Practical Taxidermy Part 12

Spirits of naphtha, 0.5 pint.

Place them in a bottle in a warm situation on a closed stove, or in a vessel containing hot water. Be careful of fire. The edges of bones or undersides of fossils are smeared with this, tied with string, and left for a day or so to unite.

The reader has now a repertoire of poisonous and harmless preparations from which he may choose. As for myself, for the preservation of birds, I pin my faith to formula No. 4, viz, my Preservative Soap for the inside of the skin, and a wash of benzoline or turpentine liberally applied from time to time--say twice a year--to the outside of all uncased or exposed specimens. This, it will be seen, entirely does away with the use of any poison, and yet is proved to be of the highest efficacy.

For those who do not object to expense nor to the use of a poisonous preparation, a wash of Waterton's Solution (No. 5), or the sulphuric ether preparation (No. 18), can be subst.i.tuted for benzoline or turpentine. I mention the expense, because only rectified spirits of wine, or pure sulphuric ether, will do for birds; the methylated spirit, though of service for washing over most subjects, is not so good when applied to the delicate feathers of birds, as it leaves on drying a certain impure residuum behind it.

For mammals I recommend my formula of burnt alum and saltpetre (No.

9), followed by a wash of benzoline or turpentine twice a year, or by any one of the mercurial preparations given.

On a retrospect of this chapter it will, I think, be admitted that, if I am adverse to the use of any poisonous preparations in taxidermy, I at least point out the why and wherefore, as also an alternative course, showing at the same time the benefits and defects of both systems. I now, therefore, leave the amateur to choose for himself--bearing in mind the time-honoured aphorism, chacun a son got.

CHAPTER V.

SKINNING AND PRESERVING BIRDS.

IN order that this shall be a thoroughly practical chapter, I will, in my method of working, copy the admirable plan of my old sporting favourite, Col. Hawker, who, when wishing to note down some difficult point, was in the habit of doing with his own hands all things pertaining to the matter at issue, because, as he said, he might not make mistakes when subsequently writing upon knotty subjects intended for his readers' consideration.

I have, therefore, specially procured a starling, as I consider this bird the very best for the amateur's purpose, not only on account of the toughness of the skin, but also because, being a medium-sized bird, it presents no difficult points in skinning, and with this bird before me I shall minutely instruct my pupil, pointing out each step that has to be taken and each difficulty that is likely to arise.

As I shall have occasion constantly to refer to the various parts of the skeleton, I now give an engraving of that of the Peregrine Falcon, in order to help my explanations in the future (see Plate II.).

Having placed ready for use the skinning knife (see Fig. 11), the scissors (Fig. 14), and the cobbler's crooked awl in handle, a pot of preservative mixture, some cotton wool or wadding, some tow, and a needle and thread; lay the starling on its back on a piece of clean paper, the head of the bird pointing from the operator; then seize the bird by the sides of the head with the first two fingers and thumb of the left hand in opposition, the awl held in the palm of the right hand, and a piece of wool between the right-hand finger and thumb; then insert the point of the awl between the upper and lower mandibles, and, having opened them, keep them open with the first finger of the right hand, removing the piece of wool which should have been previously placed there by the sportsman (see instructions re shot birds, at end of Chapter II.). Replacing it with the fresh piece of wool held in readiness, plug the nostrils in the same manner.

As even this simple operation will have somewhat disarranged the feathers of the head and neck, smooth them down with the fingers, taking care, however, not to stretch the neck in doing so. The next operation is to hold the left-hand wing with the left hand, and with the fingers of the right hand break or disjoint the bone of the wing as close to the body as possible, i.e, across the "humerus" (E) (in the case of large birds, or for some special purpose, this bone is often left intact, but the amateur will be puzzled how to subsequently arrange it in the skin if unbroken). Repeat this on the other wing.

For those whose fingers are not strong enough to do this effectually, I recommend a small pair of flat-nosed pliers, some sizes larger than the "feather pliers" (Fig. 19).

Large birds may have their wings broken at the humeri (E) by striking them with a stick or hammer in such a manner as not to break nor seriously disarrange the feathers; the largest-sized pliers (Fig. 16) may also be used for this purpose, but in that case a piece of clean rag should be folded in the jaws of the pliers so as to envelope the upper and under surface of the wing, in order to protect the feathers from injury. Practice will, however, point out the best method of doing this. Next take hold of the legs with the fingers and gently twist them out of joint at the junction of the tibia and femur.

Now, keeping the head of the bird toward you, part the feathers away from each side of the sternum or breast-bone; then with the knife held short in the hand, the point placed exactly in the centre of the bird (calculating from the bill to the tip of the tail), make the first incision just on the right side of the breast bone down to the vent, taking care not to cut so deeply as to expose the intestines. Now turn the bill towards your right, and gently lay hold of the cut edge of the skin, which you see shining whitely in front of you; then with the point of the knife--the cutting edge kept on the flesh--gently loosen the skin above, below, and downwards. Completely reverse the bird, and repeat this for the other side.

