SCROFULOUS DISEASE IN PIGS.

evince signs of delicacy, as though they carried along with 
them the marks of precocious dissolution. These are com- 
monly the first attacked, though the disease is not confined 
to them, but sometimes affects pigs having every appearance 
of vigorous health. Seldom do pigs die from the affection 
during their sucking season. They may possibly show signs 
of sickness, or may die of the cold, &c., but scrofulous dis- 
ease has a certain stage to go through, nor can it so early 
manifest itself in any very active form. 
Conformation will indicate predisposition. The most weakly 
subjects, whose chests are narrow, are the most likely to have 
it. Symptoms of debility are seen in such : they carry the 
head low, have a sorrowful aspect, and a tardy walk ; they 
are inattentive to what is passing around them, run slowly, 
and seek warm or sheltered places. When lying in the 
sun, they are not stretched out in the voluptuous manner 
in which the others are ; while their skin, which is full of 
cracks, sticks close to their attenuated bodies, and is covered 
with lice, which seem to have a predisposition for the sick. 
A feeble cough is heard ; the nose is dry and rugose. Soon, 
the appetite fails, the tongue proves dry, and the excretions 
become either hard or diarrhoea-like. The sick are often 
found standing up in the middle of a herd, seldom move out 
of their place, and daily cough with fuller note. The respira- 
tion also becomes disturbed. 
The appetite grows worse and worse, and drinking but 
little, they remain with their lips in the water without swal- 
lowing any. The loss of flesh continues, the cough grows more 
frequent and feeble, the walk unsteady, until at last appe- 
tite fails altogether. The sick remain lying down, and while 
down die under extreme debility. 
During or before those symptoms take place, we discover 
morbid swellings in the bones of the limbs, more particularly 
in the vicinity of the joints. The spongiose tissue becomes 
lardaceous,and the limb assumes an exaggerated and deformed 
development. Sometimes, these are the earliest signs of the 
disease, and the pig that has them never grows and thrives 
like the others. 
This pathological development of the bones, this spongiose , 
as Lobstein calls it, is not confined to the limbs, it has been 
observed on the face ; still, it is the same phenomenon. Some- 
times, the inguinal glands are swollen and painful. 
Death does not always result from the increase of the 
disease. Inter-current affections come on, and particularly 
those accompanied by debility ; some assuming the aspect of 
turn-about in sheep, others of lumbar paralysis. Sometimes
