Preface To The Third Edition

The text has been revised throughout and some corrections made, as well as numerous additions which have been suggested by later experience.

These relate chiefly to the qualities of cow's milk and its preparations '; the effect of various diluents upon it ; the use of peptonised and pancreatised foods, and the influence of their prolonged use on the development of the scorbutic state.

Preface To The Second Edition

THE present Edition has been revised throughout, and some new matter added to the text, more particularly with regard to the sterilisation of milk, the relation of eruptions of the skin to diet, and other points of practical interest.

The results of the analyses of human milk hitherto made differ so widely in the amount and relative proportions of many of the elements that a fresh determination of these has been thought desirable, and this has been ably carried out for me by my friend and colleague Dr. Luff. The results are based upon the examination of samples from twelve different subjects, each constituent being estimated positively, not by difference. The most recent and improved processes have been adopted, especially in the determination of the proteids and the fat, and the results viii ARTIFICIAL FEEDING OF INFANTS

are no doubt the most exact and reliable yet attained. The proportions for cow's milk have also been corrected by later analyses than those originally adopted, and the figures throughout revised in accordance with the corrected standards. Dr. Luff has also completed his previous analyses of the various foods by determining the amount of lime and of phosphoric acid. For this valuable and indispensable aid in organic analysis I tender my most cordial acknowledgment. My best thanks are also due to Dr. Hope, the Senior Physician to Queen Charlotte's Hospital, and to Dr. W. A. Bond and Dr. E. H. Brock for their kind offices in procuring the necessary supply of human milk.

Preface To The First Edition

The reason and purpose of these Lectures are sufficiently set forth in the introductory portion, and I have here only to express my cordial and sincere thanks for much kind and valuable help received from many sources.

I am especially indebted to my friend and colleague at St. Mary's, Dr. Arthur Luff, for the accurate and repeated analyses of milk and various other foods and preparations which he has made for me ; to Mr. Arthur Savory and Mr. Ekin for similar service ; and to the makers of various articles of diet for information freely and generously supplied.
