756 OPEEATIONS UPON THE EYE AND EAK, 



cavity until all granulations, suppuration and inflammatory proc- 

 esses in and about the wound have ceased. 



To put the artificial eye in place the upper lid is raised and the 

 the border of the artificial organ placed underneath it ; in the 

 meanwhile the lower lid is drawn downward and the correspond- 

 ing border of the eye jjushed on its internal face. The eye is in 

 place, esjDecially if after its introduction the animal makes a few 

 motions with his lids, all the folds of which are soon removed. 

 To remove the eye the lower lid is drawn downward, and it is dis- 

 lodged by passing a blunt probe under it toward its posterior face. 

 The artificial eye will not need removal of tener than once in eight 

 or ten days. If worn too long there might be danger, with cer- 

 tain materials, of softening. The advantage of having an alter- 

 nate eye will, upon reflection, become obvious. 



ON THE EAR. 



Amputation. 



Usually, only horses and dogs are subjected to this oj)era- 

 tion. 



With the horse, the object is commonly either the correction 

 of a deformity, or the cui'e of disease or injury. 



When performed upon the dog, it is principally as an opera- 

 tion of fashion — so-called — or in compliance with some prevalent 

 caprice relating to a supposed improvement in the appearance of 

 the animal. Yet with these it must at times, of course, become 

 necessary for the repair of an accident. It should be understood 

 that the seat of the operation is in aU cases the cartilage of the 

 concha. 



Amputation in Horses. — The amputation may be either partial 

 or complete. One ear may exceed the other in size, and it may 

 become necessary to trim down the larger for the sake of estab- 

 lishing symmetry between the mismatched pair with the knife. 

 Or both may be similarly misshapen, and a partial amputation of 

 both may be, therefore, indicated, for the same aesthetic reason as 

 that which influenced in the other case. 



This operation is seldom, if ever, performed at the present 

 time. The comj)lete amputation is indicated in cases where the 

 cartilage is affected with pathological degenerations, and especially 

 when these exist toward its base.
