THE SUPPRESSION OF TUBERCULOSIS TOGETHER WITH OBSERVATIONS CONCERNING PHTHISIOGENESIS IN MAN AND ANIMALS AND SUGGESTIONS CONCERNING THE HYGIENE OF COW STABLES AND THE PRODUCTION OF MILK FOR INFANT-FEEDING, WITH SPECIAL REFERENCE TO TUBERCULOSIS BY PROFESSOR E. VON BEHRING _University of Marburg_ _AUTHORIZED TRANSLATION_ BY CHARLES BOLDUAN, M.D. _FIRST EDITION_ FIRST THOUSAND NEW YORK JOHN WILEY & SONS LONDON: CHAPMAN & HALL, LIMITED 1904 Copyright, 1904, BY CHARLES BOLDUAN ROBERT DRUMMOND, PRINTER, NEW YORK TRANSLATOR’S PREFACE. The suppression of tuberculosis is of universal interest. A disease which is so wide-spread and which attacks the human race from so many points can be successfully combated only by the cooperation of many different agencies. It is therefore of great importance that the origin of tuberculosis be well understood not only by physicians, but by many outside the medical profession, such as dairy- and cattle-men, officers of health boards, sanitary engineers, etc. In order to present to the English reader in a concise and authentic form von Behring’s views on the origin and suppression of tuberculosis, the translator has made selections of von Behring’s articles from several different sources. The principal article is translated from a lecture delivered in Cassel, September 25, 1903. In reply to certain criticisms of a statement in this lecture, von Behring published an explanation in the _Deutsche medizinische Wochenschrift_, No. 6, 1904. This is reproduced, in part, in the Appendix. The two articles, “Observations on Phthisiogenesis” and “Suggestions concerning the Hygiene of Cow Stables” are taken from _Beiträge zur experimentellen Therapie_, No. 8, 1904. Each article, with the exception of the one just mentioned, is reproduced in full and without changes. In a subject of such controversial nature it is essential to reproduce faithfully the exact meaning of the original, and this has been done even though at times it may have led to awkwardness of expression. In a few cases where an exact equivalent for the German could not be found the translator has used the nearest English equivalent, followed by the German word in brackets.
