Papa said he had adopted Doctor Sylvester's mode of proceeding, which is that advocated by the Royal Humane Society.  The advantages of it are that inspiration may be made to precede expiration.  The expansion of the throat is artificially ensured.  The patient is not likely to be injured by the manipulation, and the contents of the stomach cannot pass into the wind-pipe, while the tongue is prevented from obstructing inspiration.  Both sides of the chest are thus equally inflated, and a larger amount of air is inspired than by other methods.  Of course, where medical men with apparatus are at hand, other plans may be adopted; but papa said he had seen several persons treated as Jack had been, apparently much farther gone, but who yet had completely recovered.
