous substance tlid not fill the investing membrane, a little pale fluid being between the nerve and its tunic. The nerve, also from this to the orbit appeared very thin snd flat, more particularly the left, which was peculiarly flaccid and delicate ; traced back to their connection with the Tha- lami Optici and Tubercula quadragemina they appeared as usual, broad and flat. The pituitory gland, and Infundibulum were of natural situation ; and all the ce- rebral nerves presented a healthy appearance, having their usual attachments to the brain, and taking their usual course ; all other parts on the base of the brain appeared perfectly healthy, and the same remark passed 42 on looking; on the divided surface of the spinal marrow, which was cut in the cervical region. On opening the orbit we observed them to contain much loose and watery adeps ; the muscles of the eye^ balls were very weak and pale ; the nerves were all distinct, and the optic appeared of the usual size and consistence ; on cutting- across both of these nerves, we did not observe the red spot pointing out the situation of the arteria centralis Retinae, so commonly seen in this incision. On dissecting the eye-ball itself, all the parts were distinctly seen in this beautiful organ, perfectly free from disease. The lens and its surrounding trans- parent fluids ; the retina and its investing tunics, with the pigmentum nigrum, were satisfactorily seen in both eyes On the retina the punctum aureum was very bril- liant ; we could not see any of the branches of the be- fore-mentioned artery, either on the retina or piercing the vitrious humour. THORAX. Having elevated the anterior boundary of this cavity, a considerable quantity of loose adipose substance was seen covering the pericardium in greater abundance than is usual at the age of this subject. The lungs im- mediately collapsed very much, they being of a pale grey colour, and of their usual spongy emphyseaiatous feel. No disease was observed in their surface, or in their substance ; and no adhesions existed between the pleura pulmonalis and costalis. In each pleura about four ounces of reddish serum were contained. The pericardium was slightly distended, and fluc- tuations could be distinctly felt ; on opening it, three ounces of a straw-coloured fluid was discharged, and the surface of the heart exposed. This organ had much adeps upon it, and felt extremely flaccid, and looked very pale. The serous membrane covering it was rough in spots, particularly near the apex, where many small white patches were obvious, and were pro- bably the effects of inflammation once acute, but long since subsided. The interior of the heart was natural, and the diff'erent valvular apparatus perfectly uninjured. The right ventricle was very weak; and the left, though Uiicker, was very pale; both contained long coagula 43 of blood. Aroand the semilunar valves of the Aortflj slight traces of incipient disease were noticed. ABDOMEN. In this cavity, no appearance of disease was observ- able, in the peritonasum, stomach, or spleen. The liver was rather large and soft, of a pale yellow colour ; there was no disease in its substance. The gall bladder was full of dark coloured bile. The pancreas was healthy ; also the mesenteric glands, the intestines, both small and lar^e were distended with flatus. The kidneys appeared very large, particularly the right ; they were both pale, and contained more adeps internally than is commonly observed. The several capsules were as usual. The ureters and urinary blad- der were perfectly healthy. The uterus was very small : both ovaria were diseased, being enlarged to the size of a hen's egg^ and containing an infinite number of small transparent hydatids. On exposing the vertebral column, by removing the viscera and muscles in front of it, the whole was found strong and free from disease ; the nerves also passing out from it were of the regular yize and colour. It was not deemed necessary to examiue the spij:i«l «anaL 45 3Iad€ after the Death of 3[tss M'Avot/, The appearance upon dissection, and the detail of the symptoms in the Narrative and Continuation of this Case, will confirm the general position laid down by the anatomist, who minutely examines the different parts of the human body, that the seat and cause of disease are frequently not found out by dissection ; and that the cause which produced it is often very different from, and incongruous with the symptom expressed. The Physiologist must therefore expect to find this lesson often repeated to him by the Anatomist. It proves how easily he may err, when he wanders into the field of conjecture. But still he may console himself in the re- flection that sometimes enough may be discovered to ac- count for many of the symptoms he has stated: and at any rate he has performed a duty in detailing circum- stances of a curious nature which he has seen, and which other individuals have witnessed as well as