triennially by the Council of the Royal Society of Edinburgh, in 
recognition of original work in Physics, Chemistry, or pure or 
applied Mathematics. Evidence of such work may be afforded 
either by a paper on one of the above subjects, or some discovery 
in them, elsewhere communicated or made, which the Council 
may consider to be deserving of the prize. The prize consists of 
a sum of money, and is open to men of science resident in or 
connected with Scotland. The first award was made in the year 
1887. In accordance with the wish of the donor, the Council of 
the Society may on fit occasions award the prize for work of a 
definite kind to be undertaken during the three succeeding years 
by a scientific man of recognised ability. 
At the close of the first triennial period, 1884-87, the prize 
was awarded to Sir William Thomson, Pres. R.S.E., F.R.S. (Lord 
Kelvin), for a remarkable series of papers on “ Hydrokinetics,” 
especially on waves and vortices, which have been communicated to 
the Society. At the close of the second triennial period, 1887-90, 
it was awarded to Professor P. G. Tait, Sec. R.S.E., for his work 
in connection with the “ Challenger ” Expedition and his other 
researches in Physical Science. At the close of the third triennial 
period, 1890-93, it was awarded to Alexander Buchan, LL.D., 
for his varied, extensive, and extremely important contributions to 
Meteorology, many of which have appeared in the Society’s 
publications. The last triennial award, 1893-96, was made to 
John Aitken, Esq., for his brilliant investigations in Physics, 
especially in connection with the Formation and Condensation of 
Aqueous Vapour. 
The Gunning Fellowship in connection with the Society of 
Antiquaries of Scotland, constituted by the Victoria Jubilee gift 
of His Excellency Dr R. H. Gunning, “to enable experts to visit 
other museums, collections, or materials of archseological science 
at home or abroad, for purposes of special investigation and 
research,” was inaugurated in the Jubilee year, 1887-88, by the 
appointment of Dr Joseph Anderson and Mr George F. Black 
to visit and report on local museums in Scotland. The Report, 
which extends to 160 pages, is printed, with illustrations, in the
