Note 1 — EDITOR’S PREFACE.

In the Note prefixed by Dr. Hays to the “Code of Ethics of the American Medical Association,” he writes as follows:—“On examining a great number of Codes of Ethics adopted by different societies in the United States, it was found that they were all based on that by Dr. Percival, and that the phrases of this writer were preserved to a considerable extent in all of them. Believing that language so often examined and adopted, must possess the greatest of merits for such a document as the present, clearness and precision, and having no ambition for the honors of authorship, the Committee which prepared this Code have followed a similar course, and have carefully preserved the words of Percival, whenever they convey the precepts it is wished to inculcate.”
