1225	''Is it right,''he seemed to ask,''to call this agency which I have discovered electricity at all?
1225	''That wo n''t do,''he said, with good- humoured impatience;''who was his predecessor?''
1225	And here the question may arise in some minds, What is the use of it all?
1225	But how is the health?
1225	But so long as we are unable to reply to the question,''What is an electric current?''
1225	Do these words shadow forth anything like the reality?
1225	Dr. Franklin says to such,"What is the use of an infant?"

1225	He found that, though the current passed through water, it did not pass through ice:--why not, since they are one and the same substance?
1225	If so, why should both cease when the wire ceases to move?
1225	Is then the act of decomposition essential to the act of conduction in these bodies?
1225	Is then the magnetic field really viscous, and if so, what substance exists in it and the wire to produce the viscosity?
1225	Is this effect an attraction and a repulsion at a distance?
1225	Is this new force a true repulsion, or is it merely a differential attraction?
1225	Might not the apparent repulsion of diamagnetic bodies be really due to the greater attraction of the medium by which they are surrounded?
1225	Still, if needed, an answer of another kind might be given to the question''What is its use?''
1225	What do we know, he asks, of the atom apart from its force?
1225	What has been the practical use of the labours of Faraday?
1225	What must be the consequence?
1225	What thought remains on which to hang the imagination of an a independent of the acknowledged forces?''
1225	What was the reason of this failure?
1225	Why, he asks, should decomposition thus take place?--what force is it that wrenches the locked constituents of these compounds asunder?

47396	Are you doubtful even whilst you publish?
47396	Atoms, or centres of force?
47396	But if the heat produced during life, and necessary to life, is not life after all, why should electricity itself be life?

47396	Lord Clarendon asked him:"You think it is now knocking at the door, and there is a prospect of the door being opened?"
47396	The gas company, I presume, came to an end; but what of the volatile liquid?
47396	Where was the tree rooted that bore such beautiful blossoms?
47396	Yet how can we properly speak of this sacred relationship, especially as the mourning widow is still amongst us?
47396	[ 27] But what was the use of this little spark between the shaken wires?
47396	and if so, what can be their smallest dimension?"
14986	(?)
14986	), which, acting at a distance and not by the intermediate particles, has, like the force of gravity, no relation to them?
14986	); for how, otherwise, could the results formerly described occur?

14986	16 Selenium(?)
14986	Does not the middle part of the wire, therefore, act here as an insulating medium, though it be of metal?
14986	Gold(?)
14986	May not this be an effect identical with the attractions of similar currents?
14986	The question then arises, what is this limiting condition which separates, as it were, conduction and insulation from each other?
14986	What, then, follows as a necessary consequence of the whole experiment?
14986	Will the relation of C and B to A be unaltered, notwithstanding the difference of the dielectrics interposed between them?
14986	_ Mercury_, periodide of, an exception to the law of conduction?
14986	account for the transverse effects of electrical currents?
14986	and is not the spark through the air an indication of the tension( simultaneous with_ induction_) of the electricity in the ends of this single wire?
14986	whether the intensity at which the current ceased to act would be the same for all bodies?
42245	What, I repeat, can you expect unphilosophical minds to make of so astonishing an affair as this? 42245 Among the thousands of_ tours de force_ and of dexterity accomplished by lightning, which should we take and which leave? 42245 And of that strange imprint of the cross? 42245 Are they to be attributed to the shock, to a general upheaval which brings back the circulation to its normal course? 42245 As the cabin stands under the shade of a pine tree, one is disposed to ask whether the lightning did not strike this pine? 42245 But could anything be more dreadful than the fate of certain ships that have been struck by lightning? 42245 But that does not prove conclusively that the lightning struck upwards from the ground; it may have rebounded(?) 42245 But what is the ordinary lot of these last when science spares them? 42245 Can it be that man''s thunder can repulse that of Jupiter? 42245 Can we attribute it to physical predisposition? 42245 Can we eat with impunity the flesh of animals which have been struck? 42245 Can we, then, marvel much that lightning should rival our feeble electric resources? 42245 Did I not say just now that lightning has sometimes-- though very rarely-- exercised a beneficial influence on sick people it strikes? 42245 Does it not seem as if the lightning plays with the lives of the trees as with man? 42245 Has it not been asserted that lightning may exert a benign influence on vegetation? 42245 How are storm- clouds to be detected? 42245 How are these things to be explained? 42245 How are we to explain the following facts of nature? 42245 How often one has remarked great tree trunks in the forests, decayed and desolate, standing sadly, like poor headless bodies? 42245 How resist all the thousand delusions and uncertainties and fears the entire thing calls forth? 42245 How was the lightning able to plant in the earth, with such inconceivable rapidity, the top of the tree where the roots had been? 42245 Is not the following phenomenon enough to make lightning more mysterious in its fantastic and varied mode of action? 42245 It is to be noted that the meteor did not follow the conductor; but, after all, is not the whole tower itself the most powerful conductor imaginable? 42245 May it not have been a tattoo- mark in spite of what his companions declared? 42245 Might they not be produced by this discharge upon the surface of the body-- or by the emission of electricity from the body struck? 42245 Moreover, why are we recommended always to put the conductor into a well, damp earth, or even into a small pond? 42245 Mysterious, is it not? 42245 Photography, the photo- electric pictures produced in the laboratories of physicists, Moses''s_ figures_(? 42245 To what cause can the invulnerability of the explosive matter be due? 42245 To- day, is it not regarded by astronomers as one of the most important forces of nature? 42245 Was it not the auxiliary of the gods in the dark ages? 42245 Was not it a veritable farce? 42245 Was there in these pictures nothing but ecchymoses-- infiltrations of the blood into the cellular tissue? 42245 What are the causes of this difference? 42245 What demon guided the lightning in these scenes of pillage? 42245 What is one to think of the extraordinary way in which the figure of the Saviour was left hanging? 42245 What is this resinous matter? 42245 What shall we say now of the photographing of a landscape on the inside of the skin of sheep which had been struck by lightning? 42245 Which shall we consider the privileged words-- those taken or those left? 42245 Who can explain why it sometimes glides into a stable full of cows without injuring one? 42245 Who is to explain these anomalies? 42245 Who knows whether, later on, when phonography is brought to perfection, it will not also register the noisy accompaniment to the electric flash? 42245 Why are certain organic or non- organic bodies visited repeatedly by lightning? 42245 Why does it not invariably kill those it strikes? 42245 Why not? 42245 Why should it not be the collaborator of man''s intelligence to- morrow? 42245 Why this preference? 42245 Would it act the same with atmospheric electricity as with that in our laboratories? 42245 Would the influence of the electric matter be more dangerous in the extremities than in the middle? 42245 and why does it sometimes not even wound them? 46763 Have you found your life distasteful?
46763	How long will it take?
46763	Inertia is an essential property of matter; is it a never- failing attendant on the mind? 46763 Then why do you come to waste my time about well- known facts that were published forty years ago?"
46763	''That wo n''t do,''he said, with good- humoured impatience;''who was his predecessor?''
46763	Again, to the same friend, he writes:"What?

46763	Do your joys with age diminish?
46763	Extreme severity''tis right to shun, For who could stand were justice only done?
46763	For when we met with it a second time he asked,''What is the name of that flower?''
46763	He instantly said,"What do you mean by abstracting?
46763	I long to be in and among them all; and where can I expect to be more happy, or better off in anything?
46763	If the surface of the earth gave our amateur traveller cause for wonder, what must have been his feelings when he first went down to the sea- shore?
46763	Is there nothing in the human mind which seems analogous to this power?...
46763	Must in death your daylight finish?
46763	Now, is this the case with mental inertia?"
46763	O grave, where is thy victory?''
46763	Or are they not always found contented to remain as if they were satisfied with their situation?
46763	Query by Abbott:''Then pray, Mike, why have you not answered my last before now since subjects are so plentiful?''
46763	The notes are brief-- but yet how much is there not expressed in them?
46763	Was the dolt ever willing to resign inanity for perception?
46763	Was the idle mind ever yet pleased to be placed in activity?
46763	Was your youth of pleasure wasteful?
46763	Who were his parents?
46763	Who would be content to forego the pleasures hourly crowding upon him?
46763	Words are given to him,''O death, where is thy sting?
46763	Writing nearly a quarter of a century ago Professor Tyndall answers this question as to"What is the use of it all?"

33810	And if it be an effusion does it seize upon the air whose motion the bodies follow, or upon the bodies themselves?
33810	And would there then be a diurnal motion of that_ Primum Mobile_ which is so great and beyond them all immense and profound?

33810	But what has attraction to do with stupefaction, or stupor with a Philosopher''s intellect, when he is discoursing about attraction?
33810	But what is that effluvium from crystal, glass, and diamond, since these are bodies of considerable hardness and firmly concreted?

33810	Is any such magnetical effluvium given off, whether corporeal or incorporeal?
33810	Is it the body itself, inclosed within its own circumference?

58404	But some may ask,_ Whether the whole Mind of one Creature, as the whole Mind of one Man, may not perceive the whole Mind of another Man_?
58404	But the question is, Whether the Sensitive Parts of a Human Society, do, at any time, Contemplate?
58404	But, my Thoughts are, at this present, in some dispute; as, Whether the Earth is a Part of the Production of Vegetables, as being the Breeder?

14000	All the waves of the spectrum, from the extreme red to the extreme violet, are thus acted upon; but in what proportions will they be scattered?
14000	And the question proposed is, What is the nature of that colour?
14000	And yet, when analyzed, what are industrial America and industrial England?
14000	Are the chemical rays, then, the same in the copper and the green beech?
14000	Are they always so?
14000	Are they then alike?
14000	Are we to ignore all this?
14000	But I would appeal confidently to this assembly whether such things exhaust the demands of human nature?
14000	But can small particles be really proved to act in the manner indicated?
14000	But what, in this case, could be the material forming the waves?
14000	But why have we to''wait a little''before we see this effect?
14000	Can we have the one without the other?
14000	Could we have seen these men at work, without any knowledge of the consequences of their work, what should we have thought of them?
14000	Did this mean that the light was altogether annihilated?
14000	Does she continue by the play of the same forces to form the vegetable, and afterwards the animal?
14000	He can not consider, much less answer, the question,''What is light?''
14000	How, then, did it fare with the Emission Theory when the deductions from it were brought face to face with natural phenomena?
14000	In what way different?
14000	Is it that there are two kinds of particles, the one specially fitted for transmission and the other for reflection?
14000	Is this exhibition of energy the work of the muscle alone?
14000	Let us begin our experimental inquiries here by asking, What is the meaning of blackness?
14000	Or shall we say it was authority merely?
14000	Shall we obtain two magnets, each with a single pole?
14000	Strange, is it not, that the beam should possess such heating power after having passed through so cold a substance?
14000	Surely there must be some hidden meaning in this little distance,_ d_, which turns up so constantly?
14000	The question now arises, what will occur supposing the ray from the water to follow the course_ n_''''''E, which lies beyond_ n_''''E?
14000	We may ask, in passing, what, without the faculty which formed the''image,''would Bradley''s wind and vane have been to him?

