PREFACE TO THE FIRST EDITION. XXU1

 deem it an honour to take part, no hetter ally than Anthro- 

 pogeny can, it seems. to me, he brought to the assistance

 these facts. 



In order to render these little known facts of germ- 

 history and their causal explanation by tribal history

 academical lectures, on the outlines of the history of 

 human evolution, which I have delivered during the last 

 twelve years in Jena before a mixed audience of students 

 of all faculties, taken down in shorthand by two of that 

 audience, Messrs. Kiessling and Schlawe. The task I
