Local Anesthesia with Heated Cocaine Solution.— 
C. (Genoa) recommends in operations lasting- a long time local 
anaesthesia by means of injection of heated cocaine solution 
heated to a temperature of from 50° C. to 55 0 C. This pro¬ 
cedure offers the following advantages: 1. Weaker solutions 
than ordinary are needed when thus heated. 2. Local anaesthesia 
sets in almost immediately. 3. Heated solutions cause the 
subcutaneous connective tissue to become anaesthetic in wider 
zones. 4. Toxic effects are lessened, as one can get along 
with weaker solutions of cocaine when thus heated. Costa as 
a rule uses a solution of only one to two hundred or one to 
two hundred and fifty. Of prime importance is the knowledge 
of the fact that the solution must neither be cooked nor allowed 
to cool too quickly.—( BerL Thierarzt. Woch.) 
Resection of a Strongly Cicatrized Tendo-Achilles. 
—A hunting dog, whose right tendo-achilles had been severed 
by an axe thrown at him, and who gnawed off the bandage 
placed over the wound, was left by his owner to get over his in¬ 
jury as best he could, with the result that the tendo-achilles 
(owing to the excessive motion) after scarring became so length¬ 
ened as to cause great deformity. R. cut sidewise into the 
lengthened scar tissue between the ends of the severed tendon 
and resected a piece 3 cm. long, sewed the unscarred ends of 
the severed tendon together with catgut, then extended the foot 
into its proper position and immobilized it in that position in a 
plaster of Paris splint, with highly satisfactory results.—( BerL

ITALIAN REVIEW. 
A Case of Tuberculous Basilar Leptomeningitis is 
published in the Clinica Veterinarian by Dr. Gerosa Guiseppe, 
who observed it in a bovine which presented only for principal 
symptoms the manner with which it carried its head on one side 
and low to the ground, and which at the post-mortem presented 
the meninges, principally at the base of the brain, covered with 
numerous tuberculous deposits. The singular apparent healthy 
condition of the patient, with the exception of its peculiar mode
