1860-70] ROYAL ASTRONOMICAL SOCIETY 
Two years later we learn, with the proceeds of the sale of one of 
two copies he had made at Florence of a portrait of Galileo, he 
procured a small telescope of about two inches aperture. With 
the help of the Berlin Star Charts he discovered his first small 
planet in 1852, and Arago named it Lutetia. With slightly 
increased telescopic power, in the next nine years he had discovered 
twelve or thirteen more. He was elected an Associate in 1866, 
and died only a few months later at Fontainebleau. 
The rapid increase in the number of discoveries of minor 
planets led to an agreement in 1863 between the Observatories 
of Greenwich and Paris for a distribution of the labour of the 
meridional observations of these small bodies. The agreement 
took a peculiar form, which was determined by the obligation of 
the Royal Observatory to maintain meridional observations of 
the moon, a matter which had always been of high importance 
in the responsibilities of Greenwich. Airy and Le Verrier arranged 
to divide the additional labour of observations of the planets, 
by the agreement that the Observatory of Paris should undertake 
them from full moon to new moon, the Observatory of Greenwich 
remaining charged with those from new moon to full moon. Then 
was inaugurated what has been claimed as the first specific plan of 
co-operation among astronomers. In the following year the 
Director of the National Observatory, Washington, also promised 
to co-operate in the observations. 
Early in 1861 the Treasurer, Whitbread, had called the atten 
tion of the Council to the fact that the yearly expenditure had 
exceeded the annual income by over £200. A Committee was 
appointed at once to examine into the general subject of the in 
come and expenditure of the Society. They proceeded in the most 
business-like fashion to their task, and drew up a valuable report. 
It appeared from it that the average expenditure of the preceding 
four years had been about £60 in excess of the average income, 
which was increasing only at the rate of about £18 a year. The 
adverse balances were ascribed as principally due to the growth of 
the bills for printing. With respect to the treatment of com 
pounders’ fees, the Committee pointed out that :— 
By a minute of Council, March 1820, it was resolved that 
all compositions should be funded, and the interest of the fund 
alone treated as income. 
By the minute of June 1828, it was recommended that on the 
decease of any compounder his composition should, if needful, be 
made available for general purposes, but that the permanent fund 
should never be reduced below an amount equal to the product of 
£21 by the number of surviving compounders.
