Stained filma saowe the red cells to b" practically normal ; there was verv sli.:ht irregularity in the size of the corp 18clei, but there were no definite microcytes or msterocytes No nucleated red cells w-re fonnd. The differential leucocyte count per cent. was: Small lymphocates, 25'0; large lymphocvtes, 13.5: hyaline', 9'0; polvmorphonacl -ars, 51.0; e.sinophiles, 1'0; bas)philes, 0'5. Thus, there was practically no anæmia and no eusinophilia. As to history, the patient had never been out of Ireland, and lived in the County Leitrim near t.e river Sha.,non. Six years ago she tt -d been in an infirmary, where she was treated for tape-worm. She bee;a.'1 to corn "!airl again about tw years ago, with symptoms of g-istric ulcer. She had occasionally etteri the following fish, fried : Pike, perch, trout. . She did not remember having eaten any badly-c ooked fish. She did not kn'w any other perion who suffered from tape-worm" in the district. The patient came from a town 15 miles uo the river, from the place in which the other case, a m-in, resided. The ab-enceof anv definite anæm a in these tw cases was of interest. Unfortunately, the head of the worm nad not been secure t.

In regard to the preparation of segment-exhibits, for comparison between B. latiis and Tænia saginata, these can be very readily mounted in gelatin-formalin.
