The best food for an infant is its mother's milk; in its absence comes milk properly modified. Up to the present, this has been difficult of accomplishment. The Walker-Gordon Company has set a standard of what can be done in this direction, and now the Sheffield Farms Company, of New York, has opened a laboratory for the modification of milk. But such laboratories are situated in only a few of the larger cities, and their product is so expensive that their usefulness must necessarily be limited.
The modification of milk at home entails much elaborate calculation on the part of the physician; much patience and intelligence on the part of mother or nurse; methods so crude for the most part as to render the procedure difficult and inaccurate. However, although modified milk is acknowledged to be the best artificial food for an infant, it is comparatively little used.
