Excerpt from Studies in Child Development: A Manual for Mothers and Mother's ClubsIt may be noted that, in view of the many sources from which the material of this book has been drawn, there are comparatively few quotation marks. The reason for this is that, in most cases, it has seemed necessary to adapt the material in a greater or less degree to the pur pose of the book. I trust, however, that there has been no failure to give full credit to each and every author from whom the ideas or data have been drawn. For the most part the references will be found at the foot of the page. In some chapters, however, the entire discus sion has been based upon the work of one or more authors.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
