BY HERBERT MAYO, SURGEON, AND LECTURER ON ANATOMY. LONDON: PUBLISHED BY BURGESS AND HILL, GREAT-WINDMILL-STREET. ADVERTISEMENT. THE following pages contain the heads of the Physiological Lectures delivered by the Author in the School of Great-Windmill-Street, together with a short account of the structure of the principal organs in the human body. To be practically useful, a treatise on Physiology should present or recall to the mind of the reader a clear conception of the parts, the uses of which it describes: at the same time it must be short; and thus its scope is limited to a concise explanation of the more important functions of the body. A treatise fitting the magnitude of the subject would not suit the present thriving condition of Medical Science. So rapid is the progress of Physiology, that the first part of such a work would begin to be obsolete before the publication of the last; not to mention, that it would be too voluminous and expensive for students, and would be neglected by men advanced |
