Cocaine is equal in its effects to chloroform in many operations where the parts to be removed are not very deep-seated; besides, its use is much more economical, as not only is the drug itself of less expense, but when operating it is not necessary to have a separate attendant to administer it, as is the case when chloroform is given.

Then it is much more easily given (by a hypodermic syringe), and the dog does not resist it at all; whereas, chloroform is resisted by the patient with all its strength. In some cases three or four assistants are required to hold a big dog whilst it is being administered, and I have known some dogs to struggle so violently against taking chloroform that one has been obliged to discontinue giving it, for to have persevered would have endangered the dog’s life. This alone is sufficient reason to make cocaine a more favourable anæsthetic than chloroform.
