On finding 5~ne, Cosine, ~.c. ~2 l following postulate is given: the required intensity of resistance, to balance a given force, is proportional to the obliquil~l of that resistance to the given force. This is true, and may be usefully impressed. It reverses the assumption of Mr. Clifford, and makes the transmitted forces through the connecting-rods, in their own direetions, inversely as the cosines. Let $ P, be the short connecting-rod ir~ its return, corresponding with its position at S O,
