“ For more than ten years it might be almost said that a sleepless watch of the heavens has been kept up by an all-seeing photographic eye, with an accuracy of which the world has hardly had a conception. The completeness with which its work has been done has recently been shown in a striking way. Our readers are doubtless acquainted with the singular character of the minor planet Eros, whose orbit passes through that of Mars, as one link of a chain passes through another, and which comes nearer the earth at certain times than any other celestial body, the moon excepted. ”

“ In education no such sudden revolutions occur, and great changes are introduced by degrees without producing any commotion or any surprise. From the days of Erasmus and Rabelais, if not earlier, educational reformers have urged the importance of studying things rather than books about things, of cultivating the hand and eye as well as the mind, of training the perceptive powers, of cultivating a habit of observation and discrimination, and of developing the faculty of judgment. ”

“ Perhaps the simplest form of this craze is seen in the epidemic character of children’s games. At different times of the season different games completely fill the social consciousness of the child-world, so that for the moment there is no interest in any other game. New and interesting sports, such, for instance, as golf, often fill the social adult consciousness in the same way. Then there are social and literary fads, crazes in musical airs, fashions in dress, furniture, houses and carriages, without number. Crazes of all kinds have found a prolific soil in America. ”

“ The dimensions of the solar system are vast when compared with any terrestrial standard. A cannon shot going incessantly at its utmost speed would be a thousand years in crossing the orbit of Neptune from side to side. But vast as the dimensions are, they sink into insignificance when compared with the distance of the stars. Outside the solar system are spaces which, so far as we know, are absolutely void, save here and there a comet or a meteor, until we look far outside the region which a cannon shot would cross in a million of years. ”

“ A few far outshine the great mass of their companions. A greater number are of what we may call medium brightness; there is a yet larger number of fainter ones, and about one half of all those seen by a keen eye under favorable conditions are so near the limit of visibility as to escape ordinary notice. Moreover, those which we see are but an insignificant fraction of the number revealed by the telescope. The more we increase our optical power, the greater the number that come into view. How many millions may exist in the heavens it is scarcely possible even to guess. ”

“ May we not hope that as the applications of science to the arts enrich the alumni and friends of the Institute, they may help to make the road easy for their successors by devoting a part of their riches to the advancement of technical education? ”

“ Even now, what we measure in taking the photograph of a star is almost entirely the light in the more refrangible portions of the spectrum. It appears, therefore, that when a blue and a yellow star, equally bright to the naked eye, are photographed, the impression made on the negative by the blue star will be greater than that made by the yellow one. A distinction is therefore recognized between photographic and visual magnitudes.
The photographic magnitudes of the stars are now being investigated and catalogued on a scale even larger than that on which we have studied the visual magnitudes. ”

“ We learn from biology that the child is to some extent a recapitulation of the life of the race, passing through in his individual development the stages of race development. Physiologically speaking, the higher brain centers and the centers for association, which are late acquirements of the race, are last developed in the child. We are therefore not surprised to find that the child, like the savage and the hypnotic subject, is imitative, impulsive, non-reflective, incapable of much abstract thought, deliberation or reasoning, and that he acts with a view to immediate rather than remote ends. ”

“ The great advances in sanitary science in recent years have made bacteriology one of the most important, as well as one of the most practical, of the biological sciences, and the biologist has taken his place beside the chemist and the engineer in the study of the science and art of public sanitation. But bacteriology is of importance, not only in sanitary science, but also in its industrial relations. ”

“ It was the first school in the world to institute laboratory instruction in physics and chemistry to students in large classes as a part of the regular course of each candidate for a degree; the first to equip a mining and metallurgical laboratory for the instruction of students by actual treatment of ores in large quantities; the first to establish a laboratory for teaching the nature and uses of steam, and a laboratory for testing the strength of materials of construction in commercial sizes; and the first in America to establish a department of architecture. ”

“ The savage’s fear of demons and of unseen supernatural agencies lurking in every forest and moor now took hold of the modern world and turned the people, not into brutes and devils as we figuratively say, but simply into the original savages from which they came, whose basal instincts they still carried in their lower nervous centers, to be brought out under the influence of a social craze. ”

“ It has a tendency to be periodic, so that if it has slumbered for a considerable period a very slight cause is sufficient to awaken it. A mere boundary line in Venezuela, in which this country had but a remote interest, was sufficient a few years ago to excite this war spirit in a milder form, when a curious craze for a war with Great Britain flowed like a wave across this country. ”

