schists, and other rocks, glauconite, and many fragments of highly 
altered rocks resembling glauconite. 
Siliceous organisms [ROO] : one or two Radiolarians and fragments 
of other siliceous organisms, and a few glauconitic casts. 
Fine washings [17 ’23]; fine mineral particles with argillaceous 
matter. 
Remarks. — The carbonate of lime consists chiefly of the remains of 
surface organisms. 
The feldspar is generally kaolinised; typical glauconite is found 
in grains more or less mammillated and furrowed ; some are quite 
green, while others are reddish coloured. Among the larger fragments 
are pieces of feldspathic sandstone (6 mm. in diameter) of granite 
and fine-grained mica schist. 
Sounding 17. Station 2. Lat 60° 29' N., long. 8° 19' E. 28th 
July. Depth, 375 fathoms. Surface temperature, 53*0°; bottom 
temperature, 31*0°. 
A small quantity of mud came up in the sounding tube, of which 
the following is a description : — 
Blub mud, plastic, coherent, with many rather large gritty par- 
ticles— streak lustrous. 
Carbonate of Calcium 14*20 per cent., consists of a few Coc- 
coliths, Globigerinas, a few Miliolinas, Botalias, Nonioninas, Trunca- 
tulinas, Ostracode valves, and fragments of Echini. 
Residue 85*80 per cent., brownish, consists of — 
Minerals [70*00], m. di. 25 mm,, with many particles over 1 mm. 
in diameter— quartz, mica, magnetite, feldspar, hornblende, glau- 
conite, augite, fragments of ancient and recent volcanic rocks. 
Siliceous organisms [2*00] : one or two Sponge spicules, glauconitic 
casts of Foraminifera, few Diatoms. 
Fine washings [13*80] ; fine mineral particles with argillaceous 
matter, and a very few fragments of siliceous organisms. 
Remarks. — The dredge, with two swabs and a bread bag in the 
netting, was put over at 8 p.m. on the 28th, and hauled in at 4 a.m. 
on 29th July. 
It contained over a quart of gravel and small stones, and some 
larger stones — some of them were covered with a thin coating of 
peroxide of manganese on one of their surfaces, and had many 
serpulse and polyzoa attached.
