towards L and beyond is thus reversed, at present chiefly 
from Obi and Lena, towards and beyond Pn, and circulates 
within the zone. Segment Pr has been thus not merely 
depressed from north to south, and moved toward S to the 
incline of 23 0 28' with meridian Pr, but its northern end has 
been cut off from west to east in proportion 1 : 4*78 to the 
middle sedtion, as the southern end was cut off in the oppo- 
site direction. It became divided into islands. The normal 
latitude of partition 34 0 20' from Pn is indicated by 3 0 52' 
south of Cape Farewell by the junction of the waters flowing 
east and west of Greenland on their return towards the 
equator. 
The more the segment increases in size and becomes in- 
clined to the meridian, and the polar sedtion itself increases, 
the more the latter gets similarly as at the south reversed in 
shape, the point south, the broad end north, until it pene- 
trates like a wedge between the north middle sedtion of Pr 
and the north sedtion of Af. 
The reflux dividing segment Pr is gradually raised to an 
angle of 34 0 12 — 3° 52' (northern readtion) in the Gulf of 
Mexico by the projedtion north of South America, corre- 
sponding to the depression of the reflux south of Africa to 
34 0 12' S. lat., and the land bulges out all along west of the 
line of intensity, S, Pr, towards the north. 
The sedtion reaches east of S by southern readtion 3° 52' 
beyond the ardtic circle. Thus reaches the Graham’s group 
out of the antardtic circle, by readtion passing over Pn, Ap, 
and Ps ; and the ardtic sedtion Greenland reaches 3 0 52' x 2 
out of the ardtic circle, pointing south, however shortened, 
a shortening for which volcanic Iceland is the equivalent. 
The long axis of the south continent from near S to Cape 
Catorha and the basis S to Yucatan west inside Gulf are 
66° 32' ; the north and the east side are 46° 52'. From S to 
where the east side of the deutotype leaves the land we 
have 55 0 48'. 
The continent of the ardtic sedtion has a long axis of 
23 0 28', and a peninsular prolongation of 3 0 52' at its north- 
east. 
The Gulf of Mexico reaches io° 44' into the north sedtion 
from the south ; so does Hudson’s Bay from the north, in 
reciprocity with the Siberian peninsula of Ap, reaching 
io° 44' into the ardttic circle, and 180 0 of longitude distant. 
Hudson’s Bay, with James Bay, reaches 10*44+3° 52' from 
ardtic circle to South Florida, meridian Pr equivalent of 
James Bay. 
The apocentric segment is inclined 23°28'to meridian Ap ;
