Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Excerpt from Manual of Vital Function, Testing Methods and Their Interpretation There should always be some valid reason for writing a new book, especially a medical book. My reason for writing, or perhaps to express it more accurately, for compiling this work, is, that the information that it contains is scattered quite broadly thro a wide and extensive medical literature, that may not be readily accessible to all, and which has never, so far as I know, been collected together in book form. Inasmuch as every progressive physician and surgeon at the present day is making more or less frequent use of the different functional tests, to determine the efficiency of vital organs, it occurred to me that to collect them all in one volume, together with the necessary data whereby they might be intelligibly interpreted, might prove to be useful, particularly to the busy practitioner. The following work, which is an effort to carry out that idea, includes only the tests for so called vital functions, namely those applied to the liver, kidneys, heart, pancreas, and ductless glands. To go beyond this and take up functional tests of all the organs, such as the eye, ear, nervous system, etc., would be to exceed the legitimate field of true function testing and to encroach upon the well-trodden fields of general semiology and diagnosis. I hope the book may prove to be useful and convenient to all who are interested in this fascinating and ever-developing field of clinical pathology.
