150 FEVERS. 



(as Mr. Feron has observed) " the swelling is not always con- 

 fined to the jaw, but the animal frequently breaks out in 

 several places of the body, and at different times^ before 

 the disease sinks; which renders it tedious and trouble- 

 some." This observation is confirmed by Mr. Dick, of 

 Edinburgh, who observes, " although the disease commonly 

 terminates by an abscess under the jaw, yet it may, and 

 occasionally does, give rise to collections of matter on other 

 parts of the surface.'^ To which I may add, that it appears 

 in this character to answer every end it fulfils in the form 

 of strangles. Nay, my observations carry me a step beyond 

 this ; and I now begin to doubt whether any abscess is 

 absolutely necessary to answer the intention nature has in 

 view when subjecting young horses to the disorder. I be- 

 lieve horses have strangle-fever ; but I doubt if every one 

 which has the fever has it accompanied by local abscess. 

 The tumour, however, happens in other parts, as well as in 

 the throat. Mr. Castley^s three cases (to which he could 

 have added '^ many others ") establish this ; and I have now 

 others I could add to them.' 



' The first case mentioned by Mr. Castley is of a bay mare, four years old, 

 admitted for " being very stiff and lame of the near hind extremity :" — '' the 

 following day a painful tumour began to make its appearance on the loose skin 

 of the flank," which grew to " the size of a cricket ball." In ten days it pointed 

 and was opened. Then another formed on the other flank ; which second for- 

 mation it was that fixed Mr. Castley's attention, and marked the constitutional 

 character of the case. They were both ushered in by febrile disturbance, and 

 each discharged about a pint of matter ; after which the mare began to thrive 

 and improve rapidly. There was no sore throat nor any catarrhal symptom. 

 The second was the case of a brown mare who had gone through regular 

 strangles, and was discharged from hospital ; but was re-admitted a fortnight 

 afterwards with symptoms of internal disorder of a visceral character. She died 

 the sixth day afterwards. An abscess was found in the mesentery, which Mr. 

 Castley *' felt no hesitation in calling one of the sequels of strangles." 



The third case was a bay horse, in whom four distinct formations of matter 

 occurred : one under the jaw ; one on the right cheek, one in the near arm ; one 

 on the near quarter. 



" The two last abscesses discharged a quantity of thick pus. Since then the 

 horse has been rapidly improving." ('Veterinarian,' vol. iii, pp. 428-431.) 



To these I will add two cases. In July, 1832, a mare, which had been three 

 months out of the dealer's hands, sickened — became unthrifty, and feverish. I
