SUCCESSFUL PARACENTESIS THORACIS IN A HORSE. 321 
tartar each Jiss, digitalis 3vj, with sufficient linseed meal to form 
six balls, one of which was given three times a day. Clysters 
occasionally ; body and legs to be kept warm ; bran mashes and 
gruel diet. 
10 th. — Symptoms much the same ; blister his sides ; other 
treatment continued. 
II th. — Pulse diminished in volume, and rather intermittent. 
Omit the digitalis ; the other treatment continued. 
1 6th. — >Pulse increasing in strength and frequency. He is now 
very restless, constantly pawing his litter, and attempting to lie 
down, yet afraid to do so; the faeces are thin and fetid. I took 
away three quarts of blood, and prescribed catechu ^j, digitalis 
3ij, opium 3ij, to be made into four balls with linseed meal : one 
to be given night and morning. 
17 th and 18 th. — The irritation abated; pulse 54, and softer; 
dung firmer in consistence. He eats better. Give of nitre and 
emetic tartar each two drachms night and morning. 
22d. — He is very dull ; appetite impaired ; pulse increased in 
frequency ; purging considerable, and emiting a fetid odour. I 
gave one of the following powders three times a day in gruel : 
catechu 3*ij , chalk Jj, opium 3j, with starch injections. 
23 d . — The purging continues ; appetite more impaired ; the 
horse is becoming very weak. Continue the treatment, with the 
addition of half a bottle of port wine to each dose. 
25th. — He is no better, and is rapidly losing flesh, so much so 
as to extinguish all hope of recovery. Give the following powder : 
chalk 3jj, catechu 3j, opium 5j, Peru bark and gentian aa 3ij 
night and morning. 
2 7th. — Purging gradually subsiding; eats better, but is ex- 
tremely emaciated. The wine was omitted yesterday, now dis- 
continue it altogether, but give the medicine as before in gruel. 
28 th. — The dung is now of a firm consistence, and emits the 
common odour ; his appetite is better, but he has great difficulty 
in breathing. On auscultation I found the respiration greatly 
impeded in the right lung, and on percussing the chest it yielded 
a dull sound. On the same night I related the whole history of 
the case to Mr. Dick, who immediately replied, that from the 
account I had given, and the continued purging and rapid loss 
of flesh, he suspected that the inflammation had terminated in 
hydrothorax. 
29 th. — Mr. D. accompanied me to see him ; and after a short 
examination, was confirmed in the opinion he had given on the 
previous evening. The effusion which had taken piace was 
chiefly in the right side, and to a considerable extent; and the 
left was nearly free from it. The operation of paracentesis tho-
