Diagnostic methods, chemical, bacteriological and microscopical : a text-book for students and practitioners . described a unicellular ameboid body which resembles veryclosely a eucocyte when stained, but, while motile, differs in refractility andstaining quality.

It should be noted here that these organisms may not be numerousso that many shdes may have to be examined. Nothing should be called anameba unless it shows true ameboid movement.

Such formations may, also,be found in cases of liver abscess perforating into the lung. Any one of theabove formations is characteristic of this condition. The parasite will be dis-cussed fully in ihe section on Feces, to which the reader is referred. The sputum in such cases is usually purulent or mucopurulent and maybe tinged with blood.
