As for the introduction, in the name of the drawings of this machine, it includes the arc of elevation, which is divided from the sine into equal parts, on which are written their number directly to the sine and inverse to the sine, then the sexagesimal sine - f.2r.21: So go up from the intersection of the string. For the inverted fathom to the half diameter and then to the sixties, whatever number you find is the extended tangent, and if you want the inverted, enter from the intersections of the string to the fathom in the straightened to the sixties the limit of the inverted — f.2v.1, and this amount is sufficient. For those who want to work with this machine. I swear. Know . It was done correctly, and praise be to God alone