14000	Why?
14000	Will the amount of heat generated in the battery be the same as before?
14000	Would it not seem that Nature harboured the intention of educating us for other enjoyments than those derivable from meat and drink?
14000	Would you show him the necessary patience, or grant him the necessary support?
14000	is it simply a pure colour of the spectrum, or is it a compound, and if so, what are its component parts?
63372	AND WHAT IS IT ALL ABOUT?
63372	And to what extent shall we be able to reconcile the results of one observer using one reference frame, and a second observer using a different one?
63372	And what, now, can be deduced from these very simple looking equations?
63372	But did you ever observe anything suggesting the presence of time in the absence of space, or vice versa?
63372	But is its result in agreement with actual experience?
63372	But is this not a relic of animism?
63372	But once more the question arises: What could be done by an optical experiment?
63372	But what about these axioms themselves?
63372	But which particular material reference- frame shall we use?
63372	But who shall define point in terms of something simpler and something which precedes point in the formulation of geometry?
63372	By its fruits the ether hypothesis justified itself; but does the ether exist?
63372	Can we tell whether we are moving through this ether, even though all parts of our apparatus move together, and at the same rate?
63372	Do objects on the earth, on this account, look larger to a moon observer than they do to us?
63372	Does it take longer to swim to a point 1 mile up a stream and back or to a point 1 mile across stream and back?
63372	How do we judge about it?
63372	How shall we determine whether this body is at rest, or whether it is moving at high or low velocity through space?
63372	How shall we finally determine this?
63372	How shall we prove it?
63372	How then can we talk about the relative duration of these intervals?
63372	If a train is 1,000 feet long at rest, how long will it be when running a mile a minute?
63372	If it does not, are we justified in still calling it a law of nature?
63372	If it passes a second observer at 60 miles per hour, what is its length as observed by him?
63372	If the laws begin to become, intricate, why not reshape, somewhat, the fundamental concepts, in order to simplify the scientific laws?
63372	Is it really impossible to distinguish between rest and motion of a body if we do not take into consideration its relations to other objects?
63372	Is the expression of natural law independent of or dependent upon the choice of a system of coordinates?
63372	Is there then in the chaos of observational disagreements anything which is independent of all observers?
63372	Is this geometry ever realized?
63372	Is this the only possible explanation?
63372	Is time eternal or finite?
63372	It is not an event about which the headline writers are likely to get greatly excited; but what of that?
63372	It is then in order to investigate the converse: if the lines are parallel to begin with, are the angles equal?
63372	May not our belief in the uniformity of time be due to the uniformity of the motion of all observers on the earth?
63372	Maybe the representation will be a distorted one, but who is to say which is the absolutely undistorted representation?
63372	Perhaps the curvature was introduced by some peculiarity of our reference framework?
63372	SUCCESSIVE STEPS TOWARD GENERALITY Is then our laboriously acquired geometry of points in a three- dimensional space to go into the discard?
63372	Shall we carry over our idea( b) to answer the next question:"To which material body shall we attach our framework?"
63372	So it is altogether sensible for us to ask:"Is the universe of space about us really Euclidean in whatever of realized geometry it presents to us?
63372	The natural question here, of course, is"Well, where are their time axes?"
63372	This is all very fine; but how does the geometer know what postulates to lay down?
63372	Time can no longer be regarded as something independent of position and motion, and the question is what is the reality?
63372	WHAT MAY WE TAKE FOR GRANTED?
63372	WHO IS MOVING?
63372	WHO IS RIGHT?
63372	We believe there are sound waves produced, and all that; but what of it?
63372	We think we understand this, but our understanding consists merely of the unspoken query,"Why, of course; what is there to prevent?"
63372	Well, how would we prove it if he told us that our space axes did not run in precisely the same direction?
63372	What do we mean when we say that a plane is two- dimensional?
63372	What is the essential peculiarity of an absolute frame?
63372	What may we conclude from this coincidence?
63372	What tells us that the second just elapsed is equal to the one following?
63372	Where shall we look for such a preferred coordinate system?
63372	Why should there be this limitation of the time- factor?
63372	Why, then, should that introduced by relative motion puzzle us?
63372	Why?

22472	So how can you prove that something is not something else, when neither is something else some other thing?

22472	The other instances seem to me to be typical of-- something like migration?
22472	The question: Was it a thing or the shadow of a thing?
22472	The shapes were of great diversity-- or different aspects of similar shapes?
22472	Then Mr. Proctor wrote disagreeable letters, himself, about other persons-- what else would you expect in a quasi- existence?

22472	Will you look over your records and tell me where your engine was at about ten minutes past four, July fifth?"
22472	Would it be wise to establish diplomatic relation with the hen that now functions, satisfied with mere sense of achievement by way of compensation?
22472	You''d think that such a question as that would make trouble?

60271	And if not, why not assume that all lines drawn through a point outside a given line will eventually intersect it?
60271	Are there no outstanding difficulties?
60271	Are we to attribute the displacement to the gravitational field and not to the refracting matter around the sun?
60271	But are there such lines?
60271	But how do we know that the sun itself does not move with reference to some other body?
60271	But how much would the path of the projectile be bent?
60271	But if all things pointing in a certain direction are shortened to an equal extent, how are you going to notice it?
60271	But is there no relationship existing between the space and time of one body in the universe as compared to the space and time of another?
60271	But now if matter and light have the same origin, and matter is subject to gravitation, why not light also?
60271	But perhaps the moon itself has attractive power?
60271	But suppose I add that it is situated at Broadway and 117th Street, south- east?
60271	But then if the earth attracts the moon, why does not the moon fall to the earth?
60271	But what is beyond?
60271	But what is this ether?
60271	But what is this ether?
60271	But why should you?
60271	Can we not find something which holds good for all bodies in the universe?
60271	Did not Aristotle say that earth, air, fire and water constituted the four elements?
60271	Did not Ptolemy say that the earth was the center around which the sun revolved?
60271	Does the earth exert any gravitational pull on the moon?
60271	How do we know that our planetary system, and the stars, and the cosmos as a whole is not in motion?
60271	How does it appear?
60271	How will the time taken for light to travel in these two directions compare?
60271	If matter and light have the same origin, and if matter is subject to gravitation, why not light also?
60271	If one, two and three dimensions, why not four-- and five and six, for that matter?
60271	If water is the medium for the waves of the sea, what is the medium for the waves of light?
60271	If, however, there is no ether, or if we are to ignore it, how are we to get the velocity of bodies in space?
60271	In particular what can be done with respect to gravitational phenomena?
60271	Is it not, then, possible to regard the system of coordinates as at rest, and the centrifugal forces as gravitational?
60271	Is there no possibility of error?
60271	It may be asked, why does not a bullet continue moving indefinitely once it has left the barrel of the gun?
60271	It may well be asked, what bearing have these laws of Newton on the question of time and space?
60271	Must we then revise our ideas of an ether?
60271	Perhaps you think the attraction due to the air in between the magnet and iron?
60271	Probably the further up you go the less does the earth attract the apple, but at what distance does this attraction stop entirely?
60271	Still Another Victory?
60271	Suppose I say to you that the chemical laboratory of Columbia University faces Broadway; would that locate the laboratory?
60271	Suppose these two- dimensional beings were living on the surface of the earth; what could they see?
60271	Suppose we ignore the ether altogether, what then?
60271	To begin with, why should Einstein suppose that the path of a ray of light would be affected by the son?
60271	We say that it takes a"long time"to get from New York to Albany; long as compared to what?
60271	What Is This"Ether"?
60271	What charges give rise to light waves?
60271	What has nature to do with the coordinate systems that we propose and with their motions?
60271	What has this Albert Einstein done to merit such extraordinary praise?
60271	What is the explanation?
60271	What is this"something else"?
60271	What of the remaining 42 seconds?
60271	What was it?
60271	What would be the shape of its parabola?
60271	Where is the fundamental set of axes?
60271	Where is the rope that pulls the iron towards the magnet?
60271	Why did the planets move in just this way?
60271	Why is not the velocity of the planets reduced in time, just as the velocity of a rifle bullet decreases owing to the resistance of the air?
60271	Why not consider them both as brought into our equations by the agency of mathematical transformations?
60271	Why not?
60271	Why should there be to any other so- called"force,"which like centrifugal force, is independent of the nature of the matter?
60271	Why then is there any difference in the essence of the two?
60271	Why, then, question further?
60271	Will you apply the yard stick?
60271	Will you pass judgment with the help of your eyes?
60271	Would Einstein''s figures be confirmed?
60271	Would an apple reach the earth if thrown from the moon?
60271	Yet how can we conceive of the iron being drawn to the magnet unless there is some go- between?
60271	You may say, why not take our standard of time as the standard, and measure everything by it?
60271	[ 1] But what is this light?
60271	[ 5] Where Did Einstein Get His Idea of Gravitation?
60271	some medium not readily perceptible to the senses perhaps, and therefore not strictly a form of matter?
60271	that, in fact, not only the earth''s motion, but the motion of all the planets is regulated by the same means?

