OBITUARY. 



We regret to announce that Mr. Clarence Fry died suddenly on 

 the golf links at Northwood, near Watford, on April 10th last. It may 

 be said that indirectly we were largely indebted to Mr. Fry for our 

 present knowledge of the insect fauna of the Hebrides, Shetlauds, &c., 

 as he at one time liberally supported professional collectors in their 

 expeditions to these remote portions of the kingdom, and so fostered 

 an interest which subsequently became more fully developed. His 

 collection of British Lepidoptera, which comprised many local and 

 rare species, was disposed of at Stevens's, March, 1896 (Entom. xxix. 

 164). Deceased was the well-known photographer of Kensington. 

 He was about fifty-seven years of age.
