“When all the parts are uncovered, and all the fat and cellular tissue has been removed, the member thus prepared must be put into a solution of two ounces of oxymuriate of mercury, to one pint of rectified spirits of wine, and let remain entirely covered with this for at least fifteen days, for it cannot remain too long. A box of oak, painted white and varnished is the best recipient for the limb, whilst in solution; the cover must fit closely, in order to prevent the evaporation of the spirits of wine. “The member must be withdrawn every two or three days, and any remaining cellular tissue is to be removed, and when returned to the tub the part which previously touched the bottom must be placed uppermost. The best thing upon which to place the preparation, when withdrawn from the solution, is a butcher’s tray, after having been well oiled; without this precaution the tray imbibes moisture, from which results a great loss of the solution. When the limb has remained long enough in the solution, it is to be taken out, to be painted and varnished. “Before proceeding to these operations, the member kept in a state of extension, is suspended and dried, then endued with white varnish. On the same day the nerves, the tendons, and tendinous expansions, ought also to be varnished; which must be repeated once a day, for three consecutive days. The fifth day, the tendons, ought to be covered with a layer of yellow varnish, and white paint mixed in equal parts; this operation is to be repeated the seventh, eighth, and ninth day. The nerves, must also be endued, as often as necessary, with a mixture of equal parts of white paint, and white varnish. “As soon as the muscles have become stiff, they may be painted, taking care that the nerves and tendons, are not touched by the paint. Nearly a month after the limb has been withdrawn from the solution, those of the nerves and tendons that are not sufficiently coloured should be repainted and varnished, as often as may be judged necessary. But always allowing a day’s interval between each application of paint and varnish. “These operations being finished, wash lightly the tendons and nerves with boiled flax seed oil; this layer being dry, give a second over the whole limb; finally, several layers of copal varnish will terminate the operation. The first layer of copal varnish to be applied to the arteries with a slight addition of vermillion, and of Prussian blue, for the veins. “In order to preserve the liver, it is necessary first to inject the vena porta and excretory ducts with white varnish, to which has been joined one-fifth of turpentine varnish, and some coloring matter, such as red lead. Then make the coarse injection, after which the liver is to be put into the solution for a least fifteen days; it is not necessary to heat it before injecting. The ligaments are to be prepared in the same manner as the tendons. “We give below the paints, and varnishes, employed in the preceding preparations:
