Les images suivantes ont 6t6 reproduites avec le plus grand soin, compte tenu de la condition et de la nettet6 de l'exemplaire film6, et en conformity avec les conditions du contrat de filmage. Original copies in printed paper covers are filmed beginning with the front cover «tnd ending on the last page with a printed or illustrated impres- sion, or the back cover when appropriate. All other original copies are filmed beginning on the first page with a printed or illustrated impres- sion, and ending on the last page with a printed or illustrated impression. Les exemplaires originaux dont la couverture en papier est imprim^e sont film^s en commenpant par le premier plat et en terminant soit par la dernidre page qui comporte une empreinte d'impression ou d'illustration, soit par le second plat, selon le cas. Tous les autres exemplaires originaux sont filmds en commenpant par la premidre page qui comporte une empreinte d'impression ou d'illustration et en terminant par la dernidre page qui comporte une telle empreinte. The last recorded frame on each microfiche shall contain the symbol ^"»> (meaning "CON- TINUED "), or the symbol V (meaning "END"), whichever applies. Un des symboles suivants apparaitra sur la dernidre image de cheque microfiche, selon le cas: le symbole — ♦► signifie "A SUIVRE", le symbole V signifie "FIN". Maps, plates, charts, etc., may be filmed at different reduction ratios. Those too large to be entirely included in one exposure are filmed beginning in the upper left hand corner, left to right and top to bottom, as many frames as required. The following diagrams illustrate the method: Les cartes, planches, tableaux, etc., peuvent etre filmds d des taux de reduction diff^rents.

These consideratioi.s .see.n to me conclusive aga'Mst the ilexry that the emotioud sate is depemlent upon the mental image, and the grounds given abuve seem also to establish the position that the state of the sexual secreting glands is the rea> determining cause of (he Amotion. This being the case we have n<-xt to ask with which ner%ous svsteni a-e the.se glands most intimately connected .' You know- what the answer to tl 'scpiestion is. Theovarie.s receive no nerves but from the sympathetic, and the t-stes, as we showed above, m-eive nerves from the cerdno-spinal system only because they are expo.sed a. id require to be en low.'d with sensibility for tlieir protection. But if .sympathetic nerxes l)e the connecting link between the organ whose coiulitioJi excites the emotion and the nerve centre in which that emotion arises, that ner\ous centre must be the .sympathetic ganglia. Hunger and tliitvt are probably true emotional states, anl the arguments which follow would apply to them as well hs to other emotiotial states having i'oi- their basis certain conditions of the stomadi, but a.s they are not hy anv means univers,iJly hioked ui^n as emotions I shall pa.«s over them ami proceed to di.scus.s those al terations in the moral nature ^hich are .lue to fullness and erni.tine.sii of the stomach.

The heart receives a very large supply of sympathetic nerves, and .ts diseases as tatty degenemtion of its substance, and calcareous degenemtiou ot its arteries, are accompanied by very great depression of si.irits and often by Hgonies ot terror. The common forms of so-called heart disease, that is, impei"^ fections of the car.hac valves, and contractions of the cardiac orilices, are not. in the sense in which I am now speaking, disease at all ; for there is in these cases no tissue change, there is simply a change in mechanical conditions. The hver IS moderately well supplied with sympathetic nerves and there is a moder- ate amount ot disturbance of the moral natui-e in disease of its tissue as in can- cer, and in impairment of its functions as in congestion ; but as disejise of the liver, either structural or functional, seldom or never occurs without either struc- tural or functional disease of the stomach accompanying it, it is difficult to es- timate the amount of the disturbance of the emotions «iused by the hepatic con- ditions themselves. Emotional conditions excited by disea,ses of the kidneys are undoubtedly due in great part to the destructive changes going on in these or- gans, but they are also to a certain extent due to the uremic iK)isoning which necessarily accompanies them, aiul so tlie effect of the blood change and that of tlie organic change mask one another. But the case most clearly in favor of my argument is beyond question Adison's disease of the supni-renal glands lou Icnow that the number and size of sympathetic .. es sent to these small bodies IS extniordinarily great. You also know that they receive no cerebro- spinal nerves at all. Any of you who have seen aises of this disease or wlio have paid atteiition to the literature of the subject, are equally aware of the ex- tmordmary effect pmluced by disease of these }>odies iqion the monil nature l^ng iHjfore the ))a,tient is obliged by the extent of his illness to abandon hi.s usual occupations he is greatly troubled with listlessness, languor and low spir- its ; as tJie disease advances these symi)toms increiwe and attacks of terror and ••xtreme low sjiirits are common. Now to return to our old argument^the mor- bid action is m the supni-renal gland, the nerves which convey the impressions Nvhich excite emotional disturbance are necessarily here sympathetic nerves-- I he nerve centre m which the enu)tional disturbance takes place is therefore the sympathetic gfrngha-therefore the sympathetic ganglia are tiie nervous centre of emotional states. (■2) We ought next to consider the excitation of emotion by thoughts from aRS()ciation formed in the past of the species, or of the in.lividuai, but this su .;e;t IS so large and in a condeu.sed form would bo so little satisfactory that I fiav(; reluctantly conclmhid to omit it altogether. (3) The third and hwt cla.ss oi emotional excitants which we are to con- sider IS sense imi)ression8 acting uimn the moral nature without the intervention ot tli,.u,'lit. l.ie proper consideration of this part of the subject would alone occupy .«evenil Mich essays as I have time to reiul. 1 shah merely glance hastily atone instance of the class m.mtioned, namely: The excitation of cm.tions by sounds.

