Exp. 59. Use the same apparatus as in Exp. 58,with the addition of the tin, and, after the water hasreached the same level in each dish, raise first one, thenthe other, and watch the changing direction of the flow. Inferences. 1. Which, in each case, is the longer arm ofthe siphon ? 2. The length of each arm of a siphon is theperpendicular distance between the highest point of water init, and what other point or level ?
