land-tracts flnring the Secondary and Tertiary periods respectively, 

 and on the effect upon Animal life which great changes in Geo- 

 graphical configuration have probably produced." It was read 

 before the Geological Society, and was afterwards printed in the 

 Philosophical Magazine. In 1863 he wrote a paper on " The events 

 which produced and terminated the Purbeck and Wealden deposits 

 of England and France," and shortly after, another, on "The Belgian 

 Equivalents of the Upper and Lower Drifts of the Eastern Counties," 

 a third on "The Red Crag and its relation to the Fluvio-Marine 

 Crag and the Drift of the Eastern Counties," and a fourth " Oa 

 the Foi'mation of the River Valleys of the East of England." In 

 tlie last of these he enunciated a theory which has received 

 but little attention, but which he strenuously maintained till the 

 last. He was elected a Fellow of the Geological Society in 1864. 

 Having long studied the Glacial beds of East Anglia, he read 

 a paper, in the same year, embodying the results of the work he 

 had carried on in this field, on "The Drift of the East of England." 

 The next year he published, for private circulation, a map of the 

 drift over eight counties, togetlier with remarks in explanation of 

 it ; the first attempt which had ever been made to map the Glacial 

 beds, and which, constructed at a time when the Geological Sui'vey 

 ignored these deposits altogether, must be regarded as the parent as 

 well as the predecessor of the many glacial maps which have since 

 been issued. He had been designated for the legal profession, 

 having been admitted a solicitor in 1851, but the death of a gentle- 

 man with whom he was associated, in 1865, although leaving a 

 lucrative practice in his hands, gave him an opportunity, which he 

 seized with alacrity, of devoting himself to the elucidation of the 

 Glacial beds. In association with his friend, Mr. Harraer, of 

 Norwich, he spent the following six or seven years in the work, 

 during which time more than 10,000 miles were traversed, and 

 every section of importance in the whole district examined, the 

 results being published by the Paleeontographical Society in 1872. 



Mr. Wood's mental activity and industry were marvellous. 

 Althougli during the last ten years of his life a confirmed invalid, so 

 much so as to be for a great part of the time incapacitated from all 

 bodily exertion, and during the summer months from all kinds of 

 literary or mental work ; papers of the most elaborate kind were 

 constantly issuing from his study. Previously to his health breaking 

 down, he had, in company with the Eev. T. L. Rome and Mr. 

 Harmer, made several excursions into Lincolnshire, Yorkshire, and 

 the neighbouring counties, for the purpose of studying the Glacial 

 deposits of the North-east of England, the result being published 

 by himself and Mr. Rome, in 1867, in the well-known paper on 

 that subject. In 1870 this was supplemented by another elaborate 

 paper, accompanied by what Sir Charles Lyell called " Miles of 

 Sections," "On the Relation of the Boulder-clay without Chalk of 

 the North of England to the Chalky Clay of the South." In 1867 

 he had given to the Society an account of his views on the structure 

 of the Post- Glacial beds of the South-east of England, having
