Itch and Mange. 



ITCH, mange, and scabies are essentially local affections of the 

 skin, and are occasioned by the presence of j^arasites known 

 as " sarcojites-equi." The eruption ensuing on the skin of a horse, 



when subject to this aifection, is very 

 similar to the apjjearance of itch in man, 

 and probably is just as tormenting to 

 the animal as in the case of his master. 

 Numerous cases are recorded of trans' 

 mission of itch from horse to man, and, 

 when so acquired, it is impossible to dis- 

 tino;uish it from the human itch. Some 

 persons suffer severely when attending 

 mangy horses, but a clean person or clean 

 horse are not apt to take the disease. It 

 is well known that a healthy and clean 

 horse may stand for weeks near a mangy 

 one without taking the disease, showing, 

 very conclusively, that the best preventive measures are those 

 which promote health and cleanliness. As the English groom 

 Bays, " plenty of elbow-grease, by means of brush and curry-comb, 

 on the skin of the horse ; regular daily exercise, pure air in the 

 stable, and a sufficiency of good digestible food are sovereign 

 remedies against itch and mange." This, we presume, is all the
