346 THE CANADIAN ENTOMOLOGIST. 



Loew, now an old and broken-down man, and arrange for the packing and 

 transmittal of the magnificent collection of North American Diptera 

 which had been accumulated there, to the Museum at Cambridge, 

 Massachusetts. It contained the original types of all the species described 

 by Loew, about 1,300 in number, and about 1,600 other species. Most, 



if not all, of these specimens had been sent to Loew by the Baron, with 

 the distinct understanding that they were eventually to be returned to the 

 United States. It may be mentioned that Dr. Loew was well paid for all 

 his services, and that this invaluable collection reached its destination in 

 safety. After accomplishing this task, which, under all the circumstances, 

 was no easy one, the Baron settled down at Heidelberg and continued his 

 studies and researches, extending his field of observation to all parts of 

 the world, and publishing a long series of notable essays and papers as 

 the years went by. 



The present " Record " consists of two parts ; the first contains a 

 brief introductory sketch of the author's life ; the second, which is very 

 much longer, is composed of " twenty-four chapters on historical, 

 biographical, critical and purely entomological subjects connected with 

 his vvork"; the third part, not yet published, will contain a complete list 

 of all his publications. The most interesting feature of the second part, 

 to one who is not a Dipterist, is the author's description of many notable 

 Entomologists with whom he was more or less intimately associated. 

 Chief among these was Dr. H. Loew, with whom he was in constant 

 correspondence for over twenty years, and in whose work he took so large 

 and important a share. This is somewhat painful reading, inasmuch as 

 Loew seems to have been largely affected by selfish motives and jealousy 

 of others, and to have lacked the straightforwardness and candour that 

 might have been looked for in so eminent a man ; at the same time the 

 author closes his account by stating that he is " entitled to a place, not 

 only among the heroes, but also among the martyrs of science." 



The briefer notices of others are very delightful, namely, of Kennicott, 

 Walsh, Bassett, Le Baron and Hagen, among American Entomologists, 

 and of Haliday, VVinnertz, Zeller, Rondani and others of European fame. 

 Portraits are given of Haliday and Loew, and a facsimile of the mar- 

 vellously minute caligraphy of the latter, showing 132 lines of written 

 matter on an ordinary .'^heet of foolsca[) paper 1 



In this " Record of His Life " Baron Osten Sacken has certainly 

 given us a volume of very great interest and also of much historical value. 

 From its pages one learns to apiMCciate more than ever the excellence of 

 the author's scientific work and the unselfish spirit in which he ever 

 devoted himself to it. As he truly says : " The best part of my work is 

 that which has assisted and stimulated the work of others, and I am 

 conscious at the same time that that part of my work is the largest."
