Its time in transit is of approximately two and one-fifth seconds. Shooting straight up, such an arrow goes about three hundred and fifty feet high, and requires eight seconds for the round trip. This test was made by shooting arrows over very tall sequoia trees, of known height. The striking force of a one-ounce arrow shot from a seventy-five pound bow at ten yards, is twenty-five foot pounds.
The reader will now, of course, see that what is true of the motion of free bodies, must also be true of the motion of suspended ones, since the same terrestrial attraction causes both. There is no reason why the two-pound weight in the experiment should vibrate quicker than the one-pound weight, just as there is no reason why a two-ounce bullet should fall quicker than a one-ounce bullet.
This may be regarded as a metastic, or shifting disease; first one part, and then another, seems to be affected. Treatment. Mild purgatives should be used; one-half-ounce doses of colchicum-root pulverized will be found useful; one-ounce balls of pine-tar may also be given with advantage.
