and somewhat broadened at the other. The other form was longer and 

 at both ends thinner than at the middle portion. ^Microscopical ex- 

 amination revealed that this difference in shape and size was due to 

 different sexes. . . . The males are 4-5 mm., in average 4.5 mm. 

 long ; the breadth measures 0.02 mm. at the head, 0.05 mm. at the 

 middle and 0.13 mm. at the tail portion. In both sexes the anterior 

 end of the body is equally slender. The male has the posterior end 

 expanded in an umbrella-like fashion. . . . The fimales measure 

 5-6 mm., in average 5.5 mm. in length and 0.08 mm. across the head* 

 portion. The sexual opening is situate behind the middle of the body ; 

 there are two uteri, one running anteriorly and the other posteriorly, 

 both enclosing numerous eggs. The hind end of females is narrowed 

 and terminates in a sharp point. I have consulted with Prof. Ijima 

 about the worm and am told that it belongs to the genus Strongi/lus. 

 . . . Whether or not these parasitic worms had any intimate relation 

 with the disease of which the host died, it is now impossible to say. 

 . . . Even though they may not have had direct relation to that 

 disease, it would hardly be proper to assume of their immunity to 

 health." 



These are about all the vital points in Ogata's paper. I may add 

 that many more worms beyond the number assumed by Ogata were 

 undoubtedly left behind sticking to the stomach-wall and probably also 

 among the intestinal contents, which seem never to have been micro- 

 scopically examined. 8o that, the total number of the worms in 

 question in the entire aUmentary canal must have been a very con- 

 siderable one, unlike Looss' Egyptian cases. But as in the latter the 

 female worms were found, according to my memory, in much greater 

 abundance than the males. 



My own observations on the parasite were necessarily imperfect as 

 the specimens had lain dead several days in the putrefying stomach- 

 contents and were consequently by no means in a desirable state of 

 preservation. Nevertheless, what notes and sketches I could then take