33504	And after what manner are they inflected to make those Fringes?
33504	And among such various and strange Transmutations, why may not Nature change Bodies into Light, and Light into Bodies?
33504	And considering the lastingness of the Motions excited in the bottom of the Eye by Light, are they not of a vibrating nature?
33504	And do not hot Bodies communicate their Heat to contiguous cold ones, by the Vibrations of this Medium propagated from them into the cold ones?
33504	And do not the Motions once excited continue about a Second of Time before they cease?
33504	And do not the Vibrations of this Medium in hot Bodies contribute to the intenseness and duration of their Heat?
33504	And do not the three Fringes of colour''d Light above- mention''d arise from three such bendings?
33504	And doth it not readily pervade all Bodies?
33504	And in general, is it not from the same Principle that Heat congregates homogeneal Bodies, and separates heterogeneal ones?
33504	And is it not( by its elastick force) expanded through all the Heavens?
33504	And is not this Medium exceedingly more rare and subtile than the Air, and exceedingly more elastick and active?
33504	And may not its resistance be so small, as to be inconsiderable?
33504	And what else is a burning Coal than red hot Wood?
33504	And when a Man by a stroke upon his Eye sees a flash of Light, are not the like Motions excited in the_ Retina_ by the stroke?
33504	And why does not common Salt, or Salt- petre, or Vitriol, run_ per Deliquium_, but for want of such an Attraction?
33504	Are not all Hypotheses erroneous which have hitherto been invented for explaining the Phænomena of Light, by new Modifications of the Rays?
33504	Are not all Hypotheses erroneous, in which Light is supposed to consist in Pression or Motion, propagated through a fluid Medium?
33504	Are not the Rays of Light in passing by the edges and sides of Bodies, bent several times backwards and forwards, with a motion like that of an Eel?
33504	Are not the Rays of Light very small Bodies emitted from shining Substances?
33504	Are there not other original Properties of the Rays of Light, besides those already described?
33504	Do not the Rays of Light in falling upon the bottom of the Eye excite Vibrations in the_ Tunica Retina_?
33504	For what else is a red hot Iron than Fire?
33504	Have not the Rays of Light several sides, endued with several original Properties?
33504	How came the Bodies of Animals to be contrived with so much Art, and for what ends were their several Parts?
33504	How do the Motions of the Body follow from the Will, and whence is the Instinct in Animals?
33504	If it be asked, what then is their Cause?
33504	Is not Fire a Body heated so hot as to emit Light copiously?
33504	Is not Flame a Vapour, Fume or Exhalation heated red hot, that is, so hot as to shine?
33504	Is not this Medium much rarer within the dense Bodies of the Sun, Stars, Planets and Comets, than in the empty celestial Spaces between them?
33504	Was the Eye contrived without Skill in Opticks, and the Ear without Knowledge of Sounds?
33504	Whence is it that Nature doth nothing in vain; and whence arises all that Order and Beauty which we see in the World?
33504	and are not these Vibrations propagated from the point of Incidence to great distances?
33429	Has meteorology made such progress?
33429	Have not the''American Association for the Advancement of Science''arrived at some definite and sound conclusion upon the subject?
33429	How, then, did you acquire the information you seem to possess?
33429	I have,he says,"long held the proper inquiry to be,_ what are storms_?
33429	I must understand this,said he;"how is it?"
33429	Long cold snap,we exclaim;"how long will it last?"
33429	Now, what is that?
33429	Shall I have fair weather now till I get home?
33429	Again, where are the_ upper regions_, from which the lateral overflow takes place?
33429	And all this without any relation, whatever, to the contiguity of the oceans?
33429	And now, what is the explanation of all this?
33429	Are all these the result of simple evaporation, ascent to a colder region, condensation, and descent again?
33429	Are they in fact so drawn?
33429	But further still, what heating and ascending process is it that makes the variable winds north of the tropics?
33429	But of what kind?
33429	But what says Burnes respecting the winds of this part?
33429	But what_ power_ impels the winds, which thus meet at these points?
33429	But which is the stronger force?
33429	But why does he say this_ covers the storm_?
33429	Can any one believe they were successive rotary gales?
33429	Can he not arrange with a moderate lens, to move his engine with the rays of the summer sun?
33429	Can it be, you ask, that this driving wind is but an_ incident_ of the storm?
33429	Can the lateral tide, if there be one, affect the weather?
33429	Cumulus, broken stratus, patches of cirro- cumulus or cirro- stratus, or scud?
33429	Do the magnetic currents, passing upward with increased force, lift, elevate the atmosphere?
33429	Does any man believe that either current exists?
33429	Does it heat so fast as to_ keep up the ascensive force_ without intermission, at twenty- five, or twenty, or ten miles the hour?
33429	From whence, then, does it come?
33429	Gloomy from what?
33429	Has the earth any agency, and if so, what?
33429	Her interior deserts are extensive and intensely hot-- why are they rainless?
33429	How are they produced?
33429	How are they_ impelled_?
33429	How can a thaw come?
33429	How coming?
33429	If neither the ceiling nor floor of the chamber have any agency in producing it, what does?
33429	If so, how then can we explain the diurnal fall while magnetism is most active?
33429	If the latter, why a tendency to rotation from right to left?
33429	If the upper one, why is the interloper at the surface noted and quoted to prove what a storm is?
33429	In what manner does it act?
33429	Is it distinct from it, and if so, what is it doing there?
33429	Is it not then the agent?
33429	Is it then the attraction of magnetism which produces the barometric oscillations?
33429	Is not our air the same and our heat the same?
33429	Is that the ascensive force of air at 100 °?
33429	Is the true one always the upper one, and why?
33429	Is there such an agent?
33429	Is this vast suction found by the unlucky mariner who may be drawn within the vortex?
33429	Must it not be, at least, double that of the belt of calms, or the"great region of expansion,"as Professor Dove calls it?
33429	Nay, what shall be done with Professor Dove?
33429	Nay, would not gravity fill the second vacuum from_ above_, rather than from the south- west side?
33429	Now what occasioned this general depression of temperature, and local fall of snow?
33429	Or is it a mere mechanical effect of meeting,"coming into each other,"or"over- sliding?"
33429	Precisely so; but why carried away?
33429	She is not more timid than others; why does she invariably thus build?
33429	The belt of rains, formed by the currents of the two trades, threading their way through each other-- how are they produced?
33429	This brings us to the inquiry, how was it done?
33429	Upon_ what cause_ do these great central phenomena, so vast, so regular, so wonderful, depend?
33429	What do these gentlemen mean?
33429	What does Professor Dove mean by the term_ impulsion_, as applied to the winds?
33429	What is the ascensive power of an area of atmosphere of 100 °?
33429	What is the height of this expansion?
33429	What is the_ motive power_ of this connected atmospheric machinery, whose action and influence extend over the entire globe?
33429	What makes her"_ impulses_"differ from those of other birds, and always in the_ same manner_?
33429	What power placed it there, and for what purpose?
33429	What says Mr. Ericsson to this?
33429	What, then, is the ascension force of air at 100 °?
33429	Where is the great uprising suction during the prevalence of this extensive surface horizontal monsoon beneath it?
33429	Who dare belie The constant sun?"
33429	Who dare belie The constant sun?"
33429	Who shall we believe?
33429	Why do they not ascend?
33429	Why do they not have a_ vortex_, a_ monsoon_, or even a_ shower_?
33429	Why does it not ascend?
33429	Why draw only from under the central belt of rains?
33429	Why should the place where the currents thus pass through each other be a place of almost daily precipitation?
33429	Why should we be exempt?
33429	Why then is it rainless?
33429	Why?
33429	Would not such a fact be perfectly conclusive in any other science except theory- swathed meteorology?
33429	_ And the opposite is true every where upon the land._ How much hotter is the ocean and air under this supposed vortex?
33429	_ What, in short, is the power, and how is it exerted?_ To these questions, Mr. Redfield''s essays furnish no comprehensive answer.
33429	and not,_ how are storms produced_?
33429	and will not the air incline to rush in, to some or all these successive vacuums, from some other side than south- west?
33429	and, if so, why the preference of vacuums by the air, and_ when, where, and why_, should the_ successive vacuums stop_?
33429	fog, or stratus, or a stratum of scud, or what?
33429	not"How are storms produced?"
33429	or, have these deserts the power of selecting the quarter from which their vacuum shall be filled, and of delegating it to succeeding vacuums?
33429	or, that every one of them was not an interloping wind on which the true storm wind was superimposed?
33429	or, will it all voluntarily rush in, and leave a new complete vacuum?
33429	that brings in the warm air and fog of the Gulf Stream upon our_ snow- clad coast_, in mid- winter, to increase the January thaw?