himself, whe- ther they can be accounted for or not. Bichathas said, that physiology deprived of the light which anatomy gives, proceeds only by chance. It was for along time only nourished by the flights of genius : a vain display which the imagination had decked out, but to be overturned by the breath of reason. The Physiologist deeply skilled in anatoiny does not always obtain a proof of his reasoning being correct, when he even makes the research with his knife. Can we then wonder, that in an object so complicated, and so minutely constructed as the human frame, that it should be difficult to discover the origin of disease, or the im- mediate cause of death ? And more particularly when that disease may be seated in parts, in which their for- mation would lead us to say, thus far thou shalt go 46 «nd no farther. Yet, that reason which has been im- planted into the mind of man, would not have been given to him, had it not been intended he should exert it for his own benefit, and for that of mankind in general. AU though bounds seem to be set to our obtaining that inti- mate knowledge of the structure and offices of the brain, and of the diseases dependant upon its derangement ; yet it r/iay not be impossible of attainment, when we consider the rapid advances which have been made in our knowledge of some of the component parts of the human body ; of the peculiar actions of each, and of the nature of the fluids secreted upon the various surfaces of the different membranes which are subservient to life. ' However long it may be before we acquire this infor- mation, or whatever failures may occur to paralyse our efforts in the pursuit of it, it is yet our duty to continue the inquiry with all the perseverance in our power ; to remark symptoms ; to give openly to the public our prac- tice and opinions, and we may then content ourselves that, if we have not obtained, we have at least deserved success. I shall now endeavour to follow Mr. Harrison in his dissection, and to draw from it those inferences, which may throw some light upon the particular symptoms elicited in this case. The general appearance of the body was leucophleg- matic, or rather bordering upon that of tallow. The integuments about the pelvis were so distended as to give preternatural breadth to that region, which Mr. Harrison attributed to anasarca. When the incision was made upon the breast I did not observe any material serous exudation ; nor was there any fluid of moment in the abdomen, but it was remarked there was more adipous substance than usual at the age of this subject. The fluctuation which appeared to me and others, filling the space between the last lumbar vertebra, the middle of the sacrum, and the hips, did not seem (be- fore death) to be so diffused, as in general anasarca, but to be in some measure confined to the parts above-named, and to be more deeply seated. Upon examination after death, this fluctuation had become more diffused, and its former local situation was nether perceptible to the sight nor to be felt by the touch. From the observation Miss M*Avoy made, that when ^ke discbarge from the left I^g was more abundant, the 47 swelling above mentioned became less, it appeared to me there might be some communication between them The anasarca of this leg had disappeared for some time before this deeper seated fluctuation was noticed ; and from the appearance the discharge had, when collected upon the bread and milk poultice, I thought it very si- milar, in consistence and colour, to the fluid subjected to Dr. Bostock's analysis : this colour mig^ht however have been caused by the union of serous fluid with the milk used in the poultice ; for upon a deep incision being made into the back of the leg after death, a considerable quantity of fluid escaped, which was not tinged in this manner, but had rather a darker appearance than tho serum of the blood. Under the circumstances it was not possible to exa« mine minutely, the spinal colurnn, so as to see if there vv^ere any outlet from which this fluid could have passed down, where the fluctuation was felt upon the sacrum and between the hips Dr. Baillie has lately observed, that if there be serous effusion between the membranes of the brain, a portion of the serum may fall into the cavity of the the cavertebralis, and press upon the lower part of the spinal marrow. In this case we might easily ac- count for the loss of power in the lower extremities, if such pressure existed; but if necessary we might have recourse to the state of the brain itself, where the effects of injury were certainly evident. In paralytic affec- tions often no trace appears in the brain to account for them ; and yet, when they occur in a part of the body, or in the extremities, and cannot be traced to any cause existing in the immediate neighbourhood, or from local injury, we have no other resource but to look for the cause in the brain. Mr. Harrison did not observe any