VARIOLA IN ANIMALS. 

 HOESE-POX. 



This is identical with cow-pox, being indistingnishable 

 when inoculated on men and cattle. It most frequently at- 

 tacks the limbs, but may affect the face or other part of the 

 body. There is usually some little fever, which, however, 

 passes unnoticed by the owner. Then swelling, heat, and 

 tenderness supervene, commonly in a heel, and firm nodules 

 form, increasing to one-third or one-half inch in diameter, 

 the hair bristles up, and the skin reddens unless previously 

 colored. On the ninth to the twelfth day a limpid fluid 

 oozes from the surface and agglutinates the hairs in yellow- 

 ish scabs, on the removal of which a red, raw depression is 

 seen with the scab fixed in its centre. In three or four days 

 the secretion ceases, the scabs dry up, and the parts heal 

 spontaneously. It is easily transmitted from horse to horse, 

 to man, or to cow. No treatment is reqiiired beyond weak 

 astringent lotions (carbolic acid 1 dr., water 1 quart) or 

 bland ointments.