39566	And can you, my young friends, be careless about your own salvation while Samuel is so anxious for you? 39566 And what is radiation?"
39566	And what, Mr. Hume, about the ice water?
39566	And, Mr. Wilton,asked Peter,"does not the Bible say that''God created all things for his own glory''?"
39566	Ansel, have you ever heard the''dew point''spoken of?
39566	Ansel, will you state the theories which have been held touching the nature of heat?
39566	Are you becoming discouraged and almost ready to give up all effort to follow Christ?
39566	Are you unwilling to come to him-- to trust him and submit to him?
39566	Are your thoughts and feelings and opinions about Christ and salvation the same as they were six weeks ago?
39566	But by what agency does man achieve the mastery of Nature? 39566 But can you wholly get rid of the conviction that the Bible is the word of God, written by holy men inspired by the Holy Spirit?"
39566	But how does this carry heat from the warmer region to the colder regions around?
39566	But how would it please you if my talk upon the ministry of pain should prove to be very much like a sermon?
39566	But were you not interested and pleased with the discourse? 39566 But what did you mean?
39566	But why do you say, of course? 39566 But would not all these natural agencies subserve essentially the same ends in the discipline of unfallen and sinless beings?
39566	But, Samuel, did you not pray for Mr. Hume also, and talk with him?
39566	But,said he,"does not the book of Nature-- your Bible, as you call it-- have something to say of God?
39566	Can you tell us, Ansel, whether the earth receives heat from the moon and stars?
39566	Can you tell us, Peter, why tubs of water set in a cellar should have this effect?
39566	Can you tell why a newspaper spread over a tomato vine keeps the frost from the vine?
39566	Did you ever think, Ansel, that you were very ambitious?
39566	Did you expect a month ago that at this time you would be feeling and acting as you now feel and act?
39566	Do not men heat and burn bricks, not to soften them, but to harden them?
39566	Do you believe that Christ is able to save you?
39566	Do you believe that he is willing to save you?
39566	Do you know what is meant by it?
39566	Do you look upon this irregular expansion and contraction of water,asked Mr. Hume,"as a real exception to the rule that heat expands bodies?"
39566	Do you wish now that you had fought it through, as you proposed, and kept all your feelings to yourself?
39566	Have not you, Mr. Hume, been treating Christ and the Holy Spirit as Samuel feared that you would treat him?
39566	Have you ever noticed whether cloudy nights or clear nights are the warmer?
39566	Have you no more enjoyment in reading the Scriptures and in your prayer in secret than you had a week ago?
39566	How could the dew fall upon the under side?
39566	How could we tell,asked Peter,"without knowing what kind of work the machine was designed to do?"
39566	How does the form of the earth operate to produce inequality of temperature?
39566	How is water formed from these two gases? 39566 How would such a plan please the other members of the class?"
39566	I am glad to hear that; but can you tell how they are different?
39566	I want to ask,said Peter,"how this internal heat came to exist, and how it is maintained?"
39566	If I understand you, then,he said,"you would like a course of lessons in the teachings of Nature?"
39566	In this bountiful supply of heat to warm the earth and serve human needs must we not see a kind design on the part of the Creator? 39566 Perhaps,"he continued,"you would prefer to study one of the historic books of the Old Testament?"
39566	Peter, what is the third method by which heat passes from place to place?
39566	Samuel, what is the cause of day and night?
39566	That is the old and common expression, but what is meant by latent heat?
39566	Upon what does the dew point depend?
39566	Was your answer correct, then?
39566	We use heat also in cooking our food,spoke up Peter:"is it not because heat destroys the cohesive attraction, and thus softens it?"
39566	What answer did you try to give him, Ansel?
39566	What are some of those means for transferring heat which seem to you to operate the same in the annual as in the daily changes of temperature?
39566	What book can you find which is true if the Bible is not true?
39566	What do you mean, Ansel?
39566	What do you think it is that hinders your coming into light and joy as others have done?
39566	What do you wish?
39566	What have you been reading, Ansel, that has put such thoughts into your mind?
39566	What have you tried to do for Christ?
39566	What is cohesive attraction?
39566	What is combustion?
39566	What is it, Ansel?
39566	What is meant by convection of heat?
39566	What is meant, Ansel, by the''conduction''of heat?
39566	What is that heat called, Ansel, which is absorbed by a body with no rise of temperature?
39566	What is that inequality of temperature which is produced by the shape of the earth?
39566	What is the cause of the sun''s heat?
39566	What is the evidence,asked Samuel,"that the dynamic theory of heat is true?"
39566	What is the third great natural source of heat? 39566 What leads you,"asked Mr. Wilton,"to present yourself to the church, asking for baptism?"
39566	What will you say, Peter?
39566	Why did you stand upon a rock?
39566	Will you correct your answer?
39566	Will you not tell us,said Samuel,"how these ocean currents are produced?
39566	Will you please explain this?
39566	Will you please tell us, Mr. Wilton, how this weakening of cohesive attraction is explained upon the dynamic theory of heat?
39566	Would it be wise and well to take no account of foreseen events? 39566 ''And who are these lads and young men for whom all this work and wisdom is expended?'' 39566 ''Can the Ethiopian change his skin or the leopard his spots? 39566 ''Pray, sir,''he says to the master,''what is this strange contradictory institution?'' 39566 ''What must I do to be saved?'' 39566 --_Youmans._What is the second method by which heat passes from place to place?"
39566	30:"Sirs, what must I do to be saved?"
39566	A hundred times a day the questions came, What if there be a God who holds me responsible?
39566	A self- righteous young man came to Jesus asking,''Good Master, what good thing shall I do that I may inherit everlasting life?''
39566	Ansel, have you studied geology?"
39566	Ansel, how shall we explain this?"
39566	Ansel, what part of the atmosphere is warmest?"
39566	Are there different conditions and different duties required of different men?
39566	Are they mixed together as oxygen and nitrogen are mingled in the air, or are they chemically united?"
39566	Are we to suppose that the column of heated air reaches to the top of the atmosphere?"
39566	Are you contented to live''having no hope and without God in the world''?
39566	Are you, Samuel, in your interest in studying Nature, forgetting Christ and the souls of men?"
39566	At length he thought,''Why should I not?
39566	But did God''s plan excuse his treason against his Lord?
39566	But does it seem reasonable that the world was designed merely as a place of punishment for men by reason of their wickedness?"
39566	But does not that condensation which forms the cloud- ring set free latent heat, and thus intensify the great heat of the equator?
39566	But here two questions arise: What is the glory of God?
39566	But how is the weight raised?
39566	But how shall we know the object for which God made and governs the world?"
39566	But if the casket be so worthy, what shall be said of the gem which is enshrined within?
39566	But what did you learn last Sunday?"
39566	But what is one iceberg to the thousands which drift yearly from the frigid zones toward the tropics?
39566	But what is the Gulf Stream, though it be fifty fold greater than all the rivers of the world, in comparison with the whole sum of the ocean streams?
39566	But what is the question which you wished to propose?"
39566	But what is the question?"
39566	But what is the setting for this gem?
39566	But what kind of evidence am I to look for?"
39566	But whence comes the force necessary to accomplish this?
39566	But whence comes the heat of combustion?
39566	But why do not the glowing rays of the sun raise the temperature at once to the highest possible point?
39566	But why do not the vegetables begin to freeze as soon as the water?"
39566	But why not endow living creatures with nerves of sensation which could experience pleasure, but could not feel pain?
39566	But why should not God embrace in his plan that great event, the fall of man, which he foresaw in the future?
39566	Can you blot out your past sins?
39566	Can you change that condemnation by your feeble, fickle resolutions to reform?
39566	Can you erase the record which stands written in the book of remembrance on high?
39566	Can you not now tell why water is incombustible?"
39566	Can you tell us, Ansel, how the temperature of the earth is affected by the atmosphere?"
39566	Can you tell us, Peter, at what season of year the earth is nearer the sun?"
39566	Could his late repentance call them back to life and hope?
39566	Did Mr. Hume say that what he calls''The book of Nature''contradicts the sacred Scriptures?"
39566	Did the Creator then''Bid his angels turn askance The poles of earth twice ten degrees and more From the sun''s axle''?
39566	Did this plan touching Christ make the apostasy of man a necessity?
39566	Did you ever see barefoot boys running in the cold dew stop and stand upon a stone or rock to get their feet warm?"
39566	Did you not carry the same idea of being chief into your plans and expectations for the future?
39566	Do all bodies conduct heat with equal rapidity?"
39566	Do clouds tend to produce inequalities of temperature?"
39566	Do n''t you remember how he used to laugh at the idea of being plunged in the river in honor of a dead man?
39566	Do not men produce by cultivation better fruits and vegetables than Nature ever grows when left to herself?"
39566	Do not the laws of Nature bring suffering to the good and the bad alike, and happiness also to all classes of men?
39566	Do not the works of Nature tell of the same God whose being and character were preached to us yesterday from the Holy Scriptures?"
39566	Do you know, Ansel, how to ascertain the dew point at any time?"
39566	Do you really and honestly wish to be saved from sin?
39566	Do you remember what was said about the production of cold by expansion and of heat by compression?"
39566	Do you think that my long trial of doubt and unrest and pain of heart can ever be blessed to my good?"
39566	Do you wish to study the evidences of the truth and inspiration of the Holy Scriptures?"
39566	Does Nature punish those whom you call the wicked?
39566	Does Nature reward the righteous?
39566	Does any one think of another cause of inequality of temperature?"
39566	Does it not mean that he made the world so good and perfect that all creatures ought to praise him on account of it?"
39566	Does it not speak of an infinitely wise and good Creator and Governor?
39566	Does that seem to you to be true, Samuel?"
39566	Does the temperature rise in any place?
39566	Does the world seem as if fitted up to be the dwelling- place of holy beings?"
39566	During the past few weeks you have heard others asking,''What shall we do to be saved?''
39566	Have you never heard of setting tubs of water in cellars to keep vegetables from freezing?"
39566	Have you succeeded in getting rid of your sins?
39566	He could only cry out in astonishment,''Father, why am I, thine obedient son, thus smitten?''
39566	How are we to combine these two sets of arrangements in our thinking?"
39566	How can God make his frown felt except by looking pain, so to speak, into the sinner''s conscience?
39566	How could it be otherwise?
39566	How is carbon brought into this state of suspense, waiting to dash upon oxygen and develop heat?
39566	How is this accomplished?
39566	How is this diurnal change of temperature alleviated?"
39566	How is this provision for suffering in man and in all sentient creatures consistent with the benevolence elsewhere shown?
39566	How much heat is given out in the freezing of water?"
39566	How shall their motions be explained?
39566	How shall we estimate the strength of this force?
39566	How were you interested in the sermon?"
39566	How would that affect the rate of radiation from the earth?"
39566	How would you apply this principle to the subject we are now considering?
39566	Hume?"
39566	Hume?"
39566	Hume?"
39566	Hume?"
39566	Hume?"
39566	Hume?"
39566	If Nature and Nature''s God have blessings in store for the willing and the obedient, why should not I know this and receive my share?"