opening internally ; but w^e could not break through the bony coverings, so as to examine if there were any outlet by which the first fluid had escaped. Its dis- charge certainly took place, relieved the convulsions, and a great quantity passed down into the stomach ; was thrown up again, and a part which had not entered the stomach on the fourth day, was obtained, and after- wards analyzed by Dr. Bostock. After the death of this patient, it was observed that fluid came down the nose and out of the sides of the mouth, as she lay upon her back ; but when turned upon her face a very considerable quantity, which Mr. Har- -^4_ 48 rison calls a clear watery mucus, was flowing from the mouth and nostrils. I regret we did not preserve some of this fluid ; for it was in much greater quantity than usually occurs, and appeared very much to resemble that which was obtained after the first attack of convul- sions. It might have been the more fluid part of that eflfusion which had taken place upon the arachnoid membrane, the traces of which were only observed by a gelatinous appearance, which separated the brain and its convolutions from a more close connexion with this investing membrane. It may be remembered also that a discharge took place through the nose and ear, of a similar consistence to that which was observed upon this membrane. It is also more reasonable to suppose this to have been the case, than that it should have been secreted in so great a quantity upon the mucous mem- brane of the nose, because a peculiarity was observed in this female, that she rarely blew her nose; and it was therefore improbable, that so great a quantity of fluid could have been secreted upon its surface. Her mother informed me that if she were subjected to any domestic uneasiness, a discharge now and then took place down the nose, which was of so acrid a nature, as to excoriate the adjacent parts; and it would seem not to have been derived from the mucous membrane, but from a higher source, even the brain, its ventricles, or investing mem- branes. I have already noticed in my observations pre- vious to the death of Miss M'Avoy, that from obtaining, on the fourth day after the convulsions seven ounces of this fluid in the short space of one minute, the quantity eflused altogether must have been immense, and it must have been liberated from the brain nearly in a ratio with its quantum of secretion. To have contained this quan- tity the brain, as well as the bones of the skull must have been distended so as to have met the exigency. This, however, could not happen in this instance, be- cause death must have ensued, by the compression this accumulation of fluid would have caused upon the brain if it had not found an outlet. From the compacted state of the sutures also, the cranium had become so firmly united, as to render its extension, without absolute frac- ture, impossible. The anasarcous state of the legs and thighs had been observed before at different times, and it sometimes subsided. Previous to the first attack of convulsions, ^ the anasarca of the lower extremities suddenly disap- peared.* Upon my first visit Miss M*Avoy complained of vio- lent pain in the fore and back part of the head, with a throbbing^ and beating sensation. The vessels of the tunica conjunctiva were filled with red blood, but she suffered very little uneasiness from the action of light. She was so much affected with giddiness, as to stagger in walking across the room. With the left eye she could scarcely distinguish any object; and with the right, for several days previous to me seeing her, every object at a distance appeared white, and those which were near double. It would seem therefore, that this sudden dis- appearance of the swelling from the lower extremities had caused these symptoms; and we might reasonably draw the inference of a metastasis having taken place, and that this fluid had been diffused between the men- inges, or deposited in the ventricles of the brain. Convulsions certainly did occur, and had the brain not been relieved by the discharge of this fluid death must have ensued on or about the 12th of June, 1816, as we left her in a most exhausted state, and without a proba- ble chance of recovery. This recovery was however, for the present obtained, and apparently, in conse- quence of this discharge having taken place at the time and in the manner mentioned in the Narrative. * I have stated this translation of serous fluid not to be a very uncommon occurrence. Indeed, m^ny cases are upon record, in which the fluid has sud- denly disappeared from one part only to be deposited upon another, and some- times to be absorbed and dissipated altogether. Instances occur, where more deleterious fluids have been removed from their excretive organs; even pus has been absorbed suddenly, and left hardly a trace- of its previous existence. The two following instances will corroborate this opinion: — Mr. Udny in- forms me, that Mr. Wilmot, of Dublin, in his Lectures, mentions the case of a gentleman (to whom he was called in,) who had been intoxicated the preceding evening. He complained of great pain in the abdomen, with a wish of passing his urine, but he was unable to do so: the bladder was distended to a very unusual degree. Mr. W. went home for a catheter, and returned in half an hour, when he found him in a state of coma: the tumour of the abdomen had subsided, and in passing the catheter into the bladder, it was empty. He died shortly after, and on dissection the ventricles of the brain were found full of a fluid of a curious smell and ?"ppcarancc. A gentleman, when attendiii?