140 PARASITES OF MAN 



and pathological departments of the Oxford Museum. Speci- 

 mens of large Ccenuri occurring in the soft parts of rabbits may 

 be seen in the Guy's Museum (presented by Mr Carpenter). 

 Similar characteristic specimens exist in the Oxford Collection, 

 labelled C. cuniculij obtained from the "masseter and infra- 

 spinatus " muscles of a rabbit. My private collection also 

 contains a recent addition of this remarkable hydatid, sent to 

 me by Mr Alston from Ayrshire. It is the only one I have 

 seen from Scotland. In the second half of this work these 

 Ccenuri will again come under notice. Three examples of the 

 slender-necked hydatid (from a monkey and two sheep respec- 

 tively) may be seen in the Guy's and University College Collec- 

 tions, and there are several in the museum of the Royal 

 Veterinary College. 



I cannot go out of my way to speak of other bladder worms, 

 except so far as to call attention to the heart of a bear preserved 

 in the museum at Guy's, the walls of which are crowded with 

 Cysticerci. That unique preparation ought to be carefully 

 examined and described. The Hunterian Museum contains two 

 magnificent specimens of hydatids affecting the bones of cattle. 

 In the one case a solitary vesicle occupies the shaft of the 

 humerus ; whilst in the other several " acephalocysts " have 

 taken up their residence within the cancellous structure of the 

 ilium. 



In the matter of human mortality from hydatids I have 

 already supplied statistical evidence of the unenviable distinction 

 which our Australian colonies exhibit, and in addition to the 

 facts brought forward I may add that Dr Lewellin has 

 mentioned to me a fatal case in which an hydatid occupied the 

 whole length of the vertebral canal. The patient was under 

 Dr Annand's care. There could be no doubt as to the genuine- 

 ness of the case, as the spinal cyst was tapped during life, 

 when echinococcus booklets were found. 



Through Dr Lewellin I am also indebted to Dr H. B. 

 Allen, pathologist at the Melbourne Hospital, for the particulars 

 of a case of hydatids of the cerebrum, which are given as 

 follows : 



" J. Q , aged 15, was admitted into the Melbourne Hos- 

 pital on the 13th November, 1877, suffering from partial left 

 hemiplegia. He rapidly became insensible and died next day. 

 His mother furnished the following history. 



" He had been woodcarting in the bush for a considerable
