we have dealt rather fully with the historical and patho- 

 logical sides of the subject, whilst in the present communi- 

 cation we propose to deal with the zoological characters 

 of the worm and the possible means of its transmission. 



For the purpose of examining the anatomy of the worm 

 in detail, the dense outer fibrous capsule was removed and 

 the complete mass enclosed in its innermost thin capsule 

 was shelled out. This inner capsule was then opened by 

 means of small incisions, and in some cases its contents 

 were carefully teased out at once, whilst in other instances 

 the aids of early putrefactive processes and of pancreatic 

 digestion were used to loosen the connective tissue sur- 

 rounding the coils of the worm and enable larger portions 

 of the parasite to be extracted undamaged. 



An examination of all the fragments removed in this way 

 from individual worm-nests revealed the fact that in many 

 instances apparently only one female worm was present in 

 each, that more rarely both a male and a female were 

 present together, and that sometimes portions of at least 

 two female worms were found. It must be borne in mind, 

 however, that occasionally we entirely failed to extract 

 either end of an individual (owing to the extreme difficulty 

 in removing from its fibrous bed every portion of the worm) 

 from which it will be obvious that the instances in which 

 evidence of the presence of a single worm was alone 

 obtained may really be less numerous than at first sight 

 they appeared to be. 



A brief description 2 of the worm has already appeared 

 but we deem it advisable to give a corrected and more 

 detailed account of it here. 



General Description. -The body is greatly elongated and 

 closely coiled. As we have stated above, it is very difficult
