The main-incision is then closed by a continuous base-ball stitch, using a stout linen pack-thread and a rather large, slightly curved needle. The first stitch begins in the middle-line about 1 cm. above the beginning of the main-incision, the needle being introduced from below through the incision, and the thread secured at its end by a knot. The stitches are then made about 5-7 mm. apart, the needle each time being pushed through the skin from the inside, so that it comes through the skin about 5 mm. on either side of the incision, alternately to the left and right. The thread is kept tightly pulled, and as perfect coaptation as possible is secured. At the end of the incision the thread is secured by a knot before it is cut. Collodion or surgeon’s plaster may then be used to cover the entire incision. All other skin-incisions are sewed up in the same manner. When the testes and the body of the penis have been removed, it may be necessary under certain conditions to restore the form of these parts before the main-incision is closed. Cotton wads may be used for this purpose. When all incisions are finally closed the cadaver is carefully washed and all blood-stains and discolorations removed. When formalin has been used as an injection-fluid blood spilled upon the skin may produce a brownish stain that is removed with difficulty. Corn-meal or hand-sapolio may be used to remove such stains. After the cadaver has been thoroughly washed, it is dried, and can then be turned over to the undertaker. CHAPTER XVI.
