 ... basis of our present findings it is no longer enough to trace the appearing of the after-image solely to a differential fatigue in the retina. The fact is that as long as the eye is turned to the bright window-pane a more intensive blood-activity occurs in the portions of the eye's background met by the light than in those where the dark window-bar ...

This sense of the personal presence of an abiding Reality, fulfilling and transcending all our highest values, here in our space-time world of effort, may well be regarded as the differential mark of real spiritual experience, wherever found. It chimes well with the definition of Professor Pratt, who observes that the truly spiritual man, though he may not be any better morally than his non-religious neighbour, "has a confidence in the universe and an inner joy which ...

These groups are the main-drainage-system of modern life; they are the ordinary channels through which the business of the world has to pass, and its organised thought be directed. Take any one of these groups, and consider its differential character, its mode of apperception, its ethos, and you find it something deformed, twisted, strained in one direction, like a tree by the sea-shore. But take a few score of them, and imagine their qualities fused ...

... raceway. Its detachment from the axis forms a striking exception to the general construction of interlocking apparatus in this company's machines. Under the beak of this curious device is found an oblong recess, into which fits loosely a carrier or driver, rotating with a differential or variable motion. The space between the carrier and the sides of the recess is sufficient to permit the free passage of the thread in encircling the shuttle, and the differential movement ingeniously releases the contact between ...

The similar but less strongly marked arrangement of the stones in the ...

Their welcome of Mr. Thornberry was exactly what it ought to have been; respectful, even somewhat differential, but cordial and unaffected.

The critics who complain of the sickly separation of the beauty of nature from the thing to be done, must consider that our hunting of the picturesque is inseparable from our protest against false society. Man is fallen; nature is erect, and serves as a differential thermometer, detecting the presence or absence of the divine sentiment in man. By fault of our dulness and selfishness we are looking up to nature, but when we are convalescent, nature will look up to us. We see the foaming brook with compunction: if our own life flowed with ...

... The history of synthetic projective geometry has little to do with the work of the great philosopher Descartes, except in an indirect way. The method of algebraic analysis invented by him, and the differential and integral calculus which developed from it, attracted all the interest of the mathematical world for nearly two centuries after Desargues, and synthetic geometry received scant attention during the ...

... of proof would show "that the stature of a man or boy was identical, because the boy passes through every gradation on attaining the one stature from the other. No one could maintain such a position who grasped the doctrines of continuity and of the differential calculus." It seems to me that even without the help of the differential calculus, we can, with the help of logic and grammar, put a stop to this argument. Boy is the subject, stature looks like a subject, but is merely a predicate, and should have been treated as such by Mr. Darwin. If a boy arrives ...

... like is true of other fancy-bred animals—are rated and graded in aesthetic value somewhat in proportion to the degree of grotesqueness and instability of the particular fashion which the deformity takes in the given case. For the purpose in hand, this differential utility on the ground of grotesqueness and instability of structure is reducible to terms of a greater scarcity and consequent expense. The commercial value of canine monstrosities, such as the prevailing styles of pet dogs both for men's and women's use, rests on their high ...
