After this at intervals of a few minutes evacuation occurred, 
continuing for about an hour and a half. No change in tem¬ 
perature nor respirations, but the pulse was slightly accel¬ 
erated. 
Case IV.—Brown gelding, aged, suffering from spas¬ 
modic colic. Received i gramme of barium chloride dis¬ 
solved in about io cc. of water intravenously. Fasces and 
flatus passed in nine minutes, although straining was noticed 
about one minute after injection. Evacuation took place at 
intervals of a few minutes, continuing for half an hour, 
although there was an abatement of colicky symptoms im¬ 
mediately after the first evacuation. 
Case V.— Bay gelding, five years old, showing similar 
symptoms to preceding case. Received i gramme barium 
chloride dissolved in iocc. water intravenously in the jugular 
vein. Faeces were not passed till twenty minutes had elapsed, 
but after that at intervals of five to fifteen minutes. This case 
did not recover from colic for three hours, although the vio¬ 
lence of the symptoms were much lessened after the first 
evacuation. 
Case VI. The subject in this case was a thoroughbred 
mare, five years old, and in about the fifth month of pregnancy. 
The animal was taken with colic at 9 A.M. Anodynes were 
given with warm water injections. This treatment was con¬ 
tinued throughout the day without any improvement. At 
8 p.M., as a dernier resort , it was decided to use barium chloride, 
the use of which had been delayed on account of the state of 
pregnancy in which the animal was. At 8.15 P.M. an in¬ 
travenous injection of 15 grains in 5 cc. water was given 
intravenously. At 8.19 the first symptoms of the action of 
the drug were noticed. The animal laid down and strained 
violently. Five minutes after flatus and a small quantity of 
almost liquid Feces were passed. Straining continued at in¬ 
tervals for half an hour without the passage of faeces and the 
colicky symptoms apparently aggravated. At 9 P.M. rectal 
injections of warm water were given and an exploration re¬ 
vealed the fact that the colon was filled with faeces which 
were passed a few minutes later. The animal made a com. 
plete recovery.
