The Chourun Clot. (E. A. Martel, _Sous Terre_. _Annuaire du Club Alpin Français_, vol. XXIII., 1896, pages 42, 43; _Mémoires de la Société de Spéléologie_, vol. I., page 31.)--In Dauphiné, half way between Agnières and the Pic Costebelle, at an altitude of 1,740 meters. There is first a pit 18 meters long, 4.50 meters wide and 25 meters deep. In the bottom of this is a vertical hole 15 meters deep and from 1 meter to 2 meters in diameter, in which there was much ice on the 31st of July, 1896. Then the pit changes to a sloping gallery which terminates in a little hall, full of ice, at a depth of 70 meters. Martel gives a cut and section of this glacière. The Glacière du Trou de Glas. (E. A. Martel, _La Géographie_, 1900, vol. I., page 52.)--In the range of the Grande Chartreuse. The Chourun Martin. (E. A. Martel, _La Géographie_, 1900, vol. I., page 53.)--In the range of the Dévoluy, Hautes-Alpes; altitude 1,580 meters. An extremely deep pit, which on July 31st, 1899, was much blocked up with snow. The Chourun de la Parza. (E. A. Martel, _La Géographie_, 1900, vol. I., page 54.)--In the range of the Dévoluy, Hautes-Alpes; altitude 1,725 meters. A fine pit, 25 meters in diameter, and 74 meters in depth. Filled with snow or rather névé, in which are deep holes. The Glacière de l'Haut-d'Aviernoz. Described in Part I., page 2. (C. Dunant, _Le Parmelan et ses Lapiaz_, page 26; Browne, _Ice Caves_, etc., page 157.)--Mons. Dunant calls this glacière l'Haut d'Aviernoz; Mr. Browne calls it the Glacière du Grand Anu. By a plumb line held from the edge of the larger pit, Browne found that the ice floor was about 35 meters from the surface, which would give a level for the ice floor closely identical to the one I found. In July, 1864, he recorded a temperature of +1.1°. The Glacière de l'Enfer. (G. F. Browne, _Good Words_, November, 1866; T. G. Bonney, _The Alpine Regions_, 1868, pages 95, 96; C. Dunant, _Le Parmelan et ses Lapiaz_, page 25.)--On Mont Parmelan. A pit cave with a steep slope of broken rock leading to a rock portal in the face of a low cliff. This opens into a roughly circular hall about 22 meters in diameter and 3 meters to 4 meters in height. A chink between the rock and the ice permitted Mr. Browne to scramble down three or four meters to where a tunnel entered the ice mass. Throwing a log of wood down this tunnel, a crash was heard and then a splash of water, and then a strange gulping sound. "The tunnel obviously led to a subglacial reservoir and this was probably covered by a thin crust of ice; the log in falling had broken this and then disturbed the water below, which then commenced bubbling up and down through the hole, and making a gulping noise, just as it does sometimes when oscillating up and down in a pipe."