39566	If a second example were made of a second ungodly city, would the expression of divine wrath be weakened?
39566	If, however, you want something else than the salvation which Jesus gives, what can you expect but perplexity, difficulty, darkness?
39566	Is it a new and original generation of heat, or is it merely a transfer?
39566	Is it because it evaporates before it reaches a sufficiently high temperature?"
39566	Is it not reasonable to believe that he designed it for their use?
39566	Is it wrong to wish for such an experience?"
39566	Is that so?"
39566	Is this plain to you, Ansel, and does it seem reasonable?"
39566	Is this possible?
39566	Is your happiness here and hereafter more important to Samuel than to yourselves?"
39566	Jesus has gone to prepare mansions for those who will, as he foresees, believe in him: why not make provision for foreseen evils also?
39566	Mr. Hume, can you suggest any method by which we can estimate the amount of heat which is carried north and south by the return trades?"
39566	Mr. Wilton proposed the question to the class:"What shall be our next course of lessons?
39566	Must he, then, after having caught a glimpse of life and joy, be cut off from hope and be driven from God for ever?
39566	No one else answered, and finally Mr. Hume said:"I suppose, of course, that you refer to the land and sea breezes?"
39566	On the other hand, when the sun sets and his heat is withdrawn, why does not the temperature fall suddenly to the lowest possible point?
39566	Ought we to believe that God planned the world for an object for which it never has been and never will be employed?
39566	Perhaps you will tell us what seems to you to be that object?
39566	Peter, have you ever seen a coal- pit?
39566	Plant a grain of corn in midwinter: why does it not germinate and grow?
39566	Samuel, what is a third cause of unequal temperature?"
39566	Samuel, will you name the second chief source of heat?"
39566	Shall we from the burden flee?
39566	Some even ventured to approach Mr. Hume himself with their raillery:"What do you think now of being dipped in the river in honor of a dead man?"
39566	The Creator foresaw the fall of man; is there no objection to the supposition that, knowing that man would sin, God made no provision for it?
39566	The young man answered,''All these have I kept from my youth up; what lack I yet?''
39566	Then Ansel spoke up:"Mr. Wilton, why can we not study something which we know to be true?"
39566	Was it merely an accident that the dove was fitted to become the emblem of purity and of the Holy Spirit?
39566	Was not this so?"
39566	What care could give him knowledge of the qualities of all natural substances, that he might avoid their dangerous properties?
39566	What carefulness could guard against the tornado on the land, or the hurricane and the cyclone upon the sea?
39566	What could his confession do for the young men already, perhaps, among the lost through his influence?
39566	What did he mean by that, Samuel?"
39566	What does man need besides scope and reward for exertion?
39566	What effect, Peter, has the unevenness of the earth''s surface upon temperature?"
39566	What if Christ be the Son of God?
39566	What if a third example be made of a third city?
39566	What if every wicked city is made an example?
39566	What if hydrogen were put in the place of nitrogen?
39566	What if some other equally active element were mingled with oxygen to form the atmosphere?
39566	What if there be a future life and a judgment day?
39566	What if, in place of nitrogen, vapor of sulphur were substituted?
39566	What is another cause of inequality of temperature?"
39566	What is meant by this?
39566	What is that?"
39566	What is the chief form of this which is used for the production of heat?
39566	What is the general principle touching the effect of heat upon bodies?"
39566	What is the meaning of this?
39566	What is understood, Ansel, by this term, specific heat?"
39566	What need is there of a creator?
39566	What power should save him from the bursting of the volcano and the jaws of the earthquake?
39566	What shall I render unto the Lord for all his benefits?
39566	What was a confession in comparison with the ruin he had caused?
39566	What will be the end of his groping in darkness?
39566	What would be the effect, Ansel, if the atmosphere were as warm, or warmer, at the top than at the surface of the earth?
39566	What, Mr. Hume, do you think the effect would be upon creatures such as we all know men to be?"
39566	When radiant heat falls upon a body, what becomes of it?"
39566	Which will encourage the larger manliness and nurture the higher culture and strength?
39566	Who can prove that the universe did not exist from eternity?
39566	Who should stand sentinel against the unseen poison borne upon the wings of the wind?
39566	Who will mention another method by which heat is economized?"
39566	Who will suggest it?"
39566	Who will tell us?"
39566	Why does not the dew-- for frost is nothing but dew frozen as it forms-- come upon the under side of the paper?"
39566	Why is this, Samuel?"
39566	Why not give up my own will?
39566	Why not pray that God''s will may be done?''
39566	Will some one explain this?"
39566	Will some one mention some of the general methods by which the waste of heat is prevented?"
39566	Will some one now state the manner in which the dynamic theory of heat explains this expansion?"
39566	Will some one suggest what this agency is?"
39566	Will you bolt the door?
39566	Will you not come to him?
39566	Will you not trust his promises and commit yourselves to his hands to be saved?
39566	Will you tell us, Peter, the first and chief of these effects?"
39566	Will you tell us, Samuel, how winds are caused?"
39566	Will you tell us, Samuel, the first adjustment or arrangement upon which the temperature of the earth depends?"
39566	Will you, Mr. Hume, suggest one of the general arrangements for the economical use of heat?"
39566	Wilt thou not bow their pride of heart and turn their wills and make their hearts tender, gentle, and believing?
39566	Wilt thou not draw them to thyself?
39566	Wilt thou not smite the rock, and cause the waters of penitent grief to flow?
39566	With these machines before you, could you tell me whether the inventor were a wise and skillful machinist?"
39566	Would God forgive and raise to heavenly heights a man who had dragged others down to hell?
39566	Would it be possible that Christ should fill his soul with blessedness while his victims were drinking the wine of the wrath of God?
39566	Would it have been wiser and better to leave out of account that most stupendous fact in the history of the human race?
39566	Would that seem to be a fitting employment for the sinless children of the all- loving Father?
39566	Would you be satisfied to have a commonplace experience, such as thousands of others have, which would attract no special notice?
39566	Would you like to study one of the Epistles-- the Epistle to the Romans or that to the Hebrews?"
39566	Yet, taken as a whole, can one doubt that variety of climate and change of temperature are of advantage to man?
39566	You cry out,''Men and brethren, what shall we do?''
39566	and Peter''s answer,"Lord, to whom shall we go?
39566	and the lion, of strength and regal state?
39566	and, What is it for God to glorify himself by his works of creation and government?
39566	he asked;"do you think Genesis less trustworthy than the Epistle of Paul?"
39566	the ant, to be the type of prudent industry?
39566	the horse, of spirit and daring?
39566	the lamb, to be the emblem of gentleness, of Christ the gentle Sufferer, and of his suffering people?
22156	A cyclone?
22156	About how high could we make this kite go, sir?
22156	Ah write it? 22156 Ai n''t I asking you to?"
22156	Ai n''t time, jest time, all over?
22156	All clouds are fogs, sir?
22156	All for our own?
22156	All those observations are sent to Washington, are n''t they, sir?
22156	An''the courts have a ruling that weather records is evidence?
22156	An''what''s a Kraker- something sunset?
22156	And I suppose you think I told you to?
22156	And around noon- time?
22156	And barometers like mine?
22156	And can you always tell what the weather is like, all over the country?
22156	And did n''t you?
22156	And even if the person you help is never going to be able to do you any good, why, that''s all the more reason for helping, is n''t it?
22156	And have they all got rain gauges like mine?
22156	And if the basket were sixty feet high, as high as a barn?
22156	And in the evening?
22156	And was that the way that you lads figured out that my fruit was likely to be frozen?
22156	And what is the present velocity?
22156	And where are the others?
22156	And where does the cold wave come in?
22156	And why does that crackle? 22156 And wind- measurers, like my anemometer?"
22156	And you say the shooting was before half- past eight?
22156	And you went on working?
22156	Any of you boys coming my way?
22156	Anything wrong?
22156	Are n''t they dandies?
22156	Are n''t you going to tell him about the frost?
22156	Are they all here?
22156	Are they the best kites for lifting, sir?
22156	Are you ready?
22156	At any special distance, sir?
22156	Bad weather coming, is n''t there, Anton?
22156	Because water is denser than air?
22156	Build two- thirds of the whole two thousand miles by some underwater system, constructing the wall under water? 22156 But do many people get killed with lightning?"
22156	But do n''t you think he can draw?
22156	But does n''t anybody know why it rains?
22156	But does n''t it cost an awful lot?
22156	But how did they find that out?
22156	But how is that going to show the time?
22156	But suppose a wind comes up and blows the heat away?
22156	But suppose we do n''t get it just right?
22156	But the sunset colors, sir?
22156	But what has that got to do with the army, sir?
22156	But what''s the cause of ball- lightning?
22156	But why are they always so regular?
22156	But why does thunder make a noise?
22156	But why in the world should a hail- stone be made like an onion?
22156	But why, sir?
22156	Ca n''t we do it by hand?
22156	Can we, sir?
22156	Could an aeroplane get up there?
22156	Could n''t I hold one of those small kites, sir?
22156	Could n''t we interest some one else to do them, just to help the thing along?
22156	Dan''l,said the younger boy, reprovingly,"why do n''t you use that thick head of yours a little?
22156	Dead?
22156	Did anny one ever show you annything about printin''?
22156	Did n''t you?
22156	Did that follow a volcanic eruption, sir?
22156	Did you ever notice that there''s a little crack between each rail? 22156 Did you?"
22156	Directly opposite to the storm?
22156	Do I? 22156 Do n''t I have to run with it?"
22156	Do n''t you think that I ought to try to find Father first?
22156	Do you happen to know, though, Bert, what makes the colors of sunset? 22156 Do you reckon five seconds to a mile between the lightning and the thunder?"
22156	Do you suppose I''d rob him of the fun of telling you? 22156 Do you suppose he''s got three?"
22156	Do you suppose it''ll ever dry up, Ross?
22156	Do you suppose the Weather Bureau in Washington would make them for us and let us have a few copies?
22156	Do you suppose, sir,asked Tom,"that it would be safe to send up the kite?
22156	Do you think we ought to get mixed up in a thing like this?
22156	Do you want to go along?
22156	Does it look so bad?
22156	Does that depend on the wind?
22156	Every day?
22156	Going to fly them tandem?
22156	Going up, sir?
22156	Goliath, the strong man, the Flying Squirrel Brothers, Androcles, the lion tamer, Princess Tiny and the rest?
22156	Got the cup?
22156	Hail is electric, too, is n''t it?
22156	Have any of you boys thought at all about what''s going to happen to Anton, when he grows up? 22156 Have n''t you some scheme?"
22156	Have sun- spots anything to do with the weather, sir?
22156	Have you a long straight board?
22156	Have you seen a copy of our paper?
22156	Have you?
22156	Here?
22156	How about sheet- lightning?
22156	How am I going to get Lassie out?
22156	How can I tell them apart on a photograph plate, sir?
22156	How can it be anything else?
22156	How can you tell that?
22156	How could we get them made?
22156	How did he succeed?
22156	How did you get it, Dan''l?
22156	How did you get left behind, anyhow?
22156	How did you get out, then?
22156	How do you know?
22156	How do you know?
22156	How do you know?
22156	How does she make it?
22156	How have you been making it?
22156	How long is it, Ross?
22156	How many kinds of clouds does the Weather Bureau name?
22156	How many kites did they use?
22156	How many pairs of shoes have you got?
22156	How near?
22156	How was that?
22156	How''s that?
22156	How, Dan''l?
22156	How, Mr. Levin? 22156 How?"
