358 DISEASES OF THE IiNTESTINES. 



peuded a contracted thread-like pointed part^ which is the 

 tail;, making up the remainder of its length. "When first 

 voided, the body appears black; the tail_, and at times the 

 liead too, transparent ; to the naked eye they have a sort of 

 pied or black and white aspect ; but through the microscope, 

 their bodies appear beautifully striped and spotted; their 

 head somewhat smaller than the body, out of which projects a 

 sort of proboscis or horn; while the eye and mouth bothof them 

 appear to be very small. No sooner are they taken out of 

 the dung than they vomit up their black contents, which 

 has the appearance of so much black ink ; and then their 

 heads and bodies, like their tails, become pellucid. In those 

 I examined, this ejectment seemed to be their last act of 

 life, for they never moved afterwards, but gradually shrunk 

 and dried up to almost nothing. Numbers of them were 

 voided by a young horse under the operation of physic, who 

 had given us no reason to believe he harboured worms of 

 any sort. Girard, fils, mentions a case of paralysis, in which, 

 after death, he accidentally discovered two strongyli within 

 the pharynx and oesophagus, and two others within the 

 stomach.^ In the case of a horse (H 20) six years old, who 

 had been admitted for the purpose of watching the effect of 

 the Butea (trondosa) given as directed by Mr. Western, very 

 many lumbricoid worms were brought away from him by 

 the operation of the physic with which the fourth dose of 

 the Butea seeds were combined, with a considerable number 

 of the strangylus worms as well, which latter had not been 

 observed before : he only being complained of for having the 

 long white or lumbricoid worms. 



The TAENIA, or tape worm^ used to be designated by the 

 French surgeons, ver solitaire, from a notion they entertained 

 that never more than one was found : of late, however, our 

 neighbours appear to have ample reason to change their 

 opinions ; since Chabert has reckoned 227 tape worms in a 

 dog; 91 in a horse; 19 in an ox; and 12 in a sheep. The 

 singularity of this worm, both in its appearance and struc- 

 ture, is too striking to be once seen without ever afterwards