BUCKE ON THE SYMPATHETIC. l)ouglis the fmotionitl nature is movocl irrospectively of anv ideas tliat may be exciteil ; so at the bedside of a sick child its moans and cries of pain affect us quite out of proportion to and iiTesjxictive of the value our mind may set u\Kn\ them, for even if we know the chikl is not dangerously ill, nor » iHering very much, still we cannot pt-event, as is said in common language, its cries going t<i our heart, — and they do goto the heart, or at least to the centre of tlie enrojional nature, direct. So a ciy of pain or distress heard sudilenh' awakens a coiresponding emotion in the hearer before any thought Is aroused. T 1 ; pen of these two classes of soun 1 are, on the one hand sicken lai:- guage, and on the other hand music. Tiie formfu* we know appc^als directly to the intellect and does or does not arouse . emotion, according as the thought awakened is or is not associated with an emotional state. The latter, we also know, api)eals directly to the emotions and on'y awakens thought secondai-ily if it doi^s so at ail. Now does that class of sounds which appt^als directly to tin- moral n-iture possess any quality which the other class does not jwssess whiclt ■■vould make us think that it rathei' than the latter acts u^wn the sympatlietic '. ft has one such quality, namely: rythm. AH music is rythmic, and all lan- guage which appeals directly to the feelings, that is to say all poetry, is also lythmic. Now rythm is one of the leading qualities of the functions of the great s\ m[)athetic. All motions governed by it are rvthnn'c, the heait's motion, and the motions of the intestinal canal, the contractioTis of the uterus in ial)or. I myself have no doubt that tlio duration of pregnaTicy, the determining cause of which has pnzz'ed the world so much, as well as the periodic recuri-ence of ovulation are lx)th due to the same cause, namely; the rythm, or perioilicitv of function of the ^reat sympauhetic system. Doubtless the chief advantage of rogular'ty o^ time in taking meals is due to the fact that the gastric and salivarv glands and other o'-gans concerned mi digestion, being governed by the synip; ■ thetic, theii- functions are l)est performed rythmically. (.'omparing the twentv- four hours to a bar of music the three nu'als and sleep ai'e foiu- notes which niakr up the bar and they require to be struck in ti-ue time and with the same inten- sity day by day to keep Lhe music of ihe system true. (B; The oidy thing that remains for me to do to complete this very shoi't and impel feet sketch of a most important and much neglected subject, is to consider briefly the expression of the emotions to see if we can determine from Nvhich nej'vous syst'^m these phenomena proceed. As we cannot pretend to dis- cuss the whole of this branch of the inquiiy I shall limit the few remarks I have to make to the expression of (l).)oy, (2) grief, (S) hate, (•!•) fear, (o) and to the expression of, or rather the effect of, long continued excessive passion of any kind. (1) If joy is at all marked in degree it alters the heart's action — if excessivi' and sudden it arrests it nunnentarily, if more moderate in degree it makes it move freqi'ent and sironfier ; excessive joy causes palloi- for a short time and tlien'slight flushing, moderate joy heightens the complexion. If joy is at all extreme i^ excites Ipchrymation in persons of mobile nervous organization. Sudden and great joy destroys the apjtetite, apjtarently by checking the saliv- ary and gastric secretion '^ — moderate joy stinndates the appetite doubtless by exciting lhe secretions w'.dch assist in digest ijn. Now all the above are dis- turbances of functions which aie controlled by the sympathetic — but we know tliat joy a'so gives rise to movements of various kiiuis, for instance, laughter, chipping of the hands, stamping of the feet. The i)eculiarity of these )uove- niputs is that they are all rythmical and we know what a tendency there is foi' the fvuiciions of ^he sym))atbetic to be ]>ei'forauHl rythmically. Now I tlo not mean to ar^vie that it is the great synqtathetic which excites the nuiscles to ac- tion in t^ie production of tlies" movements, but what I wouM sugge.st for your consideration is that the great ._ mpathetic being the I'cvi-vous system primarily excited it excites the cerebrospinal system by nutans of its elaborate connection \ R.

