REPORT OF THE COUNCIL. xvit 
Toronto Colonial Observatory. Mr. Birt has completed the reduction and 
discussion of the series of electrical observations made at Kew; and Mr. 
Ronalds has drawn up a Report describing the modifications and improve- 
ments which he has introduced in the seif-registering apparatus during the 
last year. Both these Reports will be read to Section A. preparatory to a 
consideration of any further recommendation which it may appear desirable 
to make for the continued maintenance of the Observatory. In connexion 
with this subject, the Council have great pleasure in announcing to the 
General Committee, that Her Majesty's Government, on the joint application 
of the Marquis of Northampton and Sir John Herschel, have granted to 
Mr. Ronalds a pecuniary recompense of £250 for the invention of his method 
of constructing self-registering magnetical and meteorological apparatus. It 
will be recollected by many members of the General Committee that the 
subject of self-registering instruments was discussed at the meeting of the 
British Association at Cambridge, in 1845, upon the application for a grant 
of money from the funds of the Association to enable Mr. Ronalds to com- 
plete an apparatus for that purpose at Kew; and that a recommendation 
was made on that occasion by the Association to Government—which recom~ 
mendation was concurred in by the President and Council of the Royal 
Society—of the expediency of encouraging, by specific pecuniary rewards, 
the improvement of self-recording magnetical and meteorological apparatus. 
As the grant to Mr, Ronalds has been made in consequence of that 
original recommendation and the favourable reply that was returned to it, 
and as the apparatus itself has been constructed, and its successful operation 
shown at the Observatory of the Association, of which Mr. Ronalds is the 
Honorary Superintendent, the Council have deemed it proper to make this 
formal, and as they are sure acceptable, announcement of the favourable 
reception which has been given to the application on Mr, Ronalds’s behalf; 
but they are glad, at the same time, to take the opportunity of expressing 
the satisfaction with which they have learned that the ingenious invention of 
Mr. Brooke, for similar purposes, has also received a pecuniary recompense 
from the Government. 
II. The Council regret that they are still unable to announce the publica- 
tion either of Professor Edward Forbes’s Researches in the Aigean Sea, or 
of the Mountjoy Observations, for which purposes grants of public money 
have been sanctioned by Her Majesty’s Government at the recommendation 
of the British Association. 
III. The Council have added the following names to the list of Corre- 
~ sponding Members of the British Association :— 





Professor Pliicker of Bonn. 
Dr. Siljestrom of Stockholm. 
Prof. H. D. Rogers of Philadelphia. 
IV. Prof. Dove, of Berlin, Corresponding Member of the British Asso- 
ciation, having offered to supply the Association with as many copies as 
_ might be desired of his Maps of the Monthly Isothermal Lines of the Globe, 
founded upon the Temperature Tables printed in the volume of the Reports 
of the British Association for 1848, which maps have been partly engraved 
and partly lithographed at the expense of the Royal Academy of Sciences 
at Berlin, the Council directed that Prof. Dove should be requested to supply 
the Association with 500 copies, on the understanding that the Association 
_ should pay for the paper and for taking off the impressions; and that the 
_ copies thus furnished should be sold, under the direction of the officers, to 
_ Members of the Association at cost price, with the translation of a report 
= 1849. c
