To Dr. John Woodward
Sir,
The Philosophy of Generation, was become one Subject of a short Contemplation with your Servant.
I thought, Among the Vegetables, the least Part of that which we call, The Seed, is really so. The True Seed lies in so Little Room, that it is not visible to the Naked Eye: The Rest serves but as a Lodging for it, and for its most proper Nourishment and Expansion at the first Opening of it. But in that little Room there lies the whole Plant, in all the True Parts of it; which is afterwards evolved, and extended, and filled up with its Adventitious Nutriment, until it be carried as far as the original Stamina, are capable. And then, the Growth stops. But perhaps towards the Period of the Growth, so weak may be the Stamina, that according to the Strength of the Soyl in which the Plant is lodged, the Growth may be more or less, tho’ but a little, varied.
And then I thought, why may not the Seeds of Animals, have the like said of them? Yea, The Microscopical Inquisitions, have made it more than probable; That the True Seeds of Animals, floating in their Suitable Vehicle, have, lying in a Space much less than the Naked Eye can discern, the whole Bodies of the Animals, even to all their Nerves and Fibres:
which afterwards Grow as aforesaid, until their original Stamina can be no further carried out.
