A Geological Idea of Lord Bacon's. [September* 
By the overweight of the sea round Ps, consequent on a 
greater regional condensation of the nucleus by external in- 
fluences, the envelope at the south has been smoothed away 
from Ps, and raised and plicated towards the north. The 
mass above the lower zero level of land and sea has been 
increased at the north ; the interstratum, having been 
heated, expanded, made less dense and more elastic, by the 
fall, penetration, and internal heat effedft of water from the 
south. 
Folds are the accumulated remainders of continued oscil- 
lations : the world is built up by oscillations, all referable to 
gravity. 
I direCtiy conned the waves of sea and land, but a com- 
parison will more easily be appreciated. The number of 
vibrations of blades of equal material and dimensions, length 
excepted, are in equal times inversely as the squares of these 
lengths. Imagine land and sea formed into blades equally 
broad and thick, and fixed at respective points, poles, they 
will be in length i : 2*83. The sun is the bow setting them 
in vibration. 
If sea and land were of equal material the frequency of 
vibrations would be 2*83 2 : 1, but the land is 2*83 times more 
dense. The vibrations of chords or blades of equal dimen- 
sions, but different material, are, in like times, in frequency 
inversely as the square roots of the densities ; the rotation 
becomes ( v'2‘83) 3 : 1=4*78 : 1. 
Both these and all further developed undulations will be 
represented in land and water, — the one direCtiy, the others 
by induction through the other element. Thus the land 
south to north is 1 : 2*83, and the extreme division of land 
by hemispheres is 2*83 2 : 1. As undulations produce heat 
in air and sounding-board, they produce it in land and 
water. 
Globe II. presents the deutotype. It shows the prototypic 
segment Pr moved to an incline of 23 0 28' to meridian Pr ; 
its basis is tangent to the polar circles in S and M. The 
motion has been reciprocal with the developed inclination of 
the equator on the orbit. 
Segment Ap is equally inclined ; its basis is tangent to 
the polar circles in V and L. The middle segment occupies 
the prototypic position ; it bars equatorial circulation. 
The sum of land inside the segments is to that outside 
^ 4 (2*83) : 1. The land outside is closely around, with the 
exception of the antarCtic section belonging to segment Pr. 
On Globes II. and III. surfaces of land outside correspond 
to equally coloured ocean surfaces inside.
