" The Century which has elapsed since the recognition of 

 "the great generahsations which led to the establishment of the 

 " Theory has afforded continuous proof of its importance through- 

 " out the whole domain of Physical Science, and especially of 

 "Chemistry, every new development of which has served to 

 "consolidate its position. The Chemical Society offers at the 

 " same time to the Literary and Philosophical Society, so much 

 " older than itself, an expression of hearty congratulations on 

 " having been the medium of the first publication of that Theory 

 "to the world, and having for upwards of a Century so honour- 

 " ably assisted in promoting Scientific, Literary, and Philosophical 

 "enquiry, more especially in those early days before the time of 

 " Dalton when the Physical Sciences were still unorganised and 

 " waiting for the firm and pliilosophical basis on which they 

 " now rest.

The President, in presenting the Wilde Medal for 1903 to 

 Professor F. W. Clarke, and a Dalton Medal (struck in 1864) 

 to Professor Osborne Reynolds, F.R.S., said: — 



" Prof. Clarke, to whom the Wilde Medal is awarded, has 

 "done distinguished work in a very wide field, ranging from 

 " Chemistry and Chemical Physics to the application of Chemistry 

 " to the purposes of the Geological Survey of the United States, 

 " in which he has held a distinguished position for the last twenty- 

 " five years. His paper ' On the Determination of the Melting 

 " Points, Boiling Points, and Specific Gravities of Bodies,' 

 "published in 1873, indicated '■he direction of his researches 

 "which led to his work on 'The Constants of Nature — a 

 " Re-calculation of Atomic Weights,' published by the Smith-
