"The Works of Blumenbach edited in this volume are the first and third or last edition of his famous Treatise On the Natural Variety of Mankind; which were published in 1775 and 1795 respectively: the Contributions to Natural History, in two parts; and a slight notice of three skulls which appeared in the Gottingische gelehrte Anzeigen of Nov. 1833, only remarkable for being the last printed utterance of the author. Two Memoirs of Blumenbach have been prefixed, which contain together almost everything of interest concerning the circumstances of his life. I have also added an account of his once famous anthropological collection, written by his successor, now himself lately deceased, Professor Rudolph Wagner, one of the original Honorary Fellows of the Anthropological Society, London. Blumenbach has related in the little autobiographical fragment, which has been incorporated by Marx in his memoir, the causes which led to his selection of an anthropological subject as the thesis for his doctoral dissertation"--Preface.
