MAOFILMED

ARD

THE prefent volume bas been detained an unusual time in the press, partly by the engagements of some of the authors, who have revised their papers for publication; and partly by delays attending the execution of the engravings. The number of materials bas likewise rendered this volume larger than either of the former, and consequently lengthened the time of impreffion.

From the institution of the new class of CORRESPONDING Members, the Society may expect an extension of communications; while the method of printing to be pursued in future, * by furnishing an early circulation of every ejay, among literary men, may induce the HONORARY Members, at large, to impart their obfervations or discoveries still more frequently.

The Society must repeat the declaration, prefixed to their first volume, that responsibility for the truth of faĉts, or justness of opinions, to be found in this volume, rests with their respective authors. To encourage scientific exertions is the grand object of the institution ; and the Society gladly acknowledges that the public has treated its endeavours with equal indulgence and favour.

* See the Laws annexed.
