in I case the sinking was bilateral ; the right ovary contained 

 a cyst the size of a hen's egg, the left was normal ; 



in I case the sinking was bilateral ; the right ovary normal ; 

 the left contained a yellow body as large as a man's thimib and 

 to this was added the complication of a chronic purulent metritis ; 



in I case the sinking was bilateral and also there was 

 present cystic and fibrous degeneration of both ovaries and 

 prolapsus vagina ; 



in I case the sinking was bilateral ; the right ovary, of the size 

 of a hickory nut, was cystic and had undergone fibrous degenera- 

 tion ; the left contained a hypertrophied yellow body ; the os 

 uteri was open and chronic purulent endometritis present ; 



in 1 case the sinking was bilateral ; the right ovary contained 

 a cyst the size of a goose egg ; the left was normal. 



This tabulated summary indicates that sinking of the hips 

 generally indicates some affection of the sexual organs, especially 



of the ovaries, and that a good, fir m tensinn nf thp hrnp f^ ligg- 



ments of the pelvis constitutes excellent evidenc e of sexu al sound- 

 nessln the cow "because, between the character of the tension of 

 these sciatic ligaments and the specific sexual organs, there exists 

 a relationship quite analogous to that in man between the pos- 

 terior portion of the eye and cerebral disease. 



It further appears that the relaxation of the sciatic ligaments 

 does not alwavs in dicate bilateral. cvs tic.dfig.enerqtinr' of tVie^m^a- 

 ries, that in indivi dual cases it m ay occu r in the absence of cystic 

 degeneration and that the right ovary was found cystic twice as 

 frequently as the left. 



In general, we have determined that, when the relaxation of the 

 sciatic ligaments is unequal, the ovary on the side of the greatest 

 relaxation is the one which has, most probably, undergone cystic 

 degeneration. On the other hand, now and then, the broad 

 ligament is appreciably more relaxed on the side of the sound 

 ovary than upon that of the cystic gland and, in the bilateral 

 formation of the cysts in the periphery of the glands, the 

 greater sinking tends to occur on that side where the cyst or 

 cysts is the larger, firmer and older. Also, in unilateral sink- 

 ing of the sciatic ligaments, cystic degeneration may likewise be 

 unilateral and involve only that ovary on the side corresponding
