[DESCRIPTION: Notes on "Stone work for locks of 3. chambers . . ." including calculations. Since it appears that the bottom of the sheet was intentionally cut, perhaps the "Stone work..." notes were were written on a piece of "scrap" paper which earlier held a longer "Measures..." note on the other side. See other side of page.]
