60 OBITUARY NOTICES. Society of Arts in 1897 awarded him the Albert Medal "for services he rendered to the United Kingdom by affording to engineers engaged in the water supply and the sewage of towns a trustworthy basis for their work by establishing and carrying ou during nearly 40 years systematic observations (now at over 3,000 stations) of the rainfall of the British Isles, and by record- ing, tabulating, and graphically indicating the results of these observations in the annual volumes published by himself." In 1891 he was made a Chevalier of the Legion of Honour. His energy in the pursuit of physical truths and his capacity for organizing and retaining the services of his helpers, as well as of stimulating the interest of beginners in his favourite studies, were combined with great kindliness of disposition and unaffected reticence. By none will he be more regretted than by the rank and file of his small army of 3,000 observers. Mr. Symons married in 1866 Miss Elizabeth Luke, who helped him very considerably in his clerical work. The only child of the marriage died in infancy, and Mrs. Symons died in 1884. His death took place on Saturday afternoon, March 10th, 1900, at his house in Camden Square, after an illness of little over three weeks. Although suffering somewhat from overwork he appeared to be in a fair state of health until February 14th, when he was seized with paralysis, from which he never rallied. He was buried in Kensal Green Cemetery on March 16th, after a Memorial Service had taken place at Holy Trinity Church, Marylebone, at which a large number of friends, and many eminent representatives of science were present, including Lord Lister, the President of the Royal Society. A Committee was formed in June, 1900, to establish a memorial to Mr. Symons, in the form of a Gold Medal to be awarded from time to time by the Council of the Royal Meteorological Society for distinguished work in con- nection with meteorological science. We understand that this object has been attained and a sum of about £750 collected. THE LATE MR TOM HAY WILSON. Readers of the Essex Naturalist will regret to hear of the death of Mr. T. Hay Wilson, in his 60th year, on May 10th, 1900, at Bushey Herts. A native of Newcastle-on-Tyne, and long a resident there, he settled in the London district more than twenty years ago. He was for many years connected with, and latterly a member of, the firm of Crossley Bros., the manufacturers of the Otto gas engine. He became a member of the Geologists' Association in 1881, and contributed to Proc. Geol. Assoc, vol, xi., p. 194 (1889), a short paper entitled "Notes on the artificial unmaking of Flints." In this paper he gives his experience of "the behaviour of Flint Shingle when exposed to the action of hot gases, and the following destructive agents: percussion, attrition, heat, with pressure, moisture, and acid." The gases are those discharged from the cylinder of a gas engine. They are driven through a chamber filled with shingle; the gases entering at the bottom of the chamber and escaping quietly through a ventilating pipe at the
