by _artificial_ feeding--the babe not having the advantage of the
mother's milk--it is really surprising how rapidly a wet-nurse--if the
case has not been too long deferred--will effect a cure, where all
other means have been tried and have failed. The effect has been truly
magical! In a severe case of thrush pure air and thorough ventilation
are essential to recovery.

There is, then, a language in the cry of an infant, which to a mother
is the most interesting of all languages, and which a thoughtful
medical man can well interpret. The cry of a child, to an experienced
