General Histology Of The Mammal PDF Download

Excerpt from A d104-Book of the Principles of Animal Histology A text-book of histology must have some very definite reason for appearing at the present time when so many good books bearing that title have appeared in the last few years and promise to continue to appear. These books, however, with practically no exceptions, have been intended for the medical school, and with this in view have been restricted to the histology of man, as a main theme, with more or less reference to other animals, principally the mammals. Such works have not filled the need of a text-book of general histology for the college course, a book that treats of the principles of the subject. They do not show what the animal cell is capable of as a builder of tissues which enable the organism to make use, more or less completely, of nearly all the known forces of physics and many of those of chemistry. This can be realized when we consider that they do not even mention such tissues as produce electricity, light, gases, and many other things. And again much is lost in the college course in histology by the fact that, of those tissues which are treated of in the medical histology, the complete significance is lost by not seeing their earlier representation and variation in the lower forms. This volume has been written to secure a work that covers the general field of histology and is not restricted in the main to human and mammalian forms. It is intended to be a work that teaches general principles and teaches histology as a pure science and for its own sake. It is believed that it will serve as a broad foundation for future studies of morphology and embryology as well as for the medical studies. As to method of treatment, it has seemed convenient to treat each part, with some exceptions, by writing a general discussion of the subject, and following this discussion with detailed laboratory descriptions of types of the tissue, abundantly illustrated with good pen and ink drawings. Such concrete examples have been selected from readily accessible materials in most cases, and the proper procedure for securing and preparing the materials has been indicated in small type at the end of each chapter in many cases. In the last part of the book a chapter on technique will be found, giving a short statement of principles and a guide for some concrete practice. In some chapters the seminar work is not separated from the statements of principles. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
