Linnean Society the first part of an elaborate 

 Memoir on the development of Ephemera. 



A paper on two very remarkable swimming 

 (Hymenoptera) insects.

In the autumn he went with Mrs. Lubbock 

 and Miss Arbuthnot, afterwards Mrs. Brandreth, 

 to Denmark and Scandinavia. Mrs. Lubbock 

 wrote for Mr. Galton's Vacation Tourists an 

 interesting account of their visit to the Danish 

 Shell-mounds. 



In Scandinavia they visited Copenhagen, 

 Gothenburg, Stockholm, Upsala (where they 

 were very kindly welcomed and were given 

 mead in a horn on the tumulus of Odin), 

 Christiania, the Dovrefield, Trondhjem, Bergen 

 and the Fillefield. He was amused at a story 

 told by Steenstrup to show that if foreigners 

 were often ignorant of English ways, we also 

 sometimes made mistakes. He said that an 

 Englishman wishing to write to him took the 

 address from a Memoir which happened to be 

 illustrated " with a map and a plate " — in 

 Danish " med en kort og en tavle " ; so he 

 addressed his letter : 



J. Steenstrup, 



Prof. Zoologia, 



Med en kort og en tavle, 



Copenhagen. 



The following letter of this year's date is