^ his medical studies in London, was scarcely able to weilk, in conijcquence of a bubo which had suppurated, was nearly as big as his fist, and the skin appeared of that colour and thinness, he thought it must burst in the night : bat to his astonishment, in the morning, not a trace of it remained, except that the skin was a little more wrinkled on the one side than on the other t He continued the course of medicine he wa^ before pursuing, arid never felt any inconvenience afterwords* 50 iThe different attacks of convulsion were several timejf relieved, either in a similar way ; by the discharge of a g:elatinous fluid through the nose; by profuse perspira- tion ; or by the appearance of the catamenia. Once a slight discharge took place (of a gelatinous fluid) from the ear. Had she been permitted to survive a little longer, it \s probable one of the former results might have happened again ; for the legs and thighs were very much distended with serous fluid ; and although the scarifications caused at times a very considerable discharge, it was not con- stant, and a part of it during the period when it ceased, might probably have been taken up by the absor- bents^ whicTi being overloaded by this additional supply, would naturally pour out through the medium of the ex- Lalants this superfluity into some of the cavities; and as it would appear this circumstance had taken place be- fore, either in the ventricles, or between the meninges of the brain, it is more reasonable to suppose that it would be deposited again upon these, rather than upon other surfaces. Death, however, seized its victim before this event could take place ; therefore, we have only the appearance of the white spots upon the arachnoid mem- brane ; of the gelatinous fluid between the convolutions and interstices of the brain ; the discharge of fluid from the nose and mouth after death, and the circumstances which had occurred upon the cessation of the different convulsions to support the opinion originally formed, The attachment of the dura mater to the cranium, the very strict union of the sutures, and the strong im- pression of large vessels running in all directions upon it, some of which were deeply furrowed in the bone, shew that at one time or other strong action of the ves- sels had existed. The cranium itself was very thick and strong ; felt extremely heavy, so as to give it the ap- pearance of belonging to an adult male subject. The dura mater was not altered in its structure. The glan- dulas Pacchioni were not seen on the membrane, or in the longitudinal sinus, the walls of which were observed to be thicker than ordinary.'* * It is curious that these glands were not visible. In what manner can we account for their disappearance, or extinction : their uses are not certainly Inown, and many physiologists think them oi' little imiwrtance; yet tliey are alqiost always found on the insidcj of the Longitudinal siuus, and appear io he connected with the o])ening of the veins: they generally apixfar of a rieshy co- lour, projecting like iiiu:ipLc:s, or the efjgs of silk worms. 61 Wherever a thickening of parts takes place we must suppose disease to have existed ; and, from the walls of this sinus being thickened, it most probably has arisen from increased vascular action. I have already spoken of the appearance of the arach- noid membrane. The pia mater appeared pale ; also the whole surface of the brain. Very many large ves- sels were distinctly ramified upon both sides, but they contained no blood, and the entire aspect impressed us with the idea that the brain was less vascular than usual. In ditferent cases, I have seen where patients have died of hydrocephalus, particularly where they have been re- lieved, and the disease has recurred, there is less ap- pearance of vascularity, than where it terminates more suddenly, This patient was bled to a considerable ex- tent; at first in small, but latterly in larger quantities, and the very last bleeding shewed signs of the necessity of meeting, with the fullest effect, the urgency of the symptoms. This blood was firm, tenacious, and mig-ht be held for a considerable time upon the point of a knife without shewing any marks of a weakened cohe- sion of its particles. Indeed in the early bleedings, the