' ;^- bi jiight about through tiie sympathetic. (3) Hate or rage if intense is nii^rked by jviUor and partial arrest oi tlic heart's action ; if moderate l)y tlushing ; if considerable but still not intens<' tin; ilushiug is extreme, the face becomes purple, the v(>ins of the neok find forelica I .swell. Monkeys as well as men are said to reddfu with jmssion. Some aii- tJiors say tJie pupils always eontrtict in j-jige, and this we can easily underst^ind for if the innscidar coat of tl e arteries is relaxed as it is shown to be by theili.-.- tention ot the ve.ssels, then the radiating Hbi-fs of the iris whicli are also sup ])lied by the .sympathetic, would l»e e(piaily in a sen i-paralyzcd state,and the. cii- cular tiiires which are supplied l»y the tliird nerve would have h-ss than usual to antagoaize their ordinary tonicity and the pupil would contract. In <>reai rage there is often trembling ; this ]»hen((menon J. shall considci- further nudci- the head <}f fear. The above mentioned are the primary signs of rag*; and tln-v jire all brought about through the symj)athetic. Other signs of ra'^c assiiarliii':. setting the teeth, clenching the tists. etc., are manifestly secondaiv ; thcs ."siili from intention iu our.selves or our ancestors of doing soniethiu" in conseoiiencc of rage and are not tlie direct effect of tlie i)assion itself. (4) The disturbanccis of function whith accompany fc;ir are fre<|nejit and feeble action of the heart, pallor, dilitation of tlu- pu|)ils. (1 wish von particn- iarly t-j remark that wiiereas in rage there is Ilushiug of the tkctiamlcontmctiou of the pupils, as I have shown aliove. in feaj- there is jiailor of tlie face and dili- tation of the pupils- -the nuLseular coats of the arteries iiud the nidiating hbres of the iris both being supi)liefl l)y the sympathetic, and Ixith being .stimulHted to contract under the intlueuce of terror, and lioth being ivlaxed in rage.) Jn feai- there is also suppression of the .salivary and gastric secitaions— extreme drvness of the month, and alisolut** abeyance of the apjKtite there is fieipiently increase, sometimes very marked of the urinary and intestinal secivtions. 'JVendiliug is one of the most charact(M'istic signs of fear. This is a movement of tlu.' volun tary nuiscles, but it is not a volinit^ry movement, the will having no control whatever over it. Trembling occurs in other emotional conditions besides fear, as in joy and ra ,.• — the shaking of ague though not associated with any ono- tional state is, 1 have no doubt, closely connected with emotional trenilding. No author with whose works I am acipiainted gives any exphmation of this l)henomenon. Were I to attempt one myself it would be that trembling is the peculiar movement of the voluntary muscular tissue when thrown into action not by its own proj)er nervous system, the cerebi-o-spinal, but by tlie sympathet- ic ; aufl I world argue that this was the correct view of the case— lirst, liecaus'' it is certain that trembling occurs when the sympiithetie is highly excited ; sec- ondly, l)ecause the cerelao-.spinal system cannot as far as we know cause such a movement, and cannot control it when caused ; and thu-dly, because of its pecu- liar rythmical character which allies it to other movements originatiri"- in the sympathetic, if I had time, which 1 have not at present, f could snpjiort these a,rguments by showing, I think conclusively, that ague, of which a iKH-nliar trendiling is one of the most |»roJui.ient symptoms, is certainly a functional (lis order of the great sympathetic ; and it is upon this fact that its peculi.ar p(>ri(,Mli city df>pends. With regard to the sweating ot gi-eat fear I have nt) ex|tlanatiou to otter, I will simply I'emai'k that when by division of sympat]ieti(; trunks .i part of the surface of vhe body is deprived of its e(aineeta)n withthe sympa- tlietic centres that pari of the surface is batheti in sweat.
