joint. . ‘Vint Pome Aine de I Université Royale de Chris- 
tiania. 56 pp. 4to, with a chart, 9 photographs, and a lithographic 
plate. Chitianis, 187 0.—We cite here a few facts from this i impor- 
tant memoir. The great névé of Justedal covers a high plateau, 
lying between Sogn on one side and the Nordfiord and Séndfiord 
on the other, having a height of 1400 to 1650 meters above the 
sea, but passing northeastward into a chain of mountains, the cul- 
minati ing summits of which are the Lodalskaobe, 2076 meters in 
hess, parent it descends the valley of Viksdalen into the Séndfiord. 
The ‘length of the névé region is thus about 42 miles, and its sur- 
face over nine hundred square miles. 
fj aciers of the first class that descend from the snow- 
plateau are those of—1, Vetelfiord ; 2, Boium; 3 and 4, Suphelle; 
5, Langedal; 6, 7, Optag; 8, Austerdal ; 9, Tunsbergdal ; 10, 11, 
12, Bergset; 13, Nigar; 14, Faobergstol ; 15, Lodal; 16, Stege- 
“eh er Gredung Bad al; 19, Ne sda is 20 Aobrekke; 21, 
Brigsdal ; 22, Melkevold 23, Fo nd, in the valley of Stardal ; 2 
Lunde. ‘After numerous measurements of the rate of progress 
the movement of the ice in the glaciers of Boium, of Tonehengal 
and of Lodal, in the course of the month of August, the author 
gives the following as the mean results. 
In the case of the glacier of Boium, the rate per hour near its 
extremity was 0°28 in. pao tt and English) ; ; 3,000 feet above 
the extremity it was 0°66 i 8 yards from the oe convex 
side, 0°87 in. at the middle, mite o- 81 about 100 m the 
opposite or more convex side; while at points vag the less con- 
vex side within 20 to 40 yards of the margin the rate was 0°16 im. 
to 0°20 in. an hour. 
For the glacier of Tunsbergdal, the rate per hour near the ex- 
tremity was 0°23 in.; about 2,900 feet above it was 0°37 in. 135 
yards from the concave side ; about the middle 0°41 in. to 0°51 in. ; 
and toward the convex side 0°62 in. to 0°63 in. 
For the glacier of Lodal, the rate per ar, about 490 yards 
above the extremity, was at the middle 0-104 in. to 0-091; about 
1,875 yards above the extremity 0°183 in., 0°218 in. and 0° 212 in; 
about 2 500 yards from the extremity, just below where the two 
_ tributary glaciers come in from the right and left, 0°047 in. 
ear the margin; 100 yards from this margin, 0°140 in. ; ‘about th @ 
middle of the glacier 0°279 in. ‘297 in. 
tat author states vee the inelnation of the surface beneath the 
glacier where the measurements were made is about the same for 
each, and that the aiferonce ve the rate - motion depended on 
the pressure from the upper eng of = lacier. This pressure, 
was, ‘‘iseetoak,; much the greatest for the glacier of Boium. The
