ADVERTISE MEN T. 
T Ii E Committee appointed by the Royal Society to direct the pub- 
lication of the Philofopbical .Tranfadio?is, take this opportunity to 
acquaint rite Public, that it fully appears, as well from the council-books 
unci journals of the Society, as from repeated declarations, which have 
been made in feveral former ~Tv an f actions ^ that the printing of them was 
always, trom time to time, the lingle act of the refpcctive Secretaries, till 
the Eorty-fevcnth Volume: the Society, as a body, never intereflingthem- 
fcl ves any further in their publication, than by occallonally recommending 
th e revival of them to fomeof their Secretaries, when, from the particular 
circumfhmccs of their affairs, the Tranjaclhns had happened for any 
length of time to be intermitted. And this feems principally to have 
been done with a view to iatisrV the Public, that their ulual meetings 
were then continued for the improvement of knowledge, and benefit of 
mankind, the great ends of their firft iuhitution by the Royal Charters, 
and which they have ever iince flcadily purified. 
But the Society being of late years greatly inlarged, and their corr- 
munications more numerous, it was thought ad vifeable, that a Committee 
ol their members fhould be appointed to reconfider the papers read be* 
fore them, and felcft out of them fach, as they fhould judge molt pro- 
per for publication in the future Tra/facTtidns ; which was accordingly 
done upon the 26th of March 1752. And the grounds of their choice 
arc, and will continue to be, the importance and lingularitv ot the fub- 
jefts, or the advantageous manner of treating them * without pretending 
to anlwer for the certainty of the fa els, or propriety of the rcafonings, 
'contained in thelevoral papers lo publilhed, which mult Itill reft on the 
cadk or judgment of their iclpeffivc authors.
