Shaping.—Since these directions will be used chiefly in preparing the skins of deer, antelope, and kindred ruminants, the accompanying illustration (Fig. 8) is given to show how such skins should be made up when they are to be preserved dry, either for study or for mounting. It is best to defer folding up a skin until it is partially dry and has begun to stiffen a little.

Special and Exceptional Directions.—Apes and Monkeys.—If you are in the jungle, the chances are that you will have no plaster Paris with which to make casts, in which case you must make the sketching-pencil and tape-measure do double duty. With such a wonderful and characteristic form as a gorilla, chimpanzee, or orang-utan, you cannot study it too much, unless you study it until the skin spoils. Above all things, study every feature of the face, and also its expression, so that you can make a copy of it two years afterward which shall be both mathematically and artistically correct. If you have plaster Paris, fail not to take a mould of the face, and also of one hand and foot, so that later you can make casts. The same advice applies to the great baboons with their fearful and wonderful faces and ischial callosities, some of them gotten up with all the colors of the rainbow, and far more brilliancy. Remember that when the skin dries all those colors totally disappear, and the skin turns to the color of parchment. Therefore, out with your box of colors at once, and make a color-sketch of the face. If you have skill but no colors, or colors with no skill, then out with your "Ridgway's Nomenclature of Colors," make a large diagram or sketch of the head, and mark the names of the respective colors upon it. Whenever the skin of any animal has any noticeable color, record the fact in as definite terms as possible.
All the great anthropoid apes should have the opening-cut for the body made along the middle of the back, up to the back of the head, instead of along the abdomen and breast, which are generally but thinly haired, and on the throat are quite naked. By doing this, the sewed-up seam comes at the back of the mounted specimen, in the hair, and out of sight. With adult specimens of the gorilla, chimpanzee, and orang the skeleton is quite as valuable as the skin, therefore every bone must come forth and be carefully preserved. Skinning the fingers is a tedious task, and one which requires some skill, especially when it comes to working the end off so that the nail is left in its place in the skin, and without mutilation. But when the value of a skin and skeleton runs up into hundreds of dollars, you can well afford to spend a whole hour in skinning a hand, if you cannot do it in less time. The opening cuts for the hand and foot of any ape or monkey are to be made as shown by the dotted lines in the accompanying sketch of the foot of an orang-utan (Fig. 9). This is necessary even in skinning small quadrumanes which are to retain their leg bones, because the skin of each finger must be separated from the bone so that the preservative powder or liquid can get at the inside of it.

The Eyes and Nose.—Be exceedingly careful in skinning the face. The eyes are deeply sunken in their sockets, and if you are not very careful your knife will make an ugly gash at the corner of the eye before you know it. A finger held in between the lids against the eyeball will be a safe guide. Of course, you will cut the lips away at the gum, and split them open afterward from the inside to remove the flesh. And, of course, the proboscis of the baboon and the long-nosed monkey of Borneo must be skinned out quite to the tip while the specimen is fresh, or it will dry up horribly.
The Ear.—The ear of a quadrumane, especially that of a chimpanzee, because of its great size, is a very miserable part to preserve, unless you have a salt-and-alum bath at hand. If the cartilage is entirely skinned out—itself a difficult thing to do—it will afterward be almost a practical impossibility to give the ear its proper shape. Therefore the cartilage must remain. The skin can be loosened from the cartilage at the back of the ear, however, which is a great gain. Do this, and insert a good quantity of powdered alum. Then paint the whole ear over on both sides with arsenical soap, and put on all the powdered alum that will stick—unless the skin is to go in the bath. In that case treat each ear to a little strong alum water for an hour or so.
