The Royal Society read Letter L-144 of 1683-12-28 to Francis Aston

February 23, 1684

Birch, History, vol. IV, p. 254, 13 February 1683/4 (O.S.) in London:

An extract of a letter for Mr. LEEWENHOECK, dated at Delft December 28, 1683 was read, containing some farther observations of the scales growing upon men as they do on fishes: of the scales on the middle of the lips: of a scaly child: also an examination of the slimy matter or woolly substance within the guts: and an experiment, that water passes through a bladder, when wine will not.

This experiment was not looked upon as new, though the truth of it was not doubted of.
