    perceive any change induced by a fracture. Whenever, in consequence of a blow or a fall, a member becomes concave in a part where it is naturally convex or straight, and vice versa; this change of form and direction must be at- tributed to a fracture, with derangement of the fraements. The internal side of the great toe, when the foot bears on an horizontal plane, ought to be in the same perpendicular line with the inside of the patella : nothing but a fracture of both bones of the leg can change this relative position of these parts. The relative position of the condyles of the humerus, and of the apophy- ses of the olecranon, indicate in like manner the luxation or fracture of the humerus. The de- rangement of the fragments may sometimes be perceived by moving the fingers on the parts of the bone which are least covered by the intega- raents. This sign is easily detected in the fractures of bones which are not surrounded by much f]esh, but which lie almost immediately under the skin : such, for example, are those of the lower jaw and the clavicles. But of all the symptoms, crepitation is the most general and distinctive; and can never be con- founded by an experienced practitioner with the noise produced by emphysema, by an aqueous effusion.
