It will be long before we have a biography of Froebel to compare with DeGuimp's Pestalozzi, of which an English translation has just appeared. Meantime we must content ourselves with two long autobiographical letters contained in this volume, which, though incomplete, have yet the peculiar charm that comes from the candid record of genuine impressions. The first of these letters, that to the Duke of Meiningen, has already appeared in English, in a translation by Miss Lucy Wheelock for Barnard's American Journal of Education, since reprinted in pp. 21-48 of his Kindergarten and Child Culture, (see p. 146), and in a small volume under the title.
