 ... double, consisting of two components which pass together to one pole. Examples of this are Syromaster, Phylloxera, Agalena. In a third class the sex-chromosome is accompanied by a fellow which is usually smaller, and the two separate at the differential division. The sizes of the two differ in different degrees, from cases as in many Coleoptera and Diptera in which the smaller chromosome is very minute, to those (Benacus, Mineus) in which it is almost as large as its ...

... difficulty in unweaving the maze, has its source in a misconception of the original machinery by which Christianity moved, and of the initial principle which constituted its differential power. In books, at least, I have observed one capital blunder upon the relations which Christianity bears to Paganism: and out of that one mistake, grows a liability to others, upon the possible ...

... falls exclusively within and never without the routine of Nature; and as universality is the characteristic of that routine, they do not hesitate, on behalf of science, to affirm that the Divine action is never addressed to specific or differential results, but always to universal or identical ones. In short, they logically refuse to the Divine power as exhibited in Nature all personal or moral quality, as inferring on the part of Deity any possible unequal or inequitable ...

... of a telescope. Sainte-Beuve, as he grew older, came to regard all experience as a single great book, in which to study for a few years ere we go hence; and it seemed all one to him whether you should read in Chapter xx., which is the differential calculus, or in Chapter xxxix., which is hearing the band play in the gardens. As a matter of fact, an intelligent person, looking out of his eyes and hearkening in his ears, with a smile on his face all the time, will get more true education than many ...

... observers at more than first magnitude on February 22, 1901. This "star," the paper tells us, when studied by its spectrum, is seen to be due to the impact of two swarms of meteors out in space—swarms moving in different directions "with a differential velocity of something like seven hundred miles a second." Every astronomer of to-day understands how such a record is read from the displacement of lines on the spectrum, as recorded on the photographic negative. But imagine Sir William Herschel, roused from a century's slumber, listening ...

... most indefinite of phrases, so far from obstructing his study, was in reality an aid to his thinking and a spur to excellence—not excellence over others, but over himself. There were moments, doubtless, long moments too, in which he forgot Homer and Cicero and differential calculus and chemistry, for "the bonnie lady-lassie,"—that was what he called her to himself; but it was only, on emerging from the reverie, to attack his work with fresh vigour. She was so young, so plainly girlish, that as yet there was no ...

... and when the equalising gasholder falls, and so reduces the pressure within the controlling chamber, the water in the latter rises and flows through the pipe to the generating tanks. The water supplied to the carbide is thus under the dual control of the controlling chamber and of the differential pressure within the generating tank. The four generators are coupled so that they come into action in succession automatically, and their order of operation is naturally reversed after each recharging. ...

In fact, nearly all tests, such as those used in studying differential psychology, are objective.

The examiner may observe the time occupied by the subject to complete ...

The revenue of the country was also, of course, injuriously effected by the post-office privileges already referred to as well as by the differential treatment of foreigners in regard to import duties. As was to be expected, any proposal for the abolition of extra-territorial rights and the revision of the regulations in regard to import duties met with a strenuous opposition from the foreign residents in Japan.

... better and fairer analysis than Hume's these features will persist. It, too, would be a product of selection, of a selection depending on its maker's preferences. As James showed, the distinction between 'dreams' and 'realities,' between 'things' and 'illusions,' results only from the differential values we attach to the parts of the flux according as they seem important or interesting to us or not. The volitional contribution is all-pervasive in our thinking. And once this volitional interference with 'pure ...

The subjects of these last are either general, comprehending both the others; or differential, distinguishing them. The general subject are either fundamental, or final: those of the fundamental kind are philosophy, human nature, the soul of man; of the final kind are love, beauty, good. The differential regard knowledge, as it stands related to practice; in which are considered two ...

... practically desert country and scanty water, is over 500 miles. To my mind it is in the Robat-Nushki portion of that distance, where travelling is difficult, and for troops almost impossible, that a railway is mostly needed. I have gone to much trouble, and risked boring the reader, to give all the differential altitudes upon the portion of the road between Robat and Nushki, and it will be seen that hardly anywhere does the track rise suddenly to more than 50 or 100 feet at most. The ground could easily be made solid enough to lay a line upon; tanks ...

Sir Isaac Newton (1642-1727) not only discovered the law of gravitation: other discoveries by him in mechanics and optics were of great moment in the progress of those sciences. Fluxions, or the differential calculus, was discovered independently by both Newton and Leibnitz. Euler, a Swiss mathematician of the highest ability (1707-1783), contributed essentially to the advancement of mechanics. Napier invented logarithms, to shorten mathematical calculations. Huygens, ...

... When the weight of the engine comes on these spokes, those nearest the ground are compressed and those, at the top are elongated a little. In order to avoid any of the driving strain passing through the springs, a strong arm is fixed on the differential wheel and attached to the rim as shown in Fig. 2, so that the springs have really no work to do beyond carrying the weight of the engine. Messrs. McLaren naturally felt a certain amount of diffidence in placing their invention before the public until they had thoroughly tested ...

This instinctive and deep-seated differential feeling we may regard as the outcome of complementary features, mental, moral, or physical, in the two persons concerned; and experience shows us that, in nine cases out of ten, it is a reciprocal affection, that is to say, in other words, an affection roused in unison by varying qualities ...

... in combination with either lead, copper, iron, or gold. As it resists oxidation and solution more strenuously than copper and iron, its tendency when in combination with them is to lag behind in migration. There is thus a differential enrichment of silver in the upper two zones, due to the reduction in specific gravity of the ore by the removal of associated metals. Silver does migrate somewhat, however, and as it precipitates more readily ...

If the truth must be told, the sage Leibnitz had a wisdom which now looks dreadfully like that of a wiseacre! In Mathematics even,—he did invent the Differential Calculus, but it is certain also he never could believe in Newton's System of the Universe, nor would read the PRINCIPIA at all. For the rest, he was in quarrel about Newton with the Royal Society here; ill seen, it is probable, ...

If the term rent is widened to include all differential unearned incomes, from land, from ability, from opportunity (i.e. special profits), interest includes all non-differential unearned incomes, and thus the State is to be endowed, not with rents alone, but with all unearned incomes.[52] It is true that ...
