tM [ CONTAOIOUS DISEASKS OF DOMESTICATED ANIMALS. 



to make a post mortem examination, even if the owner was absent. We 

 found her ivstin^j upon tlie sternum, the head thrown back to the right 

 side. She was i)r<)p[)ed up in this way by tlie nose touching the ground. 

 Cadaveric rigidity had ah'eady set in; drops of blood were dried on tlie 

 liair along the sides of the neck and tianks. 



We turned her over on the side and I opened her in the usual way. 

 I found the lower i)arts of the posterior portion of tlie lungs in a state 

 of red hepatization, and considerable serous effusion had collected in 

 the thoracic cavity. The endocardium was heavily congested, thickened 

 and discolored; the fleshy pillars in the ventricles were of a dark purple 

 color, and the auricular appendages were extensively ecchymosed. 

 Weight of liver, 20 iiounds. Weight of spleen, 4 pounds. The gall- 

 bladder contained one qnart of very dark green bile, which was. of a 

 granular appearance. 



A serous and bloody infiltration was discovered surrounding the kid- 

 neys. The urine bladder contained a very dark blood-colored urine; 

 specific gravity J. 012; the organ was thickened by capillary congestiou 

 of the mucous coat, and a few ecchymosed spots presented themselves. 

 The contents of the third stomach were very much drier than normal, 

 and the folds presented a congested and irritated appearance; fourth 

 stomach congested, and numerous small erosions and granular elevations 

 were to be seen on the mucous surface. This animal did not present 

 much biliary discoloration of the fat, and the Wood was not as thin and 

 watery as is usual in Southern cattle fever. The uterus contained a 

 fetus about four or five months old; it presented a liver enlarged to 

 three times the normal size; the kidneys intensely congested, and par- 

 tially disorganized by softening and disintegration; splf^en nearly normal 

 in color and size; the pericardial, thoracic, and abdominal cavities con- 

 tained considerable bloody colored effusions of serum. When I was 

 nearly done with the dissection, Mrs. Evans returned, and she told me 

 that the cow had been sick three days. Another cow was sick in the 

 herd; after some lively running we succeeded iu lassoing her; she had 

 b«-eii sick four days; temperature, 104.5°; pulse, 96; nose dry; ropy saliva 

 flowing frotn the mouth. October 20th met Mr. Evans, who reported 

 two additional deaths, and two more sick. He brought 110 head of good 

 grade cattle from Allen County, Kansas, arriving on his present range 

 with them on the 11th of May, Since that time the cattle have not 

 strayed in any direction 3 miles distant from a central point on the range. 

 The first loss occurred on the ord of October, and have died to date, 

 the 20th. 



We next visited Mr. Parsons. He lost some cattle last year, attrib- 

 uted to the bringing in on his range of Indian or Choctaw cattle by 

 Morton and Tolliver. This year he lost 3 out of 80 ; they died in August. 

 October 20th he reports 2 more deaths October 23d reports 2 head of 

 the oil-brand cattle, on the same range witii his, as being sick. Ilink 

 Moore lost 5 out of 7'iO head. Boyd's 'C ittle ran with his for several 

 weeks before the roundup in July.
