Baron Osten Sacken's autobiographical volume contains so much infor- 

 mation about the earlier work on North American Diptera, and the devel- 

 opment of dipterological science in general, that every student of the order 

 will find it extremely interesting and valuable. His rare and noble devo- 

 tion to science throughout a long career should be an inspiring example.
