PROCEEDINGS OF THE GEOLOGICAL SOCIETY. 



the prize-farm district around Oxford in 1870, of the geology of 

 Belgium, and of Sweden and Norway. In his report upon Denmark 

 he pointed out how each of the geological formations in that country 

 is characterized by a distinctive system of agriculture." 



llr. Jenkins was elected a Fellow of this Society in 1863, and, in 

 spite of ever multiplying and distracting occupations, he always 

 look the warmest interest in our affairs. To the trying disease 

 against which he had struggled so manfully, he at last fell a victim, 

 passing away last Christmas eve at the early age of 45. Few men 

 have accomplished so much work in so short a time and under such 

 adverse conditions. At his open grave the prince who presided over 

 the great Society which he served so faithfully, and the farmers and 

 peasants whose interests he had spent so large a share of his life in 

 promoting, were alike represented ; but among those who mourned 

 his loss there were none who felt it more keenly than his early 

 friends and fellow-workers of the Geological Society. 



Dr. Harvey Buchanan Holl was born at Worcester on the 28th 

 of September, 1820, and received his early education in that town 

 and at Birmingham. When only 17 years of age he met Sir Henry 

 De la Beche, whom he accompanied for six months while engaged 

 in his important studies of the geology of Cornwall and Devon. De 

 la Beche seems to have formed such a high opinion of the abilities 

 of the young geologist that he recommended him to the notice of 

 Professor Eogers, and the result was that young Holl found employ- 

 ment for three years on the Geological Survey of Penns}dvania, 

 afterwards travelling for a year in the United States on his own 

 account. From the pupil of such masters as De la Beche and 

 llogers good services to geological science might be looked for ; nor 

 was the expectation disappointed. After returning to England and 

 taking his medical degree, Dr. Holl accompanied the British Army 

 to the Crimea, remaining there till the end of the campaign. For 

 some time after his return he practised his profession in London ; 

 but in 1862 he retired to llalvern, and in the same year became a 

 Fellow of this Society. It was then that he found time for the 

 c arrying out of his valuable studies on the geology of the Malvern 

 Hills. In opposition to Murchison's views, he maintained the non- 

 intrusive character and the Archaean age of these rocks, constituting 

 himself a pioneer in the study of those isolated portions of the pre- 

 Cambrian floor of Britain which have been uncovered by denudation, 

 and which, during recent years, have attracted so large a share of 

 the attention of geologists.
