 entire loss of appetite and extreme prostration. Eructa- 

 tions of gas frequently passed from the stomach and 

 intestines.

 a second died at 4 p.m., and a third at 10.30 p.m. Before 

 death the animals became still more restless, the pulse was 

 weaker, and finally imperceptible ; the mouth became 

 clammy, and the breath foetid, and they succumbed at 

 length in a state of extreme agony and collapse. One 

 became quite comatose before death, and another had 

 tetanic spasms ; the remaining animal recovered. For a 

 time this horse remained so weak and debilitated as to be 

 incapable of rising without assistance ; at length, however, 

 he made a gradual and apparently complete recovery, but 

 was not able to resume work for three or four months. 



On the following day a careful post-mortem examination 

 was made in each of the three fatal cases. Thorax : The 

 lungs were found to be much congested ; the endocardium 

 of the left ventricle was highly inflamed, and patches of 

 ecchymosis were found studding its surface in several 

 places; the left ventricle was full of black coagulated 

 blood. Ahdominal cavity : The stomach was found to 

 contain much undigested food, and the contents were 

 tinged with blood. The cuticular portion had several small 

 patches of redness, and its walls were eroded, in one of 

 the three cases, near its junction with the villous portion. 

 The villous portion was of a dark-brownish-red hue, being 

 intensely inflamed, and covered in parts with a film of 

 coagulated lymph. 



It was blackened in patches, and in parts was of a dirty 

 yellow colour ; while in some places the walls were much 

 eroded, forming many large eschars, and in other places 

 the mucous membrane was raised in the form of small
