ing essentially of oil of tar, oil of peppermint and other volatile oils was in- 

 jected into the uterus. 



January 27th, no improvement, same treatment given as on January 25th. 



January 29th, no improvement, same treatment given as on January 27th. 



January 31st no improvement, irrigated uterus with weak solution of coal 

 tar product followed by an injection of three ounces of 5 per cent solution 

 of formalin. 



February 7th some improvement noted. There is'some purulent exudate 

 in the uterus but not so much as at last treatment. Irrigated uterus with 

 warm physiological salt solution and injected three ounces of 5 per cent solu- 

 tion of formalin into the uterus. Animal manifested severe uterine pain 

 immediately following this treatment. 



February 14th still considerable pus in the uterus. Irrigated uterus with 

 salt solution and injected two ounces of undiluted LugoFs solution of iodine 

 into the uterus. 



February 19th, considerable improvement noted, very little pus found in 

 the uterus. Uterus irrigated with salt solution to which was added about 

 0.5 per cent of a coal tar product. 



February 25th, marked improvement, no pus in the uterus but right horn 

 slightly enlarged. Wall thickened but no fluctuation. Cervical secretions 

 excessive, slightly adhesive but practically clear. The cow was given vaginal 

 douche of 1 per cent sodium bicarbonate and three-fourths of 1 per cent 

 sodium-chloride solution. No further treatment was given and the animal 

 was slaughtered for beef May 12, 1919. 



Macroscopic Examination: External os slightly dilated but folds not 

 apparently hypertrophied. Cervical canal ten cm. long, contains consid- 

 erable clear mucus as in heat. Body of uterus three cm. long. Mucosa of 

 grayish drab color apparently uniform. There is what appears to be a radiat- 

 ing cicatrix about one cm. in length by six mm. wide just anterior to the 

 internal os. The right horn is about one-half larger than left horn and ap- 

 pears edematous. On section mucosa is of a grayish drab color fairly uniform 

 though apparently more vascular in the dorsal than in the ventral part. 

 Mucosa is apparently thickened and edematous. There is present some clear 

 mucus. The cotyledons are apparently normal in number, vary in size from 

 three to six mm. in diameter and the center of the cotyledon is more vascular 

 than the periphery, the latter having a grayish yellow appearance. On close 

 examination the gland mucosa is not uniform but there are numerous inter- 

 crossing and irregular small grayish lines which may represent the inter- 

 glandular tissue. The left horn is very slightly if any enlarged and on section 

 the mucous membrane appears edematous though the thickening is not so 

 great as it is in the right horn. It has the same general appearance. Left 

 oviduct is normal, left ovary is oval, four and one-half cm. in its greatest 

 diameter and contains a cyst-like structure about one cm. in diameter and 

 numerous small immature folicles. There has apparently been some con- 

 traction of the ovarian ligament between the anterior end of the right horn 

 and ovary. The.hgament is thickened at this point and the right oviduct 

 is not observable except on close examination. The oviduct does not appear 

 enlarged. Right ovary is about four cm. in length and contains a corpus 

 luteum about one cm. in diameter. 



Histological Examination : The mucosa of the cervix is covered in its pos- 

 terior part by a stratified epithehum fifty microns high.. Anteriorly, the 

 epithelium is simple ajid averages about sixteen microns in height. In' places
