times a day or better if it can be obtained is allium 
or English garlic; the oil of garlic is the most con-

(BRONCHITIS.) 
Under this head we shall take in inflammation 
of trachea as well as the bronchial tubes. Bron- 
chitis is not very common in the pig, although I 
‘have seen some well marked cases of it, especially 
in shoats of from six weeks to three months old, and 
it often proves fatal. It varies very greatly in de-
