Oswaldo Cruz, 42, (1), Studies on the making and the development of proglottids of and Dipylidium caninum By Ryotaro Hiwada From the Bacteriological Institude medical college, University Okayama (Director: Prof, Dr. M. Suzuki ) For all various studies, the making and the development. of proglottids has not been known as Braun's words gdie naheren Vorgange bei der Bildung der Proglottiden sind uns bisher noch ganz unbekannt." On cestode, we have nothing for the fundamental knowledge to the making and develop ment of all gewebe and organe, namely, cuticle, muscle, nerve, excretoryorgane and genitalor gan. So I have observed the making and the development of proglottids of typical cestodes, and Ditpylidium caninum since march 1941 under the kindly direction of prof. Dr. M. Suzuki. My main points of the results of the observation are as follows. 1. The fundamental mechanisms of the making and development of proglottids between and Dipylidium caninum are completely same.

22 2. The making and development of proglottids of and Dipylidium ca ninum is held out mainly at scorexbase and more at cervixand at first external proglottids were made, then proper proglottids developed from divisions mechanisms in those external proglotti ds. 3. Cuticle were made from circular cells in subcuticle celllayers, muscle were made from circular cells insiside subcuticle, fibrous tissue from cells in Parenchym. 4. Only genitalorgane wer made and developed newly in proglottids from circular cells in parenchym and subcuticle cells, but these Begining were looked erly in external proglot tids and there were any difference between cells which make up cuticle and muscle of geni talorgane and cells which transform into keimcells at those form and dyeing. 5) And again I could not find any difference at form and dyeing between cells which made up cuticle, muscle, nerve fibres and cells which tranoformed into Hoden and keimstock. 6) In younger proglottids there were many those circulas cells in all tissues, but in older proglottids I could not observed these cells a few. 7) The nucleus of these cells are 2,800-7,600, at, 2,600-4,500, at Dipylidium caninum in length at diameter, and coloured up violet with Hamatoxylin.
