T HE Committee appointed by the Royal Society to direct the pub- 
lication of the Rhilofophlcal Transactions, take this opportunity to 
acquaint the Public, that it fully appears, as well from the council books 
and journals of the Society, as from repeated declarations which have 
been made in feveral former Tranfaciions, that the printing of them was 
always, from time to time, the Angle act of the refpeciive Secretaries, till 
the Forty-feveuth Volume : the Society, as aBody, never imerefting them- 
ielves any further in their publication, than by occafionally recommending 
the revival of them to fome of their Secretaries, when, from the particular 
circumftances of their affairs, the Tranfadions had happened for any 
length of time to be intermitted. And this feems principally to have 
been done with a view to fatisfy the Public, that their ufual' meetings 
were then continued for the improvement of knowledge, and benefit of 
mankind, the great ends of their Ard inllitution by the P^oyal Charters, 
and which they have ever fmee fteadily purfued. 
But the Society being of late years greatly inlarged, and their com- 
munications more numerous, it was thought advifable, that a Committee 
of their members fhould be appointed to reconfider the papers read be- 
fore them, and feleft out of them fuch, as they fhould judge moft pro- 
per for publication in the future Tranfadions ; which was accordingly 
■done upon the 26th. of March 1752. And the grounds of their choice 
are, and will continue to be, the importance and Angularity of the fub- 
jefts, or the advantageous manner of treating them,; without pretending 
to anfwer for the certainty of the fafis, or propriety of the reafonings, 
contained in the feveral papers fo publiftied, which mull; ft ill reft on the 
credit or judgment of their refpective authors.
