THE SEED is that important Part which of the Seed is the Medium of all Vegetable Propagation and of Plants. Production ; it is most intimately contain’d in this Year's Plant, and the next Year's Plant is most intimately contain'd in it. This is both the Beginning and End of the Vegetable State.
The Parts of which the Seed of a Plant doth Its Parts. consist, are (1.) The Embryo or Plantule, being Embryo-Plant the future Plant in Miniature, and is call'd the Gem or Bud; this adheres to (2.)

The Seed receives its Fecundity, as I before hinted, from the Genital Parts in the Flower, and being now committed to the Earth, proceeds to vegetate as follows.

Plantule. Warmth of the two great Parents the Sun and Earıb, begins to expand and protrude, or shoot forth its Radule or tender Root downward in the Earth, and the Plumule or Infant-Plant upwards; the small Radicles absorb the nutritious Juices, which causes the Plumule to grow and increase to the destined Size of the Plant: But till the Root is shot, and able to procure Nourishment, the Plantule is nourish'd from the Substance of the Placente or Cotyledons, which it draws to itself by an infinite Number of little Filaments callid Funes Umbilicales, or Navel-Strings, and by Botanists the Seed-Root. By this means the EmbryoPlant receives the cruder Juices of the Earth prepared and purified, being strain'd thro' the very Substance of the Placenta. When the Root is Gg2
able to provide for a Plant, the Cotyledons, or two Lobes of the Placenta, perish, and the Plant may be said to be deliver'd of its Young or Fætal Plant: So analogous is the Process of

OSTÉOLOGY, (according to the learned ofteology di. Boerbaave) is divided into three Parts, viz. (1.) vided into Osteogeny; which treats of the Origin of the Bones, Osteogeny, of what Matter they consist, and the Condition of the Bones in their proper Substance when actually form’d. (2.) Osteography, which teaches of ecgraphy, the Knowledge of the Stručture of the Sceleton or Fabric of the Bones, and the Diversity of Parts in the Bone itself now perfect. (3.) Synosteology, or Synofteology. Synosteography; which explains all the parts of a Bone, by means of which a Bone is connected or joined to a Bone, with Motion, or without Motion ; with a Cartilage, or without it.
SARCOLOGY also has a threefold Divi. Sarcology is fion, viz. (1) Myology, which teaches the Do- divided into ctrine of the Muscles. (2.) Splanchnology, which