“ These congresses may meet and discuss arbitration and perfect an international program, but they labor in vain, for they forget that social man has a double personality and that the personality that meets and deliberates in the peace congress is not the personality that, under the influence of the war craze, thrills with emotion and acts from ancient and deep rooted impulses and motives. ”

“ Indeed, the only important department of study which is found in such institutions, and for which no provision is made at the Institute, is that of ancient languages. The force of instruction in the department of general studies, leaving out of consideration the department of modern languages, comprises two professors, one associate professor, three assistant professors, one instructor and one assistant, a total of eight, probably a larger number than is found in any but the very largest colleges. ”

“ Whether one believes, with Lockyer, that the chemical ‘elements’ are disassociated by the sun’s heat into simpler substances or not, it is clear that very violent chemical reactions are in progress, and if we realize that the known chemical reactions increase in intensity with increase in temperature, it does not seem strange that at the sun’s temperature the reactions occurring should cause disturbances like those observed. ”

“ In fads and fashions of all kinds, the behavior of the social personality is different only in degree from that already described in the more serious epidemics. The law of imitation is the same, but there is less excitement and emotional disturbance and consequently a lesser paralysis of the higher mental faculties and a lesser return to barbaric impulses. Whereas the others may be called forms of social paranoia, these may be called forms of social monomania. A single idea fills the public mind, and as a result this idea is unduly exalted as to its importance and worth. ”

“ Under the influence of a craze, the moral character of a people suffers a reversion to a primitive type. In times of epidemic waves the moral standards of the crowd approach those of the savage. We observe the exhibition of primitive instincts, such as cruelty, revenge and blood-thirstiness, together with changeableness, fanaticism, self-sacrifice and enthusiastic devotion to a leader. All these moral traits were well illustrated in the Revolution crazes in France and in the persecution of witches in the sixteenth and seventeenth centuries. ”

“ He found that if we took two lights of equal apparent brightness, the one red and the other green, and then increased or diminished them in the same proportion, they would no longer appear equal. In other words, the geometrical axiom that halves or quarters of equal quantities are themselves equal, does not apply to the effect of light on the eye. If we diminish the two equal lights, we find that the green will look brighter than the red. If we increase them in the same proportion, the red will look brighter than the green. ”

“ The fact is, however, that the stars are very unequal in their actual brightness, and in consequence the apparent magnitude of a star gives us no clue to its distance. Among the nearer of the stars are some scarcely, if at all, visible to the naked eye, while among the brighter ones are several whose distances are immeasurably great. ”

“ Any war will furnish instructive material to the student of social psychology. In the late Spanish-American war, for instance, we all felt the war spirit which flowed in epidemic form across the country and engulfed it. The first motive of the war, the altruistic desire to free an oppressed people, was of the ideal glittering kind, well fitted to excite the emotions of the masses. ”

“ The psychology of crazes is clearly seen in certain of its aspects in the homicidal manias that have swept over communities or whole countries at frequent intervals in the world’s history. The homicidal impulse itself is one of the most primitive and basal of all impulses. The reason for this is apparent. The history of man has been a history of warfare and of struggle for existence. It has been man against man, tribe against tribe, nation against nation. Habits like these are not quickly unlearned, and reversion to them in times of social disturbance is not strange. ”

“ This is a piece of knowledge of the utmost importance to mankind, for we know that malarial disease in tropical countries—which, after all, in the future will be the most important parts of the world, seeing that they can produce more food than temperate countries and can therefore support a larger population—causes more deaths and more disposition to death by inducing cachectic states predisposing to other affections than all the other parasites affecting mankind put together. ”

“ The most perfect measure of the radiance of a star would therefore be the amount of heat which it conveys, because this expresses what is going on in the body better than the amount of visible light can do. ”

“ If you make a preparation of malarial blood from a patient by pricking the finger and spreading a little of the blood on a slide, fixing it immediately with heat or alcohol and staining it, you will never see any of these flagellated organisms. But if the slip be kept moist and in a warm temperature for half an hour and then stained, the flagellated bodies will be seen, proving that they develop only after the escape of the parasite from the human body. Such a fact is very interesting and obviously has some significance in connection with the life of the parasite. ”

“ At the same time, the State universities, directly supported by the people, are beginning to rival privately endowed institutions. It may be confidently asserted that no nation has ever so liberally supported higher education, and the wisdom of this liberality is now demonstrated, even from the most mercenary point of view, by the place the United States has taken in the world’s commerce. ”

