Cause.—This condition is due to a germ (the Bacillus Cyanogenes) which may occur in rich milk or cream immediately after being drawn or the germ may find its way into the opening of the teat.

Treatment.—Injections into the teat of a solution composed of the following: Hyposulphite of Soda, two drams; Boracic Acid, one dram, dissolved in one pint of boiling water. Permit to cool and inject a small quantity in each teat once or twice a day for three or four days. This will destroy the Blue Milk producing germ without any injuries to the cow udder, or teats.