22156	Howdy, Ross,came the greeting in reply,"all your folks safe?"
22156	I had n''t thought of it,Ross answered,"but it does seem as if he were up against it, does n''t it?"
22156	I''m not a bit sure,said Ross as he patted the dog,"whether it was Anton or the pups that you wanted me to rescue, eh?
22156	I''ve been wondering,said Anton, thoughtfully,"what makes snow- flakes take those shapes?
22156	I''ve been wondering,said Anton,"how you can find out that it''s so cold high up in the air if no one can live up there?"
22156	In the West Indies?
22156	Is it all right for to- day?
22156	Is it just the rain that makes floods?
22156	Is it right over my head, Dan''l?
22156	Is it steady or veering?
22156	Is it the difference between a good conductor and a bad one that makes people put up lightning- rods?
22156	Is n''t hail just frozen rain?
22156	Is thar more''n one kind of time?
22156	Is that high as compared with other countries?
22156	Is that the crack that makes a train bump?
22156	Is that why muggy days are so uncomfortable?
22156	Is the house still standing?
22156	Is there always a cyclone before a cold wave?
22156	Is there any place in the United States without clouds?
22156	Is this hyar another of your contraptions to tell what the weather''s goin''to be like the year after next?
22156	It has n''t knocked yet, Dan''l, has it?
22156	It settles in regular shapes, does n''t it?
22156	It''s evaporation that puts water into the air, is n''t it, sir?
22156	Just how does the Weather Bureau come in,asked Ross,"the rainfall?"
22156	Kites? 22156 Levin been talking to you about Anton, Bob?"
22156	Longer than the Amazon?
22156	Make a Weather Bureau of our own, Mr. Levin? 22156 Marooned?
22156	Mr. Levin,he said,"can you spare me for a bit?
22156	Now what was the temperature here yesterday morning, Anton?
22156	Of course,agreed Ross,"but what has that got to do with it?"
22156	One of the boys?
22156	Roads in the air?
22156	Scared, Anton?
22156	Sent it?
22156	So you did save it, eh?
22156	So, if you walked a long way east, you''d see the sun quicker, would n''t you?
22156	Suppose it were done, that way, Mr. Levin,put in Anton,"would that settle it all?"
22156	Suppose you could figure all those things out, could n''t you foretell the weather, then?
22156	Suppose you had a pea on your head, it would n''t be heavy to carry, would it?
22156	Suppose you sunk that wall, away down deep, below the level of the bottom of the river?
22156	That was the worst ever, was n''t it, sir?
22156	That''s what the dredges are for, is n''t it?
22156	The chap who used to be with the Weather Bureau, you mean?
22156	Then what are the fires for?
22156	Then what shall we do, sir?
22156	Then you think that heating an orchard will save the fruit?
22156	Then you were with him, were n''t you?
22156	There is, eh?
22156	There is? 22156 They do look pretty far apart, do n''t they?"
22156	They''re muddy, are n''t they?
22156	Thirty- four years,said the Forecaster thoughtfully;"that would be in 1883, would n''t it?
22156	Those are n''t the thunder clouds, sir, are they?
22156	To the eastward? 22156 Was it Rex who brought you here?"
22156	We can, ca n''t we?
22156	Well, boys,he said,"what are you after?
22156	Well, that''s prophesying, is n''t it?
22156	Well, what if he did?
22156	Well?
22156	Well?
22156	Well?
22156	Were n''t you afraid of being killed?
22156	What are St. Elmo''s fires?
22156	What are they, sir?
22156	What are those little balls?
22156	What are you going to build that wall on? 22156 What are you going to do with all the little streams that flow into the Mississippi?
22156	What are you going to do, Tom?
22156	What can a chap do?
22156	What could the rest of us do?
22156	What could we do?
22156	What do I do, sir?
22156	What do you mean, Anton?
22156	What do you suppose we can do?
22156	What do you want, coming to my house at this hour of the night?
22156	What does it look like?
22156	What fo''makes that shorter?
22156	What for?
22156	What in blazes are you trying to photograph?
22156	What is it, Dan''l?
22156	What is it?
22156	What kind of a job?
22156	What kind of a motto, sir?
22156	What on earth have you got there, Dan''l?
22156	What sort of things, sir?
22156	What time was the shooting?
22156	What was it this morning?
22156	What was that, Mr. Levin? 22156 What''ll you do?"
22156	What''s that contrivance you''ve got on your camera stand, anyway?
22156	What''s that got to do with weather?
22156	What''s the barometer?
22156	What''s the dew- point, sir?
22156	What''s the direction of the wind, Tom?
22156	What''s the good of that?
22156	What''s the good of that?
22156	What''s the highest flight that ever was made?
22156	What''s the idea of that?
22156	What''s up, Ross?
22156	What''s wrong?
22156	What- all happens to that yar hour?
22156	What?
22156	Where are you going, old boy?
22156	Where did it begin, sir?
22156	Where is he?
22156	Where will we get the wire?
22156	Where will you put it, boys?
22156	Where''s Rex now,queried Anton,"down in our old boat?"
22156	Whew,whistled the farmer,"and is that on its way here?"
22156	Which did you wear this afternoon?
22156	Who do you suppose drew them?
22156	Who is it?
22156	Who was that, sir?
22156	Who''d have thought o''that, now?
22156	Who''s that, sir?
22156	Who''s that? 22156 Who- all fixed it up that way?"
22156	Why did n''t you tell a fellow?
22156	Why do n''t you boys make it easy for him?
22156	Why do n''t you fix it so that you wo n''t have to measure the length of the shadow every day?
22156	Why do you?
22156	Why is annything blue?
22156	Why is it such a hard job?
22156	Why is it,asked the younger boy,"that there''s more rain one year than another?"
22156	Why not, Dan''l?
22156	Why not?
22156	Why were n''t we under bare poles,you asks?
22156	Why, Father?
22156	Why, sir?
22156	Why, sir?
22156	Why?
22156	Why?
22156	Why?
22156	Will that wire hold it, sir?
22156	Without any measuring as to length?
22156	Without you?
22156	Wo n''t you show us?
22156	Wondering if any one was going to come for you?
22156	Would we?
22156	Yes,Ross agreed, but uneasily, for he was watching the sky steadily,"but do you think we''ll ever be able to do it?"
22156	Yes?
22156	Yes?
22156	Yo''not fooling?
22156	You knew that the sun- dial is one of the official emblems of the United States?
22156	You know that printing- press of mine?
22156	You mean because CÃ ¦ sar is a negro?
22156	You mean both in summer and winter?
22156	You mean by smoking them?
22156	You mean her crystal?
22156	You mean that every day''s weather map is different?
22156	You mean the one you printed the pirate flags on, Fred?
22156	You mean to say that the weather at the North Pole and at the equator has anything to do with our weather here?
22156	You mean to say that there are different layers of wind?
22156	You mean, sir, that a red sunset and a gray sunrise really tell that the weather is going to be fine?
22156	You really want to know why rain comes? 22156 You spoke of the''roads in the air,''sir,"put in Ross,"how many are there?"
22156	You''re not hurt?
22156	You''ve got plenty of wind at your place, Lee, have n''t you?
22156	You''ve often heard the crackling of a near- by thunder compared to an irregular volley of rifles, have n''t you?
22156	Your temperature?
22156	--_Marine Journal._ THE BOY WITH THE U. S. MAIL How much do you know of the working of the vast and wonderful Post Office Department?
22156	Abner?"
22156	Again-- Why should n''t he?
22156	And the wind, Tom?"
22156	And what do you suppose the circus folk did?"
22156	And what was the wind, Tom?"
22156	And why does a bar of iron sink through water and not through earth?"
22156	And, Mr. Lovell, can I use the wireless for a minute?"
22156	And, talking of grub, Anton, are n''t you hungry?"
22156	Another man?"
22156	Are these like that?"
22156	As the only thing that would make them expand would be the heat, you could measure the heat that way, could n''t you?"
22156	As there would n''t be anywhere for it to go except through the tube, it would shoot up the tube, would n''t it?"
22156	Besides, Ross, where would you build this wall?
22156	Boys,"he said, breaking off suddenly,"why does a stick float in water when it falls in air?"
22156	But I do n''t quite see what he can do?"
22156	But do you know what mud is?"
22156	But how about a cold wave?
22156	But how can you- all tell when the rain began?"
22156	But is that always the same?"
22156	But who''s to have charge of the kite- flying?"
22156	But, look here, Anton, how are we going to get you out?
22156	CHAPTER III PUTTING THE SUN TO WORK"Fo''the land''s sake, Mistah Anton, what fo''yo''puttin''up that pole on the grass?"
22156	CHAPTER IV THE MASSACRE OF AN ARMY"Where''s the boss?"
22156	Ca n''t you tell what I brought you here for?"
22156	Can you and will you take it?"
22156	Can you figure that out in the same way?"
22156	Can you?"
22156	Dan''l, do you suppose there''s a pail of whitewash in the barn?"
22156	Did we pump without stoppin''?
22156	Did we stop?
22156	Did you happen to notice, Ralph, whether there was a halo round the sun when you took this?"
22156	Did you know that, Ross?
22156	Do n''t you have to pass an examination, or something?"
22156	Do you know how to do that?"
22156	Do you know, Bob?"
22156	Do you mind if I go ahead and see?"
22156	Do you see that layer of cirro- stratus clouds?"
22156	Does n''t that prove he could n''t have been out after the rain started?"
22156	First of all, why is the sky blue?"
22156	From what house in Galveston had this floated, to find a resting- place on the floor of an un- roofed and un- walled negro''s cabin?
22156	Had the boat suffered in the careening of the house?
22156	Has anything happened?"
22156	Have any of you ever seen a weather kite?"
22156	Have n''t you sometimes seen, after a cold night, a lot of needles shooting out from the sides from a puddle?"
22156	Have you any prints of them?"
22156	Have you enlarged your staff, Fred?"
22156	He had reached the house, but how was Anton to be rescued?
22156	How about it, Bob?"
22156	How about it, boys?
22156	How am I going to get it?"
22156	How cold?"
22156	How much weight of air do you suppose you''re carrying, Anton?"
22156	How would you reel the kite home?
22156	How''s that?"
22156	I suppose you think a cyclone is some kind of a whirlwind, a particularly violent storm, eh?"
22156	I suppose you''ve heard the story of the American sun- dial motto?"
22156	I wonder why?"
22156	I''ll send one of the roustabouts with you, if you like?"
22156	If most of the thunder storms travel from the west, where does this banging come in?"
22156	If you saw his house on fire, Fred, you would n''t hesitate to tell Jed Tighe, would you?"
22156	Is n''t there a rhyme about clouds and towers, Dan''l?"
22156	Is that clear?"
22156	Is that it?"
22156	Is that what you mean?"
22156	Is that you?
22156	It''s a little short, is n''t it?"
22156	Just how, sir?"
22156	Levin?"
22156	Levin?"
22156	Levin?"
22156	Levin?"
22156	Levin?"
22156	Levin?"
22156	Levin?"
22156	Levin?"
22156	Levin?"
22156	Levin?"
22156	Levin?"
22156	Levin?"
22156	Levin?"
22156	Like Franklin''s?"
22156	Man against the hurricane-- which would win?
22156	Now, boys,"he continued,"what kind of banks has the river around here, rock or earth?"
22156	Now, where''s that crutch?"
22156	On all sides of the''low''there is rain, and you remember how it rained here, yesterday morning, early?"
22156	On the ground?"
22156	Putting up a flag- pole?
22156	Reassured, Ross turned to his companion, and asked:"What makes tornadoes, Anton?"
22156	Right on the bank?"
22156	See?"
22156	Shall we try a flight to- day?"
22156	Should he venture?
22156	So, if you allow for sag and so forth, you''d have to put out eight or nine thousand feet of wire to reach a mile, would n''t you?"
22156	Somebody else in trouble, eh?"
22156	Stood there all by itself, sharply gleaming against the black ground-- What was that lying on the farther side of it?
22156	The clocks change four times in the United States, do n''t they, Ross?"
22156	The sun rises in the east, does n''t it?"
22156	The wind, Tom?"
22156	This was rather a poser, but finally Anton said slowly,"It''s a mixture of earth and water, is n''t it?"
22156	Tom, how''s the wind?"
22156	True, the great sea- wall had since been built to protect the town, but would it stand?
22156	Was the door into the hall open?
22156	Well, Tom, what is it?"
22156	What I''m thinking is this-- why could n''t Anton be taken in hand and taught to fit himself for the Weather Bureau?
22156	What are we going to do?"
22156	What are you after?
22156	What do you think we''d better do?"
22156	What is it?"
22156	What kind of a figure will that make?"
22156	What more proof could any one want?
22156	What wages do you want?"
22156	What was the wind going to be like?

