Abstract
WITH apologies to Prof. Joly (p. 55), I think my estimate of a gradient of 1° F. for 98 feet in the Simplon Tunnel will bear examination. From a contemporary notice in the Daily Mail of October 3, 1904, it is clear that the heat in the tunnel was endurable until the hot spring was tapped. The water is stated to have been at 131° F., which agrees exactly with 55° C., “the highest temperature” of Prof. Joly. Surely, then, this was the temperature of the spring, and not of the rocks.
