Tinlins & Co., Ltd., Imp. 27 MEASUREMENTS OF AND OBSERVA-TIONS UPON THE CYSTS OFENTAMOEBA HISTOLYTICA ANDOF ENTAMOEBA COLI BY A. MALINS SMITH, M.A. (Cantab.) From the Liverpool School of Tropical Medicine (^Received for publication 26 March, 1918) From April 22nd, 1917, until March 4th, 1918, the writermeasured the dimensions of 2,833 cysts of two of the intestinalentamoebae of man, E. histolytica and E. coli. The results of thesemeasurements are given in the present paper. At the time eachmeasurement was made the nuclei of the cyst were counted andtheir number recorded. A note was also made of the presence orabsence of chromatoid bodies and vacuoles. The main results ofthese observations are recorded here also. METHODS The majority of the stools from which the cysts to be measuredwere taken were those of convalescent dysenteries, and were sent tothe laboratory for the usual routine examination for dysentery.Cysts were also measured from a small number of carrier
