Aristarchus of Samos anticipated the Copernican system by asserting that the sun was the centre of the universe. In 

 the above work he shows the method of estimating the relative distances of the sun and moon from the earth by the 

 angle formed by the two bodies at the observer's eye at that moment when the moon is exactly half-luminous.

' Ouvrage important pour la connaissance de la musique des Grecs, et le plus ancien traite que nous ayons sur cet objet. 

 ... La doctrine musicale d'Aristoxene, opposee a celle de Pythagore, a fait epoque dans 1'antiquite. Rejetant les calculs 

 mathematiques de celui-ci, iln'admettait pour juge que 1'oreille, opinion qui divisa la Grece en deux sectes musicales : celle 

 des pytliagoriens, appeles canonici, et celle des aristoxeniens, appeles harmonici.' Biogr. Gen.

 phenomena, 2 vols. folio, cl. gilt, 18s Qd (p. 1. 10* nett) 1897-9 



Lord Armstrong's immense practical achievements have overlain his reputation as a scientific investigator. ' In 

 later life his happiest hours, when not employed in planting or building, were devoted to electrical research in his 

 laboiatory at Cragside. Among his early experiments with his hydro-electric machine he had shown that a cotton 

 filament in two adjacent glasses travels towards the positive electrode in one, while an encircling tube of water moves 

 towards the negative electrode in the other. This was the startibg-point of his subsequent researches into the nature of 

 the electric discharge. In 1897 he published a beautifully illustrated volume [supra] on ' Electric Movement in Air and 

 Water ', in which he discussed the most remarkable series of figures ever obtained by electric discharge over photo- 

 graphic plates.' //. P. Gurney, pr., D.C.L.