blood appeared sometimes much less tenacious. Since the dissection some observations have been made, I understand that the bleedings may have caused this blanched appearance of the vessels of the brain, and that we have pursued this plan of treatment to too great an extent ; but I am satisfied if it had not been particu- larly attended to, she would have long since died of the consequences of inflammatory action. Her own feel- ings, the amelioration generally of the symptoms after each bleeding, and my own experience of the benefit resulting from the practice in this case, will justify me in the means I pursued. In the latter bleedings, the force with which the blood rushed out of the orifice, ev^en after the fillet was taken off, is a poof that the stitch in the side produced violent action in the heart and arteries ; and this increased action must also have been transmitted to the veins. The feel- ings of the patient herself, as to the relief afforded, is the best comment upon the propriety of the practice. The brain and cerebellum were generally healthy in their appearance, excepting that they had a paler as- pect upon their surface, and through their substance 62 from th^ vessels not beiDg- so filled with red blood as is usually seen in subjects where no long-continued affec- tion of the brain has existed. The first, second, and third ventricles appeared in their usual state; but the fourth ventricle shewed marks of disease. This alteration of structure was probably owing to the cause Mr. Harrison assigned, viz. " inflammation." Could serous effusion have been produced by this cause, and of such an amount as to have accounted for the dis- charge of the fluid, which is supposed to have passed down from the brain into the stomach, through the nose and ear : and to have made a lodgement between the hips, after passing down the vertebral theca : or, was it only derived from the effusion caused by inflammation of the arachnoid membrane, the remains of which were seen in the gelatinous substance which appeared in the convolutions and interstices of the brain? In whatever way it was produced, it is certain some fluid existed, was passed down into the stomach, through the nose and ear, and was felt by ditix3rent individuals between the hips. The olfactory nerves had a healthy appearance ; behind these the union of the optic nerves on the sphenoid bone was seen smaller than usual, very thin, and flaccid, as if the nervous substance did not fill the investing membrane, a little pale fluid being between the nerve and its tunic. The nerves also from this to the orbit appeared very thin and flat, more particularly the left, which was pe- culiarly flaccid and delicate. On opening the orbit, much loose and watery fat was observed. The muscles of the eye-ball were very weak and pale. The nerves were all distinct, and the optic appeared of the usual size and consistence, but on cut- ting across both of these nerves, the red spot pointing out the situation of the arteria centralis retinae, so commonly seen on this occasion, was not observed, nor were any of its branches discovered either in the retina or piercing the vitreous tumour. The more than usual quantity of adeps might be accounted for, from the cir- cumstance that there was generally a predisposition in this subject to theaqcumulation of fat, which might have arisen from the quiescent state in which the body was kept by her inability to move about. In this particular 53 part of the body, its loose and watery appearance might have been caused by the diminished excitement which a state of blindness would naturally produce. Had sight ex- isted, and the motions of the different parts of the eye been properly exercised, thissuperfluity would have been necessarily removed by the quicker action of the ab- sorbents. The muscles of the eye-ball were very weak and pale, which has been supposed to have arisen partly from the loss of blood, but when we consider the general relief afforded by the bleedings, (which were never greater than to meet the exigency of the case) the state of the blood, with respect to its firmness and tenacity, in the very last bleeding, we can hardly attribute the state of these muscles to the detraction of blood ; for if this had been the cause of their weakness and paleness, we might have expected to have seen more imperfection in the coats and humours of the eye, as well as in the muscles ; instead of which, the membranes, humours, &c. of this beautiful organ, even to the punctum aureum of Soem- mering, were seen in a perfectly healthy state : they could not all have existed in this state without a due distribution of blood ; but in what way could the retina have received a proper supply of blood, if its own artery were obliterated? For the purpose of its mere existence as a membrane, it might be supplied with sufficient blood, by some small twigs from the ciliary arteries ; but for that of vision, probably