any one, who knows the nature of scientific researches, and the differ- 
ence between the result of money expended in experiments by a good 
and a bad philosopher, to doubt that this sum has produced effects which 
many times the sum applied without the same advantages could not 
have obtained. Without the encouragement of the Association, these 
researches would never have been undertaken: without the aid of such 
men as have frequented the meetings of the Association, they would 
have been attempted to no purpose. It has been said of certain og 
of Europe that they afford— 
Iron and men, the soldier and the sword ; 
in like manner we may say of this Association, that it has supplied at 
the same time the 11 soldier and the weapons with which he 
gains his victories over nature. 
“ But further, besides the expenditure of its own funds, the Associa- 
tion has been the means of procuring the appropriation of very large 
sums to scientific purposes from the national resources. At the sug- 
gestion or request of their body, the reduction of the observations of the 
planets made at Greenwich from the time of Bradley has been comple- 
ted; and the reduction of the observations of the moon has been begun. 
Up to the present time, about 2,200/. has been expended i in all. And 
by a letter from the Astronomer Royal, received since I came here, I 
am informed, that within a few weeks the Government expressed great 
willingness. to advance more money for this purpose; and Mr. Airy 
adds, that next Monday he is to have twelve calculators employed upon 
the work. We have applied to the Government for the extension of the 
ordnance survey into Scotland, and have received a favorable answer. 
We haye tendered our advice that the ordnance survey of England shall 
in future be conducted on a scale of six inches to a mile instead of two 
inches, and this advice is already acted on in the northern counties of 
England, where the eekig « is now proceeding,
