"The incident rays, a and b, being parallel before they reach the reflectors, are thrown off at unequal angles in respect to each other, for b fallson the mirror more obliquely than a, and consequently is thrown off more obliquely in a contraty direction, therefore, then angles of reflection being equal to those of incidence, the two rays meet at c." -Comstock 1850

"A screw is a cylinder with a helical proection winding around its circumference. This helix is called the thread of the screw. The distance that a point of the helix is drawn back or advanced in the direction of the length of the screw during one turn is called the pitch of the screw." —Hallock 1905
