This bulletin contains a translation of a recent account of the auxiliary schools of Germany. The problem of proper provision for exceptional children and especially for backward children in greater city systems of schools has long been recognized as one of great importance. It has to do not only with the welfare of the children immediately concerned, but with that of all other children in the same schools for the necessity of devoting extraordinary care and attention to a few backward members of the class not infrequently prevents the teacher from giving due care and attention to the larger number of normally endowed members. For both reasons, the city school authorities within the past few years have devoted much attention to ungraded classes and other special provision for these exceptional children. It is believed that an account of a parallel movement in Germany, where it has had a longer history and has reached a more advanced organization will be of use to those who are furthering this movement in America. The lectures of Doctor Maennel here presented in free translation, together with his bibliographies, constitute the best account which Commissioner Elmer Ellsworth Brown has yet seen of this phase of German education and as such he believes the publication will be widely useful in this country. Bibliography and index are included. [The lectures contained in this paper were translated by Fletcher Bascom Dresslar. Best copy available has been provided.]
