Birch, History, vol IV, p. 464, 10 March 1686 (O.S.) in London:
A part of Mr. LEEWENHOECK's letter was read, containing his observations upon gall and the scales, and slime of the eel and the bream; which slime, he said, he had discovered to be parts of the body of the fish, and to consist of a great number of vessels interwoven together; describing the manner how these vessels came out of the scales, that lie under it. The rest of the letter was referred to another meeting.
