The Seeofen. (A. Posselt-Csorich, _Zeitschrift des Deutschen und Oesterreichischen Alpen Verein_, 1880, page 270.) On the Hean Krail in the Tennengebirge, at an altitude of about 1900 meters. The entrance faces southwest, and is 6 meters high and 4.5 meters wide. The cave is 25 meters long, and 8 meters wide. The floor of the cave is 13 meters below the entrance. The Posselthöhle. (A. Posselt-Csorich, _Zeitschrift des Deutschen und Osterreichischen Alpen Verein_, 1880, page 273.)--Named after its discoverer. It lies on the Hochkogel in the Tennengebirge, at an altitude of about 1900 meters. The entrance faces southwest, and is about 8 meters high and 8 meters wide. From the entrance the cave first rises, then sinks again below the level of the entrance, where the ice begins. The cave is about 20 meters wide. About 180 meters were explored, to a point where a perpendicular ice wall, 6 meters high, barred the way. About 125 meters from the entrance, there was an ice cone about 7 meters high. The Gamsloch or Diebshöhle. (Fugger, _Eishöhlen_, page 14.)--It lies on the Breithorn of the Steinernes Meer, near the Riemannhauss, at an altitude of about 2180 meters. The entrance faces south. There is first a small, then a larger chamber. The latter is some 40 meters long, by 5 meters or 6 meters wide. The ice is in the large chamber. Eishöhle am Seilerer. (Fugger, _Eishöhlen_, page 15.)--On the eastern side of the Seilerer arête on the Ewigen Schneeberg, west of Bischofshofen, at an altitude of about 2400 meters, is a small glacière cave. Cave in the Hagengebirge, West of Pass Lueg. (Fugger, _Eishöhlen_, page 15.)--It lies about 2 kilometers east of Kalbersberg, at an altitude of about 2000 meters. A snow slope, with an ice floor at the bottom, leads into a long cave, about which little is known. The Nixloch. Described in Part I., page 57. (Fugger, _Eishöhlen_, page 98.)--Professor Fugger gathered some valuable data in connection with the Nixloch. In August, 1879, he found the air current entering downwards; on September 14th, 1879, there was no current either way. On Christmas day, 1878, on the contrary, the draughts were reversed, pouring out of the hole with a temperature of +7.4°: the outside air then being -7.4°. At this time the known lower opening was in existence. The Kolowratshöhle. Described in Part I., page 18. (Fugger, _Beobachtungen_, etc., page 7.)--This cavern has been more carefully studied than any other glacière cave. Some of its dimensions are given by Professor Fugger as follows: From the entrance to the ice floor, 26.6 meters; surface covered by ice as measured on a plane, 2940 square meters; approximate cubical measure of entire cave, 92,000 cubic meters. The height of the entrance is 7 meters, with a width at the base of 2.7 meters, and at the top of 6.6 meters.
