eruption, pervading the same parts of tne skin as in surfeit, 
commencing, however, on the neck, at the root of the mane. 
Some time after these lumps have appeared, a vesicle is 
formed on the surface of each, which in time breaks, and 
then the hair and cuticle fall off, leaving bare spots covered 
with scurf, from beneath which a foetid fluid issues, and 
then the scurf changes to a scab, which also soon peels off, 
leaving a larger bare space. This in some instances is 
followed by another scab ; but more frequently there is left 
after the first scab peels off, a bare greasy-feeling spot, 
which is followed by a thickening of the skin, accompanied 
by tenderness and itchiness ; this soon becomes puckered 
and folded to a greater or less degree. 
As above noticed, this complaint commences on the neck, 
and its earliest stage may be observed before the eruption 
has come out, by the horse exhibiting symptoms of itchiness 
in the neck, and rubbing it against the different parts of the 
stall. To ascertain if it is this disease coming on, let the 
hairs of the mane be pulled, and it will be found that they 
are plucked out with ease. The disease generally creeps 
up the head, and downwards to the withers and back, and 
not unfrequently spreads over the entire body of the 
animal. 
Cause. —A chief cause for this complaint is a general 
want of cleanliness in dressing the animal, as well as keep¬ 
ing the stable free from noxious vapours, which being 
inhaled into the lungs, carry contamination through the 
system generally. It may also be brought on by poverty of 
living, which is manifested by the complaint so often ap¬ 
pearing in horses that have been half-starved, and otherwise 
ill kept. Many breeders are so parsimonious that they 
turn out their colts into a straw-yard, which they keep 
scantily supplied, without considering the damage they are
