Elements of Vegetable Histology: For the Use of Students of Pharmacy, Preparatory, to the Study of Pharmacognosy; With 62 Illustrations (Classic Reprint)

Excerpt from Elements of Vegetable Histology: For the Use of Students of Pharmacy, Preparatory, to the Study of Pharmacognosy; With 62 IllustrationsThis little book is intended to serve as a guide for beginners in the study of plant tissues with the microscope, with supplemental instruction from the teacher.The greater portion deals with the tissues and their arrangement in the higher plants, but it was thought advisable to introduce a few lessons on the simplest plants, namely, some of those of the Thallophyte series, not only on account of their great importance in the life economy, but also to show the gradual increase in complexity of structure in passing from the extremely simple and minute plants of the Thallophyte series to the complicated highly organized members of the Phanerograms, thus giving the student a complete view of the structure and characteristics of the whole range of the vegetable kingdom.The knowledge of the tissues of the higher plants gained in this book, which may be designated as the Junior Course, will find practical application in the recognition of official vegetable drugs, the detection of adulterations, the study of ground drugs and their adulterations. This branch of study is called Pharmacognosy and is daily increasing in importance.The opening pages deal with a few physical principles and a description and explanation of the action of a compound microscope, its defects, the requirements of a good instrument, etc. The author is well aware that it is possible for one to work with a microscope without understanding its action, just as a man may know how to start and stop an engine without knowing anything of its mechanism and theory of action.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
