Animal glycerin, half a pint; chloride of zinc, two drachms; strong

CRIB-BITING. 
Cause.—Sameness of food and unhealthy stables, or indigestion. 
Symptoms.—Placing the upper incisors against some support, and, 
with some effort, emitting a small portion of gas. 
Treatment.—Place a lump of rock-salt in the manger; if that is not

magnesia upon it, and mingle a handful of ground oak-bark with each 
feed of corn. Purify the ventilation of the stable before these remedies
