parently a blood clot. Urine brown, tinged with blood. Micro¬ 
scopic examination shows vast numbers of epithelial cells and 
aggregations of reddish granules which seemed to be broken 
down blood-globules. 
This animal had been on pasture and had been affected with 
colicky pains for several days before death; it had eaten little 
during this time, so that the ingestion of arsenic had been small, 
which doubtless accounts for the comparatively small quantity en¬ 
countered in the liver. 
The writer is of the opinion that this was a case of arsenical 
poisoning, and he is further of the opinion that the congestion of 
the trachea and lungs, the hemorrhages into the lungs and under 
the pleura, the large effusion in the pericardium, the hemorrhages 
in the stomach, the great congestion of the kidneys, the conges¬ 
tion and hemorrhage of the bladder, the large quantity of epithe¬ 
lium in the urine and the great congestion of the spleen and liver 
would not have been caused by a thrombus of the anterior mesen¬ 
teric artery, even had the obstruction been complete. On the 
other hand, such lesions are common in acute arsenical poisoning. 
The Excretion of Arsenic by the Mammary Glands. 
The quantity of arsenic excreted with the milk is of much in¬ 
terest from several points of view; it is interesting to know that a 
considerable portion of the ingested arsenic may be excreted 
through this channel; it gives some indication as to whether 
arsenic is being absorbed from the digestive tract in dangerous 
quantities, and it furnishes a basis for deciding whether the milk 
is safe for consumption as human food. As this line of investi¬ 
gation was foreign to the legal inquiry then in progress, it was 
not pursued further than was necessary to establish the fact that 
arsenic was being excreted in considerable quantities with the 
milk, and that this subject was worthy of attention from a sani¬ 
tary point of view.
