154 DISEASES OF THE LUNGS. 



arterial character and frothy, attended with more or less 

 irritation, coughing, or snorting, and perhaps interruption 

 to the breathing; and every time the horse coughs or 

 snorts fresh quantities are ejected, and often through the 

 mouth as well as nose, and mingled with these ejections will 

 sometimes be found various mncosities. The blood does 

 not run in one uniform stream, as in epistaxis, but is 

 influenced by the respiration and position of the head and 

 neck. The other distinctive signs between the two hemor- 

 rhages will be found under epistaxis. In some cases the 

 hemorrhage is attended or followed by febrile disturbance, 

 the breathing proving more or less embarrassed, the pulse 

 quickened, the mouth hot, but the legs deadly cold, or one 

 is cold while another is warm. 



Treatment. — The cases we have in general to treat 

 being such as arise from plethora, and over-action or 

 excitement, we must seek for a remedy which will reduce 

 fulness of blood, and abate over-action and excitement. 

 This is to be found in bloodletting. This is an evil to be 

 met by its like — similia similibus. 



When the condition and powers of the horse are such as 

 will bear it, we may at once abstract a quantity of blood, 

 with the two-fold view of temporarily fainting or depressing 

 the animal, and permanently lowering his constitutional 

 powers; but should he be already in a state of low condi- 

 tion, or have become so reduced by repeated hemorrhages, 

 should bloodletting notwithstanding seem advisable, our ob- 

 ject must be to abstract as large a quantity of blood in as shoiH 

 a time as possible; in order to produce the required approach 

 to syncope, without detracting any great deal of the vital fluid 

 in the present weakly condition of the system. To do this, 

 we should make a very large orifice in the vein ; or, w hat is 

 better practice, draw blood from both sides of the neck at 

 the same time. After bloodletting, take all clothes off the 

 horse, and let them remain off, and dash ice-cold water 

 against his sides and breast : indeed, ice itself applied to 

 them, could it be obtained, would be likely to do good.
