Page 178 - ARCHIVES OF MEDICINE: A Record of Practical Observations and Anatomical and Chemical Researches, connected with the Investigation and Treatment of Disease.
Page 177 - HOW TO WORK WITH THE MICROSCOPE. Fourth Edition, containing 400 Illustrations, many of them colored. Octavo. Price This work is a complete manual of microscopical manipulation, and contains a full description of many new processes of investigation, with directions for examining objects under the highest powers, and for taking photographs of microscopic objects.
Page 57 - If the inflammatory process still continues, and increases in severity, the vascular congestion becomes more marked, and the exudation is poured out from the blood more abundantly; the masses of bioplasm increase in number yet faster, and the exudation in consequence appears nearly opaque. The flocculi are of a yellowish colour, and look very like pieces of clotted cream which stick here and there to the peritoneum covering the intestines and the inner surface of the abdominal parietes. Not unfrequently...
Page 34 - When the germinal matter of the epithelial cells of certain mucous membranes, or that of other tissues of the body, or the germinal matter of the white blood-corpuscles, lives faster than in health, in consequence of being supplied with an undue proportion of nutrient material, it grows and multiplies to an enormous extent ; so that one mass may perhaps be the parent of five hundred, in the time which, in a perfectly healthy state, would be occupied in the production of two or three cells; And in...
Page 52 - ... cells or corpuscles which are so familiar to all who have studied morbid changes in the tissues as they occur in man and the higher animals. " Some of these active living particles may be so small as to be invisible by a power magnifying 5,000 diameters.
Page 159 - The minute contagious bioplast," he says, "is less than the T^oVinrth of an inch in diameter and often so very clear and structureless as to be scarcely distinguishable from the fluid in •which it is suspended."** Quite recently it has been shown that certain kinds of cells allow granules of protoplasm to wander from them under certain physiological conditions, and that these granules are not to be * Referred to by Dr.
Page 8 - ... potentially" cannot make it more correct. All we know is that such and such structures will result, but we know this from previous experience, not from reasoning. For the characters and composition of the living matter do not enable us to premise anything whatever concerning its formative properties. In the formation of man and the higher vertebrata the primary mass of bioplasm or living matter absorbs nutriment, and grows, and then divides and subdivides into numerous masses which are arranged...
Page 66 - ... certain favourable circumstances this grows and multiplies, producing disease. Particles of this virulent poison may be transferred from the infected organism to a healthy one, and contaminate it, even many years after its introduction into the first had taken place. Of syphilitic bioplasm there are different kinds, giving rise to different pathological affections belonging to the syphilitic class. Indeed, some facts render it probable that there are several different species or varieties of...
Page 62 - Chaveau showed that the active particles subsided after forty-eight hours, and that no effects were produced by inoculating the albuminous supernatant fluid, while the full effects were produced by vaccinating with the deposit. As would be supposed from the excessive minuteness of these bodies, they are not to be separated by ordinary filtration, but if the fluid containing them also contains a trace of coagulable fibrin diffused through it, this by contraction after coagulation would filter off...
Page 61 - I think they consist of a peculiar kind of living matter, the smallest particle of which, when supplied with its proper pabulum, will grow and multiply, giving rise to millions of little particles like itself, each having similar properties and powers
