ved by thofe that are furntflied with both; and therefore I (hall only 
add, that if any one eife hath made ufe, or thought of the like con- 
trivance, it is more than I know ; And withal), that though the one

as fwiftly, by thefhrinking and fwelling of the boards. 
I have here withal fent you the Figure of an admirable inftance 
Tab I of Natures luxuriancy in hercontrivance even of Infefls. 
Fig.'al Tis a Kind of large flying Beetle, ofadark fliining brown, 
with a huge pair of horns , Cin proportion to the body. ) 
fbaped and branched exaftly like aStaggs, orHarts/roni which hft 
it hath its denomination ; Our people in Virgima, and Nerv Eng- 
Imd cd\\\x\g it a Flying Hart. It flies high and fwifr, and refts moil

my employment were both unfavorable tomy defire , and I was 
therefore forced to defift without further fatisfaftion. 
Though the Author in Numlp,2j. of your Tranfaciions feems in-
