. Physical diagnosis . Fig. 2ir.—a, Head of Taenia saginata, much magnified; b, uterine canal of same,twenty branches on each side. About amined at once with a high-power dry lens. The organism is rec-ognized as an amoeba by the presence of distinct amoeboid dead it assumes a round shape, but one should not attempt apositive diagnosis until live amoeboid parasites are present. Apparently there is a harmless variety of amoeba coli to be obtained from the stools ofmany normal persons by purgation. This is distinguished from the amoeba histolyticaby the following criteria (Vedder).

This is distinguished from the amoeba histolyticaby the following criteria (Vedder). The dysenteric or tissue-destroying amoeba is larger,more actively motile, has an easily distinguished refractive ectoplasm which can also bemade out in the pseudopods which are themselves relatively large and easily seen. Especially characteristic of the amoeba histolytica is the presence of numerous vacuolesand usually of ingested red corpuscles which hide the nucleus. 382 PHYSICAL DIAGNOSIS The other parasites ar
