Charles Alexander McMahon, 



Lieut. -General. Formerly Commissioner of the Amritsar 

 Division, Punjab. President of the Geologists' Association and 

 Vice-President of the Geological Society of London. Dis- 

 tinguished for his acquaintance with the sciences of Petrology 

 and Geology. He was the first to demonstrate (discover), by 

 study in the field, and with the microscope, the truly granitic 

 origin of the " Granitoid Gneiss " of the N.W. Himalaya, 

 thereby affording a conceivable interpretation of the mountain 

 structure. See his numerous papers (23) in the " Records of 

 the Geological Survey of India" (1876-87). Later, General 

 McMahon has contributed much to the elucidation of the 

 structure and origin of crystalline rocks and rock-making 

 minerals, notably in his papers " On the Rocks of the Lizard " 

 {Quart. Journ. Geol. Soc, vol. xlv., 1889, and, conjointly with 

 Prof. Bonney, in vol. xlvii., 1891); " On the Dartmoor Granite 

 and its Relation to the Surrounding Rocks" {ibid., vol. xlix. , 

 1893); " On Micro-chemical Analysis of Rock -making Minerals" 

 {Alitt. Mag., vol. X., p. 79) ; and "On Optical Characters of 

 the Globules and Spherulites of Lithium Phosphate," &c. 

 {ibid., p. 229) ; and numerous minor papers in the Geological 

 Magazine and the Proceedings of the Geologists' Association.

Hon. Charles Algernon Parson.s, 



M.A. (Camb.). Engineer. M.Inst.C.E. Eminently distinguished 

 as an inventor and engineer. By his invention of the con>- 

 pound steam turbine he has made it practicable to use steam 

 economically in an engine without reciprocating parts. He has 

 adapted the steam turbine successfully to dynamo driving and 

 other uses, and his recent application of it to marine propulsioii 

 is a new departure of particular interest. In developing his 

 inventions he has shown much scientific knowledge and experi- 

 mental skill. Author of a number of papers on the steant 

 turbine, its theory and its applications, in Proc. Inst. Meek. 

 Eng., 1888 ; Trans, of the North-East Coast Inst, of Engineers 

 and Shipbuilders, 1887 ; Inst, of Civil Engineers, Conference, 

 1897 ; Trans. Inst. Naval Architects, 1887 ; Inst, of Marine

 of high-speed screw propellers (Trans. Inst. Nav. Arch., April 

 1897); also the " Behaviour of Carbon at High Temperatures 

 and under Great Pressures" (Proc. Roy. Soc, Phil. Mag.^ 

 September 1893).
