I may here add that our volumes of Transactions are rapidly 
exhibiting an increase in the number,—I hope also in the value of 
their contents. About-ten or twelve years ago, one year’s Transac¬ 
tions did not exceed 100 quarto pages. During the three years 
which followed, their average size was measured by 250 pages; 
during the last three years by 310 pages. 
The Society is aware that we have three prizes in our gift, created 
by members of our body at different periods,—the Neill prize, the 
Keith prize, and the Brisbane prize. A period of two years 
elapses, in the case of the two latter, before bestowal. Last year 
the Keith prize was awarded, consisting of a gold medal and £50, 
“ for the best communication on a scientific subject.” It was 
awarded to Professor Tait, for a paper, published in our Transac¬ 
tions, on the “Rotation of a Rigid Body about a fixed point.”
