THE MODERN IIORSE DOCTOR. 119 



eliminated. Diminution in function, or suppressed cutaneous 

 exhalation, excites instinctive movements in the tissues of kindred 

 functions, and thus the discharge from the kidneys may be very 

 large. 



This author has long since, and continues, to discountenance 

 any unnecessary medication, believing that it is the duty of every 

 physician to know when to do nothing — "let well alone." In a 

 case of this character, when it has only existed for a short time, 

 and there be no perceptible alteration in the health of the animal, 

 medicine is actually unnecessary. 



Strict attention, however, should be paid to stable management ; 

 if the animal is located in a stable or barn, the temperature of 

 which is much below that of the body,* let him be removed to a 

 warmer place, and clothed with a blanket, if necessary ; the more 

 fluid we draw from the surface, the less will there be left for the 

 kidneys to eliminate; and this cannot be accomplished without 

 heat. 



Attention must also be given to the quality of the food, and 

 water; the former must be of the best kind, and the latter pure 

 and fresh. Changes in the kind of food will often be of benefit. 



INFLAMMATION OF THE BLADDER — (Cystites.) 



Inflammation of the bladder is not in all cases to be considered 

 as a primary disease, but arises in consequence of disease in the 

 adjacent parts, or from calculi within its cavity. The urine may 



* " Every impression of cold admitted to the surface below the point of tem- 

 perature that the subject has been accustomed to, instantly withdraws from tbe 

 body a just proportion of its caloric; and as this is taken away, so in proportion 

 there is an assault made on the regularity of the functional exercise : although 

 it may not amount to disease, yet the system is more exposed to other hurtful 

 agents. 



" The effect of incompatible degrees of cold is to condense and contract the 

 dermoid tissue, to embarrass the exhalations on the surface. When incompati- 

 ble degrees of cold are often reapplied, and followed suddenly by heat, the 

 tissues acquire an increase of sensibility, by which they are more likely to be 

 acted on by a subsequent exposure, and indeed to other exciting causes". Hence 

 arises a state of predisposition, and cold in this instance becomes merely a 

 remote cause of disease. But remote causes rarely produce active disease with- 

 out some exciting cause, and on a repetition of the exposure to cold, it may 

 become the exciting cause." — Gallup.
