ABNORMALITIES. 39 



the Contents escaping into the abdominal cavity; or a ttocar 

 OF hollow needle with a long Tubber tube attached may be 

 used. A case of Degive's contained ten ounces. Dewar and 

 Anderson have , reported a "rase ^ in which a cystic testicle 

 (-intra-abdominal) removed from a two years old horse weighed 

 3 Ib^. 2 dz., and; when emptied only 5:oz. I dr. ' It measured 

 oyer iS.inches in diameter one way and, over: 16 inches the 

 other. • ■ '•, 



Dermoid cysts are hot uncommon. In the -oije here illus- 

 trated (Fig. 16) it was found that, when incised, five separate 

 cavities , were present, four of which contained hair. Someof 

 the latter was loose and some fixed. In colour the hairs-were 

 black, brown, and grey, and some of them measured seven 

 inches in length. In, the centre of the: whole mass there' was 

 an irregular bony plate, and the rest of the dermoid appeared 

 to be of fibrous tissue. 



In cases where the testicle is of enormous size, as an alternative 

 to .making" a large wound in the abdominal wall, Cadiot^ and 

 Degive suggest that the cord shall be pulled into the inguinal- 

 canal and cut through, a portion of it being removed, the enlarged 

 testicle thus being allowed to drop free into the abdominal cavity. 



The worm 'which sometimes finds its resting-place in the 

 surrounding envelopes of the testicle, and sometimes even in 

 the testicle itself, is the Strongylus Armatus? Mr J. B. Gress- 

 well has recorded a number of these parasites in a cavity in the 

 centre of an abnormal testicle; this organ being for the most 

 part indurated ,and weighing 4 lbs. 3 oz. 



In the human subject living acari {Histiogaster Sper- 

 maiicus^ ha.\e been found.* - In one particular instance the 

 patient was a doctor, and it was estimated, after careful 

 microscopical examination and calculation, that there were over