36691	A lens, then, answers the purpose equally well, either for magnifying or diminishing objects?
36691	Am I not right, Mrs. B.?
36691	And pray, Mrs. B., when my brothers play at_ see- saw_, is not the plank on which they ride, a kind of lever?
36691	And pray, at what rate do we move?
36691	And why is it not the case with the shadows of terrestrial objects?
36691	B._ And now that I pour more water into the bason, why does the paper rise?
36691	B._ Bodies thus projected, you observe, describe a curve- line in their descent; can you account for that?
36691	B._ Caroline, what would be the effect, were the body supported in any other single point?
36691	B._ Did it ever occur to you as extraordinary, that you never beheld your own face?
36691	B._ Do you not know, that, in the course of time, all the water which sinks into the ground, rises out of it again?
36691	B._ Do you understand what is meant by the level, or equilibrium of fluids?
36691	B._ Have we not a similar proof of the earth''s motion, in the apparent motion of the sun and stars?
36691	B._ Is nature less pleasing for being coloured, as well as illumined, by the rays of light?
36691	B._ Now tell me, do you think that your brother could raise you as easily without the aid of a lever?
36691	B._ Suppose there were but one body existing in universal space, what would its weight be?
36691	B._ Very well; and what number of degrees are there from the equator to one of the poles?
36691	B._ Very well; and where is the centre of gravity of this pair of scales?
36691	B._ Well, my dear, pray what is this weighty objection?
36691	B._ What is that which makes the gilt buttons on your brothers coat shine?
36691	B._ What will you say, my dear, when I tell you, that these two forces are not, in fact, so proportioned as to produce circular motion in the earth?
36691	B._ Why should you think so?
36691	B._ Would it not have been better to have answered with a moment''s reflection, Caroline?
36691	B._ You mean, I suppose, in other words to inquire whether two lines which are perpendicular to the earth, are parallel to each other?
36691	Before the time of Newton, was not the earth supposed to be in the centre of the system, and the sun, moon, and stars to revolve round it?
36691	But I do not see how this accounts for the motion of the secondary, round the primary planets, in preference to moving round the sun?
36691	But I do not understand what makes the planets shine?
36691	But I do not understand why the longest arm of the lever should not be in equilibrium with the other?
36691	But does that chair, at the further end of the room, form an image on my retina, much smaller than this which is close to me?
36691	But in the earth''s revolution round the sun, every part must move with equal velocity?
36691	But is not height also a dimension of extension?
36691	But is the air a body of the same nature as other bodies?
36691	But of what use then is a fixed pulley in mechanics?
36691	But pray what is it that produces the elasticity of bodies?
36691	But this microscope can be used only for transparent objects; as the light must pass through them, to form the image on the wall?
36691	But what is a sonorous body, Mrs. B.?
36691	But what sort of weather must those people have, who live on the spot, where these winds meet and interfere?
36691	But why is this defect remedied by bringing the object nearer to the eye, as we find to be the case with short- sighted people?
36691	But would the same effect be produced, if the spout and the pot, were of equal dimensions?
36691	But, Mrs. B., if attraction is a property essential to matter, weight must be so likewise; for how can one exist without the other?
36691	But, Mrs. B., if the air is a real body, is it not also subjected to the laws of gravity?
36691	But, Mrs. B., what is the reason that the green leaves, are of a brighter blue than the rose?
36691	But, Mrs. B., why does not the sun produce tides, as well as the moon; for its attraction is greater than that of the moon?
36691	But, pray, do they see the earth under all the changes, which the moon exhibits to us?
36691	Can you form any idea what this loss will be?
36691	Can you tell me now how much more light we enjoy than Saturn?
36691	Can you tell me now, how the earth will move?
36691	Can you tell me, Caroline, how many miles you will have travelled, if your velocity is three miles an hour, and you travel six hours?
36691	Can you tell me, Caroline, why objects at a distance, appear smaller than they really are?
36691	Caroline, place yourself in the direction of the reflected rays, and tell me whether you do not see Emily''s image in the glass?
36691	Did you ever notice the swingle- tree of a carriage to which the horses are attached when drawing?
36691	Did you ever observe that a lever describes the arc of a circle in its motion?
36691	Did you see, Emily, the feather appeared as heavy as the guinea?
36691	Do not rivers also, derive their source from springs?
36691	Do not the extremities of the vanes of a windmill move over a much greater space, than the parts nearest the axis of motion?
36691	Do we not every day see heavy bodies fall quickly, and light bodies slowly?
36691	Do you know how that is contrived?
36691	Do you perceive the water rising in this small glass tube, above its level in the goblet of water, into which I have put one end of it?
36691	Do you recollect those beautiful lines of Milton?
36691	Do you see the flower painted at the bottom of the inside of this tea- cup?
36691	Do you understand this, Caroline?
36691	Do you understand this?
36691	Do you understand this?
36691	Do you understand what an angle is?
36691	Does not this prove that I see the objects themselves?
36691	Does not this table weigh heavier than this book; and, if one thing weighs heavier than another, must there not be such a thing as weight?
36691	Does that house appear to you much smaller, than when you are close to it?
36691	Emily, do you recollect the names of the general properties of bodies?
36691	Have you ever seen your brother move a snow- ball by means of a strong stick, when it became too heavy for him to move without assistance?
36691	Have you never observed a black dress, to be warmer than a white one?
36691	How may this be effected?
36691	I should have thought it would have been just the contrary, for land is certainly a more dense body than water?
36691	I thought that it was impossible to produce perpetual motion?
36691	I told her that it required no support; she then inquired why it did not fall as every thing else did?
36691	I will show you another instance, of the weight of the atmosphere, which I think will please you: you know what a barometer is?
36691	I wonder how the idea of gravitation could first have occurred to sir Isaac Newton?
36691	If you weigh a piece of gold, in a glass of water, will not the gold displace just as much water, as is equal to its own bulk?
36691	Is not a fluid level when its surface is smooth and flat, as is the case with all fluids, when in a state of rest?
36691	Is not that a strong argument against your theory?
36691	Is the firm adhesion of the two plates merely owing to the attraction of cohesion?
36691	Let us now fix it on the air pump, and exhaust the air from underneath it-- you will not be alarmed if you hear a noise?
36691	Let us suppose a body to be struck by two equal forces in opposite directions, how will it move?
36691	Look at that large sheet of water; can you tell why the sun appears to shine on one part of it only?
36691	Look at this bason of water; why does the piece of paper which I throw into it float on the surface?
36691	Now Emily, it is your turn; what is_ accelerated motion_?
36691	Now Emily, you may tell me exactly how many degrees are contained in a meridian?
36691	Now I will lay it on the surface of the water; but there it sinks a little-- what is the reason of that, Mrs. B.?
36691	Now can you tell me what is_ retarded motion_?
36691	Now can you tell me whether the air is heavier, in wet, or in dry weather?
36691	Now that I have removed the mirror out of the influence of the sun''s rays, if I place a burning taper in the focus, how will its light be reflected?
36691	Now, Emily, let me hear if you can explain how the gravity of bodies is modified by the effect of the air?
36691	Now, Mrs. B., will you let me fill the tube, by pouring water into the goblet?
36691	Now, can you tell me in what direction the three rays, A B, C D, E F, will be reflected?
36691	Now, if the air were destitute of weight, how could it support other bodies, or retard their fall?
36691	Suppose the two forces are unequal, but do not act on the ball in the direction of a right angle, but in that of an acute angle, what will result?
36691	Tell me, Caroline, what do you understand by the word motion?
36691	That part of the sheet of water, over which the trees cast a shadow, by what light do you see it?
36691	The power of the screw, complicated as it appears, is referable to one of the most simple of the mechanical powers; which of them do you think it is?
36691	The spot of light is extremely brilliant, but the paper does not burn?
36691	Those who live to the north of it, experience a north wind; those to the south, a south wind:--do you comprehend this?
36691	To the inhabitants of the other planets, then, we must appear as a little star?
36691	Well, Caroline, have you ascertained what kind of pump you have in your garden?
36691	Well, you will perhaps be surprised to hear that the gold will weigh less in water, than it did out of it?
36691	What is it that occasions the fall of this book, when I no longer support it?
36691	What is the reason that the great quantity of rain which falls upon the earth and sinks into it, does not, in the course of time, injure its solidity?
36691	What reason is there to regret, that she does not wear it when she is invisible?
36691	What substance do you think would be best calculated to answer this end?
36691	What then ensues?
36691	What, Mrs. B., are we all as black as negroes in the dark?
36691	Why then should these enormous globes daily traverse such a prodigious space, merely to prevent the necessity of our earth''s revolving on its axis?
36691	Will the wagon now be upset?
36691	With what do you choose to make the experiment?
36691	Would it not be clearer, if the opening in the shutter were enlarged, so as to admit more light?
36691	Would you call wood, and chalk, light or heavy bodies?
36691	You both, I suppose, have seen a pulley?
36691	You conceive that a body having length, breadth and depth, can not be without form, either symmetrical or irregular?
36691	You know the old saying, that a pound of feathers, is as heavy as a pound of lead?
36691	You recollect that law in mechanics?
36691	You see none of the balls except the last, appear to move, this flies off as far as the first ball fell; can you explain this?
36691	_ Caroline._ And from whence arises this difference, between elastic, and non- elastic fluids?
36691	_ Caroline._ And from whence proceeds the pressure of fluids upwards?
36691	_ Caroline._ And of what nature are the other two kinds of levers?
36691	_ Caroline._ And should not the sun appear smaller in summer, when it is so much further from us?
36691	_ Caroline._ And what is this singular circumstance, which seems to disturb the laws of nature?
36691	_ Caroline._ And, pray, why is the sky of a blue colour?
36691	_ Caroline._ Are not comets, in some respects similar to planets?
36691	_ Caroline._ Are you sure that it is not the glass, which covers the bell, that prevents our hearing it?
36691	_ Caroline._ As the three rays are parallel, why are they not all perpendicular to the mirror?
36691	_ Caroline._ But a top generally has a motion forwards besides its spinning motion; and then no point within it can be at rest?
36691	_ Caroline._ But do not the primary planets, sometimes eclipse the sun from each other, as they pass round in their orbits?
36691	_ Caroline._ But does not the attraction of the denser medium affect the ray before it touches it?
36691	_ Caroline._ But how are we to judge of the quantity of matter contained in a certain bulk?
36691	_ Caroline._ But if a machine is made of polished metal, as a watch for instance, the friction must be very trifling?
36691	_ Caroline._ But if it were possible to relieve me from the weight of the atmosphere, should I not feel more light and agile?
36691	_ Caroline._ But if we see all terrestrial objects by reflected light,( as we do the moon,) why do they appear so bright and luminous?
36691	_ Caroline._ But is it not very easy to find both the latitude and longitude of any place by a map or globe?
36691	_ Caroline._ But red and green mixed together, do not produce yellow?
36691	_ Caroline._ But since an image must be formed on the retina of each of our eyes, why do we not see objects double?
36691	_ Caroline._ But surely there can be no pores in ivory and metals, Mrs. B.; how then can they be susceptible of compression?
36691	_ Caroline._ But there is a spring in our grounds, which more frequently flows in dry, than in wet weather; how is that to be accounted for?
36691	_ Caroline._ But unless you can see the sun, how can you take its altitude?
36691	_ Caroline._ But, Mrs. B., if we see only the image of objects, why do we not see them reversed, as you showed us they were, in the camera obscura?
36691	_ Caroline._ But, Mrs. B., the grass is green, and the flowers are coloured, whether in the dark, or exposed to the light?
36691	_ Caroline._ But, if the sun really shines on every part of that sheet of water, why does not every part of it, reflect rays to my eyes?
36691	_ Caroline._ By friction, do you mean one part of the machine rubbing against another part contiguous to it?
36691	_ Caroline._ Do not the vanes of a windmill represent a wheel, Mrs. B.?
36691	_ Caroline._ Do you mean to say, that the action of the body which strikes, is returned with equal force by the body which receives the blow?
36691	_ Caroline._ Does attraction act on water more powerfully than on land?
36691	_ Caroline._ Has the experiment been made in these different situations?
36691	_ Caroline._ How is that possible?
36691	_ Caroline._ I can not conceive how these colours, mixed together, can become white?
