"The first of these books deals with arithmetic using fractions, and the second deals with decimal numbers. His decimal notation is particularly crude, using a vertical bar ( | ) for the decimal separator, and also using 1, 2, 3, 4, etc. above each of the decimal digits to designate its position. The second book on decimals has a separate title page. Johnson uses the galley method of division throughout" (Tomash & Williams). ESTC gives the pagination as [12], 169, 158-521, [1]pp.; this copy ends with the colophon on p.421.
