A. The concussion or violent agitation of the water may loosen a body slightly held at the bottom, when, if specifically lighter than water, it will rise.
Q. In “Recreations in Astronomy,” p. 163, it is said 192 asteroides have been discovered, with diameters from 20 to 400 miles; and on the next page it is “estimated” that if all these were put into one planet, it would not be over 400 miles in diameter. How can that be?
A. Allowing, as the author does, that the density of the masses remains the same, it would, of course, be impossible. We have not the means at hand to either verify or correct the diameters given, and can not locate the error.
