that direction, according to the constitutional force of the 

 animal — to the predisposition of any organ or set of organs to 

 become affected in any particular manner,— and to the treat- 

 ment which may be pursued at the onset. 



Symptoms. — The first symptoms, which are usually ob- 

 served before the chill proper sets in, may be thus described : — 

 dullness or want of spirits upon the animal entering a stable 

 after a journey ; hanging of the head ; standing fixedly in one 

 place ; taking little or no notice when spoken to ; smelling at 

 the food ; picking amongst it perhaps for a short time, and then 

 leaving it altogether. In addition to these, the eye is dull, and 

 the countenance dejected; the animal grinds his teeth, and 

 breathes quicker than usual, while the pulse is seldom or ever 

 disturbed at the commencement. Presently his coat will begin 

 to prick, and at the same time he will begin to tremble with 

 considerable violence ; his breathing will become more hurried, 

 and this vdll be attended with a harsh, blowing sound in the 

 nasal passages ; the pulse all the time will retain its usual slow, 

 regular beat. This chilly state may continue from half an hour 

 to two hours, or more, — when the patient becomes quieter, the 

 breathing softer, the skin and extremities warmer; and the 

 pulse rises to fifty, or even sixty beats per minute. From this 

 condition, if the animal be judiciously treated, the attack may 

 gradually pass off, and perfect recovery speedily ensue ; or it 

 may pass into Catarrhal Fever, or Pneumonia, or Bronchitis, 

 or Lymphitis, or Laminitis, or Inflammation of the Bowels, 

 or — what is very common — a bad, obstinate Cough. 



Causes. — The causes of Chill may be stated in a few 

 words, viz. : — exposing the animal to cold draughts ; allowing 

 him to drink freely of cold water, in very hot or during very 

 cold weather; exhausting him with labour, and then placing
