2. _Length of tail, from root to end of vertebræ._
3. _Length of hind foot._ Bend the heel at a right angle, and measure from the outer extremity of the angle to the tip end of the longest toe, including the nail.
4. _Height at shoulders_, if the animal be not too small. To take this, lay the animal on its right side, then, as nearly as you can, place the right leg and foot in the position they would assume if the animal were standing erect (the sole of the foot must be parallel to the axis of the body), and measure in a straight line from the bottom of the heel to the top of the shoulders. Record, also,
5. _The color of the eyes, and the other soft parts._
Do not forget what has been said in Chapter III. about outlines and sketches. On one corner of the outline-sheet we record the name of the specimen, locality, date, sex, measurements, color of eyes, lips, feet, etc. It takes but a few moments' time, and the result is a complete and accurate record of what the animal was in the flesh. These sheets are numbered and filed away, the skin is numbered and put in the bath, and even though it be not until five years later that we are ready to mount it, we can tell as accurately what the animal was like as if it had been received only the previous day. If the specimen is a baboon, for example, with several colors on its face, it was for years my practice to make a rough sketch of the face and put upon it the various colors that belong there, in oil-colors, usually, though sometimes with water-colors. It was also my custom to spend half an hour or so in taking a mould, and making a quick cast in plaster Paris of the face of every monkey or baboon which came to me, unless I already had one which would answer as a model to copy in finishing the face.
SKINNING SMALL QUADRUPEDS.--Lay the animal flat upon its back, head to your right. Hold your knife with the edge up, and push the point through the skin of the throat, precisely in the middle of the neck. Now push the point of the knife forward under the skin, between it and the flesh, and divide the skin in a straight, clean cut along the middle of the neck, breast, and body, quite to the base of the tail. If the animal has a large, fleshy tail, like a dog or raccoon, it must be slit open along the under side (without cutting the hair) for its entire length, except an inch or two at the base. If the tail is small, slender, or bony, like that of a squirrel or a rat, it can usually be slipped out of the skin by pulling the bony part between two sticks held close together against the skin of the tail.
