VI.— A FORAMINIFEROUS DEPOSIT FROM BOTTOM OF THE 
NortTa ATLANTIC. By A. H. MacKay, LL. D. 
(Read 10th December, 1894.) 
The exact location of this deposit cannot be more tersely 
described than it is in the following note from Captain Trott, of 
the steamship Minia, dated Halifax, 31st April, 1894, which 
accompanied the material sent to Dr. Murphy, Provincial 
Engineer, who duly passed it on to me. 
“Herewith the stones I spoke to you about. They came 
“from a depth of 2450 fathoms, in latitude 49° £0! N., longitude 
“40° 15’ W. The current in this vicinity runs strong to N. E., 
“varying sometimes two or three points either way, doubtless 
“influenced by the moon. The surface temperature ranges from 
“54° to 59° Fahrenheit. This is as it is found nearly all the 
“months of June and July. <A little further west we found cold 
“water and very little current. JI am also sending some 
“ Globigerina ooze which came up in the same mushroom anchor 
with the stones—the anchor being full except on one side 
where it had beeu washed out while heaving up, thereby 
exposing the stones.”

The spot, roughly estimating, is therefore not far from 700 
miles south-easterly from Cape Farewell, Greenland, and some 
300 or 400 miles east from Labrador, or 300 miles east by north 
of Newfoundland. This is beyond the Great Banks and well 
down into the profounder depths of the Atlantic. It would 
appear then to he near the circle which, like the circumference 
of a vast oceanic eddy, lies tangential to the Gulf Stream on the 
south-east, the westerly Arctic current from Iceland to Green- 
land on the north, and the southerly Arctic current along the 
Labrador Coast. The character of the deposit suggests the exist- 
ence of such an eddy, no matter how circumscribed and swaying 
its position may be.
