Vol. 50.] ANNIVERSARY ADDRESS OF THE PRESIDENT. 43 



years he was head master of tho Clapham Grammar School, and in. 

 1870 was elected to the Savilian Chair at Oxford. His contributions 

 to astronomical science are well known, and in 1886 he was awarded 

 the gold medal of the Royal Astronomical Society for his Uranometria 

 Nova Oxoniensis. He became a Fellow of this Society in 1852, but 

 does not appear to have contributed papers or taken any active part 

 in its work. Dr. Pritchard died at his house in Oxford on the 28th 

 May, 1893, in his 84th year. 



Thomas Hawksley, F.R.S., M.Inst.C.E., was born in 1807 at 

 Nottingham, for which town he was appointed to construct water- 

 works about the year 1830. Subsequently he became so famous in 

 this line of business that he is said to have constructed above one 

 hundred and fifty, many of them large undertakings. To his 

 ingenuity we owe the system of ' constant service ' water-supply. 

 He also rendered great help to Sir Joseph Bazalgette in connexion 

 with the main drainage of London, and gave on more than one 

 occasion important evidence with reference to the water-supply 

 of the metropolis. Mr. Hawksley was elected a Fellow of this 

 Society in 1870, though he never contributed a paper or took any 

 active part in our Proceedings. Yet it may well be supposed that 

 he frequently encountered questions essentially geological, when 

 deciding on the sites of storage-reservoirs, and especially in deter- 

 mining how deep to carry the puddle-walls below the valley-bottom. 

 In such cases he usually availed himself of the advice of skilled 

 geologists, and, as a result of the sinking of trial-shafts, was some- 

 times able to detect slight errors in the published maps, which he 

 was always ready to notify to the proper quarter. 



Mr. Hawksley, who was President of the Institute of Civil 

 Engineers in 1872-1873, must ever be regarded as one of the most 

 eminent engineers of this country. He died in London on the 23rd 

 September, 1893, at the age of 86. 



Edward Bouverie Lttxmoore, M.A., was born about 1829 at 

 Marchwiel, in Denbighshire, and was educated at Eton and Trinity 

 College, Cambridge. For many years he resided at Bryn Asaph, 

 near St. Asaph, and was a Justice of the Peace for Flintshire. 



Although Mr. Luxmoore does not appear to have written any- 

 thing on geology himself, he took a great interest in the science. 

 His hospitable mansion was well known to geologists visiting the 

 neighbourhood, and he was well informed on the geology of
