IN MEMORIAM — WILLIAM SIMPSON 
325 
As a field geologist his activities were very noticeable, and his 
many contributions to the literature of geology indicate a wide range 
of research. Another phase of his work was displayed in the classic 
investigation of the Underground Waters of North-west Yorkshire 
{Proc. Yorhs. Geol. Soc, Vol. XIV.), to which he gave aid in 
many ways. His presence on the excursions and field investigations 
of the Society was an incentive of the best kind, as his knowledge was 
wide and his deductions sound. 
After coming to reside at Catteral Hall, Giggleswick, Mr. Gimpson 
took a part in local affairs, and acted as a governor of the Giggleswick 
Grammar School. He died on March 20th, 1915.
