An AlftraEt of what is con t anted in the Pre- 
face to the Sixth V olume of Mon f Reaumur V 
Hiftory of Infedls, relating to the above- 
mentioned Obfervations , and delivered in to 
the Royal Society, immediately after the 
foregoing ‘Paper. 
A S the Sixth Volume of Monf. Reaumur's Hiftory 
of Infetfs , juft publiftfd at Raris, is not yet 
come over, foasto be met with among theBookfellers 
here : I thought a fhort Extract of what he there fays, 
in his Preface, relating to the Subjed of Monfteur 
Tremble/ s Paper, might not be unacceptable, to the 
Gentlemen of the Society prefent. 
He there obferves, that tho’, in the Hiftories he 
has already given of minute Animals in this Work, 
he has had occafion to produce many new and unex- 
peded Phenomena : One he has now to mention 
would exceed all Belief, if it was not confirmed by the 
ftrongeft repeated Obfervations 5 which is, that there 
are Species of Infeds, who are multiplied by being cut 
to Pieces, and among which, one ftngle Animal, di- 
vided into 8, 10, 20, 30, or 40 Parts, becomes fo ma- 
ny entire Animals, each fimilar to that of which it 
was at firft only a Piece. This Animal, being one of 
thofc that undergo no Change in their common Form, 
does not belong to the Defign of this prefent Volume, 
which treats only of fome of thofc, which, having been 
firft a Worm or Maggot, are then changed into aChry- 
falis, and from thence, either into a Fly or Scarabee.
