Famous quotes containing the words percussion and/or notes:
“We got our new rifled muskets this morning. They are mostly old muskets, many of them used, altered from flint-lock to percussion ... but the power of the gun was fully as great as represented. The ball at one-fourth mile passed through the largest rails; at one-half mile almost the same.... I think it an excellent arm.”
—Rutherford Birchard Hayes (1822–1893)
“The germ of violence is laid bare in the child abuser by the sheer accident of his individual experience ... in a word, to a greater degree than we like to admit, we are all potential child abusers.”
