^,« TREATMENT OF 



obtained from it great success, especially igainst 



the armed taenia. 



I have already remarked that in cases of old, 

 lar-e armed taeniae, the method of JVott/er was 

 insufficieut, and that on the contrary, with the 

 filings of tin, regularly administered, the desired 

 effect is promptly and certainly obtained.(190) 



% CLVI. To comprehend clearly the manner 

 in which tin produces these salutary effects, we 

 must reflect on an observation of Block, relative 

 to the lanciolate taeniae, which are found in great 

 numbers in the intestines of lean geese ; in small 

 numbers in fat seese.(191) In the latter, he sev- 

 eral times found some of these taeniae included in 

 the rectum and enveloped in the excrements, with 

 which they are commonly expelled. 



The reason why the lanciolate taeniae leave the 

 small intestines in fat geese, (the common abode ol 

 ^vorms,) is certainly not to be attributed to their 

 fat, but to the change of their nourishment. In 

 villages, geese commonly feed on the simple pas nre 

 of barren places, and consequently the lanciolate 

 taeniae accumulate in the small intestines, to be 

 nourished by the juice of the grass they eat 

 Whereas geese sold in the city are commo.ily ted 

 on barley and oats to fatten them. The goose di- 

 ^sts meal v*ry well, but the capsules of the gram, 

 :eparated only by the stomach, pass into the in es- 

 Uues. Hence it follows, that these small irreguUi 

 substances prick the worms and oblige them to de- 

 scend to the lower portion of the intestines, where,
