9- The males and females never live together, but with the greateft fear and circumfpedion 
indulge their mutual defires j in doing which they take up very little time, and, as if frightedj^, 
feparate from each other. After fuch interruptions, however, they occafionally repeat their 
embraces, till the female being impregnated, they very foon difaffociate. 
10. The abdomen in the female, after impregnation, fwells very much 5 and if the belly of 
a large female is opened, a large quantity of eggs may be plainly feen, which are contained in 
a feparate receptacle of a long fhape, and which equals a third part of the whole abdomen. 
11. Spiders are not all of equal fecundity j fome having only feven or eight eggs in a bag; 
whilft others have 50, 100, or even 150 in each bag, which are feven, eight, or ten in num- 
ber; infomuch that one female may lay a thoufand eggs in a fummer. 
12. The care of the eggs and young devolves upon the females alone, differently in the 
different fpecies ; but in moft, as in other infe6ls ; their eggs being hatched by the warmth of 
the air alone, without incubation. 
13. Though the young are not at firfl like their parents in colour and marks; yet they 
have the fame fhape as to their body, legs, 6cc. nor is it neceffary for them, as it is for moil: 
other infe6ls, to undergo a transformation, in order to acquire their genuine fhape. The co- 
lour and marks come gradually, fooner in fome than in others. 
14. I HAVE not obferved their age to exceed a year, but in other countries there may be 
fpecies which are longer lived. 
15. Whether our Spiders^ as fome are of opinion, injure men by biting, or to fpeak more 
properly, by lacerating with their claws ; or whether the infedls themfelves or their excre- 
ments imprudently fwallowed, be hurtful, mull be proved by farther experiments. I can 
only fay, that they have laid hold ftrongly on my fingers, and pricked them, without any 
harm following, and we know that chickens and fmall birds devour them greedily without 
fuffering any injury. 
16. I have not yet found any Spiders which are fnooth, but mofl of them abound more or 
lefs in bridles and prickles. 
17. Their excrement is always fluid, and refembling muddy water. 
18. I SHALL treat feparately of fuch as have two eyes only; whatever therefore is faid here 
mufl not be applied to them.
