Clement Reid, F.R.S., F.L.S., F.G.S., 
1853—1919. 
Yorkshire geologists are deeply indebted to the late Clement Reid 
for his careful and calm consideration of the Geology of part of their 
county. He joined the Geological Survey in 1874, and had experience 
in many parts of the country, including the moorlands of North 
Yorkshire, before proceeding to Holderness. As long ago as 1885, he 
produced his classical Memoir on the Geology of Holderness," in 
which his extensive knowledge in many directions was demonstrated, 
and that work has proved the basis of all subsequent investigations in 
the area. Not only did Clement Reid make a careful geological survey 
of this interesting district and interpret many of the then complex 
geological problems, but he brought much historical information — 
from documents, old charts, maps and plans — to bear upon the illus- 
tration of the changes due to Coast Erosion and the accumulation of 
new land. His knowledge of Conchology and Botany enabled him to 
elucidate the puzzles which presented themselves in the various 
lacustrine beds in the district, and the geological information he 
gleaned as a result of study of the plant-remains, especially the seeds, 
obtained from the Holderness beds, led him, in later years, to specialize 
in this particular line of research, so that he came to be looked upon 
as the greatest authority on the subject, a position justified by his 
books on " Submerged Forests," and " The Origin of the British 
Flora." In much of this work he was assisted by his wife, formerly 
Miss E. M. Wynne Edwards, B.Sc, and it is pleasant to think that 
Mrs. Reid is still carrying on valuable investigations on the same lines 
as had been set out by her husband. 
Clement Reid was the author of a number of other memoirs 
issued by the Geological Survey, though his first, which dealt with 
Cromer (1882) and that on Holderness, are among his best. The list 
following, which has been kindly copied by the Librarian from the 
catalogue of his works in the Library of the Geological Society of 
London, may not be complete, but it can be taken as representative. 
Clement Reid was of a quiet and unassuming nature, a conscientious 
worker, but rarely entered into discussion or dispute ; consequently 
he did not come before the geological world quite so prominently as
