Various methods have been attempted for preserving birds from putrefaction, so as to retain their natural form and position, as well as the beauty of their colours and plumage. A good antiseptic for animal substances has been much inquired after, as, for want of it, many curious animals, and birds particularly, from foreign parts, entirely miscarry, and others of the finest plumage are devoured by insects. The following improved method by Dr. Lettsom seems to be the least troublesome, and the most complete. After opening the bird by a longitudinal incision from the breast to the vent, dissecting the fleshy parts from the bones, and removing the entrails, eyes, tongue, and brains, (which in large birds may be extracted through the eye-holes with a surgeon’s directar,) the cavities and inside of the skin are to be sprinkled with the powders mentioned below. Glass eyes, which are preferable to wax, are then to be inserted, and the head stuffed with cotton or tow, and a wire is to be passed down the throat through one of the nostrils, and fixed on the breast bone. Wires also to be introduced through the feet, up the legs and thighs, and inserted into the same bone; next fill the body with cotton to its natural size, and sew the skin over it; the attitude is lastly to be attended to, and whatever position the subject is placed in to dry, it will be retained afterwards. The dyeing compound is as follows:— Corrosive sublimate ¼ lb. Saltpetre, prepared or burnt ½ lb. Alum, burnt ¼ lb. Flowers of sulphur ½ lb. Camphor ¼ lb. Black pepper 1 lb. Tobacco, ground coarse 1 lb.
