272 ENTOMOLOGICAL NEWS. [Oct., 'o6 



disturbed its normal function and finally culminated in the 

 brain disease to which he succumbed. Every one of us, very 

 probably, is afflicted with some malformation of this kind 

 which more or less impairs his mental vision." May we be 

 as charitable with Osten Sacken in regard to the two or three 

 animosities which he especially cherished. 



As a correspondent, he was delightful. During his Ameri- 

 can residence he accumulated large numbers of letters from 

 entomologists in various parts of the country, which it seems 

 from his Record he faithfully preserved till his death. This 

 material would be of great value if ultimately acquired by 

 some American institution ; the history of American ento- 

 mology during the '5o's, '6o's and 'yo's is largely embalmed 

 therein. 



Two years ago he wrote, " As the Grandfather of American 

 Dipterology, I am very much interested in the progress of my 

 descendants. ' ' 



On another occasion, "At my age a man does well, when 

 he is able to do so, to withdraw from his usual occupation or 

 profession, and to leave the field for a younger generation. 

 For about fifty years I have worked hard in my science and 

 have reason to be content with the result. My Record I hope 

 to have published bye and bye, and shall allow myself from 

 time to time to publish " obiter dicta" on dipterology, like the 

 short articles which have appeared in the Ent. M. M., London, 

 recently. But, with these exceptions, I give up entomology, 

 and shall not take any part in discussions. In many points 

 my opinions are peculiar. I have explained them distinctly 

 enough in my writings, and posterity will pronounce upon 

 them. For this reason I do not enter into any further discus- 

 sion about * * *, the result of which is, for me, of sovereign 

 indifference. ' ' 



And yet again, "My health is excellent, but my brain is 

 easily tired and my working power has much diminished. I 

 am in the position of a traveler at a railway station, waiting 

 for a train to depart with. This departure I expect without 

 the slightest apprehension." 



He was a man, take him for all in all, 

 I shall not look upon his like again.
