_The Frog._--In the north of Lincolnshire the sore mouth with which
babies are often troubled is called _the frog_. And it is a common
practice with mothers to hold a real live frog by one of its hind legs,
and allow it to sprawl about within the mouth of a child so afflicted.
Is the same remarkable custom known elsewhere?
The disease is properly called _the thrush_, and bears some resemblance
to the disorder of the same name which affects _the frog_ of the horse's
foot. I wish someone would unravel this entanglement.
