OBITUARY. 



MISS E. J. KEI,SAI,I,. 



It is with deep regret that we record the death of Miss Kelsall which 

 took place on June 28th, at her residence, Blackrock, Co. Dublin. The 

 deceased lady was the daughter of the late Colonel Kelsall, and was born 

 in 1832. She was one of the original members of the Dublin Naturalists' 

 Field Club, and up to the time of her last illness, she continued to take 

 a deep and active interest in the welfare of that Society. For many years 

 she served on the Committee, and she was most regular in her attendance 

 at the meetings and excursions of the Club. Miss Kelsall was a good 

 field botanist and an ardent horticulturist; she observed closely the 

 animals frequenting her garden, and among the worms found by her 

 was a planarian which has been pronounced new to science by the 

 highest continental authority on the group. Her loss is mourned by a 

 wide circle of friends, and not least by the members of the Dublin Field 

 Club whose interests she had so much at heart. 



Vl^II^i,IAM ARCHER, F.R.S. 



As we go to press we are grieved to learn the death of the late librarian 

 of the National Library, one of the most eminent of Irish men of science. 

 We hope to publish next month an account of Mr. Archer's work by his 

 lifelong friend. Dr. W. Frazer.
