On the left is shown the line of incisions made through the cartilages from below upward, if a costotome is used;from above downward, if a knife or saw is employed; and also the incision necessary for disarticulating thecla^^cle. When it is not desirable to disarticulate the cla\-icle, the manubrium is separated from the gladiolusat point A, the incision being made from behind. muscles can be further incised, and examined for evidences of bruises,inflammation, and suppuration, and suspicious portions removed formicroscopic study.
