Excerpt from The Principles of Pharmacognosy: An Introduction to the Study of the Crude Substances of the Vegetable Kingdom In the morphological portion, which has experienced a complete transformation, we have endeavored to give a brief sketch of the most important phenomena, whereby the technical expressions in present use have received explana tion, especially those which occur in the deservedly widely distributed Syllabus of Eichler. Here, as in the anatomical portion, we have drawn the narrowest boundaries, since the present work does not pretend to be a complete text-book or manual. Nevertheless, some few sections which are of im portance to pharmacy have received relatively somewhat greater development and more precise adaptation, as for ex ample, that relating to the receptacles for secretions. A chap ter on the galls has also been newly inserted. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
