260 VETERINARY MEDICINE AND SURGERY. 



Horses recovering from influenza are sometimes attacked with a skin 

 disease, which consists in the skin being wholly or partially covered with 

 little flattened lumps. In chronic cases, the cuticle peels off and leaves 

 as many bare spots as there were lumps; but more often the lumps disap- 

 pear spontaneously in a short time. 



Rheumatism is an occasional after-result, as are also roaring, whis- 

 tling, and chronic cough. 



STRANGLES. 



Synonym. — Colt distemper. 



Definition. — Strangles is a disease usually attended with an eruptive 

 fever, generally appearing before the horse is five years old. The local 

 symptoms usually manifest themselves in, or in connection Avith, one or 

 other of the glandular structures. Most commonly the submaxillary 

 and parotid glands become inflamed, and suppuration afterwards takes 

 place in the connecting tissue and its neighborhood. 



In favorable cases the tumor usually occurs in the submaxillary space, 

 and terminates in an abscess in the cellular tissue and textures covering 

 the glands. 



Strangles, though a debilitating disease, in general leaves no injurious 

 effects. On the contrary the patient usually thrives Avell afterwards, es- 

 pecially if the suppurative process has gone on favorably. If, however, 

 the eruptive fever is checked by injudicious treatment, or the animal is 

 too weak to throw out the eruj)tion, he Avill not do well. 



Etiology. — There are various theories as to the cause of this disease, 

 but none which satisfactorily account for it. By some it is considered 

 infectious, though this is hardly probable. Few horses escape it alto- 

 gether, but rarely or never have it a second time. 



Symptoms. — The horse is sick and off his feed, and perhaps has a slight 

 catarrh with feverish symptoms. The coat becomes harsh and staring 

 and the animal hide bound. In a day or two the glands under the jaw or 

 behind the ear begin to swell. Partly from the effect of the fever which 

 accomj)anies the attack, and i)artly from symi^athy, the throat also becomes 

 sore; and although evidently thirsty, there is much hesitation and diffi- 

 culty in swallo'ving, with much slobbering and some acceleration of the 

 breathing. AVilliams describes the symptoms as follows, viz. :
