fhould judge mod proper for publication in the future 
Tranfaftions 3 which was accordingly done upon the 
26th of March 1752. And the grounds of their choice 
are, and will continue to be, the importance or fingu- 
larity of the fubjedts, or the advantageous manner of 
treating them 3 without pretending to anfwer for the 
certainty of the fadls, or propriety of the reafonings, 
contained in the feveral papers fo published, which 
mult ft ill reft on the credit or judgment of their re- 
fpedtive authors. 
It is likewife neceffary on this occafion to remark, 
that it is an eftablifhed rule of the Society, to which 
they will always adhere, never to give their opinion, 
as a body, upon any fubjedt, either of nature or art, 
that comes before them. And therefore the thanks, 
which are frequently propofed from the chair, to be 
given to the authors of luch papers, as are read at 
their accuftomed meetings, or to the perfons, through 
whofe hands they receive them, are to be coniidered 
in no other light, than as a matter of civility, in re- 
turn for the refpedt fliewn to the Society by thofe 
communications. The like alfo is to be faid with 
regard to the feveral projedts, inventions, and curio- 
fities of various kinds, which are often exhibited to 
the Society 3 the authors whereof, or thofe who ex- 
hibit them, frequently take the liberty to report, and 
even to certify in the public news-papers, that they 
have met with the higheft applaufe and approbation. 
And therefore it is hoped, that no regard will here- 
after be paid to fuch reports, and public notices ; 
which in fome inftances have been too lightly cre- 
dited, to the difhonour of the Society.
