tain, that it would become the practitioners of our day to utilize 

 it more frequently and extensively than they do. It is available 

 as well as useful in the simplest operations, and may be employed 

 ia the opening of abscesses and cysts ; in the puncture of cold 

 abscesses with the hot irons; in the puncture of the cornea; in neu- 

 rotomy ; in simple incisions of the sMn ; in the removal of small 

 tumors, etc., etc. We have used it with the best results in ureth- 

 rotomy, in caudal myotomy, in amputation of the tail, and the 

 removal of mammary tumors in dogs, etc. Bouley long ago rec- 

 ommended its appUcation to surgical diagnosis, in cases of doubt- 

 ful lameness, an expedient which has recently been introduced into 

 this country by several veterinarians, for the differential diagnosis 

 of shoulder and foot lameness. 



We have remarked that the anesthesia can be produced in 

 several ways, though two are principally in use. Among these 

 properly termed minor and secondary expedients, are the applica- 

 tion of cold water or ice, and coohng or freezing mixtures, and 

 pressure upon the blood-vessels and nerves, which have for years 

 been among the adjunct and agencies of surgical practice, but 

 have given place in recent times to methods more potent and 

 more certain in their effects. Notwithstanding this, however, 

 some mention of their nature and qualities, and the methods of 

 utilizing them will not be out of place, if only as a matter of gen- 

 eral reference, and a case might arise in practice when the infor- 

 mation might become practically valuable.
