THE THROAT AND NECK 147 



sharp curved hook or bent needle and thread, and an ehiptical 

 or circular piece excised to make a hole sufficiently large for 

 the insertion of the tube. The tube— which may be made 

 of silver-plated metal, aluminium, celluloid, or vulcanite — is 

 then placed in the trachea and fixed in position. 



hor temporary purposes a piece of bent glass tubing, held 

 in position by tapes tied around the patient's neck, improvises 

 very well.^ 



The subject of the illustration (Fig. 116) was a collie pup, apparently 

 dying from asphyxia owing to the presence of thick mucus in the nostrils ; 

 and, in fact, the animal was said by the owner to be already dead. The 

 tube was hurriedly inserted, artificial respiration was applied, and 

 restoratives were administered, the patient making an excellent recovery. 

 The tube was worn only for a few days. 



Foreig-n Bodies around the Neck. 



It is by no means uncommon for the practitioner to be 

 consulted with reference to a curioush' regular and con- 

 tinuous wound round the neck. The animal may be showing 

 pain, and trying to rend the part ^\•ith its paws, or this stage 

 ma}' have passed off. In extreme cases the respiration may 

 be distressed. Numerous instances have been met with in 

 which the cause of the trouble has been an indiarubber ring 

 or a piece of thread or twine (especialh* the first named), 

 ^\■hich has been slipped on the neck b)- children, and re- 

 mained undetected until it has completely buried itself under 

 the skin.^ A rabbit-snare has on more than one occasion 

 been known to be complete]}' buried in the skin of a cat 

 before the animal became sufficientl}' ill to attract attention. 



In the case illustrated (Fig. 117), the rubber ring depicted (actual size) 

 was completely buried except in two or three small ulcerating spots, and 

 the pressure on the trachea had aire idy progressed to such an extent that
