384 Obituary—John Francis Watker, M.A., ete. 
communication with that eminent paleontologist. Of his extensive 
collections, that of Brachiopoda was perhaps one of the best in the 
world. His kindness was proverbial, and he was ever ready, by the gift of 
specimens and the Joan of literature, to assist anyone who was working 
at his favourite subject, and often took much trouble and expense to 
meet the requirements of his many friends and correspondents. At the 
time of his death Mr. Walker had been a Fellow of the Geological 
Society for forty years. His latest piece of Brachiopod work, upon 
which, indeed, he was elaborating at the time of his death, related 
to the Fullers’ Earth Brachiopoda, more especially to those from the 
Bath—Doulting district, and was to have been a joint communication 
with the writer to the Geological Society.” ? 
He leaves a widow and one son, Mr. Gelson Walker, to deplore 
his loss.
