1920] General Monthly Meeting 235 



Resolved, That the Managers of the Royal Institution of Great Britain 

 desire to place on record their sense of the loss the Royal Institution has 

 sustained by the death of John Perry, LL.D. D.Sc. F.R.S., Past President 

 of the Institution of Electrical Engineers and of the Physical Society, 

 General Treasurer of the British Association, Author of " Spinning Tops," 

 '• Calculus for Engineers," " Applied Mechanics," and " The Steam Engine." 



Professor Perry was a brilliant engineer and mathematician. From 1875 

 to 1879 he was Professor of Engineering in Japan, and was among those who 

 introduced modern science to that country. In collaboration with Ayrton he 

 communicated a large number of important memoirs to various scientific 

 societies. 



In 1881 he became Professor of Engineering and Mathematics at the City 

 and Guilds of London Technical College, and held this office until 1896, when 

 he was appointed Professor of Mechanics and Mathematics in the Royal 

 College of Science. During the time o f his appointment as Examiner in 

 Mathematics to the Science and Art Department he took especial interest in 

 improved educational methods, with beneficial results. He was also elected a 

 Member of the Royal Institution in 1906. 



The Managers desire to convey to the family the expression of their 

 sincere sympathy with them in their bereavement. 



The Special Thanks of the Members were returned to Miss Groves 

 and Mr. Thorne for the valuable and interesting gift of Chemical 

 Specimens belonging to the late Professor C. E. Groves ; also to 

 Dr. Thomas W. Dewar, M.R.I., for his Donation of £20 to the 

 Fund for the Promotion of Experimental Research at Low Tem- 

 peratures. J
