contact with geologists. He directed his attention especially to ac- 

 celerating the processes involved in silicate-analysis ; and, although 

 he was always more interested in doing work than in publishing 

 the results, he was induced to communicate a paper to the Birming- 

 ham Meeting of the British Association in 1886. This paper, on 

 ' An Accurate & Rapid Method of Estimating the Silica in an 

 Igneous Rock,' was published in extenso in the Report of that 

 meeting. 



Mr. Player was ever ready to assist geologists by analysing rocks, 

 and the following papers, published in our Quarterly Journal, con- 

 tain some of the results of his work : — ' On a Phosphatic Chalk 

 with Belemnitella quadrata at Taplow ' J ; 'On the Plutonic Rocks 

 of Grarabal Hill & Meall Breac ' 2 ; 'On the Banded Structure of 

 some Tertiary Gabbros in the Isle of Skye '. 3 



During the last years of his life he interested himself in photo- 

 graphy and perfected a process, known as Playertype, for copying 

 engravings and maps by contact-printing without allowing light to 

 pass through the object to be copied. He died on February 24th, 

 1908. [J. J. H. T.] 



Bennett Hooper Brough (1860-1908). — Bennett Hooper Brough 

 was born at Clapham in 1860 ; he was the eldest son of John 

 Cargill Brough, F.C.S., who was himself a man of considerable 

 literary and scientific ability. He received his early education at 

 the City of London School, and afterwards studied first at the 

 Royal School of Mines, London, and then at the Royal Prussian 

 Mining Academy at Claustal. In 1882 he was appointed Assistant 

 to Sir Warington Smyth, and in 1886 Instructor in Mine-Surveying 

 at the Royal School of Mines ; in 1893 he became Secretary to the 

 Iron and Steel Institute, a post which offered ample opportunity 

 for the exercise of his varied and brilliant endowments. He was 

 particularly successful in organizing the foreign meetings of the 

 Institute, and, in recognition of his services in connexion with the 

 meeting in Stockholm, he was created a Knight of the Order of 

 Wasa by the King of Sweden and Norway. His labours on behalf 

 of the Institute terminated only with his death, which took place 

 after a short illness on October 3rd, 1908.
