STKONGYLUS SDBTILIS IN JAPAN. l57 



grey-coloured, not mixing bile. Eccliimosis and petechiae also in 

 subcutaneous tissues, in muscles, on retina, lungs, pericardium, dia- 

 phragm, mesentery, vaginal wall, &c. 



The fluid stomach-contents above mentioned were sent to Ogata in 

 Tokyo for microscopical examinations. It was in these that he 

 found the worms which form the real subject of this paper. They were 

 at that time not only shown to me but several specimens were kindly 

 given me for my own studies. I could declare at once that we had to 

 do with a new human parasite and that it represented a species of 

 Strongijlus, but whether an entirely new form or one already known 

 from some lower animals could not then be determined by me. There- 

 upon Ogata published an announcement of his discovery in a paper 

 written in Japanese and entitled " On a Certain Parasite " ( — -f^V ^ 

 ^g^), which appeared April 27th 1889 in the " Tokijo Medicinische 

 Wochenschrift " ('M'^^^Mt^>\ No. 578. As that paper is a very 

 short one I may here give a translation of the passages that are of in- 

 terest to helminthologists. 



" On slide-preparations," writes he, " that I made of the turbid, 

 chocolate-coloured stomach-contents, I have once discovered a parasitic 

 worm, besides often meeting with free eggs of some parasite. Hereupon 

 I poured out one-half (about 10 grammes) of the stomach-contents into 

 a glass dish and by means of a lancet-shaped needle, the sharp end of 

 which was dipped into the fluid and uplifted after a stirring motion, I 

 could pick up several more worms that came up attached to the blade. 

 Washed in distilled water, these looked white, not unlike a piece of 

 slightly bent cotton-fibre of about the size of the hair that grows upon 

 the back of one's hand. In this way I succeeded in obtaining over one 

 hundred specimens, so that in the total volume of the fluid at my 

 disposal (about 200 grauumes) there must have been present undoubtedly 

 over two hundred of the worms. After washing they were transferred 

 into a camphorated 0.57o solution of table-salt (which fluid prevents putre- 

 factioji and preserves shape for a long time). I could then distinguish two 

 forms among my specimens. One of them was shorter, thin at one end
