Birch, History, vol. IV, p. 32, 1 April 1680 (O.S.) in London:

Mr. LEEWENHOECK's letter to Mr. HOOKE, who had translated the sense of it into English, was read, giving an account of some farther discoveries of his about the eel-like worms in the seed of a rat; as also of the motion of the gills of muscles [mussels], oisters, &c.

It was ordered, that these should be examined at the next meeting, in order to which Mr. HUNT was directed to procure some oisters and muscles.
