SIR,

was worthy attention, and the notice of the Royal So- 
ciety. 
His lordfhip was pleafed, in 1757, to lay before the 
Society my letter, which is inferted in vol. L. of the 
Philofophical Tranfailions; and now, sir, to a worthy 
and refpedlable fucceflor, whofe life, health, and for- 
tune, have been molt generoufly adventured for the pro- 
moting natural knowledge, I addrefs this, to impart the 
refult of a long and ftrict inquiry.
