fist, round, smooth and fluctuating. The cow showed normal 

 estrum 14 days after the operation. 



6. Supplementary to the foregoing, we shall here submit, 

 through the courtesy of Professor Dr. Gillebeau, the appended 

 postmortem findings relative to cystic degeneration of the ovaries: 



1. A cow which had been handled by us for a long time was castrated on 

 December 3, 1903. The right ovary weighed 20 grammes and contained in 

 its center 2 follicles the size of peas ; the one had the ordinary contents, the 

 other was filled with clotted blood, evidently the result of preceding severe 

 crushing. Otherwise, the ovary was in a state of advanced fibrous degener- 

 ation. The walls surrounding the follicles were 7 mm. thick. 



The left ovary, weighing 30 gr., was as large as a ^hen's egg, 4 cm. in 

 diameter and contained 6 peripheral Graafian follicles, as much as 5 mm. in 

 diameter, and one central Graafian follicle, i cm. in diameter, with yellow 

 walls and contents consisting of a yellowish-red fluid serum and blood 

 clots, which was likewise referable to the previous crushing of the organ. 

 Otherwise, this ovary also showed extensive fibrous degeneration. 



Anatomo-pathologic diagnosis : sclerosis of the right ovary and cysto- 

 fibrous degeneration of the left. 



2. A 6-year-old cow. Six months previously, ovarial cysts had been 

 crushed for the first time ; later, they recurred. The patient suffered also 

 from vaginal prolapse. Slaughtered on the 21st of December, 1905. The 

 vagina was decidedly wide, the mucosa covered with much tenacious mucus. 

 The habitually prolapsed portion was intensely hyperaemic, the lips of the 

 OS uteri swollen, the cervical canal penetrable for one finger. Weight of 

 uterus 900 grammes, as against a normal weight of 600 to 700 grammes. 

 The exaggerated weight is referable to the hypermaemia of the cervix. 



Uterine cavity normal. Left ovary somewhat enlarged, tissue dense with 

 one follicle of the size of a pea and 2 yellow bodies. The right ovary con- 

 sists of a cyst the size of a hen's egg, with clear contents, a moderately 

 large yellow body and a vestige of normal ovarian parenchyma. 



Diagnosis : Chronic colpitis and cystic degeneration of right ovary. 



3. A 2 ^ year heifer, which had not been pregnant, was first handled on 

 May 8, 1895, because of a cyst in the left ovary of the size of a hen's egg. 

 On the 28th of the same month there was recurrence of a cy»t in the same 

 ovary, and 4 weeks later a recurrence of cysts in both glands. She was 

 slaughtered August loth, 1895. 



Anatomo-pathologic findings : 



The dorsal vaginal arch is dispropoj tionately deep, so that the os uteri 

 externum is not directly toward the vulvar opening but downwards against 

 the vaginal floor. Above the os externum there lay a broad lip, which, in 

 the usual condition, scarcely covered the os, but when hyperaemic certainly 

 must have covered it completely. Uterus and oviducts were normal. 



The right ovary weighed no grammes. Its length was 3.5 cm., breadth 

 2.5 cm. and thickness 1.5 cm. At various points on the surface |there ap- 

 peared yellow bodies 3-7 mm. broad. Through the dense fibrous tissue of