more would be required, to give the minute branches of the nerve their proper nou- rishment and sensibility. It appears to me, that the weakened action of these muscles arose from the loss of vision, which prevented them from being exercised in a proper manner. If a muscle be not brought into action for a long period, it will become incapable of producing any of those moti- ons which were natural to it ; and if an attempt be made to recover the tone it has lost from disuse, a strongersti- mulus will be required to bring it into action, and it must be employed cautiously and frequently, to restore it to its pristine vigour. The effects of convulsion were per- ceived in this peculiar case, when it gave additional sti- mulus to these muscles, and excited them into extreme action; but when it ceased, the motion of the eye-balls were probably still more weakened, because a too sud- H den and strong excitement produces a great degree of debility afterwards. The functions of the retina could not be performed by the nerve alone, because the nerves depend as much for support upon the circulation of blood, as the blood- vessels depend upon nervous influence for the con- tinuation of their action. It has been observed that the pupil of the left eye had fewer motions than the right, and we find, from the dissection, that its nerve was peculiarly flaccid and delicate. The opponents of Miss M'Avoy, may of course, reason upon this general healthy state of the eyes, as a proof that she possessed the power of vision ; but they must at the same time re- collect, that in amaurosis little alteration sometimes ap- pears in the structure of the eye, its membranes, coats, humours, or vessels. The optic nerve may not appear altered in its structure, upon dissection, whilst its powers were allowed to be so totally inert during life as to produce blindness. If, however, in addition to the obliteration of the central artery of the retina and its branches, we find an altered structure of the optic nerves at their union upon the sphenoid bone, as de- monstrated by their smallness, thinness, and flaccidity ; as if the nervous substance did not fill the investing membrane ; a pale fluid intervening between the sub- stance of the nerve and its tunic, which must ncQes- sarily press upon that substance ; and the nerves af- ter their division from this point to the orbit, being very thin and flat, we cannot doubt that these appearances m'ust have been caused by disease, and that of no small moment. If we consider this case in all its bearings, the symp- toms which preceded Miss M'Avoy's blindness ; the con- vulsions which followed ; the discharge of serous fluid which removed these convulsions; her peculiar powers, asexhibited in situations where sightcould have no influ- ence ; the insensibility of the eyes upon exposure to the rays of the vivid sun, or to the most brilliant colours of the solar spectrum, thrown suddenly, and in all direc- tions upon them ; a similar insensibility to the sudden ap^ plication of any pointed, or other instrument ; her per- fect indiflference upon a pistol being suddenly pointed at her; the want of irritability in the cornea or ball of the eye, when a probe or other substance was pressed upon. 55 or passed over it and the pupil, we shall hardly require the aid of disease to prove her blindness. From these considerations I think a strong case will appear in support of our opinion that Miss M*Avoy was blind from the time specified in the Narrative, to th« period of her death. THORAX The principal appearances in this cavity, were a consi- derable quantity of loose adipose substance covering the pericardium in greater abundance than is usual at the age of this subject. The lungs were healthy. There was not the least ap- pearance of disease in them. No adhesions existed be- tween the pleura pulmonalis, and costalis. I have stated in my remarks previous to her death, that the catching and oppression in the breathing made me fear adhesions, which so commonly are seen in the dissection of dead bodies, might have existed in this case to a serious extent ; but the cessation of these symptoms after the bleedings and scarifications, induced me to al- ter this opinion, and to imagine that some peculiar irri- tability acting on the nerves, supplying the neighbour- ing parts, was the cause not only of these harassing symptoms, but of the convulsive affection of the di' aphragm. This opinion is confirmed by the dissection. The symptoms of pneumonia which occurred in Au- gust last, induced me to prescribe bleeding repeatedly, and it has been often supposed (by the intelligent men who saw her labouring under the effects of this disease) she would have borne still larger bleedings at the time. It was attended with a very harsh cough, which conti- nued for a considerable time after the other symptoms were relieved. In this case, however, no appearance of former disease remained on the surface