130 PARASITES OF MAN 



choicest specimens which I have examined is that contained 

 in the pathological museum of the Nottingham Hospital. 



When I first went over the collection of the Middlesex 

 Hospital Museum, I found it to contain fifty-four preparations 

 of entozoa, of which some fourteen only were true hydatids, 

 representing as many separate cases. There are now upwards 

 of a score of preparations of hydatids, several of the cases 

 having already had ample justice done to them by Dr Murchison 

 in his well-known memoir (' Edinb. Med. Journ./ Dec., 1865). 

 Amongst the most interesting preparations I would especially 

 call attention to two fine and genuine specimens from the 

 kidney, another very large example of an hydatid situated 

 between, the bladder and rectum, a simple acephalocyst removed 

 from the orbit (Mr Hulke's case), and the hydatid removed 

 from the axilla by the late Mr "Charles Moore. There is a jar 

 containing hundreds of hydatids that were taken from the 

 thoracic cavity of a dissecting-room subject, who was reported 

 to have died of phthisis ; and there is another preparation of an 

 hydatid of the heart, which also proved fatal, without there 

 having been the slightest suspicion entertained as to the true 

 nature of the disease. For this fine preparation the museum 

 stands indebted to Dr Moxon, of Guy's Hospital. Several of 

 the liver cases are particularly instructive; but amongst the 

 specimens presented by Mr Mitchell Henry is a small bottle full 

 of minute hydatid vesicles, all of which were removed from the 

 interior of the tibia. The history of this case has been lost ; 

 and, unfortunately, the bone from which the parasites were 

 taken does not appear to have been preserved. 



The museum connected with King's College contains at 

 least a dozen good specimens of liver hydatids, several of the 

 cases being of special interest from a pathological point of 

 view. There are two remarkably fine examples of hydatids 

 contributed by Dr Hooper, the parasites in one case affecting 

 the spleen, and in the other involving the ovary and uterus. 

 The spleen contained numerous encysted hydatids, whilst the 

 uterine organs exhibited " an immense collection " of the same 

 growths. In this place, also, I may refer to an hydatid-like 

 entozoon, taken from a cyst in the ovary of a female who had 

 been under the care of Dr Johnson (1860). It is, apparently, a 

 genuine example of the slender-necked hydatid (Cysticercus 

 tenuicolHs) and if so (as might be determined by dissection), 

 is, so far as I aware, the only specimen of the kind in existence
