200 ZOOLOGY. 



animal is contagious for man, and for the ox, but no 

 other domestic animal. The dermatoeoptes mange 

 (found more particularly on the inner sides of the 

 legs, and on the genital organs, tail, and mane) does 

 not spread to man or to other domestic animals. Nor 

 is this the case with the dermatophagus mange of the 

 horse (on the fetlocks and adjacent parts of the legs). 



Scabies of the Ox. — The dermatoeoptes mange of 

 the ox (chiefly afifecting the sides of the neck and 

 root of the tail) spreads to men and horses, but not to 

 sheep. The dermatophagus mange (principally on the 

 root of the tail and near the anus) does not seem to 

 be transmitted to man, horse, pig, or dog. 



Scabies of the Sheep. — The dermatoeoptes mange of 

 sheep is not transmitted as a permanent disease to 

 man, nor to other domestic animals (with the exception 

 of the goat). The sarcoptes mange of the sheep 

 (chiefly on the head) causes the itch in man. 



Scabies of the Pig (Sarcoptes) is contagious for the 

 dog, and causes an eruption in man. 



Scabies of the Dog (Sarcoptes) can be caught by 

 man, pig, and horse. 



Scabies of the Cat (Sarcoptes) is contagious for man, 

 horse, ox, dog, and rabbit. 



Scabies of the Rabbit (Sarcoptes) is contagious for 

 man, but this is not so with the dermatoeoptes mange, 

 which flourishes in the external passage of the ear in 

 the rabbit. 



Scabies of the Fowl (Sarcoptes), which afiects the 

 legs of hens, causing thickening of the skin and 

 formation of large spongy crusts, may infect horses. 

 Hen-houses should not be built in stables. 



Remedies. — From the foregoing facts relating to 

 the transmission of scabies from one host to another, 

 the preventive measures at once follow: A mangy 

 animal must not be allowed to come into contact 

 either with another animal of the same kind or with 

 an animal of any other kind for which the disease in
