Equine Influenza. Adynamic Catarrhal Fever of Solipeds, 171 



lenpe of the heart action and the weakness of the pulse, circula- 

 tory stimulants are called for. Digitalis 10 grains twice daily, 

 strophanthus tincture i J^ dr. , strophanthin subcutem ]^ grain, 

 caffeine 5 grains, veratrine ^Xh grain, or strychnia 2 grains. 



Nervous symptoms will exceptionally demand the application of 

 cold water or even ice or snow to the head, with counter-irritants 

 to the sides of the neck or chest, and the internal use of bromides, 

 iodides", chloral or other nerve sedative. 



Other complications must be treated according to their indica- 

 tions. 



As the skin becomes cooler and more moist, and the pulse 

 slower and fuller, a tonic and stimulating treatment may be desir- 

 able. Gentian 4 drs., saltpeter 4 drs., sal-ammoniac 2 drs. may 

 be given night and morning, or in case of great debility ammonia 

 carbonate may replace the sal-ammoniac. Or the gentian may be 

 replaced by nux vomica, and the ammoniacal preparations by 

 alcoholic ones. 



When prostration becomes extreme and stimulants and bitters 

 appear inadequate, transfusion of blood from a healthy horse may 

 save the patient's life, or a normal salt solution sterilized may 

 be introduced into the vein. 



The first method is accomplished through a caouchouc tube 

 with a short tube of silver inserted in each end ; the jugular 

 groove of each horse is washed and disinfected, and the vein 

 opened-; the tube disinfected with a salicylic acid solution, and 

 cleared out with boiled water is inserted upward into the vein of 

 the sound horse, and when the blood begins to flow the other end 

 is inserted downward into the vein of the sick one. In this way 

 the blood is allowed to flow from the one to the other, the finger 

 being kept on the pulse of the patient to detect any faltering, 

 which like heaving up of the head or rolling of the eyes, may be 

 taken to indicate undue arterial tension, or disturbed brain circu- 

 lation, and should be the signal for an arrest of the flow. To 

 effect this, pinch the tube in the centre, and wait a minute or so ; 

 if the symptoms subside the current may be reopened and a little 

 more carefully admitted, but if not the tube may be withdrawn 

 and the wounds pinned up. 



The normal salt solution, .6 per cent., is sterilized by boiling, 

 and placed in a sterilized vessel where it is allowed to cool to the
