T HE appearance of the prefent half volume, 
demands an explanation from the Soctety.—A defire to 
fulfil its engagement with the public as far as cir- 
cumflances would permit—and alfo to comply with an 
exprefs law of great importance to tts tnterefts, have 
induced the Society to offer the prefent publication as 
the firfi part of a volume, which was promifed 
to be brought forward every two years.—It is the 
intention of the Society to publifh a fecond. part early 
in the year 1794.—Unavotdable delays, occafioned by 
the pre-occupation of the prefs, and the dilatorinefs of 
engravers, have protracted this firft part of the fourth 
volume feyond the limited term.—The Society muft again 
repeat, as a general declaration, that re{ponfitility for the 
truth of facls, or juftnefs of opinions, to be found in this 
or any future volume, refis with their, refpeclive authors. 
The favourable reception by the public of the former 
volumes of thefe Memcirs, at the fume time that it 
demands the warmeft acknowledgments of the Society, witi 
Serve powerfully to excite its future exertions.
