On the entrance slope occurred the only fatal accident I know of in glacières. In 1866, the Bavarian minister Freiherr von Lerchenfeld tried to descend; a wooden handrail which had been erected over the snow broke under his weight; von Lerchenfeld fell to the bottom of the cave and died a few days after from the injuries he received. Of the Kolowratshöhle, we have numerous thermometric observations by Professor Fugger, of which I select a few. DATE. OUTSIDE. ENTRANCE. INSIDE.

(Fugger, _Beobachtungen in den Eishöhlen des Untersberges_, page 80.)--On the southeast slope of the Untersberg near Salzburg, at an altitude of 1580 meters. The path leads past the Kienbergalp over the Mitterkaser and the Sandkaser. In front of the entrance is a sort of rock dam, 30 meters long and 5 meters or 6 meters higher than the entrance. Masses of snow fill the space between the two. The entrance is about 20 meters wide and from 2 meters to 3 meters high. A snow slope of 25 meters in length, set at an angle of 25°, leads to the ice floor. The cave is 54 meters long, from 13 meters to 22 meters broad and from 4 meters to 10 meters high. The cave has been repeatedly examined by Fugger, who has always found most snow and ice in the beginning of the hot weather, after which it gradually dwindles away. Of the Schellenberger Eisgrotte, we have the following thermometric observations by Professor Fugger:-- DATE. OUTSIDE. ENTRANCE.
