Six Repeated Attacks of Periodic Ophthalmia in 161 
Days- Preservation of the Eye. —In Clinic a, l/eterinarici 
A. Trinchera records this case, which is interesting from the 
fact that he succeeded in saving the eye, notwithstanding the 
frequency of the attacks. The treatment was as follows : 
the three first attacks were treated with compresses of camomile 
flower infusion, with boric acid at 3 per cent. The last attack 
received, besides these, application of a collyrium of tropine at 
1 per cent. What will be the end?—( Chnica Veterinaria .) 
Spasm of the Diaphragm [By Mr. Gerosa.] —This is a 
simple case of the affection commonly called u thumps,” and 
which readily subsided, notwithstanding the severity of the 
symptoms and of the attack, to one tracheal injection of 15 cen¬ 
tigrammes of muriate of morphia and a mustard poultice near the 
stomach attachment of the diaphragm.—( Clinica Veterinaria .) 
A Peculiarity of the Technic of Local Anaesthesia 
by Cocaine [By Mr. Tito Costa]. —According to the author, 
local anaesthesia by cocaine, as generally applied, has two weak 
points : 1st. A large dose of the alkaloid has to be used when 
the operation is to take place on extensive surface, hence danger 
of intoxication. 2d. It is necessary to allow a certain lapse of 
time between the moment of the injection of cocaine and that of 
the operation. As a remedy to these objections Mr. Costa uses 
solution of cocaine at 50 or even 55 degrees, and he claims from 
this, the following advantages : 1st. The solution, at 5 or 4 
per cent., has high anaesthetic power. 2d. The local anaesthesia 
shows itself immediately after the injection. 3d. With equal 
quantity of cocained solutions, the insensibilized zone is greater 
in using warm instead of cold solution. 4th. In using a weaker 
dose, which though it produces anaesthesia upon a wider sur¬ 
face, the dangers of intoxication are diminished.—(. Monog .) 
Rupture and Prolapsus of the Left Eye with Com- 
minutive Fracture of Bones of the Face and Deep 
Wound of Lower Jaw. —To the clinics of the Milan school 
numerous cases are daily brought, and Prof. Lonzillotti-Buon- 
santi records many of them. This is one : In double harness 
to a wagon, this is run into by a steam tramway, one of the 
team is killed, the other badly hurt, viz., the left ocular globe is 
partially torn and hangs out of the orbit, the skin of this side 
of the face is lacerated, there is a fracture of the orbital process, 
the lachrymal, zygomatic, and superior part of the upper max-
