OBITUARY. 



HENRY TAMES SLACK. 

 Born October 23, 1818. Died June 16, 1896. 



WE regret to record the death of this well-known microscopist. 

 Mr. Slack was educated at Dr. Evan's School, Hampstead, 

 was a barrister-at-law, and was proprietor and editor of the Atlas and 

 the Intellectual Observer. He erected an observatory at his residence, 

 Forest Row, Sussex, but paid more attention possibly to the micro- 

 scope, his little book, " The Marvels of Pond Life," of which a third 

 edition appeared in 1878, showing close interest and observation. 

 He was a warm advocate of the Sunday opening of museums; and his 

 attachment to the cause of Liberalism and progress, and his sympathy 

 with Kossuth, Mazzini, and others, is told in a short sketch by Mr. G. 

 J. Holyoake, in the Daily News, June 27, to which sketch we are 

 indebted for the above facts. 



There are also announced the deaths of: W. von Henke, 

 Professor of Anatomy at Tubingen University, on May 17, aged 62 ; 

 F. LuDY, the coleopterist, on March i ; Dr. Hosius, Professor of 

 Mineralogy at Miinster, aged 70 ; and the ethnographer. Von Irgens- 

 Bergh, on May 21, at Copenhagen, aged 76. Botanists have to 

 deplore the loss of: R. P. Delavay, well-known for his researches 

 on the flora of China, who died at Yunnan in that country, on Decem- 

 ber 31, 1895, at the age of 62 ; Dr. G. Liebscher, Professor of 

 Agriculture and a noted investigator of plant-physiology, who died 

 at Gottingen, on May 9, at the early age of .43 ; and Dr. J. Lerch,

 March 13.
