172 DROPSY OF THE SKIN. 



-Encysted Dropsy. — An accumulation either of serum, or of 

 a fatty or gelatinous matter, within a particular sac, is thus called. 

 The dropsy of the ovaria is by much the most frequent of this 

 kind, and, to a certain extent, is very common in bitches ; but it is 

 in these general cases more an accumulation of fat than serosity. 

 I have, however, seen instances of true ovarial dropsy of the 

 hydatid kind, which all terminated fatally, although they proved 

 very slow in their progress : they are to be detected by the swelling 

 being less universally diffused, and having obscure undulation. 

 The tumours may also be often traced to have commenced on one 

 side only ; sometimes it continues to occupy more of one side than 

 the other : the enlargement, probably, first appeared in the loins, 

 and did not extend downwards until it gravitated there by its 

 weight. The treatment of these cases must be the same with that 

 of ascites ; but I never saw but one which did terminate favoura- 

 bly, and in that I discharged the fluid contents by a trochar 

 effectually: in others, this mode failed, and even hastened the 

 death. 



Hydatids, independent of the ovaries, likewise now and then 

 form a species of dropsy in other parts. I have seen them in the 

 liver, the lungs, the spleen, and the brain. 



Dropsy of the eye-hall is sometimes seen either idiopathic or 

 traumatic. — ^ee Diseases of the Eyes ^

CANINE SCIRRHUS AND CANCER. 



SciRRHUS in the human subject is considered as the primary 

 stage of cancer ; but dogs, though very subject to tumefactions 

 which present much of the character of human scirrhus, and which 

 degenerate into obstinate and increasing ulceration, yet do not 

 often present an equal likeness of the human cancer. The canine 

 scirrhus, likewise, is not wholly like that of our own ; for, instead
