16 THE EQUINE HOSPITAL FORMULARY. 



Anaesthetics. 



General. 



Chloroform. — From two to four fluid ounces may generally 

 be necessary ; but not uncommonly as much as six fluid 

 ounces may be requisite. The safest method of adminis- 

 tering is by means of the chloroform-cap invented by the 

 late Mr. D. Gresswell, or else by Mr. Cox's chloroform-cap. 

 Whilst giving chloroform, the great point is to watch most 

 carefully both the respirations and the pulse. It is best 

 to commence with the vapour diluted with air, by holding 

 the chloroform at first away from the nostrils. When the 

 animal is beginning to be affected, then apply the cap. 



Mixture. 



Ether, three parts. 

 Chloroform, one part. 



For dogs, it is best to administer either (1) pure ether, or 

 (2) a mixture of one duid part of chloroform and four fluid 

 parts of ether. 



Local. 



(1) Hydrochlorate of cocaine, two to four parts. 

 Water, one hundred parts. 



This aqueous solution may be most useful for producing 

 local anaesthesia when it is required to perform an operation 

 on the eye. 



(2) Hydrochlorate of cocaine, from four to twenty parts. 

 Water, one hundred parts. 



This stronger aqueous solution may be used for producing 

 anassthesia, when it is required to perform an operation on 

 some part of the body other than the eye.
