1.--_White Varnish._ ℞. Canada balsam, spirits of turpentine, _a.a._ 3 ℥. Mastic Varnish. 2 ℥. Put the whole in a bottle, and agitate until it is perfectly mixed. 2.--_Mastic Varnish._ ℞. Powdered mastic. 4 ℥. Dissolve in a pint of spirits of turpentine. Agitate daily, until the mastic is dissolved. 3.--_Yellow Varnish._ Infuse one ounce of gum-gutta in powder in eight ounces of spirits of turpentine for fifteen days; then, with equal parts of this clear drawn liquor, Canada balsam, and mastic varnish, form the yellow varnish. 4.--_White Paint._ Three ounces of white lead, and an ounce of spirits of turpentine serves to form it. 5.--_Paint for the muscles._ It is made of Lac, Prussian blue, and white varnish, to which is added one quart of turpentine varnish. 6.--_Red Injection._ ℞. Wax, 4 ℥. Copal varnish, 1/2 ℥. Red lead, 1/2 ℥. Vermillion, 1 ʒ. Melt together. 7.--_Green injection._ ℞. Wax, 4 ℥. Blue dross, 1/2 ℥. Copal varnish, 1/2 ℥. 8.--_Blue injection._ To form this it is only necessary to add to the green injection, half a drachm of powdered Prussian blue.” The advantages of such preparations do not answer, in any degree, to the promises of the title; the artificial preparations of M. Azoux are much more preferable, since his cartons represent the form which the anatomical pieces of Swan have lost by desiccation. SECTION 1.--_Generalities of the operations which precede preservation._ Desiccation and immersion in liquids are the only means of preservation. The choice of subjects which are to serve for these preparations, says M. le Docteur Patissier, is not a matter of indifference. Young subjects, and lean women, are preferable for the nerves and bloodvessels; adults, and thin and dry old men, for the preparation of bones which it is intended to articulate, and which it is desirable to obtain in their greatest degree of development; individuals of an athletic constitution for muscular preparations. The most favourable time for the preparation and preservation of anatomical subjects, is generally during a cold and dry winter, or the ardent heat of summer; the more rapid is the evaporation of the humidity of animal matters, the more sure is their preservation. The method of preservation ought to be preceded by some other operations, such as _dissection_, _maceration_, _injection_, _ablution_, _corrosions_, _ligature of vessels_, _separation and distention of parts_.
