ELECTROCUTION IN HORSES.

the brain. The medullary and cerebral substances were abso¬ 
lutely normal, the cephalo-rachidian fluid had its normal color¬ 
ation ; the choroid plexuses were red, as they are in all horses 
which have not been bled. 
The second horse presented nothing on the peritoneum, liver, 
spleen and superenal capsules. On the superior face of the right 
kidney there exists a wide ecchymosis, but its parenchyma was 
healthy ; also the left kidney. 
The stomach was normal. The small intestines presented, 
like the first, lesions quite extensive ; circumvolutions, 50 centi¬ 
meters in length, were found between sound parts of the organ ; 
they had their walls thinned out, rosy in color, with soft un¬ 
folded mucous membranes. All the other organs were healthy. 
In the thorax the parietal pleura was healthy, the visceral 
presented a few ecchymoses ; there were some also on the exter¬ 
nal face of the pericardium, while the visceral showed some 
petechise. Very slight lesions existed on the endocardium ; on 
the mitral valve were ecchymoses. 
The blood had all the characters of asphyxic blood. In the 
nervous system nothing, nor on the meninges, the medullary or 
encephalic structures ; the choroid plexuses were slightly con¬ 
gested. 
Altogether, very limited lesions, truly visible only on the 
small intestines and the blood.

SECOND EXPERIMENT. 
In this experiment it was decided by the Committee to (1) 
kill one horse with a current of 550 to 600 volts, and make the 
post-mortem 36 or 48 hours after, and (2) expose another to a 
current more and more severe until life was in danger, and then 
keep him for several weeks. 
Somewhat similar preparations to those used in the first ex¬ 
periment being made, the first animal, an aged bay mare, was 
first exposed to a current of 100 volts. She flexed the knees 
suddenly when the shock struck her, made a jump sideways and 
walked off. With 200 volts she again trembled on her knees,
