Martin Folkes, Efq', 
Vice-Prefident of the Royal Society. 
Honoured Sir, 
I Shall not, I prefume, need any other Apo- 
logy for prefixing your Name to this Thirty 
Fourth Volume of Philofophical Tranjaftiom^ when 
I declare, that the Motive of my doing fo was 
tlie fame, which induc’d the greateft Man that e- 
ver liv’d, to fingle you out to fill his Chair, and 
to prefide in the Alfemblies of the Rojyal Society ^ 
when the frequent Returns of his Indifpofition 
would no longer permit him to attend them 
with his ufual Affiduity. 
This Motive, Sir, we all know, was your un- 
common Love to, and your lingular Jlttainments 
in thofe noble and manly Sciences, to which the 
Glory of Sir Ijaac Nerptony and the Reputation of 
the Royal Society is folely and entirely owing. 
That Great Man was fenliblc, that fome- 
thing^lnore than knowing the Name, the Shape 
and obvious Qualities of an Infcfl, a Pebble,, 
a Plant, ora Shell, was requifi*-^: t* form a 
Philofopher, even of the lowed rank, much 
more to qualifie one to fit at the Head of fo 
great and learned a Body. VVe all of us re« 
mernber that Saying fo frequently in his Mouth, 
That Natural Hiflory might indeed jurni/Jj Mate^
