Milk, therefore, must be so much used in these cases in connection with the general treatment I am describing that it is perhaps as well to say more clearly how it is to be employed when given alone or with other food.

I am the more willing to do this because I have learned certain facts as to the effects of milk diet which have, I believe, hitherto escaped observation.

In fact, the study of the therapeutic influence and full results of exclusive diets is yet to be made; nor can I but believe that accurate dietetics will come to be a far more useful part of our means of managing certain cases than as yet seems possible.
We are indebted chiefly to Dr.Karell, of St.Petersburg, for our knowledge of the value of milk as an exclusive diet, and to Dr.Donkin for the extension of Karell's treatment to diabetes.

I shall formulate as curtly as possible the rules to be followed in using milk as an exclusive diet in dyspeptic states, and in anaemia with obesity, and in the latter state uncomplicated by defective haemic conditions.
For fuller statements as to the reasons for the various rules to be observed in using milk, I must refer the reader to Karell's paper and to Donkin's book.
Have the utmost care used as to preservation of the milk employed, and as to the perfect cleansing of all vessels in which it is kept.

Use well-skimmed milk, as fresh as can be had, and, if possible, let it be obtained from the cow twice a day.
