182 ON PARACENTESIS THORACIS. 
30/^.—The tonic medicine has been continued every four hours 
since the 11th. 
From the 30th of June till the 12th July the tonic was exhi¬ 
bited night and morning, and he was exercised for half an hour 
daily. On the 4th of August he went to his duty, and up to 
the present date has been free from any complaint. 
CASE III. 
July 19^A, 1837.—A black troop horse, five years old, was 
seized with inflammation of the lungs. The pulse was 68, and 
very much oppressed, and there was great difficulty of breath¬ 
ing. Seven quarts of blood were abstracted, and two drachms 
and a half of Cape aloes, with two drachms of tartar emetic, 
exhibited. 
20th ,—The symptoms continuing much the same as yes¬ 
terday, four quarts of blood were withdrawn, the chest and 
sides blistered, and half a drachm of digitalis, a drachm of tartar 
emetic, and two drachms of the nitrate of potass ordered to be 
given three times a day.

instead of the former medicine, and he was directed to have bran 
mashes.

bran mashes. The medicine was continued. 
20th, 27th, 2^thj and 20th .—He has taken some grass, and a 
little dry bran and oats mixed ; but his appetite is bad, and 
he is very weak. I therefore discontinued the medicine for¬ 
merly prescribed, and substituted for it a tonic, consisting of a 
drachm of gentian, a drachm of capsicum, the same quantity of 
ginger, and two drachms of cascarilla bark, to be given three 
times a day, with three drachms of the nitrate of potass night and 
morning. 
30?A.—He is worse. The pulse is 70, the respiration hurried, 
and the appetite gone. All the symptoms of hydrothorax ap¬ 
peared, and I acccordingly operated as in the two previous cases, 
and drew eighteen quarts of fluid from the right side, and seven 
from the left. In two hours he was much improved, and ate a 
full allowance of bran and oats. The tonic last mentioned was
