الصفحة 247 - Stubs's steel wire gauge to work well for the air and fluid orifices respectively ; and it may be added that metal points reduced to sharp edges are preferable to glass, which, by its non-conducting properties, allows the orifices to become obstructed by frozen aqueous vapour.
الصفحة 247 - ... its free delivery; 15° below zero is easily produced by this apparatus. The bottle, when not in use, should be kept tightly corked, a precaution by no means superfluous, as the liquid readily loses its more volatile parts by evaporation, leaving a denser and consequently less efficient residue. In this, and in several more expensive forms of apparatus in metal, both with...
الصفحة 261 - J-inch magnetoelectric machine, having on its cylinder six permanent magnets, was transmitted through the coils of the electro-magnet of the 5-inch electro-magnetic machine, and when the direct current from the latter was simultaneously, and in like manner, transmitted through the coils of...
الصفحة 247 - ... of a means of producing dynamic electricity in quantities unattainable by any apparatus hitherto constructed. He has found that an indefinitely small amount of magnetism, or of dynamic electricity, is capable of inducing an indefinitely large amount of magnetism, — and again, that an indefinitely small amount of dynamic electricity, or of magnetism, is capable of evolving an indefinitely large amount of dynamic electricity.
الصفحة 42 - The rosolic acid obtained from rosaniline is free, or almost free, from leuco-rosolic acid. Be this, however, as it may, there can be no doubt that rosaniline and carbolic acid give essentially the same product...
الصفحة 50 - The former is indicative of disease, and the latter is a sign that the animal has died from natural causes. Good meat has also a marbled appearance from the ramifications of little veins of intercellular fat ; and the fat, especially of the internal organs, is hard and suety, and is never wet ; whereas that of diseased meat is soft and watery, often like jelly or sodden parchment. Again, the touch or feel of healthy meat is firm and elastic, and it hardly moistens the fingers ; whereas that of diseased...
الصفحة 201 - ... liver, kidney, urine, bile, blood, brain, and muscles. The nerves and aqueous humour showed much less increase, and the lenses showed the least increase of all the textures. In six hours the amount of fluorescence was rather less than in three hours. In twenty-four hours it was considerably less than half as much as in three hours. In forty-eight hours, except in the liver and blood, there was but little more fluorescent substance in the textures than naturally exists there. And in seventy-two...
