they lick themselves and others doubtless contribute to this. The 

 frequency of non-coital infection is shown in Numann's cases af- 

 fecting the anus and sheath in oxen ; also in Fenner's long list 

 of cases in 66g non-pregnant cows, in a number of cows in ad- 

 vanced pregnancy and in calves of a few weeks old (Friedberger 

 and Frohner). 



Symptoms. In Cows. After an incubation of one to six, (or 

 exceptionally ten) days, there occur swelling and redness of the 

 lips of the vulva, and the vaginal mucosa with here and there 

 dark red points, and an abundant clear, glairy discharge. The 

 red points may become firm and papular, and an exudate beneath 

 the epithelium transforms them into vesicles at first translucent 

 but later yellow or brown as pus cells accumulate. The clear 

 mucous discharge meanwhile becomes opaque and, as the pustules 

 open, forming sores, yellowish and purulent. This discharge 

 soils the tails and hips, drains out on the back part of the stall 

 and the gutters and is carried by the tail to the udder and to 

 other stock. Itching may be severe and the constant rubbing 

 and switching of the tail, may irritate the sores and cause them 

 to deepen or extend, beside favoring septic infection and local 

 necrotic processes. In such cases there may be more or less 

 fever, impairment of appetite, rumination and digestion, and of 

 the secretion of milk. Abortion is not unknown though excep-' 

 tional. 



Symptoms. In Bull. The matting together of the long hairs 

 of the prepuce may be the first indication of the disease, attended 

 or followed by frequent micturition, or by standing with the tail 

 raised and the accelerator urinse pulsating over the ischiatic arch 

 as if passing urine. The sheath appears swollen, the penis red 

 granular, and angry, with red Spots, and even the scrotum may 

 be involved in the enlargement. The red points advance as in 

 the female through the different forms of papule, vesicle and 

 pustule to the formation of sores which are more or less red and 

 angry. There may be an indisposition or even inability to pro- 

 tract the penis, and the bull may be tardy to serve, or in case the 

 organ is erected and used, blood may ooze from the respective 

 sores. The disease usually lasts about two weeks, but may 

 recur a few weeks later in connection with a new infection. In 

 aggravated and prolonged cases there may be local septic and
