ROYAL MEDALS 
HER MAJESTY QUEEN VICTORIA, in restoring' the Foundation of 
the Royal Medals, has been graciously pleased to approve the following 
regulations for the award of them : 
That the Royal Medals be given for such papers only as have been presented to 
the Royal Society, and inserted in their Transactions. 
That the triennial Cycle of subjects be the same as that hitherto in operation : viz. 
1. Astronomy; Physiology, including the Natural History of Organized Beings. 
2. Physics ; Geology or Mineralogy. 
3. Mathematics ; Chemistry. 
That, in case no paper, coming within these stipulations, should be considered 
deserving of the Royal Medal, in any given year, the Council have the power of 
awarding such Medal to the author of any other paper on either of the several sub- 
jects forming the Cycle, that may have been presented to the Society and inserted 
in their Transactions ; preference being given to the subjects of the year immediately 
preceding : the award being, in such case, subject to the approbation of Her Majesty. 
The Council propose to give one of the Royal Medals in the year 1849 for the 
most important paper in Physics, communicated to the Royal Society after the 
termination of the Session in June 1845, and prior to the termination of the Session 
in June 1848, and printed in the Philosophical Transactions. 
The Council propose also to give one of the Royal Medals in the year 1849 for 
the most important paper in Geology or Mineralogy, communicated to the Royal 
Society after the termination of the Session in June 1845, and prior to the termination 
of the Session in June 1848, and printed in the Philosophical Transactions.
