I likew^^hold, that certain migrating fish, Mich as 
mackerel', CVring, &c are forced up from Die mi<ffda ne . 
space, at or. var the verge, in the neighborhood oflce- 
land, and that vie tide is raised by water forced out from 
the mid-plane-Space; that the nearer the verge, the 
more forceful is it expelled, as the Maalstrom affords an 
evidence; that the lower surface of this space affords ! 
fresher water than the other; that it is in a considerable 
degree probable, that the cake ice, drifted trees, &c. &c. 1 
which bear against the North shore of Iceland in the 
spring season, are expelled, like those herring, &c. from 
the lower surface of the mid plane-space. 
The hne of the verge is probably often indicated at 
sea by a disagreement between the log and celestial ob¬ 
servation,^ when crossing it ; and the clock and sun 
must, I think, necessarily disagree, more or less, at the 
sometime. On land, the line of the verge, it appears, 
is seldom crossed either way, by migrating quadrupeds, 
or water fowl. 1 
!or a like application of these particulars, see the Map 
the Verge, which I published in September, 1822. 
Respectfully, &c.
