The first title-page, given above, with a blank leaf attached, appears to have been printed in order that it might be substituted for the title-page of the 1614 edition of the Descriptio by those who desired to have the two works on logarithms bound together. In such cases the 1614 title-page is usually cut out and the new one pasted on in its place. Consequently, in these copies, we find the same varieties as mentioned in the preceding entry. In other copies, however, only the new title-page and blank leaf are inserted before the Constructio.