“ As President Crafts remarked in a recent annual report, “We are less favored than many neighboring institutions in building space, but we have always followed the wise policy of keeping in the foremost rank and in some departments leading the way in supplying the best methods and apparatus for teaching and for making investigation. We have run in debt to buy them, and run282 still further in debt to build houses to hold them, but we have always had them when the head of a department told the government of the school that they were necessary to the most efficient teaching of his science.” ”

“ The apparent brightness of a star, as we see it from the earth, depends upon two causes—its intrinsic brilliancy or the quantity of light which it actually emits, and its distance from us. It follows that if all the stars were of equal intrinsic brightness we could determine their relative distances by measuring the respective amounts of light which we receive from them. ”

“ The American Association has this year made the experiment of selecting the end of June, immediately after the close of the college sessions, instead of a week in August. This has some advantages, but even at the beginning of the summer many men of science are either abroad or are engaged in scientific expeditions. The heat is apt to be excessive, interfering not only with the meetings, but also requiring some self-sacrifice on the part of scientific men when they leave their comfortable summer homes to travel through heat and dust to a hot and dusty city. ”

“ Although air is a mixture consisting mainly of four parts of nitrogen and one of oxygen, atmospheric nitrogen is generally inert at ordinary temperatures, and it is the oxygen of the air which is the more important factor in the growth of living things and in changes in lifeless matter. Water, a compound of oxygen and hydrogen, is present everywhere, either in the liquid form or as vapor in the air; even in the flame of the hottest fires there is water vapor in abundance, since water is one of the chief products of combustion of most forms of fuel. ”

“ UNIVERSITY OF IOWA. A well-known Washington newspaper correspondent, writing of the recent Congress of the Daughters of the American Revolution and its disorderly meetings, says: “It is the unanimous opinion of those who have attended the congress that, while the Daughters of the American Revolution, individually, are nearly all intellectual, refined and attractive women, collectively they are an uncontrollable mob.” Why is the social conduct of human beings different from their conduct as individuals? This is the problem of the new science of social psychology. ”

“ Neither is it difficult to understand the presence of this excessive emotion during mental epidemics or during any purely social movements, when we remember that war itself is the great original social movement, which even in this age always takes the form of a mental epidemic called the war spirit. The emotional effect of the mere physical congregation of a large number of men, the emotion increasing with the size of the assemblage, is known to all. ”

“ Most of the self-governing colonies have at their own cost erected fortresses, and they maintain a defensive force. Two of them have stationary ships of war. They are willing and eager, moreover, to aid the mother country when she is in difficulties. When England was embroiled in Egypt or danger threatened in India and South Africa, several of these colonies offered to send, and one actually sent, troops to engage in wars in which they were not directly concerned. The head and the extremities are sometimes at variance because their interests conflict. The heart of such an empire is one. ”

“ But it cannot judge definitely by comparison with relevant facts or by critically examining the logic of the deductions, for the general public lacks both knowledge of the relevant facts and training in logical criticism. That a man should invent a microscope which will enable one to see objects a million times as small as can be seen with the naked eye seems no more questionable to the general public than that a man should cause unfertilized eggs to develop. ”

“ Still, it is the case that the heads of two of our chief universities are men of great wealth, who have devoted not only their means, but also their services to the cause of education, and there are in our universities and other institutions many who hold their positions purely out of interest in their work, not as a means for their support. ”

“ Hence, observers have endeavored to give greater precision to it by the use of photometers,—instruments for measuring quantities of light. But even with this instrument the observer must depend upon an estimated equality of light as judged by the eye. The light from one star is increased or diminished in a known proportion until it appears equal to that of another star, which may be an artificial one produced by the flame of a candle. The proportion of increase or diminution shows the difference of magnitude between the two stars. ”

“ Even in our own times a striking example of the primitive character of the morality of a people under the influence of social excitement was seen in the battle-cry of our American sailors in the recent Spanish war, ‘Remember the Maine,’ the ethical motive being a precipitate impulse to seek revenge. ”

“ Thus, all the photometer can do is to give us the means of increasing or diminishing the light from one star, so that we can make it equal by estimation to that from some other star or source of light. ”

“ In America, the Rensselaer Polytechnic Institute, the pioneer in technical education, was founded in 1824, and was the only school devoted to applied science until the forties, when Joseph Sheffield and Abbot Lawrence established the schools which bear their names, in connection, respectively, with Yale and Harvard. With the development of railroads, which dates from the thirties, and of manufacturing, which began in this country but a few years earlier, urgent need was felt for schools which should fit younger men to grapple with the problems which the new industries offered. ”
