The following address, by David Grieve, Esq., the retiring 

 President, was then delivered : * 



Gentlemen, — In opening to-night the one hundred and 

 seventh session of this Society, I may be permitted to say 

 that it is also the fiftieth year of my connection with it, 

 during which long period I have seen it under various phases 

 of prosperity and adversity. I do not know of any older 

 living member than myself, and thus cannot help looking 

 upon this Society with somewhat paternal tenderness. Such 

 being my position, I am strongly tempted to touch a little on 

 its past history ; but having already pretty fully exhausted 

 this subject in a letter written to my friend Dr M'Bain, and 

 published not long ago in the Society's Transactions, I shall 

 not at present trespass on your time in regard thereto, further 

 than to observe that the Eoyal Physical Society has done 

 good service in its day to science, and has numbered amongst 

 its Fellows many of the most distinguished scientists of our 

 country. 



Before proceeding with some very general remarks, I have 

 an obituarial duty to perform. It is usual for the President 

 to notice in his address such prominent members who may 

 have died during the recess. On the present occasion two 

 names only occur to me as having departed since we last 

 met; these names are, Mr George Logan, Writer to the 

 Signet, and Dr James Bryce, F.G.S. 



Mr Logan held an important office in the General Ptegister 

 House of this city. In his earlier life ho was a well-known 

 legal practitioner of Edinburgh, and took a very active part 

 in general politics on the Liberal side. Some years after- 

 wards, and when he had entered upon the legal office to 

 which he had been appointed, having then more leisure, he 

 gave himself more to the cultivation of science. He joined 

 this Society, I believe, about the year 1848, and subsequently 



* Since the delivery of this address it has been considerably curtailed by 

 the author for the sake of brevity.