36691	_ Caroline._ I have heard so, but do you not think such an opinion too great a stretch of the imagination?
36691	_ Caroline._ I should then imagine that it would fall, quicker than it rose?
36691	_ Caroline._ I thought that perpendicularly meant either directly upwards or downwards?
36691	_ Caroline._ I understand that perfectly; but what is the meaning of the other point B?
36691	_ Caroline._ I understand that very well; and is not this the reason that oars appear bent in the water?
36691	_ Caroline._ In drawing a view from nature, it seems that we do not copy the real objects, but the image they form on the retina of our eyes?
36691	_ Caroline._ In that case we can not see her, for she must rise in the day time?
36691	_ Caroline._ In the torrid zone, then, I hope you will grant that the moon is immediately over, or opposite the spots where it is high water?
36691	_ Caroline._ Is it for this reason that wheels are greased, and the locks and hinges of doors oiled?
36691	_ Caroline._ Is light then a substance composed of particles, like other bodies?
36691	_ Caroline._ Is not sound produced by solid bodies?
36691	_ Caroline._ My head then moves faster than my feet; and upon the summit of a mountain, we are carried round quicker than in a valley?
36691	_ Caroline._ On what then can we rely, for do we not receive all our ideas through the medium of our senses?
36691	_ Caroline._ Pray by what means is this receiver exhausted of its air?
36691	_ Caroline._ Pray what are the planets?
36691	_ Caroline._ Pray what is the distinction between a fluid and a liquid?
36691	_ Caroline._ Pray, Mrs. B., do the two scales of a balance hang parallel to each other?
36691	_ Caroline._ Pray, Mrs. B., is not the leather, which covers the opening, in the lower board of a pair of bellows, a kind of valve?
36691	_ Caroline._ Pray, Mrs. B., is not the thermometer constructed on the same principles as the barometer?
36691	_ Caroline._ Pray, what is the meaning of focus?
36691	_ Caroline._ That is very clear, but supposing the two forces to be unequal, that the force X, for instance, be twice as great as the force Y?
36691	_ Caroline._ The axle of a grindstone, is then the axis of its motion; but is the centre of motion always in the middle of a body?
36691	_ Caroline._ The weight and the fulcrum have here changed places; and what advantage is gained by this kind of lever?
36691	_ Caroline._ Then the larger the wheel, in proportion to the axle, the greater must be its effect?
36691	_ Caroline._ Then the more distant planets, move much slower in their orbits; for their projectile force must be proportioned to that of attraction?
36691	_ Caroline._ Then why does it not, like all other bodies, fall to the ground?
36691	_ Caroline._ There must be a great number of eclipses in the distant planets, which have so many moons?
36691	_ Caroline._ This explanation of the monsoons is very curious; but what does their breaking up mean?
36691	_ Caroline._ This figure renders it very clear: then two bodies can not fall to the earth in parallel lines?
36691	_ Caroline._ This is extremely curious; but why should brown paper, absorb more rays, than white paper?
36691	_ Caroline._ This rose: look at it, Mrs. B., and tell me whether it is possible to deprive it of its beautiful colour?
36691	_ Caroline._ What colour do you suppose them to be, then, in the dark?
36691	_ Caroline._ What is the reason that articles which are blue, often appear green, by candle- light?
36691	_ Caroline._ What, the pendulum of a clock?
36691	_ Caroline._ When a stick is poised on the tip of the finger, is it not by supporting its centre of gravity?
36691	_ Caroline._ Why do you observe the temperature of the room, in estimating the weight of the air?
36691	_ Caroline._ Why do you wet the bladder first?
36691	_ Caroline._ Why not quite as high?
36691	_ Caroline._ Why then does one side of the house appear to be in sunshine, and the other in shade?
36691	_ Caroline._ Why then does the air feel so heavy, in bad weather?
36691	_ Caroline._ Why then should not mirrors be made simply of mercury?
36691	_ Caroline._ You do not mean to say, that we see only the representation of the object, which is painted on the retina, and not the object itself?
36691	_ Emily._ And are not fountains, of the nature of springs?
36691	_ Emily._ And at what height, will the weight of the atmosphere sustain the mercury?
36691	_ Emily._ And for what reason?
36691	_ Emily._ And how do you ascertain the specific gravity of fluids?
36691	_ Emily._ And how do you know which colours bodies have a tendency to reflect, or which to absorb?
36691	_ Emily._ And how much longer is the sidereal, than the solar year?
36691	_ Emily._ And is it thus, that the picture of objects, is painted on the retina of the eye?
36691	_ Emily._ And is light, in its reflection, governed by the same laws, as solid, elastic bodies?
36691	_ Emily._ And is no inconvenience experienced, from the thinness of the air, in such elevated situations?
36691	_ Emily._ And is there any considerable difference between solar time, and true time?
36691	_ Emily._ And may we not say that gravity is the force which occasions the fall of bodies?
36691	_ Emily._ And of what length is a degree of latitude?
36691	_ Emily._ And pray, have the other planets the same vicissitudes of seasons, as the earth?
36691	_ Emily._ And when shall we learn them?
36691	_ Emily._ And yet a pair of scales, hanging perpendicular to the earth, appear parallel?
36691	_ Emily._ Are not the eclipses of the sun produced by the moon passing between the sun and the earth?
36691	_ Emily._ Are the trumpets used as musical instruments, also constructed on this principle?
36691	_ Emily._ But are there not some bodies which have exactly the same specific gravity as water?
36691	_ Emily._ But can we not ascertain the weight of a small quantity of air?
36691	_ Emily._ But do not the rays which are projected in different directions, and cross each other, interfere, and impede each other''s course?
36691	_ Emily._ But does not every part of the earth move with the same velocity?
36691	_ Emily._ But each set of these irregular vibrations, if repeated alone, and at equal intervals, would, I suppose, produce a musical tone?
36691	_ Emily._ But have we not just seen the ray of light, in its passage from the sun to the mirror, and its reflections?
36691	_ Emily._ But how do they contrive to regulate their time in the equatorial and polar regions?
36691	_ Emily._ But how does a prism separate these coloured rays?
36691	_ Emily._ But if the air moves backwards, as well as forwards, how can its motion extend so as to convey sound to a distance?
36691	_ Emily._ But if the tube through which the water rises be smooth, can there be any friction?
36691	_ Emily._ But is that side of the house yonder, which appears to be in shadow, really illuminated by the sun, and its rays reflected another way?
36691	_ Emily._ But may it not be objected to pulleys, that a longer time is required to raise a weight by their aid, than without it?
36691	_ Emily._ But since this watery vapour is lighter than the air, why does it not continue to rise; and why does it unite again, to form clouds?
36691	_ Emily._ But the quantity must really be diminished?
36691	_ Emily._ But they may see our sun as we do theirs, in appearance a fixed star?
36691	_ Emily._ But were you to penetrate deep into the earth, would gravity increase as you approached the centre?
36691	_ Emily._ Can a mirror form more than one focus, by reflecting rays?
36691	_ Emily._ Can it be the attraction of the earth?
36691	_ Emily._ Can not the power of the screw be increased also, by lengthening the lever attached to the nut?
36691	_ Emily._ Does not the air pump, which you used in the experiments, on pneumatics, operate upon the same principles as the sucking pump?
36691	_ Emily._ How can the angles be equal, while the lines which compose them are of unequal length?
36691	_ Emily._ How is it that the rain water does not continue to descend by its gravity, instead of collecting together, and forming springs?
36691	_ Emily._ I have heard much of the violent tempests, occasioned by the breaking up of the monsoons; are not they also regular trade- winds?
36691	_ Emily._ I think I can trace a consequence from these different situations of the earth; are not they the cause of summer and winter?
36691	_ Emily._ I thought that the earth performed one complete revolution in its orbit, every year; what is the reason of this variation?
36691	_ Emily._ I thought the sun had no motion?
36691	_ Emily._ If so, how is it possible to prove that they are endowed with this power?
36691	_ Emily._ If the ecliptic relates only to the heavens, why is it described upon the terrestrial globe?
36691	_ Emily._ If the fixed stars are suns, with planets revolving round them, why should we not see those planets as well as their suns?
36691	_ Emily._ If you throw a stone perpendicularly upwards, is it not the same length of time in ascending, that it is in descending?
36691	_ Emily._ If, then, we are driven by one power, and drawn by the other to this centre of destruction, how is it possible for us to escape?
36691	_ Emily._ In what direction does the water attract the ray?
36691	_ Emily._ Is it not because the vicinity of the primary planets, renders their attraction stronger than that of the sun?
36691	_ Emily._ Is it not in consequence of refraction, that the glasses in common spectacles, magnify objects seen through them?
36691	_ Emily._ Is it not similar to the syringe, or squirt, with which you first draw in, and then force out water?
36691	_ Emily._ Is it not surprising that nature should have furnished us with such disadvantageous levers?
36691	_ Emily._ Is there then no difference between rain water, and spring water?
36691	_ Emily._ It would then be much more difficult to work a machine under water than in the air?
36691	_ Emily._ Oh yes; I see it slowly creeping up the tube, but now it is stationary: will it rise no higher?
36691	_ Emily._ Pray what is the reason that the tide is three- quarters of an hour later every day?
36691	_ Emily._ Pray, Mrs. B., by what rule do you estimate the power of the screw?
36691	_ Emily._ Pray, Mrs. B., can not the sun''s rays be collected to a focus by a lens, in the same manner as they are by a concave mirror?
36691	_ Emily._ Pray, Mrs. B., what are the constellations?
36691	_ Emily._ Pray, do not glass windows, refract the light?
36691	_ Emily._ Pray, how is the sound of an echo produced?
36691	_ Emily._ Pray, is not a magic lanthorn constructed on the same principles?
36691	_ Emily._ Pray, what is the reason that we can not see an object distinctly, if we place it very near to the eye?
36691	_ Emily._ Pray, why does the sun appear red, through a fog?
36691	_ Emily._ Since dark bodies, absorb more solar rays than light ones, the former should sooner be heated if exposed to the sun?
36691	_ Emily._ Since it is impossible, in this case, to make the object approach the eye, can not we by means of a lens bring an image of it, nearer to us?
36691	_ Emily._ Since the air is a gravitating fluid, is it not affected by the attraction of the moon and the sun, in the same manner as the waters?
36691	_ Emily._ So it appears: yet I have seen a cylinder of wood roll up a slope; how is that contrived?
36691	_ Emily._ Such as a piece of broken china, or glass?
36691	_ Emily._ That is very extraordinary; and how then do you account for the heat being greatest, when we are most distant from the sun?
36691	_ Emily._ The attraction of cohesion is then, I suppose, less powerful in fluids, than in solids?
36691	_ Emily._ The hinges represent the fulcrum, our hands the power applied to the other end of the lever; but where is the weight to be moved?
36691	_ Emily._ The moon, Mrs. B., appears to move in a different direction, and in a different manner from the stars?
36691	_ Emily._ Then when we want to lift a great weight, we must fasten it to the shortest arm of a lever, and apply our strength to the longest arm?
36691	_ Emily._ There are then other kinds of air, besides the atmosphere?
36691	_ Emily._ These divergent rays, issuing from a single point, I believe you told us, were called a pencil of rays?
36691	_ Emily._ This is one of the advantages of carriage wheels, is it not?
36691	_ Emily._ To what extent must I open the compasses?
36691	_ Emily._ What does that mean?
36691	_ Emily._ When the moon eclipses the sun to us, we must be eclipsed to the moon?
36691	_ Emily._ When water runs out of the side of a vessel, is it not owing to the weight of the water, above the opening?
36691	_ Emily._ When you speak of the sun''s motion, you mean, I suppose, his apparent motion, produced by the diurnal motion of the earth?
36691	_ Emily._ Yet they actually touch each other?
36691	_ Emily._ You astonish me: surely you do not mean to say that large bodies attract each other?
36691	_ Emily._ You hold the wire awry, I suppose, in order to show that the axis of the earth is not upright?
36691	and are colours less beautiful, for being accidental, rather than essential properties of bodies?
36691	and how does she accompany the earth?
36691	and were to strike the ball A, at the same instant; would it not move?
36691	and what their uses?
36691	and why not?
36691	are, I suppose, less powerful in their refractions?
36691	have bodies no weight?
36691	how can you put the two bodies of different weight within the glass, without admitting the air?
36691	how could that answer the purpose?
36691	is there another species of gravity, with which we are not yet acquainted?
36691	make a light body balance a heavy one?
36691	must I not exert ten times as much strength to draw the larger one to me, in the same space of time, as is required for the smaller one?
36691	operate?
36691	represent, and what are its extremities called?
36691	that is an excellent thought, Emily; will you stand the test, Mrs. B.?
36691	to what height will it ascend, and what will it form?
36691	weight with ten times the force that it does that of 100 lbs.?
36691	what is the inclination of her orbit?
36691	what would result?
36691	when I ring this little bell, is it the air that sounds, and not the bell?
