The present work falls naturally into several distinct parts. In the first place the history of the movement has been described in some detail. It was found difficult to confine the history to the development of the clinic only as, after all, the clinic is only part of a larger scheme. The historical portion therefore treats of the development of the entire Maternity and Child Welfare movement from the earliest times. Some apology is perhaps required if the reader finds the historical portion lengthy but the material has been so generous and interesting that it was felt a shorter sketch would not do the matter justice. During the earlier portions of the history it was convenient to describe both the Maternity and Infant parts of the movement together; but with the advent of the twentieth century the development of the two parts became so rapid and involved that it was more convenient to describe from that point each part of the movement separately. In the succeeding portions of the work the Infant Welfare and Ante Natal Clinic are discussed. The functions, future development and value of the clinic are considered in somedetail as well as the shortcomings of the present system. The remaining portions of the work are concerned with a short summary in which the principal findings are embodied. A bibliography of the various books and papers consulted or read is appended.
