TESTICLES^ DISEASED. ...TETANUS. 307 



Testicles y diseased. 



Sometimes dogs are attacked with a redness and swelling 

 of the scrotum or bag, which is nothing more than a variety 

 of acute mange, and is treated of under that complaint, and 

 also under Scrotum, inflamed. But, sometimes, the tes- 

 ticles themselves may become enlarged and indurated, which 

 is a much more serious disease. — See Castration and Scir- 



RHUS. 



Tetanus^ or Locked Jaw. 



It is remarkable, that although dogs are very subject to 

 various spasmodic affections, yet to that called tetanus, or 

 locked -jaw, they are so little so, that 1 never met with more 

 than three cases of it among many thousands of diseased 

 dogs. These are, however, sufficient to establish the suscep- 

 tibility of the dog to the complaint. Two of these cases 

 were idiopathic, one being apparently occasioned by expo- 

 sure to cold air all night: in the other, the cause was obscure. 

 The third was of that kind called symptomatic, and arose 

 ' from external injury done to one of the feet. In each of 

 these cases the convulsive spasm was extreme, and the ri- 

 gidity universal but not intense. In one case the jaw was 

 only partially locked. 



Both warm and cold bathings were tried ; large doses of 

 opium and camphor w^ere thrown up in clysters ; and, in one 

 case, these articles were poured down the throat also. The 

 sj,ine of one was blistered. Stimulating frictions were ap- 

 phed to all, but in neither case with any salutary effect. 



In the hog and sheep, tetanus is very apt to follow wounds 

 of the head ; but it is, I believe, invariably fatal in both, 

 and it is remarkable, that, in these animals, the tetanic at- 

 tacks are periodical and not constant.
