A FORAMINIFEROUS DEPOSIT FROM THE NORTH ATLANTIC. 65 
The mushroom anchor took up not only a nearly pure 
stratum of foraminiferous ooze, but also a very clayey foramini- 
ferous stratum, in which were fine and coarse grains of quartz, 
mica, and other minerals, with pebbles, water-worn, of gneiss, 
hornblende, black and white limestones. But lavas compact 
and vesicular were abundant, one specimen weighing over a 
pound or two. One pebble of dark hard texture is apparently 
polished on one side, as if abraded by glacial action. 
The ooze contracted into a comparatively small volume, say 
one-fourth, after being kept in a dry room for a few months. 
Of the more highly foraminiferous stratum, about 507 was 
sand and clay insoluble in Hydrochloric acid. The equivalent 
of over 257% of carbonate of lime was precipitated as calcium 
sulphate from the filtrate. From the more argillaceous 
stratum 667% of sand, &e. was insoluble in HCl, while 
H, SO, precipitated but a few grains from the filtrate. This 
rough analysis was verified approximately by specimens of the 
two strata analyzed more carefully in the laboratory of Dal- 
housie College by Mr. J. M. Nissen. The difference between 
the two strata was sufficiently discernible to the naked eye, 
and clearly so by a close examination with a simple lens. 
The species of foraminifera are fairly numerous. The fol- 
lowing list of them has the authority of Mr. F. 8. Morton, 
F.R. M.S., of Portland, Maine, who compared them with the 
foraminifera described in the Challenger’s papers and more par- 
ticularly with those described in a “Synopsis of the Arctic and 
Scandinavian Recent Marine Foraminifera,” by Dr. Alex. Goés of 
Stockholm. which they more especially resemble. I have also to 
acknowledge the service of G. F. Matthew, M. A. F. R. S.C. 
of St. John, New Brunswick, in testing some of my observa- 
tions.
