The sudden death of John Hopkinson on July 5th last, in hi& 

 74th year, has deprived us of a worker whose activities were 

 beneficial in many branches of science besides our own. Born at 

 Leeds in 1844, Hopkinson came while young to reside in Hertford- 

 shire, first at St. Albans and later at "Watford. Engaged in 

 business during the greater part of his life, as a member of the 

 well-known firm of piano-manufacturers, he devoted the whole of 

 his leisure to scientific pursuits, and was a prominent example 

 of the amateur worker to whom British science owes so much and 

 for whom it has always been distinguished. Zealous in the study 

 of Nature in all its aspects, he did excellent work as an original 

 observer, and was, besides, ever ready to bring his practical training 

 to bear upon the promotion and welfare of the scientific associations 

 which have rendered indispensable service in the spread and advance- 

 ment of knowledge. He was the organizer and staunch supporter 

 of the Hertfordshire Natural History Society (1875) and of the 

 Conference of Delegates connected with the British Association 

 (1880), serving both bodies in varied capacities. He took a 

 prominent part in founding the County Museum for Hertfordshire 

 at St. Albans. He was active in the Ray Society, being its Treasurer 

 from 1899 to 1902, and its Secretary from that time until his 

 death. His Fellowship in our own Society was of 50 years' 

 standing (he was elected in 1869), and he served on our Council 

 from 1884 to 1888. He Avas likewise a Fellow of the Linnean, 

 Zoological, Microscopical, and Meteorological Societies, and an 

 Associate of the Institute of Civil Engineers. 



Hopkinson was one of the pioneers of the study of graptolites 

 and their zonal distribution. He was joint author with Prof. C. 

 Lapworth of an important paper on the Graptolites of the Arenig
