94 CONTAGIOUS DISEASES OF DOMESTICATED ANIMALS. 



was present. A i)inkisli color was diffused over the ineuibraue of the 

 mouth and tongue. Breathing accelerated ; temperature 101.5°. In 

 withdrawing the instrument from the rectum an ulcer was exposed to 

 view, which bled slightly. (On the following day 1 saw this animal 

 again and found the conditions unchanged, except that the blisters in 

 the mouth had assumed the characteristic brownish-yellow color, simi- 

 lar to those found in the mouths of the worst cases. lu the course of 

 ten days this animal had about recovered.) On this day I noticed sev- 

 eral animals frothing at the mouth, although they showed but slight in- 

 dications of lameness, but for want of proper assistance was unable to 

 catch them for closer inspection. Ou the Goodrich farm I found a num- 

 ber of cows and heifers to have discharges from the vagina, accom- 

 panied by thickeniug ecchymosis, or ulcerations of the mucous mem- 

 brane of the vaginal walls. I noticed also small blood-clots and mucus 

 or recently-dropped fecen. 



On Monday, the 10th, I looked again for recent cases, but did not 

 succeed in finding any. 



Mr. Hindman gave me the following history : He has lived eight 

 years on this place, and has been engaged in raising and feeding stock 

 during taat time. He never before had any disease among his cattle. 

 He took into a herd 5 miles, east, which was in charge of George 

 Grant, 72 head of cattle last spring, and on the 10th of October brought 

 home 78 head. During the summer 2 died and 5 were sold. Since the 

 return of the 78 head 8 calves have been born. These cattle, since the 

 10th of October, have been kept in a feed-lot, sheltered by timber, south 

 and east of the house. They derived their drinking water from a pond 

 (surface water) located in a field 20 rods north of the house, and at 

 about the same distance from the residence and yards of Mr. Keith. 

 On New Year's week he took all the cattle, except a few cows and a 

 bull, out of the feed-lots, driving them through a gate south of the 

 house, and then drove them down the public road a distance of 40 

 rods and turned them into a stalk-field and meadow, from whence they 

 could again return through a gap in the hedge to the old feed-lot and 

 drinking place. He ke])t 3 cows and a bull in a small field north of the 

 house, from which they went to the same pond for water as did the other 

 cattle. On or about the 10th of January one of these milch cows be- 

 came lame iu one hind foot, and was yet lame when 1 saw her, but mani- 

 fested no indications of losing any part of her foot. The next cases of 

 lameness ai)i)eared on the 11th or loth of February, the day after 

 a heavy rain and sleet storm. On that morning a number of cattle 

 were laniCj and new cases appeared daily for a number of days there- 

 after. The lameness attacked cattle regardless of age, sex, or condi- 

 tion, old as well as young, and just as severely. As soon as they be- 

 came too lame to get around to feed and water they were driven into 

 a small yard on the east side of the house, where they had a covered 

 shed lor siielter, and feed and water was carried to them. In this shed
