ture. Their heads are depressed, the ears becoming pendulent. They 

 refuse to eat, and rapidly emaciate, while the yield of milk lessens 

 materially. At the end of a few days a yellowish spot is seen at or 

 near the center of the eye and numerous delicate blood vessels taking 

 their course from near tliis spot in a serpentine manner toward the 

 sclerotic edges of the cornea. In many cases abscesses form, rupture, 

 and discharge their contents. 



Four colored drawings of the appearance of the eye at various 

 stages are given. 



• The inference would be that from the severe inflammation the 

 internal portions of the eye would become diseased. However, it 

 is stated that aside from an oedematous condition of the iris the 

 internal i)ortions of the eye remain absolutely normal. 



In stained sections of the diseased cornea a short, thin bacillus, 

 with romid ends, was observed, in Avhich was either a clear center or 

 a spore. Such an organism, the author says, may represent two 

 organisms with a spore in each, or it may have a belted appearance. 



Unsuccessful attempts to transmit this disease from diseased to 

 healthy cattle are described. 



The treatment advised is to keep the animals in a dark place, with 

 cloths constantly hanging over their eyes kept wet with cold water. 

 To prevent the extension of the malady complete isolation of the 

 diseased from the healthy animals is recommended. 



A singular disease in the external sexv,al organs of cotes (pp. 

 253-255). — In August, 1888, cattle owners near Shickley, Nebraska, 

 Avere alarmed b}^ the appearance of a strange disease in a herd of 

 two hundred and ninety-three cattle, two-thirds of which were cows 

 and heifers. The disease was confined to the females of the herd. 

 It commenced with tumefaction of the fleshy parts of the vulva ; 

 then small, hard nodules would develop, which at first were sharply 

 circumscribed, but eventually coalesced. These nodules soon pre- 

 sented a broken surface Avhich became red and granulous like proud 

 flesh, until the whole vulva would become complicated in this way, 

 with islands of intact skin in places. The malady did not seem to 

 be necessarily fatal, and many cases of healing were reported. The 

 healing, however, was accompanied by the extensive formation of 

 cicatricial tissue, which led to a deforming retraction of the parts. 

 In many cases the urethra became involved and completely closed, so 

 that the animal died in intense agony from retention of the urine 

 and the resulting renal and constitutional complications. The pri- 

 mary origin of the disease is buried in obscurity. Its outbreak in 

 this herd was reported to be due to an old white coav which was said 

 to have been similarly afflicted during four years. 



It was subsequently discovered that a consideral)le outbreak had 

 occurred near Kearney, Nebraska, in the winter of 1886. At that 

 time steers Avere also affected, the disease attacking the tissues around 

 the anus.
