GRANULAR VENEREAL DISEASE AND ABORTION IN CATTLE. 45 



Case 3. — Aged, length of fetus 36 inches, about full term. Uterine seal softened. 

 Utero-chorionic space contained a tough, pale yellowish-red puslike mass of exudate 

 about the internal os. Further from the os internum, the utero-chorionic space con- 

 tained much uterine sand, bright orange-colored. While the exudate extended over 

 the entire utero-chorionic space, only that radiating from the internal os was typical 

 of contagious abortion. 



Case 4- — Aged, embryo 2\ inches. Uterine seal absent, either unformed or broken 

 down. Utero-chorionic space contains 10 to 12 ounces of thin, grayish-yellow purulent- 

 like exudate. Fetus apparently normal. 



Case 5. — Two-year-old, fetus 18 inches. Uterine seal softened and partly broken 

 down at internal os, but intact and normal elsewhere. Radiating from os uteri inter- 

 num in the utero-chorionic cavity for a distance of 4 inches is a tough, dirty grayish- 

 yellow exudate. 



Case 6. — Aged cow. Length of fetus 16 inches. Uterine seal intact. Abortion 

 exudate in utero-chorionic space radiating from internal os uteri 2 to 3 inches in the 

 nongravid and 12 to 15 inches in the gravid horn, mostly in flat, reddish-brown, tough, 

 gluey masses 1 inch long by one-eighth inch thick. In other places the exudate is a 

 dirty grayish yellow color, either semifluid or in tough, flat masses. The exudate 

 is deposited chiefly about the cotyledonal stalks, especially the more primitive ones 

 about the internal os. 



Case 7. — Aged. Length of fetus, estimated 6 to 9 inches. Uterine seal destroyed. 



Horns 3 inches in diameter by 10 inches long, hard, tense, with sclerotic walls one- 

 half inch. Uterine cavity contained 4 ounces of thin, brown, flocculent pus in 

 which were masses of bones apparently from a fetus 6 to 9 inches long. Apex of right 

 horn adherent to broad ligament. Abscess in uterine end of left oviduct containing 

 one-eighth ounce thick yellow pus. 



Case 8. — Aged. Twin pregnancy. Fetuses 9 inches, apparently long dead, mac- 

 erated, dirty gray, soft, odorless. 



Amniotic and allantoic fluids dirty gray, flocculent, opaque, odorless, chorion com- 

 pletely detached. Fetal membranes edematous, one-half inch thick. Utero- 

 chorionic cavity filled with fluid like that in amnion and allantois. 



Case 9. — Aged. Length of fetus, 30 inches. Uterine seal orange- colored and broken 

 down. Orange-yellow, gluey masses of exudate about the internal os 1 by one-eighth 

 inch in size. 



Case 10. — Four-year old. Length of fetus, 2 inches. 



The chorion of the left (nongravid) horn was detached from the right portion, necrotic, 

 dirty grayish in color, and surrounded by a dirty-grayish fluid exudate. A tough 

 yellowish exudate in the utero-chorionic space at internal os. 



Case 11. — Aged. Fetus full term, apparently alive at time of slaughter. Exterior 

 of uterus normal. Uterine seal apparently somewhat softened; otherwise normal. 



Utero-chorionic space filled with exudate throughout, except at one point in greater 

 curvature of the gravid horn, which appeared normal. The exudate varied in appear- 

 ance, dirty reddish-gray in color, in some places collected in irregular, flat, firm, gluey 

 masses 2 to 4 inches by one-eighth inch and at other points a semifluid, viscid mass. 



The exudate was thickest about the internal os uteri, and from that point radiated 

 out 18 inches to the apex of the nongravid horn, and 48 inches or more to the apex of 

 the gravid horn. The gluey masses were largely adherent about the cotyledonal 

 stalks. The chorion was markedly edematous, 1 to 2 inches thick. 



Case 12. — Aged. Full-term fetus. Uterine seal intact. Utero-chorionic space 

 filled with an abundant, tough, orange-brown, very gluey, sticky exudate, radiating 

 out from the internal os 4 inches in the nongravid horn and 12 inches into the gravid 

 horn, largely massed about cotyledonal stalks, but in places extending from cotyledon 

 to cotyledon. Exudate one-fiftieth to one-twentieth of an inch thick, and in masses 

 as much as 4 inches across.
