234 BOVINE PATHOLOGY. 



be administered, tlie doses being so arranged tliat they 

 may prove refrigerants to the diseased organ. Steaming 

 the mouth is valuable. The animal should always be 

 allowed a bucketful of nitrated water. One of the most 

 serious effects of this disease is that it cuts off the 

 animals food supply. Nutritive enemas must therefore 

 be given with assiduity, and all drinks administered in 

 gruel and with vegetable tonics. When gangrene of the 

 affected organ sets in, but little hope of a favorable result 

 must be entertained. Free incisions must be made into 

 the tongue. Extensive sloughing may remove the dead 

 parts, and the animal retain a portion of the organ 

 sufficient for house-feeding, but generally death takes 

 place. At best these cases are prolonged, the chances 

 of recovery are poor, and the animal will fall away much 

 during the treatment. Under these circumstances, our 

 duty is to suggest immediate slaughter if the animal be 

 in anything like condition in the early stages of a case of 

 glossitis. Gloss anthrax may be confounded with this 

 disorder, but it is more acute. 



Indueation of the Tongue (Scirrlms). — Generally this 

 is the above-described atrophy of the tongue, due to substi- 

 tution of lowly organised fibrous tissue for muscular 

 fibre. Thus, there is no loss of bulk, indeed, the organ is 

 increased in size and very hard, but markedly of contrac- 

 tility. This atrophy may involve part or whole of the 

 organ ; sometimes it affects only the tip, arising without 

 appreciable cause, unpreceded by inflammation. In any 

 case it interferes with prehension ' and mastication, and 

 the animal becomes emaciated, and should, therefore, be 

 slaughtered early. Interference with rumination and ex- 

 cessive salivation are the most marked symptoms. 



Cancer op the Tongue. — In this disease the organ is 

 the seat of small nodules of carcinomatous deposit, which 

 more or less replace the proper substance of the organs, 

 and some of them bulge beneath the mucous membrane 

 of the dorsum. Some undergo softening, and the sub- 

 maxillary and parotid lymphatic glands are generally 

 involved through absorption of cancerous matter. This
