Tranfatiiom ■ which was accordingly done upon the 
2 6 ojf March 175-2. And the grounds of their choice 
are, and will continue to be, the importance or fingu- 
larity of the fubje&s, or the advantageous manner of 
treating them ; without pretending to anfwer for the 
certainty of the fadts, or propriety of the reafonings, 
contained in the feveral papers fo publifhed, which 
muft flill reft on the credit or judgement 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 fuch papers, as are read at 
their accuftomed meetings, or to the perfons, thro 
whofe hands they receive them, are to be confidered 
in no other light, than as a matter of civility, in re- 
turn for the refpedt fhewn to the Society by thofe 
communications. The like alfo is to be faid with 
regard to the feveral projects, inventions, and curio- 
fities of various kinds, which are often exhibited to 
the Society ; 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 highcft 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 infbmces have been too lightly cre- 
dited, to the difhonour of the Society.
