XI g DISEASES OF THE DOMESTIC ANIMALS 



Possibly it may be necessary to make a third injection after a similar 

 interval. Three to ten days after the injection the fever begins and 

 lasts six to eight days, and, in about thirty days, is followed by a 

 milder attack. By the end of forty days the animal is well and 

 may receive the second injection if necessary. The best results are 

 obtained by immunizing six to fifteen month-old animals in the fall 

 or winter. For a full account of the tick and Texas fever the reader 

 is referred to the admirable monograph of Mohler (Bull. No. 78 

 U. S. Bureau of Animal Industry), to which the writer is much 

 indebted. 



Hemophilia. 



Hemophilia is a rare condition seen in the horse, in which 

 there is a congenital tendency to uncontrollable hemorrhage owing 

 to slight wounds and surgical operations, as incisions or castration. 

 One can not foresee and therefore prevent it. 



Treatment. — The treatment should consist in the application of 

 1-1,000 adrenalin solution, by compress, to the part; or the sub- 

 cutaneous injection of the same, diluted with nine parts of sterile, 

 normal, salt solution, into the part to almost any amount. Among 

 other less valuable external measures are the use of very hot or cold 

 water, compression, the application of pure tannic acid or solution 

 of ferric chloride, and last, and least desirable, actual cautery and 

 ligation. Internally, calcium chloride (H., 3ii; D., gr. ii) may be 

 given in solution every two hours to increase the coagulability of 

 the blood. For the same reason a 5 per cent, solution of white 

 gelatin is useful internally or by rectum. Fluidextract of ergot 

 (H., §i; D., 3i) may also be given in water by the mouth. 



For use of blood serum in treatment, see treatment of 

 Hemorrhage (p. 120).
