In his article entitled "On the manufacture of diffraction gratings and theoretical," the paper wrote,"If every inch with the same number of two engraved lines in contact with photographic copies of the state, the two grating The engraved lines are almost parallel will result in a set of parallel stripes, the direction of the two grating carved exterior angle between the line bisection, and their distance decreases with increasing inclination."

他在一篇题为"关于衍射光栅的制造和理论"的论文中写到"如果把每英寸具有同样数目的刻线的两个照相复制品处于接触状态，使两个光栅中的刻线几乎平行则就会产生一组平行的条纹，其方向将两个光栅刻线之间的外角二等分，而其距离随着倾角的减小而增大"。

Say for example, when discussing on parallel axiom, which is "given a point and a line on a plane, there exists a unique line on the plan that passes through the point and is parallel to the line", if we change the axiom as "there is not any or there are infinitely many lines that will pass through the point and be parallel to the line", then we have two kinds of non-Euclidian geometry.

就像对于平行公理的讨论一样，干脆规定：过已知直线外一个固定点可以作无数条与已知直线平行的直线；或者过已知直线外一个固定点的任何直线都不能与已知直线平行；这样还产生了两个版本的非欧几何。
