2o8 Veterijiary Obstetrics 



thousands of cases of cystic ovaries, we find the recent and 

 easily ruptiirable ones chiefly in heifers and in cows which have 

 recently calved and indeed with equal certainty whether the 

 duration of pregnancy has been normal or not. The same is true 

 of nymphomaniac cows which have only recently become affected, 

 and of cases previously treated, in which the cysts have recently 

 recurred. 



By mere accident apparently, in certain herds in which the 

 cows and heifers run at pasture the entire summer and where 

 thej^ receive very little artificial food, the cysts are generally thin 

 walled and easily ruptured. 



If the peripheral cysts be of long standing and possess a thick, 

 tough capsule, earnest warning need be given, before the rup- 

 ture of the cysts per rectum is undertaken, against the accom- 

 panying dangers of severe maiming or tearing of certain, or of 

 all the tissues of the rectal walls. 



It makes a bad showing if — in cases where the operation has 

 been very difficult, as for example, where the patient is very 

 resistent, shows great uneasiness and strains violently, or 

 great sensibility in the ovaries which have already been sub- 

 jected to the crushing of cysts several times, or difficulty in locat- 

 ing and grasping them, etc., — the operator withdraws from 

 the rectum a bloody hand, since these unfavorable appearances 

 do not tend to increase the esteem in which the operation is held, 

 nor the standing of the operator. 



In peripheral cysts of varying ages, a cyst in one ovary may be 

 easily crushed while, in the other gland, one of equal size will 

 be very difficult or impossible of rupture. In cases of two or 

 more cysts in one ovary, first one cyst and then the other is felt 

 to rupture, after which there is recognizable a minute fragment 

 of the ovary, which, however, amply suffices for inducing the 

 occurrence of normal estrum, although the remnant consists 

 merely of an empty, collapsed capsule; a small, empty, flat bag. 

 If, in addition to one or two cysts, a corpus luteum is found, 

 the latter usually becomes ruptured or pressed out first and then 

 the cysts often burst .spontaneously ; however, it sometimes 

 occurs, as shown by our collection, that the cj^sts rupture while 

 a small corpus luteum remains intact in the ovary, and for its 

 dislodgement a still greater pressure is necessary.