of the lungs, or in its substance : yet a larger quantity of fluid appeared in each cavity of the chest than usual, which might have been produced by exudation upon a serous surface from inflammation of its membrane. It will be the business of more able anatomists than 56 myself, and who have had more opportunities of inves- tigating- the seat and cause of disease, (from dissection,) to determine, whether by the active means which were used to relieve inflammatory action, it might not be pos- sible to prevent these appearances of diseased surface which commonly occur where these means have not been used in proper time. The same observation will apply also to the disap- pearance of all the tumours, previous to the death of this patient, except that between the hips, which after- wards gave the appearance of preternatural breadth to them. The peculiarsymptoms mentioned in the Narrativeand in the Continuation of this Case, would lead me to sup- pose we might trace the cause of many of them from the state of the heart and pericardium. The fluid con- tained in the pericardium was about four ounces: Mr. Harrison says only three, but about an ounce was lost in pouring it out from a cup into a phial, and nearly as much was left in the cavity. The quantity taken to the Infirmary, was exactly two ounces and a half. The ef- fusion of this fluid marks a diseased action to have taken place upon its surface, and most probably from inflam- mation. The accumulation of fat marks a diminution, or a de- ficiency in the active powers of the heart. The appear- ance of the serous membrane covering the heart indi- cated inflammation to have existed, and it particularly shewed itself near its apex. Mr. Harrison supposes this to have long since subsided. The violent stitch she so frequently felt, was indicative of present inflammation, or, at least of diseased structure, which prevented the functions of the heart from being properly performed. The weakness of the walls of the right ventricle, might cause the blood not to be propelled with its usual force, and in its proper quantity, into the pulmonic artery, and from this artery through the substance of the lungs; and this weakened state maj- also account for that peculiar symptom of oppression which was caused by placing the hand so near the mouth as to intercept the breath; because any sudden interruption to the re- ception of atmospheric air into the lungs of so irritable anhabitmusthave the effect of impeding the oxygenation of that blood which is to be returned through the pul- 57 monary veins, into the left auricle, then into the left ven- tricle, and from thence into the aorta and its ramifi- cations. It is impossible to say when this inflammation of th« membrane covering- the heart commenced. In Jane 1816, she complained of palpitation of the heart, and of oppression in the breathing*, but at that time I looked upon these symptoms as dependant upon the enlargement of the liver, and upon the tense and incompressible state of the abdomen. As these symptoms, after the use of mer- cury, were removed in the course of that year, I think it more probable they were symptomatic of the state of the liver and abdomen, than that any active inflamma- tion existed at that period in the heart or upon its invest- ing membrane. The appearances around the semilunarvalves marked incipient disease, which might, at a later period of life, have terminated in ossification. It cannot be decisively known when this inflammation of the investing^ membrane of the heart first commenced, but it is probable it preceded the more violent symptom of catching in the breathing. The convulsive motion of the diaphragm might also have been derived from the same cause. The connexion between the heart and muscles of respiration, independent of any other cause, will account for the first ; and (hat of the phrenic nerve with the heart, will bear me out in the opinion, that the latter symptom originated from this connection between the heart and the diaphragm. The fluid contained in the pericardium most probably owed its origin to the inflammation of the surface of its membrane, and many of the peculiar symptoms might have been caused by the effects of this inflammation. The heart is an organ of that active and important nature, that the least alteration in its structure may lay the foundation of serious disease; and we often see that it proceeds in its course, until it terminate in some hor- rible kind of death. If disease exist in itself, or in its membranes, and that disease be only incipient, it may occasion symptoms of a curious and indefinable nature. Of this kind is the sensation she expressed of a cold ring of iron placed upon the point of the heart,* and of the cold drop of vcater falliug within the centre oi the ring-^ previous to the stitch eoiiuiij^ ou. 58 In what way are these symptoms to be accounted for ? The catching- and oppression of the breathing, and the