the impetuosity of their desires. Now the Species of the thing desir'd being in the Imagination, it excites the Appetite which desir'd it; this the motive Faculty, which employs the Animal Spirits to execute the commands of the Faculties by whom it is set on work. And as the Vertues and Images of things gene∣rated here below by the heat and influence of the Stars, are re∣ceiv'd in the Air which consigns them to the Earth; so those Spirits receive the Species and Images whereof the brain is full; and being directed by the Imagination to the Womb (which hath great communication with the Brain by means of the nerves of the sixt Pair, as appears by the effects of Odors upon that part) there they retrace and imprint upon the Child the Images wherewith they are laden. For, if it be true that the Imagina∣tion can act beyond its Subject, as Estriches and Tortoises are said to hatch their Eggs with their Eyes, and that Hens hatch Chickens of the colour of such cloths as are laid before them whilest they are sitting; much more may the Imagination of a Woman represent upon the tender Fruit in her womb the Ima∣ges of things which she passionately desires: and this is no more strange than the common observation, of People falling sick, and recovering again, meerly by Fancy.
The Third said, That the images of things desired are, in the Spirits, just as those of sensible objects are in the Air, which is full of them. But as these, that they may be seen, must be ter∣minated by a smooth and opake body; so, that those which are in the spirits may be express'd, they must be terminated by a soft, tender, and capable body, as a child's is in the first months of his conformation, during which alone he is susceptible of these impressions, which are only of things edible and potable; being the Child, then endu'd only with sensitive Life, cannot be affected but by things serving to the Animal Life, as aliments are, which (besides) are ordinarily and most ardently desir'd by breeding Women; those that long for chalk, coals, and other impurities being unhealthy and distemper'd. Now to give ac∣count why the Grapes, Mulberries, Strawberries, Goose-berries, and other Fruits delineated upon our bodies, ripen and change colour at the same time as the true fruits upon the earth do, I shall not recurr to the Stars, or Talismanical Figures, but more probably to that Universal Spirit which causeth the same fer∣mentation in the spirits of our bodies as in Wine and the Vine when it is in its sap and flower; and in Pork or Venison when Hogs and Deer are salt, mezled, or go to rut.
The fourth said, That some of these Marks adhere to parti∣cular Families. So the family of Seleucus had an Anchor upon the thigh; in Greece some were distinguish'd by a Lance, a Cre∣vish, a Star, &c. which marks, as Warts and Moles, proceed from the Formative Vertue in the seed, which containing the Idea of all the parts, expresses them to the life in the child. Other sorts of Marks are not ordinary but fortuitous, and depend
