116 ANNUAL REPORT OF THE COUNCIL

JOHN ALEXANDER DELL, who died on 8 March 1964,at the age of eighty-two,had been a member of the Geologists' Association since 1943 when, afterretirement, he returned to the south of England. He was born in London,attended the Friends' School at Sidcot, and later studied at the YorkshireCollege and Leeds University, where he took his M.Sc. He was at Leedswhen L. C. Miall in Natural History and P. F. Kendall in Geology wereproviding many new ideas in their subjects. After teaching some years atSidcot and in the south of England from 1912 to 1942 J. A. Dell wasbiology master at Bootham School, York. Here he did much to maintainthe flow of distinguished scientists for which the school is well known. Inaddition to biologists and medical men a number of his former pupils arenow well-known geologists. The subject was never taught for examinationsbut it was always one of the leisure interests fostered by the NaturalHistory Society in the school. York was an excellent centre and there canbe few accessible places in the county where J. A. Dell had not travelledwith parties of boys in the study of Natural History and Geology. Henever failed to appreciate and encourage even the most elementaryobservations in the field, so making leisure-time study of science a realadventure that led in many cases to careers in research and provided others,with spare-time interests of the greatest possible value. His kindly sense ofhumour and his genuine appreciation of the point of view and ideas ofothers, combined with a very wide range of scholarship in many fieldsoutside the sciences, made him an exceptional schoolmaster.

From 1938 to 1943 J. A. Dell was Hon. General Secretary of the York­shire Geological Society. This service involved a great deal of effort, butthe activities of the society were so well maintained during this difficultperiod that in recent years the Yorkshire Geological Society has sharedfully in stimulating the growing public interest in geology in the north ofEngland.

After taking such an active part in the promotion of amateur andprofessional interest in geology in Yorkshire J. A. Dell gained greatpleasure from being able to take part in the meetings of the Geologists'Association in London.

J. A. Dell was author of several publications. He produced two intro­ductory works on biology and a short biography of Arthur Rowntree, whohad been his headmaster from 1913 to 1927. In 1941 he was joint authorwith W. S. Bisat of a short paper, 'The Occurrence of a Bed ContainingMoss in the Boulder Clays of Dimlington' (Proc. Yorks. geol. Soc., 24, 219).
