III. All that has now been said with respect to the two stations on the Glacier des Bois, may be repeated with only numerical differences with respect to the two stations on the Glacier des Bossons; the one set of observations confirming the other. IV. In both glaciers the summer motion exceeds the winter motion in a greater proportion, as the station is lower, that is, exposed to more violent alternations of heat and cold; this we shall find to be general. Before continuing our deductions, we would call attention to the close relation which may be established between the mean temperature of any portion of the year, and the velocity of the glacier corresponding to it. This is done in Plate IV., exactly in the same way as I did when comparing my Travels, 2d edit., p. 371. 1-This explains a circumstance which has always hitherto been a difliculty to me; the united testimony of the best-informed inhabitants, not only at Chamouni but elsewhere (as at Zermatt and at the Simplon), to the effect that during winter the lowest end of a glacier, which terminates in a valley, does not greatly protrude, nor force the snow before it. This arises in fact from the comparative smallness of the motion which the tongue of such a glacier appears to possess, especially in winter. 1846. MOTION COMPARED WITH TEMPERATURE or THE AIR. 131 observations in the summer of 1842 with the corresponding changes of temperature. That is to say, I have projected by periods (corresponding to the int...
