On the value, in a scientific point of view, of the physical signs derived from auscultation and percussion in cases like this, it is scarcely necessary to comment; since it is evident that, although the general history, when duly collected*and considered, was highly significant, it would not have been sufficient, without the aid of these more precise indications, to ascertain the actual condition of the internal organs; namely, the perfectly healthy state of the right lung, the thoroughly disorganized state of the left lung, and the accumulation of a large quantity of liquid in the left pleural sac.
