I.—Tne Rotations oF THE PLANETS, 
In 1849, a very simple formula connecting the rotations of 
the planets, and harmonizing in a remarkable manner with the 
elements of the solar system so far as known, was communica- _ 
ted to the American Association for the Advancement of Science.

If the solar system has resulted, as was supposed by Laplace, 
from the gradual contraction of a rotating nebulous spheroid, 
what was probably the physical constitution of the abandoned 
uatorial rings in the first stages of their separate existence ? 
The celebrated author of the nebular hypothesis supposed each 
of the rings in which the Se a originated to have re- 
volved, during an indefinite period before its dissolution, as one — 
continuous mass. ‘These zones,” he remarks, ‘“ ought, accord- 
i to form by their condensation and by the
