The Explanation of the 3d and 4th Tables.

I have in both these Tables used the same letters, for that the Explanation required it; as also for that they represent the entire dissection of the Worm; so that what letters are wanting in the third Table may be found in the fourth: as also those which are wanting in the fourth may be found in the third.
