An Internal Rebel Bullet. - We were shown, by Wm T. Marks, a gentleman just from the army of the Potomac, a bullet invented by the rebels. It is a conical ball, screwed on to a chamber, at the bottom of which a percussion cap is fixed, surrounded with powder. A slender bolt or needle runs through the solid ball. This needle has a flat head on the outside of the bullet, and the needle works loose, so that when it strikes any hard substance, like the bone, it is driven against the cap and explodes it. -Phila. Inquirer. We learn that a quantity of musket balls, of a similar pattern, were discovered in this place recently.
