him to produce that wonderfully concise book, "Record of my 

 Life-work in Entomology," a volume which so fittingly rounds 

 out the life-work of this remarkable man. This fascinating 

 book tells, among other things, the many differences existing

 colossal labors stand for him; what I have done has been to 

 place his work in a better light and to give it a more distinct 

 definition, which was due to history." 



Usually he wrote his name C. R. Osten Sacken. In some of

 Sacken. I have adopted the name as it appears in his last 

 publication, printed below his portrait accompanying part 3 

 of his life-work in entomology.
