whitish, hard kernels not larger 

 than a pinhead. These kernels, if 

 compressed between two slide 

 glasses and examined with a mag- 

 nifying glass, show an oval or 

 roundish worm-like body with a 

 short and rather broad neck (in 

 its contracted state) and a mi- 

 nute head. If put under micro- 

 scopic examination, it is at once 

 apparent that these bodies are 

 some species of the larval state of 



appearance of these minute taenia 

 bodies plainly. In general these 

 echinococci of rabbit correspond 

 to the echinoccoecus parasite of 

 man, only that in man, while it 

 is found in nearly all organs, but 

 especially in the liver, it is a para- 

 site that, as stated, nearly exclu- 

 sively infests the muscular sys- 

 tem of the rabbit — similar to the 

 trichina spiralis of man, and some 

 species of cysticerci — only that

the taenia echinococcus — showing 

 the peculiar segmented apartment 

 across the body and neck of the 

 worm, and the head-part shows 

 a number of round sucking-cups 

 generally four or six, and a num- 

 ber of delicate curved booklets. 

 Some of the micro-photographs 

 herewith submitted and prepared 

 from a rabbit killed only a few 

 days agOj show the histological 



the latter in the rabbit, like the 

 echinococcus of man, more often 

 invade the liver, kidneys, dia- 

 phragm, lungs, pleura, intestines, 

 the bulbus, pelvic organs (espec- 

 ially the subreetal tissues),, lym- 

 phatics and subcutaneous cellular 

 tissue, etc. The echinococcus 

 tapeworm in man is described as 

 a very small taenia, with only 

 four or five joints.
