Mr. Hooke produced a translation of the long letter lately received from Mr. Leewenhoeck, and dated 4 Nov. 1681, N. S. which he read; containing an account of divers observations and discoveries, which he had lately made concerning great numbers of small animals in his excrements, which were most numerous when he was troubled with a looseness, and very few or none, when he was well. He also found the same very observable in the excrements of other animals , &c.
