study of matters relating to water-supply, rainfall, and percolation 

 and evaporation. E'.iin gauges and percolation gauges had been 

 installed at Nash Mills by his uncle, John Dickinson, and for a long 

 series of years they were under the personal supervision of Sir 

 John E vans. Water-supply led naturally to practical geology, and in 

 that field Evans was a leading authority, but it was from his studies 

 in what may be termed antiquarian geology that he was best known 

 to the general public and to geologists both at home and abroad. 

 It was largely owing to the work of Evans in conjunction with 

 Sir Joseph Prestwich, that the great age of the implements found 

 in the terraces of Eiver Gravel of the Somme and the Thames was 

 satisfactorily established. 



T'le collection and study of coins attracted Evans's enthusiastic 

 attention from early days, and in the end he was one of the leading 

 numismatists of Europe. 



Sir John Evans was elected into the Eoyal Society in 1864. In 

 ] 87S he became the Treasurer and he held that important post for 

 twenty years. In 1884, when Huxley, who was President, was 

 away ill, Evans prepared and delivered the Anniversary Address. 

 He constantly held office in the Geological Society and was 

 President in 1874-76. In 1880 he received the Lyell Medal, and 

 tbe Prestwich Medal was presented to Lady Evans last February 

 in memoi'iam. 



Evans was at different times President of the Society of Anti- 

 quaries, the Eoyal Numismatic Society, the British Association, 

 and of many otlaer societies. He was made K.C.B. in 1892. 



He was the author of ' The Ancient Stone Implements, 

 Weapons, and Ornaments of Gi'eat Britain,' which first appeared 

 in 1872, and a second edition in 1897 ; ' Ancient Bronze Imple- 

 ments, Weapons, and Ornaments of Great Britain and Ireland,' 

 ISSl ; ' The Coins of the Ancient Britons,' 1864 ; and of numerous 

 papers which appeared in different serial publications. 



Sir John Evans was married three times. His first wife was a 

 daughter of his uncle, John Dickinson, and at her death she left 

 three sous and two daughtei's. One of the sons is the well-known 

 explorer of Knossos and a Fellow of the Eoyal Society. Tiie 

 second wife, a daughter of Mr. Joseph Phelps, left no children. 

 Lady Evans, who survives her husband, is the daughter of 

 Mr. Charles C. Lathbury and has a daughter. Lady Evans is an 

 accomplished classical scholar aud antiquary. 



Sir John Evans was elected a Fellow of the Linnean Society on 

 March 21st, 1878, and died at his residence, Britwell, Hertford- 

 shire, on May 31st, 1908. [H. W. Monckion.]