convulsive afiectiou of the diaphragm, as the lungs were sound, must have arisen from the state of the heart, which however slightly diseased, might have produced these peculiar symptoms through the medium of the nerves communicating from that organ, with the mus- cles of respiration and with the diaphragm. Miss M'Avoy was occasionally subject to palpitation of the heart, and any sudden noise or alarm frequently threw her into a state of insensibility. The first symp- tom may be derived from the same cause which pro- duced the catching and oppression in the breathing, and the convulsive affection of the diaphragm ; or from ner- vous irritability. The latter-effect must have been owing to the peculiarly irritable state of the brain alone. It appears Miss M*Avoy was very backward in her learning ; sewed very indifferently; and had litte acute- ness in her perceptions previous to the discharge of the fluid: but afterwards she learned every thing with ease, sewed very well, and her perceptions were very acute. These circumstances can only be accounted for from some peculiar change having taken place in the state of the braiu» She occasionally exhibited symptoms of hysteria, and some persons, before the dissection, have supposed the convulsions which afflicted her, to have been hysterical, but this opinion does not appear to be correct, as many of them came on without being attend- ed with this disease. Hysteria, is one of the most Proteus-like diseases we are acquainted with ; but Miss M'Avoy seemed to en- deavour to check any disposition to it in herself; and as there were traces found of disease in the brain, we must have recourse to it for an explanation of the cause of the convulsions. The peculiar sensibility of the fingers I have given proofs of; but, it will not be easy to explain in what way it has originated. It was only known to herself about three months after her blindness came on. Could it have existed before? And that, from the circum- stance of her seeing at the time, this power was not known even to herself. Or, is it not more probable that the same cause which produced a brighter intellect, than she before possessed, might have also given a 59 great degree of sensibility to the nerves of the fingers, and of some other parts of the surface of the body ? ABDOMEN. No disease appeared in this cavity, unless we attribute to disease, the pale yellow colour of the liver, its great enlargement, and its softness. I have little doubt the liver had been diseased, and that the frequent use of mercury had restored it to a more healthy state. The general tension of the Abdomen was relieved in the ear- ly period of my attendance, and apparently by the use of the mercury and purgatives. The mesenteric glands were supposed originally, to have been affected ; or, whence these tumours in the Ab- domen spoken of previous to my first visit? It is a curious fact, that no tumour, or vestige of a tumour, was observed in these parts on dissection, because not only from the symptoms, but from the elevation of the tumour above the surrounding parts it did ap- pear to exist, and only subsided upon the discharge of matter at dilfef-ent f}w:es through the bladder. From what cause this appearance of tumour orginated, or whence this matter was derived, will be difficult to ex- plain ; but certainly the former was noticed by different individuals, and the latter subjected to the test of expe- riment, which proved its nature. The kidneys were larger than natural, particularly the right ; were both pale, and contained internally, more fat than usual : the several capsules had suffered no change. Is it probable that the purulent matter passed off with the urine could have been secreted in this organ, with- out lea\ing a trace behind it? The Psoas muscles were cut into, but there appeared no remains of disease. The ureters and urinary bladder were perfectly heal- thy. The symptoms of dysuria and pain have probably been caused by irritation only ; or some marks of disease would have surely appeared. The Uterus was very gmall. Both ovaria were dis- eased, or enlarged to the size of a hen's e^^, and con- tained an infinite number of small hydatids. The state of the uterus may account for the suppression and al- h 60 tered appearance of the catrtmenia ; and it is probable this affection of the uterus, and of the ovaria may have pro duced that variable and unsettled state of the stomach and bowels which so often affected her. The entire case of this female is now before the pub- lic, and it will jud^e how far the appearances upon dis- section may enable us to account for her blindness, and many of the symptoms which have occurred ; and whe- ther the proofs, 1 have adduced, of her possessing pecu- liar powers through the medium of her fingers, are not gufificient to corroborate the statements originally made in the Narrative and which were supported at the time by the evidence of many other individuals.
