showed a morning temperature of 38. S° C, and an afternoon 

 temperature of 40.8° C. This animal was immediately removed 

 and was placed with the sick animals. Its blood was also ex- 

 amined for surra with negative findings. 



On July 15, 1915, cow 3929 refused food and had a depressed 

 appearance. On July 16 this animal presented a very depressed 

 appearance, but remained standing and spread its legs as if 

 trying to brace itself to keep from falling; the pulse was 106 

 per minute; its body was covered with flies, which it made no 

 effort to drive away (Plate I, fig. 1). Since surra could not be 

 found and the animal did not present the clinical picture of 

 rinderpest, further blood examinations were made, and at this 

 time bodies similar to Anaplasma marginale were located, about 

 30 per cent of the red corpuscles being infected. 



On July 17 the animal was in a stupor; the respiration was 

 slow and sonorous. It remained standing with its legs spread 

 and its body leaning against the stall. It appeared to lose 

 consciousness with its eyes open and would start to fall, but 

 would recover itself (Plate I, fig. 2). The pulse was 98 per 

 minute and wiry, and pronounced oedema was present under 

 the jaw. The animal was covered with flies, which it made no 

 effort to drive away. There was practically no response on 

 trying to rouse the animal. On the afternoon of the 17th its 

 temperature was 37.4° C, which is subnormal. As it was feared 

 the animal would die during the night and as it was desired 

 to perform the autopsy while the body was in a fresh condition, 

 the animal was led out and killed. When led, it was very weak, 

 moved with great difficulty, and had to be helped by a man on 

 either side to keep it from falling ; when standing, it did not need 

 any assistance, as it kept its legs well spread for support (Plate 

 I, fig. 3). 



Upon autopsy the blood was found to be very ansemic, having 

 the appearance of slightly hsemolyzed blood. All the visible mu- 

 cous membranes were pale. There were epicardial hemorrhages 

 at the apex of the heart. The endocardium was pale and bluish, 

 and there was a light red clot in both ventricles. The flesh, 

 in general, was pale and bloodless. The lungs were distended 

 and very pale. 



A marked gelatinous infiltration was present, extending along 

 the upper part of the throat and under the lower jaw. 



Practically all the lymphatics were swollen and cedematous, 

 exuding a watery serous material upon section. The fat cover- 

 ing the omentum and around the intestines was yellow, as if 

 discolored with bile. The gall bladder was markedly distended.
