Industries and JVearing Apparel, etc." (8vo., London, 1902); 

 " Subject List of Works o?i General Science, Physics, Sounds 

 Music, Light, Microscopy, and Philosophical Instruftients " (8vo., 

 London, 1903), presented by the Patent Office, London. 



Dr. George Wilson and Mr. H. E. Schmitz, B.A., were 

 nominated auditors of the Society's accounts for the session 

 1902-1903. 



The President referred to the loss sustained by the Society 

 through the death of Sir George Stokes, Bart., who was elected 

 an honorary member of the Society in 1851. The first Wilde 

 Lecture was delivered by Sir George Stokes, and he was also 

 the first recipient of the Wilde Medal. 



Professor Osborne Reynolds, F.R.S., and Professor 

 Horace Lamb, F.R.S,, spoke with reference to the scientific 

 labours of Sir George Stokes. Professor Lamb pointed out that 

 the work of the French mathematicians of the early part of the 

 nineteenth century had been continued by Sir G. Stokes, by 

 whose death there was thus removed a link between the French 

 school of mathematicians and those of the present day. 



Professor Osborne Reynolds, F.R.S., exhibited and 

 explained some models illustrating his mechanical theory of 

 the structure of the universe, propounded in his paper " On the 

 Sub-Mechanics of the Universe," read before the Royal Society. 



Mr. C. E. Stromeyer, M.Inst.CE., read a paper on 

 " Parallax Determinations by Photography," and illus- 

 trated it by a series of lantern slides. 



One of the pairs of slides represented a man's face, the eyes, 

 beard, and other parts alternately disappearing as the one plate 

 was slid over the other. Another pair showed a landscape at 

 Whitby, from which the distances of various objects could be 

 measured by making them disappear ; then followed a pair 

 of stellar photographs, which were of interest as showing how 

 easily the position of even a hazy object, such as a comet, can 

 be determined, and measurements were also made of the path 

 of an electric spark.
