ment from 'the Colli quamenium ^ fo that they feem all 
to have been actually exiftenc before the Incubation of 
the Hen. And what Svoammerdam has difcovered in the 
transformation of Infe&s, gives no fmall light to this, 
whilft he makes appear in the Explanation of the 13th 
Table ofthe General Hiftory of Infects, that in thofe large 
Erucas which feed upon Cabbage, if they be taken 
about the time they retire to be transformed into Ame- 
lias, and plung d often in warm Water to make a Rupture 
of the outer Skin, you will difcern thro the tranfparency 
of their fecond Membrane, all the parts of the Butterfly, 
the Trunk, Wings, Feelers, &c. folded up. But that 
after the Eruca is chang'd into an Aurelia, none of thefe 
parts can be difcerned, they are fo drencht with moi- 
fture, tho they be there a&ually form'd. Another Con- 
fideration is from the Analogy, which we may fuppofe 
between Plants and Animals. All Vegetables we fee 
do proceed ex Plantula, the Seeds of Vegetables being 
nothing elfe but little Plants of the fame kind folded up 
in Coats and Membranes : and from hence we may pro- 
bably conjefture that fo curioufly an organized Crea- 
ture as an Animal, is not the fudden product of a Fluid 
or Colliquamentum^ but does much rather proceed from 
an Animalcle of the fame kind, and has all its little 
Members folded up according to their feveral Joynts 
and Plicatures, which are afterwards enlarged and di- 
ftended, as we fee in Plants. Now tho this Confede- 
ration alone may feem not to bear much weight, yet be- 
ing joyn'd to the two former they do mutually ftrengthen 
each other. And indeed all the La^vs of Motion which 
are as yet difcovered, can give but a ver-y lame account 
of the forming of a Plant or Animal. We fee how wretch- 
edly Des Cartes came off when he began to apply them 
to this Subjeft 5 they are form'd 2 by Law9 yet unknown 
to Mankind, and it feems inoft probable that the Stamina 
of all the Plants and Animals that have been, or ever
