Milk may, therefore, be safely asserted to be a sufficient food in itself, even for an adult, if only enough of it be taken.
During the first week or two, exclusive milk diet gives rise to a marked sense of sleepiness.

It causes nearly always, and even for weeks of its use, a white and thick fur on the tongue, and often for a time an unpleasant sweetish taste in the early morning, neither of which need be regarded.

Intense constipation and yellowish stools of a peculiar odor are usual.

Of the former I shall speak in connection with the use of milk in special cases.

The influence of milk on the urinary secretion is more remarkable, and has not been as yet fully studied.
There is, of course, a large flow of urine; and in dropsical cases due to renal maladies this may exceed the ingested fluid and carry away very rapidly the dropsical accumulations.
