This study is an important contribution. It advances greatly our knowledge of the composition of individual samples as influenced by such factors as the mother's state of nutrition, the stage of lactation, the milk yield, the season of the year, the age and parity of the mother. The report is well planned for ready reference. It is divided into two chief sections. One deals with the constituents of human milk and the other with the relation between the constituents studied and nutritional standards. Tables and figures are used to good advantage. The language is clear and concise and easily read. Each subsection is followed by a bibliography of related studies. The report is summarized in a few short pages at the end of the book.
It is impossible to illustrate the many points of special interest to pediatricians, obstetricians and public health workers which are brought out in this book.
