but eei-tainly it is untliinlcabk' not to use at least this. With either the 

 II-M-C or morphin, less clilorofonn is required than wliere ehloroform alone 

 is used, and the anesthesia is sufficiently lasting to permit the operator to 

 Ijerform the wliole operation, onee deep anesthesia is induced, without 

 further administration of ehloroform. This is a g-reat advantage where the 

 ser-^ices of a skilled assistant are not available. AVliere skilled assistance 

 is available, A. C. E., ether, or A. ('. E. and aromatic spirits of annnonia 

 have the advantage that the patient recovers from the anesthesia far more 

 quickly. H-M-C, morphin, and atroi)in all three reduce the danger attend- 

 ant upon the administration of chloroform to the dog to almost nil, and the 

 employment of at least one of them should never be neglected. A¥lien 

 skilled assistance is available and one of the other general anesthetics 

 mentioned, i. e., one containing ether, is used, the hypodermic is not neces- 

 sary to reduce the danger incident to the general anesthesia nor is any of 

 them so etfective when the other anesthetics are used.
