This disease may be discovered from the frequent unsuccessful endeavours
of the bird to relieve itself. Aperients will be of use. If a spider
does not produce the desired effect, anoint the vent of the bird with
the head of a pin steeped in linseed oil; this sort of clyster generally
succeeds; but if the disease attacks a bird which eats meal-worms, one
of these, bruised in sweet oil and saffron, is the most certain remedy,
and the bird will swallow it without the least hesitation. Boiled bread
and milk is generally of great use.
