For the fame reafon that plants come in 
time to maturity, and {well under the cover 
wherein the flower lies, as the infect does in 
the Nymph: fo likewife we obferve, that in- 
fects infenfibly approach toa more perfect matu- 
rity, and by flow degrees {pring in their cover- 
ing, or the Nymph, in which are all their 
limbs, as the flower is placed in its proper 
- covering: this we fhall hereafter demonftrate in 
the Clove Julyflower, Tab. XLVI. 4. 
Laftly, as flowers at length break out from 
their husks, and become capable of producing 
new ones by generation and running up into 
feed; in like manner infects proceed from their 
Nymph, as the flower from the husk, and are 
alfo rendered fit for generation and repofiting

their fperm. And as propagation is performed 
in plants, by the union of their feed with 
the moifture of the earth’s womb, infects per- 
form the act of generation, by the conjunction 
of the fruitful, and, as it were invifible parti- 
cles of the male’s fperm, with the confpicuous, 
vivifick, and fenfitive feed in the female. | This 
feed of the female continues and perfects the 
life, motion and fenfe which it enjoys, when 
the {permatic virtue of the male is thrown into 
it; and it is in this continuance of motion that 
the fruitful conception of the feed is properly 
faid to confift: but we fhall hereafter explain 
this matter more at large, by particular exam- 
ples. 
A catalogue of the infetts which are referred to in the firft order of natural 
changes, called the Nympb-animal. 
AVING explained our firft and moft 
fimple order of changes, in which we 
have confidered the animalcule, which comes 
perfect from the egg, as a real Nymph when 
it is about to caft its laft fkin; it now remains, 
that we fhould give a catalogue of infects which 
belong to this order: and upon this occafion 
we {hall briefly enumerate fuch of them as we 
have in our cuftody, as we fhall do alfo with 
regard to the Nymphs, Chryfallides, and di- 
ftin& f{pecimens of the four orders, together 
with feveral other things not unworthy the 
{peculation of the curious, which we preferve 
in our cabinet, and by the affiftance of which 
we are able to demonftrate to the eye every 
thing hitherto, and that fhall hereafter be, ad- 
vanced. 
To the firft order of tranfmutations belongs 
the Spider *, which proceeds immediately from 
its egg, and has no vermicular ftate; this has 
been alfo obferved by the moft accurate Martin 
Lifter, who in his elaborate treatife on Spi- 
ders fays, ‘* Thefe are hatched from the eggs, 
“perfect and complete in all their parts.” 
Chap. II. Of the generation of Spiders. 
I keep, for this purpofe, the largeft of all 
Spiders, that is, the venemous, Brafilian kind, 
which has crooked, black, very fharp and big 
claws, or rather darts, and alfo has two arms, 
which are in all refpects like thanks or legs. 
I alfo have the great downy Phalangium, or 
Tarantula. 
Alfo a very remarkable Spider which Dr. 
Padbrugge fent me from the Cape of Good 
Hope. It is of the colour of fcarlet velvet, 
and covered thick with a fine down, in which 
is the colour. It is as big as a grain of a {mall 
French bean, with an oblong body, and broad 
breaft ; it has fhort legs, except the two fore- 
moft pair, which are very long; the fecond pair 
are fomewhat fhorter; the third is very fhort ; 
but the fourth or laft is fomewhat longer, and 
all of them are covered thick with red hair. 
The breaft is fo clofely united to the belly, that 
they cannot be fepdrated from one another ; 
therefore this Spider is in that refpe@ like a 
Lobfter; it has two fhort arms, and two ruddy 
tranfparent ftings or darts, but its eyes can’t 
be feen on account of the thicknefs of the 
hair. 
I have alfo the American fpecies of Spiders, 
which has rough, thick, and very long legs in 
comparifon of the body; the belly is fomewhat 
{welled and briftly, its darts are very much bent 
and crooked like claws, but the arms are fhort 
in comparifon of the legs, being not above a 
third part of the length of the fore pair. It 
has eight eyes, which are neatly ranged in 
two rows; its breaft is like an oval fhield ; it 
turns the eyes to the extreme parts, and bends 
itfelf a little on the infide, behind the joint of 
each leg or fhank, in the fame manner as the 
fkin finks between the ribs in lean and thin 
people ; but this is common to a great many 
Spiders big and little. 
I have alfo one of the Holland {pinning 
Spiders, which, in colour and figure, refembles 
Mouffet’s largeft fpinner, but it is not half fo 
large. I have obferved in this fpecies, that 
each of its eight legs confifts of feven joints ; 
thus the firft joint at the breaft is very fhort ; 
the fecond is much fhorter and formed like a 
ball ; the third is the longeft of all; and it is 
for the fake of this only, that the other joint 
‘ feems to have been made, that this third joint » 
may be moved with the greater eafe and expe- 
dition; the fourth is fomewhat bent, and by 
degrees grows thicker; the fifth is the longeft 
except the third; the fixth and feventh decreafe 
in proportion, whereof the latter is provided 
* The generical charaéters of the Spider kind, as eftablifhed by Linncus,. are, that they have eight legs, and the fame 
number of eyes, placed on the back part of the thorax. 
‘of this genus; and thefe diftinétive marks exclude fome infects, 
The common houfe Spider, the water Spider, ‘Tarantula, and others, are 
called by others by the fame name, placing them under other 
heads. The long-legged Spider having but two eyes, is properly an Acarus.
