By the death of Air. John Hopkinson English geologists have lost an 



excellent fellow-worker, and many of them (like the writer) a valued 



friend. 



Born at Leeds in 1844 John Hopkinson came south while still 

 young, residing, with his family, for the greater part of his life in 

 Hertfordshire, first at St. Albans, and afterwards at " Weetwood ",. 

 near Watford, the home of his grandfather. 



Although engaged in business in London 1 John Hopkinson 

 possessed a keen interest in every branch of natural science, and gave 

 all his leisure to their study and advancement, devoting himself more 

 particularly to the pursuit of geology, palaeontology, microzoology, 

 and meteorology. 



His love of open-air studies led him to associate with the members 

 of various field-naturalists clubs, and his training and education in 

 early life well fitted him for the management of their affairs, and 

 he speedily became interested in the promotion and welfare of these 

 societies which have done so much in the past fifty years to nourish 

 the pursuit of science in this country. 



In conjunction with the late Dr. A. Brett he founded the Hert- 

 fordshire Natural History Society in 1875, and served it in various 

 capacities up to the time of his death, being President in 1891-3. 

 It was while residing in St. Albans that John Hopkinson took a 

 prominent part in founding the Herts County Museum, where, at his 

 own expense, he provided the instruments and equipment for the 

 Meteorological Station. It was mainly on his initiation that "the 

 Conference of Delegates " at the British Association was founded in 

 1880, and he served as its Chairman in that year and as its President 

 in 1917. 2 He did much valuable work for the Ray Society, being 

 its Treasurer from 1899 to 1902, and its Secretary since that time. 

 He published in 1913 a Bibliography of the Tunicata, and was part 

 author with J. Cash and Gr. H. Wailes of a monograph on British 



1 As a partner in the well-known firm of J. & J. Hopkinson, piano manu- 

 facturers, retiring only a few years ago on the business being converted into 

 a limited liability company. 



2 An abstract of his address (presented on July 6, 1917) was given in the 

 Geological Magazine for that year, pp. 371-4.
