filould judge mod: proper for publication in the future 
T'ranfahions j 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 fubjedls, or the advantageous manner of 
treating them j without pretending to anfwer for the 
certainty of the fads, or propriety of the reafonings, 
contained in the feveral papers fo publifhed, which 
muff dill red: on the credit or judgment of their re- 
Ipedive authors. 
It is likewife necelTary on this occafion to remark, 
that it is an eflablidied rule of the Society, to which 
they will always adhere, never to give their opinion, 
as a body, upon any fubjed, 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 accuffomed meetings, or to the perfons through 
whofe hands they receive them, are to be confidered 
in no other light than as a matter of civility, in re« 
turn for the relped diewn to the Society by thofe 
communications. The like alfo is to be faid with 
regard to the feveral projeds, inventions, and curio^ 
ficies of various kinds, which are often exhibited to 
the Society j 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 highefl applaufe and approbation. 
And therefore it is hoped, that no regard will here- 
altcr be paid to fuch reports, and public notices j 
which in fome indances have been too lightly cre- 
dited, to the dilhonour of the Society.
