Page 107 - The general result of the foregoing paper seems to be that the fuller consideration of the physical properties of glacier ice leads to essentially the same conclusions as those to which Forbes was led forty years ago by the study of the larger phenomena of glacier motion — that is, that the motion is that of a slightly viscous mass partly sliding upon its bed, partly shearing upon itself under the influence of gravity.
Page 387 - Thus, although the production in large quantities of sterilised potable water is a matter of great difficulty, involving the continual renewal of filtering materials, there are numerous and simple methods of treatment which secure a large reduction in the number of organisms present in water.
Page 409 - Insolubility as ordinarily understood is a fiction, and separation by precipitants is nearly impossible. A new chemistry has to be slowly built up, taking for data uncertain and deceptive indications, marred by the interfering power of mass in withdrawing soluble salts from a solution, and by the solubility of nearly all precipitates in water or in ammoniacal salts, when present in traces only.
Page 153 - In not one of the many post-mortem examinations of typical acute cases have we found such a state. 4. The mucous membrane of the ileum, in typical, rapidly fatal cases, if examined soon after death, does not contain in any part any trace of a comma-bacillus or any other bacteria, not even in the superficial loosened epithelium. If the post-mortem examination be sufficiently delayed...
Page 410 - After six months' work I obtained the earth didymia in a state which most chemists would call absolutely pure, for it contained probably not more than one part of impurity in five hundred thousand parts of didymia. But this one part in half a million profoundly altered the character of didymia from a radiant matter spectroscopic point of view, and the persistence of this very minute quantity of interfering impurity entailed another six months' extra labour to eliminate these final "traces," and to...
Page xiv - In 1860 he was elected to the newly-founded Linacre Professorship of Anatomy and Physiology, which he held to the time of his death. He was elected a Fellow of the Royal Society in 1862, and a Fellow of Merton College, Oxford, in 1872.
Page 179 - ... 21. I have not up to the present seen my way to going further. It is certainly very extraordinary and paradoxical that light should suffer total or all but total reflection at a transparent stratum of the very same substance, merely differing in orientation^ in which the light had been travelling, and that, independently of its polarisation.
Page 277 - ... digestive tract. Existing under pressure, most of the blood at once emerges as a clear bright green or yellow liquid (when the derived pigments are present). It is received into a tubesection, with one end cemented to a glass slide, and when full a cover glass is placed upon the open end, becoming fixed by the drying of the blood. In most cases the blood so prepared will keep for months.
Page 416 - One important lesson taught by the many anomalies unearthed in these researches is that inferences drawn from spectrum analysis per se are liable to grave doubt, unless at every step the spectroscopist goes hand in hand with the chemist. Spectroscopy may give valuable indications, but chemistry must after all be the court of final appeal.
Page 153 - I have ascertained that the commabacilli of cholera show two distinct modes of division, one the known one of transverse division, and a second one of division in length. When growing in Agar-Agar jelly at the ordinary temperature of the room, after some days the bacilli swell up, owing to the appearance in their protoplasm of One or more vacuoles ; as these vacuoles increase, so the comma-bacilli become gradually changed, first into plano-convex, then into oblong bi-convex, and ultimately into circular...
