CANINE AND FELINE SURGERY 



The secret of success with chloroform is to alloiv plenty of 

 air, and only just a sujfcicncy of ivell-diliited chloroform vapotir 

 for the purpose required. The duster must on no account be 

 folded upon itself, one thickness of the cloth being ample, and 

 the anaesthetic applied gradually from the drop-bottle. 



The wire muzzle is useful, because it forms a framework 

 upon \\hich to rest the duster, and protects the face from 

 the irritant effects of any chloroform which would otherwise 

 come in contact with the skin or eyes. For small animals 

 an improvised apparatus can be made by placing a piece of 

 blotting-paper or cotton-wool soaked in chloroform at the 



bottom of a tumbler or galli- 

 pot, and holding it to the 

 animal's nose ; or the animal 

 may be placed under a bell- 

 jar, or in an air-tight box with 

 a glass lid, into which there 

 is placed cotton-wool or some 

 material soaked in the anaes- 

 thetic. 



The two latter methods, 

 however, require great care, and are not very convenient 

 for prolonged operations. 



The inhalers suitable for canine work are of three chief 

 patterns, varying somewhat in their construction and in the 

 amount of vapour which they give off. 



The advantages of an inhaler are, that only the vapour 

 comes in contact with the patient's nostrils (there being thus 

 no fear of irritant effects), the anaesthetic is well mixed with 

 air in tolerably constant proportions before being breathed, 

 the amount allowed can be adjusted with great delicacy, and 

 the risk of overdose is thus minimized ; the quantity, too, of 

 chloroform used is considerably less, as the amount wasted 

 is exceeding]}' small. 



The first apparatus is so devised that it allows 6 or 8
