Sir W. H. White. — By the sudden death, on the 27th 

 February, of Sir William Henry White. K.C.B., Sc.D., LL.D. 

 D.Eng.j F.R.S.j one of the most noted naval architects and engi- 

 neers of our time has passed from the scene. Only a few months 

 ago Sir William had been elected President of the British Asso- 

 ciation for the Advancement of Science, and he was to have 

 presided over the next Annual Session of that Association, which 

 is appointed to lake place in Birmingham during September. 

 I Join in February, 1845, White entered the Royal Dockyard at 

 Devonport as an apprentice at the age of fourteen, and five years 

 later he was the first student to be enrolled in the Royal School 

 of Naval Architecture at South Kensington. In 1870 Mr. White 

 joined the Constructive Department of the Admiralty, in which 

 he had risen to the position of Chief Constructor at the time 

 when he left the Department in order to associate himself with 

 the great engineering firm of \\ . ( i. Armstrong & Co. During 

 this period of his connection with the Admiralty (1870-1883), 

 White had taken a prominent part in the new designs, whereof 

 II. .M.S. Inflexible, with her two turrets en echelon, each provided 

 with two 16 in. (81 ton) guns, was the embodiment. Sir Edward 

 Reed, who had retired from the post of Chief Constructor to 

 the Navy in 1870. led a strong opposition against these designs, 

 but a specially qualified committee was appointed to report on 

 them, and, after long and exhaustive practical trials, this com- 

 mittee reported that the design fully satisfied all that the condi- 

 tions expected of it. The Inflexible, which wa> the first ship in 

 the British Navy to carry compound armour, took a prominent 

 part in the bombardment of Alexandria (1882), and was then 

 the most recent ironclad in the Meet. Subsequent developments 

 of this design were represented by 1I.M.SS. Ajax, Agamemnon, 

 Colossus, and Edinburgh, and in the construction of the hulls of 

 the last two battleships Sir William first superseded iron by steel. 

 In 1885, the Director of Naval Construction, Sir Nathaniel 

 Barnaby, having resigned. White rejoined the Admiralty as his 

 successor, and remained Director until 1902. The Lusitania and 

 Mauretania were amongst the steamships with whose design and 

 construction he was associated in later years. Sir William White 

 presided over the Royal Society of Arts in 1908 and 1909. In 

 1903 he was President of the Institution of Civil Engineers. Of 

 the Institution of Mechanical Engineers he had also been Presi- 

 dent. In 1877 he first joined the Council of the Institution of 

 Naval Architects, becoming Vice-President in 1886. Pie was 

 also connected with the Imperial College of Science and Tech- 

 nology, and with the National Physical Laboratory.
