Exploring per rectum, the operator finds the uterus verygreatly distended, lying inert, and containing from one to severalgallons of liquid, which fluctuates upon palpation. There are few affections which may be confounded in referenceto diagnosis with chronic metritis. Occasionally we meet with asimilar discharge from the vulva in case of a very large calculusin the bladder, accompanied by purulent cystitis. Other forms ofpurulent cystitis maj cause like symptoms, as may also a malig-nant tumor of the bladder when breaking down. Chronic vag-initis mav also be mistaken for this affection, until manual ex-. FlG. 141. PV0MHTR.\ IN MaRE. O, O, Ovaries. UC, Uterine cornu. U, , Indurated cervix uteri. V, Vagina. ploration is made. In Case 3 we record below an instance of ter-atologic development of the uterus, which induced symptoms ofchronic metritis. The changes observed in the uterus consist chiefly of a thick-ened and sclerotic condition of the cervix uteri, with extreme 888 Veteri7iary Obstetrics narrowing of the os. The mucous membrane completely losesits ordinary character ; ulcerating patches appear ; and, as shownin Fig. 141, the cornua become displaced from their normal po-sition at right angles to the uterine body, and push forwardsomewhat in the direction assumed by the cornua of the uterusof the cow. The normal longitudinal folds in the nuicous mem-brane are entirely obliterated, and in their place there appearnumerous transverse ridges in the muscular walls.
