RUPTURE OF THE DIAPHRAGM. 
The instrument used by Dr. P. consists of a metallic tube six 
inches long and one and a half inch in diameter. A piston works 
inside, air-tight. At the extremity are two openings, furnished 
with flexible tubes : upon each there is a stop-cock. One of the 
flexible tubes is connected with a vessel containing the aether ; the 
other is introduced into the rectum. The vessel containing the 
aether is placed in water heated to the temperature of 40 degrees 
Reaumur. "When the piston is drawn up, the cock leading to the 
aether is opened, and the other is shut ; when filled, that is closed, 
and the tube leading to the rectum is opened. The vapour is then 
forced in by the piston, which is repeated until the whole is intro- 
duced. Before commencing, it is necessary to give the patient a 
clyster of soap and water. 
RUPTURE OF THE DIAPHRAGM.

I send the following case for insertion in The Veterinarian, 
should it be deemed of sufficient importance; considering that 
publishing a multiplicity of cases, and recording their symptoms, 
is the only sure way of arriving at a correct diagnosis. 
May Y2th . — A farm horse, six years old, the property of James 
Harris, Esq., Vineham, was attacked about seven o’clock A. M. 
(after having drawn home a load of lime) with what the waggoner 
considered colic ; for which he was drenched with warm beer and 
gin, and afterwards with some Glauber salts, and was bled twice, 
but not to a large amount. The horse getting no better, about 
four o’clock P. M. my services were required. I likewise con- 
sidered it a case of colic, and treated it accordingly. About eight 
o’clock I left him, he then appearing free from pain, and being up, 
and looking quite comfortable, eating his mash. The pulse, I 
should have stated, was very little accelerated. 
13 th . — I saw him this afternoon, and found him fearfully worse. 
Pulse very frequent ; up and down continually ; breathing hur- 
ried ; mucous membranes blanched. I now considered him labouring 
under an attack of enteritis. 
Treatment . — Venesection to syncope; blister the abdomen; 
give opium, &c. 
14 th . — No better. Bleeding repeated. Give opium, &c. and re- 
peat blister. The horse occasionally sits upon his haunches. 
15th. — To-day he sits a great deal upon his haunches, which, I
