concurring specially. None of the written requests conform to the rule stated in Lewis v. State, 196 Ga. 755 (3) (27 S. E. 2d, 659), and, for this reason, I concur in headnote 7. However, if they did meet that requirement, the fact that the general charge covered the substance of the requests would not be justification for refusing to charge as requested. Werk v. Big Bunker Hill Mining Corp., 193 Ga. 217 (17 S. E. 2d, 825).
