IV. Part of a letter from Mr. Benj Cooke, F. R. S. To Mr. Peter Collinson, F. R. S. concerning the effects of the mixture of the farina of apple-trees; and of the Mayze or Indian corn: of a child born with the jaundice upon it, received from its father; and of the mother taking the same distemper from her husband, the next time of being with child

Abstract

When the Farina of one Apple impregnates another’s Blossom of differing Species, we see the Change in the Fruit; but whether any lasting Impression, is left on the Bough which bore it (as seems to be in Tulips and some other Flowers), is not so easy to determine, Experiments of this sort being not to be made at all, but catch’d at distant Opportunities; and till this Point is settled, the Distemper of my good Friend's Tree must rest unexplained.
