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."

Mons. C. Dunant of the Club Alpin Français describes a visit to the Glacière de l’Enfer. He mentions also a legend of a witch from a neighboring village who would get the ice from these caves and bring it down in the shape of hail on the crops of the peasants who were inhospitable to her.

The Glacière de Chapuis. Described in Part I., [page 5]. (Browne, Ice Caves, etc., page 182, and Good Words, November, 1866.)—Mr. Browne calls it the Glacière de Chappet-Sur-Villaz. Mr. Browne and Professor T. G. Bonney found several flies in the Glacière de Chapuis. Three of them were specimens of Stenophylax, the largest being probably, but not certainly, S. hieroglyphicus of Stephens. Two smaller caddis flies were either S. testaceus of Pictet or some closely allied species. One other insect was an ichneumon of the genus Paniscus, of an unidentified species. It differed from all its congeners in the marking of the throat, resembling in this respect some species of Ophion. Mr. Browne thinks that the case flies may have been washed into the cave somehow or other in the larva form, and come to maturity on the ice where they had lodged. But this explanation will not hold in the case of the ichneumon, which is a parasitic genus on larvæ of terrestrial insects.

The Glacière de Le Brezon. (Pictet, Bibliothèque Universelle de Genève, 1822, vol. XX., page 270, and Thury, Bibliothèque Universelle de Genève, 1861, vol. X., pages 139 and 152.)—It lies southeast of Bonneville near the foot of Mount Lechaud, at an altitude of 1276 meters. The cave is 9.7 meters long, about 8 meters wide and the greatest height is about 4 meters. The entrance is small and is at the base of a cliff, in some places of which cold air currents issue. The ice lies on the floor. Some of it is probably winter snow.

The Grand Cave de Montarquis. Described in Part I., page 70. (Thury, Bibliothèque Universelle de Genève, vol. X., pages 135-153.)—Professor Thury describes two visits to this cave. On the 16th of August, 1859, he found no ice stalactites or stalagmites. On the 19th of January, 1861, he did not find a single drop of water in the cave, but many stalactites and stalagmites of beautiful clear ice, one of which resembled porcelain more than any other substance. In August, Thury found an air current streaming into the cave at the rear, but this did not, however, disturb the air of the interior, for in one part it was in perfect equilibrium: along the line of the draughts the ice was more melted than elsewhere in the cave. In January, the current was reversed and poured into the fissure, with the temperature varying between -1.5° and -2.5°. He observed the following temperatures at the Grand Cave:—
