    Object history
    At the meeting of the Royal Society on 4 May 1687, 'Part of a letter of Mr. Leewenhoeck of May 9, 1687, N.S. was read, containing some microscopical observation on the structure or constituent parts of the mealy pabulum of plants, included together with the embryo plants in the husk of the seed. This he had found in the kernel of a medlar-stone to consist of nothing else but conglomerated globules. The rest of this letter was ordered to be translated' (Birch 4:534).

    At the meeting of the Royal Society on 25 May 1687, ‘A letter of Mr. Leewenhoeck’s was read concerning coffee, first as to the growth and texture of the coffee-berry, wherein he found very much oil to be contained; in which oil he conceived the principal virtue of the coffee to lie; and prosecuting that notion he gave direction for roasting the berry, and making coffee drink after the best manner. In the conclusion he said, that the coffee-berries grow on a tree as big as our lime-trees, as he had been credibly informed’ (Birch 4:540).
