294 TRANSMISSIBILTY OF TINEA TONSURANS. 
and from man to man, man to wife, and wife to infant. The 
malady attacked the horses and mules about the head, the 
neck, withers, shoulders, and loins. It was attended by 
itching, which was at first thought to be due to acari, but its 
real nature soon became apparent. In one instance, a lad 
16 years of age, who had jumped upon one of the diseased 
animals bare-backed, to take it to water, was affected by the 
disease over the inner surfaces of both thighs—the parts 
which had come into direct contact with the horse’s back. 
It is further worthy of remark that in the cases mentioned by 
Professor Papa, the communicated disease in the non-hairy 
parts of the men was an exaggeration of the ordinary so- 
called herpes circinatus, or properly, tinea circinata, though 
this was not pointed out by him. The patches were observed 
to be studded over, here and there, with small pustular points, 
indicative of a more than usual amount of irritant, and pro¬ 
duced by a plentiful sowing of fungus elements upon the 
skin. 
Referring to the rather common occurrence of transmission 
of this parasitic disease from the calf and ox to man in 
Ireland, Dr. Fox makes the somewhat astounding statement 
that he is not able to put his hand “ upon any save a few 
recorded instances in which man has become infected from 
the horse— an occurrence unknown at the Veterinary 
College” ! ! The pages of the Veterinarian have, in recent 
years, contained the history of such transmissions, and within 
the last two years even, Mr. Nettleship relates its communi¬ 
cability. Cases are within my own knowledge, and since 
1852, foreign veterinary literature furnishes an abundance of 
such occurrences. In that year a horse was brought from 
Normandy to Paris, as a remount for the gendarmerie of the 
Seine; it was affected with the malady, which it communi¬ 
cated to eight horses and five or six men. The disease was 
distinctly recognised in them all. At the commencement of 
1857, the able veterinary professor of the Alfort School, M. 
Reynal, presented a complete account of the affection in the 
horse and ox, and proved its contagiousness. About the 
same period, or a little later, Gerlach, the talented professor of 
the Hanover Veterinary School, described the disease very 
minutely, and particularly as it manifested itself in the ox 
and dog. In the latter the form varies somewhat, according 
to the breed, and the structure of the skin, its colour, and the 
hair with which it is covered. Beneath the crust that accu¬ 
mulates, the skin is dry or humid, thickened or not altered; 
sometimes deprived of hair, sometimes with the hair short 
and stubbly. The disease generally appears in the circular
