OBITUARY. 



We regret to announce the death, on December 21st last, of The 

 Rev. Henry Charles Lang, M.D., Vicar of All Saints, Southend. 



Having studied at King's College, London, he obtained his M.R.C.S. 

 in 1873; three years later L.R.C.P., and L.S.A., and in 1877 the 

 Brussels degree of M.D. Subsequently, however, he entered Holy 

 Orders, being ordained deacon in 1885, and priest in 1886. After 

 holding curacies at Reading, Plymouth, and elsewhere, he was, in 

 1892, nominated to the vicarage of All Saints. 



To entomologists Dr. Lang was well known as an authority on 

 the Butterflies of Europe, and he published a work, in two volumes, 

 upon this subject (1881-84). In June, 1899, he commenced a series 

 of articles, with illustrations, entitled " Butterflies of the Palaearctic 

 Region," in ' Science Gossip ' (New Series). These were continued 

 monthly until publication of that journal ceased in 1902. Dr. Lang 

 was elected a Fellow of the Entomological Society of London in 1900.
