I acquainted you before, that I had examine feme of 
the fmalleft Particles of the Cochineel 5 xlj only nni was 
tobefatisfy'd, (as I fuppos'd,) that they were the Trunks 
or Bodiesof the Male-Flie^ and indeed we fee, that in 
all fmall Flies, that are produced from Worms or Mag^ 
gots, (at leaft 'tis my obfervation) the fmalleft are always 
the Males 5 and this Rule holds good alio in Flies and 
Lice, among which alfo, the hinder parts of their Fc^ 
male Bodies are always bigger, by reafon of their being 
fo often impregnated with Eggsj but when I thought 
I was fure that the little ones were all Males, and had 
foakt their Trunks thoroughly in Water, in order to 
fome further Inquiries^ I then imagin d, [that all the Co- 
chineel Flies are Females, and that Hardly one fourth 
Part of 'em was arrived to their full growth, before that 
their Bodies are filFd with young 5 but thefe are only 
Surmifesthat occurrd tome at that time. 
This Pofition of mine, that all the Cochineel Flies are 
Females, may feem very ftrange, and perhaps not meet 
with credit by thofe that maintain there can be no Ani- 
mal generated without a Copulation of Male and Fe- 
male 5 but they would be of another opinion if they 
had feen the unfpeakable number of Animalcula, which 
laft Summer infefted the Leaves of the Lira^-trees, or thofe 
other that were found upon Currant Trees., Cherry Trees. ' 
or t-Iazel-Nut Trees, all which Animalcula bring forth 
young alive, and thefe young ones being very little, hsv€ 
their Bodies filFd with other young, and are all Females, 
and confequentSy there is no Copulation among them : 
thefe, when they are full grown get Wings, fo that there 
is no other Change ill them, than iocreafing in bulk, anJ 
the fprouting out of Wings. 
^3ow if this be true in thefe above- mentioned Ani- 
malcula, akho they are fifty times fmaller than the Co- 
chineel Flies, we may eafily believe the fame of thefe ai- 
fo, efpecially fince the hinder parts of all of em are 
Uuuuuuuuu2^ much
