Excerpt from Studies in Cardiac PathologyThe opportunity of photographing specimens in the museums of five of the most important hospitals of Philadelphia having been afforded the author through the courtesy of the respective patholo gists of those institutions, * it has seemed worth While to reproduce the same in order to secure for these interesting examples of cardiac pathology a more enduring permanence and a more widespread field of usefulness. In order to enhance the value of the exhibit considerable data bearing on the patholdgy of cardiac lesions have been added. No attempt has been made to publish a com plete work on the pathology of the heart, the text being mainly in the form of an explanation and an elucidation of the illustrations, and but little space has been devoted to the microscopic tissue changes. The result is perhaps open to criticism as being too statistical in nature, and the same set of statistics can, as we know, only too often, be manipulated to prove opposing hypotheses. On the other hand, it cannot be denied that statistic compilation has done considerable for the advance of medical science, and there is much truth in Kant's dictum that the amount of pure science Which any given study contains is in direct proportion to the quantity of mathematics it includes.The author has endeavored to give due credit to all concerned.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
