SCROFULOUS DISEASE IN PIGS. 
refuses to admit the evils cast upon shoeing by Bracy Clark. 
“ If,” says he, “ as Clark pretends, the shoe and the nails 
hinder the natural expansion of the hoof, and are the source 
of so much disease, I would ask him how it happens that the 
hind feet become exempt, since the shoes and nails are ope- 
rating upon them too, and perhaps in a greater degree ?” 
The reply to the above question, put to Clark, is, that, in 
the first place, the hind feet do not receive the concussion 
the fore feet are constantly subjected to ; and, in the second, 
that the force with which the former strike and impress the 
ground is great enough to counteract and overcome any re- 
striction to expansion the shoe and nails may exert. These 
causes — the absence of one and the presence of the other — 
operate so beneficially for the hind feet that it is notorious we 
rarely look for disease in them ; indeed, we may say, never, 
for either navicularthritis or contraction. In fact, as is 
well observed, in conclusion, by Rey, people exaggerate the 
effects of shoeing while they forget to reckon the mischief 
the foot sustains from use different from its natural usages.

OBSERVATIONS ON SCROFULOUS DISEASE IN PIGS. 
By M. Cauvet, Veterinary Surgeon, at Narbonne. 
The pig, at a young age, and under the influence of certain 
morbid causes, is liable to a disease characterised by the ef- 
fusion of tuberculous matter into different parts of the orgasm, 
with profound alterations in the osseous system. Often 
several organic systems are attacked at once. In every case, 
the seat of the disease appears to be owing to modifications 
of perverted vitality. 
The disease affects young pigs only, and it is especially 
after weaning, and at the time they change their regimen 
that it becomes developed in a more appreciable form, and 
manifests more rapid progress. In every litter the sow has, 
generally there will be one or more young ones less developed 
than the others, as though they inherited debility at birth. 
These, although they may at first thrive and grow like the 
others, so long as circumstances prove favorable, yet oftener
