The cultivation of amebas,1 while a subject of the greatest importance, has never excited a very general interest, especially in America; and, although there is an extended literature on the subject, it is scattered over a long period of time and unfortunately some of the earlier writings deal with work not performed with proper care. This early and unsatisfactory work accounts partly for the small amount of attention which the more careful articles of recent times have received, and materially adds to the responsibility of those who now take up the subject. Some of the confusion and doubt which exist in regard to cultivation and etiology is also due to the fact that a number of those who have grown amebas have, although insufficient data were at hand, devoted much time to a discussion of the biology and classification of the parasites. The controversy relative to the etiologic significance of these parasites in human disease has been active almost since the time of the very important observations of Loseh, and, to judge from much of the recent literature, is still far from being decided. Any attempts at the solution of these problems must take this doubt into consideration, and every detail of the subject must therefore be made clear. 1The authors have followed Dorlnnd's Dictionary in spelling. In this first paper we have purposely avoided a detailed discussion of the life cycle, the classification, and other strictly biologic questions regarding amebas, but instead have taken up their cultivation from various sources, including thte dysenteric intestine, and have proved their etiologic role by animal experiment...
