All the German and American pathologists, who have accepted Cohnheim's teachings as the standard ones in the doctrine of inflammation, will of course ignore the novel views which completely upset a theory that held sway for nearly twenty-five years. Even their explanation of the silver images in inflamed cornese, that the isolated leucocytes adapt themselves by an intervening brown line of cement-substance, is proved to be erroneous. J. H. Mennen has shown that these brown lines are dotted, interrupted, owing to the presence of delicate intercommunications between the inflammatory corpuscles. This means that the inflamed cornea, although largely made up of indifferent or medullary corpuscles, remains a tissue nevertheless, and is able to re-enter its normal condition or become transformed into cicatricial tissue. It is only after the breaking of the interconnecting threads that the inflammatory corpuscles become isolated and now represent pus corpuscles. An abscess in the centre of the cornea is, therefore, the result of a disintegration of the tissue, and not an accumulation of leucocytes. Novel doctrines, deserving a rather acute power of observation will find approval in a slow way. It is, however, gratifying to learn that in the United States the new views, which are not the worse for having been dubbed "bioplasou theory " by my late friend Louis Elsberg, gain ground from year to year. Charles F. Cox, in an excellent presidential address, delivered before the New York Microscopical Society, January 3, 1890, expresses this progress in the following words: "I can well remember, as perhaps you also can, the disgusted incredulity with which this new doctrine was received,--an incredulity in which, I con...

Not illustrated. 1891 edition. Excerpt: ...distinction of parts. In the body of such a creature even the highest available powers of the microscope reveal nothing more than a fairly uniform network of material... the intervals of th& meshwork being filled, now with a fluid, now with a more solid substance or with a finer and more delicate network, and minute particles or granules of variable size... Analysis with various staining and other reagents leads to the conclusion that the substance of the network is of a different character from the substance filling up the meshes. Similar analysis shows that at times the bars or films of the network are not homogeneous, but composed of different kinds of stuffs..." From this the reader sees that the author contradicts himself. If there is no visibledistinction of parts as he at firsts declares, why does he then call attention to the differences in composition and even to the different parts composing the cell of the Amoeba? Precisely because he cannot get over the idea that the cell is made of different stuffs as he calls it, and that there are parts in it which not only differ in composition but in appearance; in a word, the cell is not a homogenous substance but is composed of parts, in other words, it possesses structure. But in bringing together what is known of the cell it is not my purpose to enter into controversy; I therefore leave the reader free to hold his own opinions. I will state the thesis of Carnoy in his own worda, and follow him as closely as possible in its exposition and demonstration. Prof Carnoy maintains that, " Cells are elementary organisms or individualities of organized beings," and that the cell is "a structured and living mass of protoplasm surrounded by a membrane and containing a...

This book was originally published prior to 1923, and represents a reproduction of an important historical work, maintaining the same format as the original work. While some publishers have opted to apply OCR (optical character recognition) technology to the process, we believe this leads to sub-optimal results (frequent typographical errors, strange characters and confusing formatting) and does not adequately preserve the historical character of the original artifact.

We appreciate your understanding of these occasional imperfections, and sincerely hope you enjoy seeing the book in a format as close as possible to that intended by the original publisher.
