The Seeds of Purslane seem of very notable shapes, appearing through the Microscope shap’d somewhat like a nautilus or Schem. 20. Porcelane shell, as may be seen in the XX. Scheme, it being a small body, coyl’d round in the manner of a Spiral, at the greater end whereof, which represents the mouth or orifice of the Shell, there is left a little white transparent substance, like a skin, represented by BBBB, which seems to have been the place whereunto the stem was join’d. The whole surface of this Coclea or Shell, is cover’d over with abundance of little prominencies or buttons very orderly rang’d into Spiral rows, the shape of each of which seem’d much to resemble a Wart upon a mans hand. The order, variety, and curiosity in the shape of this little seed, makes it a very pleasant object for the Microscope, one of them being cut asunder with a very sharp Penknife, discover’d this carved Casket to be of a brownish red, and somewhat transparent substance, and manifested the inside to be fill’d with a whitish green substance or pulp, the Bed wherein the seminal principle lies invelop’d.
There are multitudes of other seeds which in shape represent or
imitate the forms of divers other sorts of Shells: as the seed of
Scurvy-grass very much resembles the make of a Concha
Venerea, a kind of Purcelane Shell; others represent several sorts of
larger fruits, sweat Marjerome and Pot-marjerome represent Olives. Carret
seeds are like a cleft of a Coco-Nut Husk, others are like Artificial
things, as Succory seeds are like a Quiver full of Arrows, the seeds of
Amaranthus are of an exceeding lovely shape, somewhat like an Eye:
The skin of the black and shrivled seeds of Onyons and Leeks, are all
over knobbed like a Seals skin. Sorrel has a pretty black shining
three-square seed, which is picked at both ends with three ridges, that
are bent the whole length of it. It were almost endless to reckon up the
several shapes, they are so many and so various; Leaving them therefore
to the curious observer, I shall proceed to the Observations on the parts
of Animals.
