He early formed a friendship with the late Professor J". Phillips, 

 and accompanied him and Sir H. De la Beche during a part of their 

 work in Devonshire, about 1835. In 1844 he went to Switzerland 

 to renew his acquaintance with Agassiz and study glacial 

 phenomena ; he stayed some days at the Grimsel Hospice in com- 

 pany with Professor Eesor. During the same trip he met Professor 

 J. Forbes on the Mer de Glace, and had the advantage of seeing the 

 results of his observations. 



"We have now to mention his Opus Magnum — what may be almost 

 said to have been the work of a lifetime — viz., his large geological 

 map of the Bristol coalfields. He began a geological map of the 

 environs of Bristol, perhaps about 1835; he seems to have worked 

 originally on large-scale maps, transcripts of parish ones, and, as 

 Sir H. De la Bechc was soon after that time working for the 

 Government Geological Survey in the district, he seems to have 

 copied the boundary lines on the one inch ordnance map and pre- 

 sented his results to the JS'ational Survey. His name appears 

 accordingly on the Bristol sheet of the Government map. His

 his work on the large scale, which admits of much greater accuracy 

 of delineation, but to continue it and publish it. This object he 

 seems to have kept before him, and after more than twenty years of 

 work he finally accomplished it ; the large map of the Bristol 

 coalfields, on a scale of four inches to the mile, was finished in 

 1862. It contains over 720 square miles of country, reaching 

 from Wells on the S., to Berkeley on the JS"., and Bath on the E. ; 

 the geological lines are all from his own surveys, on which he 

 bestowed most scrupulous care, and it maybe truly said that no 

 sicgle amateur has ever produced such a work on his own resources. 

 The topographical basis of the map too had to be reduced by
