The two general Parts of the _Seed_ are its _Covers_ and _Body_. The _Covers_ in this estate are usually four; the outmost we may call the _Case_: ’Tis of a very various form; sometimes a _Pouch_, as in _Nasturtium_, _Cochlearia_; a _Cod_, as in all _Pulse_, _Galega_; sometimes not entire, but parted, or otherwise open, as in _Sorrel_, _Knotgrass_, with many other forms; I think alwaies more heterogeneous to that of the _Seed_, by which it differs from the proper Coats. To this the Caps of _Nuts_, and the _Parenchyma’s_ of Fruits are analogous. The two next are properly the Coats: In a _Bean_ especially, and the like; from whence to avoyd Confusion, the denomination may run common to the responding Covers of other _Seeds_. The Colour of the outer is of all degrees, from White to the Blackness of _Jett_: Its Figure sometimes Kidney’d, as in _Alcea_, _Behen_, _Poppy_; triangular, as in _Polygonatum_, _Sorrel_; triangular spherical, in _Mentha_, _Melissa_; circular, in _Leucoium_, _Amaranthus_; globular, in _Napus_, _Asperula_; oval, in _Speculum Veneris_, _Tithymalus_; half Globe, in _Coriander_; that which we take for one single round _Seed_, being a Conjugation of two; half Oval, in _Anise_, _Fennel_; Hastal, in _Lactuca_; Cylindrical, as, if I mistake not, in _Jacobæa_, Pyramidal, in _Geranium_, _Althææ Fol._ with many other differences: But the Perfection of one or two of the said Figures lieth in the _Case_: So that as all Lines and Proportions are in the _Flower_, so all Regular Figures in the _Seed_, or rather in its _Covers_. ’Tis sometimes glistering, as in _Speculum Veneris_; Rough-cast, in _Catanance_; Studded, in _Behen_, _Blattaria_; Favous, in _Papaver_, _Antirrhinum_, _Lepidium annuum_, _Alcea Vesicaria_, _Hyosciamus_, and many more, before the _Seeds_ have lain long by; Pounced, in _Phalangium Cretæ_, _Lithospermum_; Ramified, in _Pentaphyllum fragiferum_, _Erectum majus_, resembling the Fibres of the Ears of the Heart; some just _Quinquenerval_, as in _Anisum_, and many more, the _Lignous Body_ being in five main Fibres branched therein. The Covers of not only _Quince_-Seeds, and those of _Psyllium_ (more usually taken notice of) but those also of _Horminum_, _Nasturtium_, _Eruca_, _Camelina_, _Ocymum_, and divers others, have a _Mucilage_; which, though it be not visible when the Seeds are throughly dry; yet lying a while in some warm Liquor, or only on the Tongue, it swells more or less, and upon them all fairly shews it self. On that of _Ocymum_ it appears grayish; on the other, transparent; and on that of _Nasturtium Hortense_ very large; even emulous of the inner Pulp surrounding a _Gooseberry-seed_. The putting of _Clary-seed_ into the Eye, may have been brought into use from this _Mucilage_, by which alone it may become Medicinal. And thus far of the _Superficies_.