At this stage the body may be held down, with the knife pressed on the side of the breast bone, and thus the two first fingers of the left hand may be advantageously employed--but in a very gentle manner--to loosen the skin around the upper part of the breast-bone from the inside, while the thumb regulates the pull from the outside. All must be done with the feathers kept as much away from the flesh as possible.

Fig. 22--Starling--Showing Position of First Incision and the Commencement of the Removal of the Skin.

Fig. 22 shows the appearance which the specimen should now present.

The skin being, as it were, nicely "persuaded" from the flesh (more being done by pushing than by pulling), the legs begin to appear. Take hold of the one nearest to you with the right hand, at the same time inserting the fingers of the left inside the skin; then, by gently pushing up with the right hand, free the legs sufficiently to show the second joint, where it has been previously twisted or broken.

Laying down the knife, and picking up the scissors, force their point underneath the joint, marked P in Plate II, and cut it completely off; it should then be clear of the flesh, showing the skin on either side as if it were a stocking turned inside out. Pull it gently by the claw back into its proper position, and there leave it, and do the same by the other leg, turning the bird again for that, purpose.

Both the legs should now be entirely free, not holding to the body at any point. Taking up the knife again, carefully work with it down toward the tail, and as far round the back as you can get with safety.

Now let the bird rest on its head, as it were, with the beak from you, and, placing the fingers with the thumb on the back (which is now underneath), the middle finger on the root of the tail inside, flanked by the first and third fingers keeping down the skin on either side, cautiously insert the knife through the skin of the vent, and cut that free, cutting upward in a slanting direction; having done this, carefully cut away on the root of the tail, at the same time freeing it wherever it sticks; then, when nothing but one bone, that is to say, the last caudal vertebra, holds it, slip the knife underneath and cut with a drawing motion upward. The tail is now entirely separated from the body.

Now advance the fingers of the left hand and seize the bottom part of the loosened body with the right hand, and by pushing with the finger-nails, and occasionally using the knife where the tendons hold the skin, gradually work up the back, turning it round and round, and working very carefully until the place where the wings have been previously broken is arrived at. Again lay down the knife, and taking up the scissors, cut the wing nearest to you away from the skin; do the same with the other side; and now the only thing which holds skin and body together is the neck. Taking the whole of the body in the hand, proceed with the fingers of the other (using no knife) to gradually cause the skin to leave its attachment at the neck. With care work over the head by the same means, and here progress is stopped by the skin being held on either side of the face by a little membrane; this is the inner skin of the ears.

Regaining the knife, slip the point underneath, and gradually lift them out, cutting towards the flesh and not towards the skin. This done, the skin will appear darker, immediately above this point. These are the eyes; carefully cut on top of them with a very gentle motion, until they are skinned to where only a very thin membrane hides them from view; arrived at this, the knife-point must be pushed gently underneath, and an upward cut made, which, if carefully done, entirely severs the eyelids from the retaining membrane. The exact point shown in Fig. 23 is now reached.

Fig. 23--Skin of Bird Turned Ready for Severance from Body

After this sever the skull from the neck at the point where the dotted lines A--B are shown in the drawing. This exposes the brain without cutting off too much at the base of the cranium, the shape of which is wanted for subsequent operations. After the body is completely severed, proceed to pull the tongue out (unless wanted for show) by placing the knife on the other aside of it in opposition to the thumb, give a smart pull, keeping an even pressure on, and the tongue will come out with little or no difficulty.

Next enlarge the orifice at the back of the head by cutting a triangular piece out towards the palate or roof of the mouth, scooping the brains out with the point of the knife, having a small piece of paper in readiness to receive them. During this operation hold the beak of the bird through the skin of the neck by the two first fingers, and thumb, the latter being uppermost, the other fingers being employed in keeping the remainder of the skin with the feathers out of harm's way.

Inserting the point of the knife at the back of the eye, place the thumb on the eyeball and gently pull it out, taking care not to let the point of the knife cut upward so as to burst the eye, or the effect will be to liberate the dark-coloured pigment or the vitreous humour, and thus wet or stain the feathers. Having done all this, there will still remain some little flesh at the back of the eye and the junction of the mandibles, and this must be carefully cut away so as not to dis-articulate the latter. The Preservative Paste now comes into requisition, and with this the skull and orbits are well painted inside and out. A little tow, previously chopped by the medium of a sharp pair of scissors, is now pushed into the empty skull, with the "stuffing iron," which is a small piece of thick wire (see Fig. 21).

For large birds the tow forceps (see Fig. 20) may be conveniently used.

Having neatly filled the head with the tow, proceed to put a small piece of cotton wadding in each orbit. (Note, be careful that tow only is pushed into the head, as if never so small a piece of wadding gets into the cavity of the head it will effectually prevent any subsequent mounting of the specimen, as, singular though it may appear, a small piece of wadding is more than a match for a pointed wire.)

During all this time the neck must be kept as short and as little stretched as possible. In some birds a line of fat will be observed extending from the neck to the back or even to the breast, which must be as carefully as possible sc.r.a.ped off the skin by using the edge of the knife, guided by the thumb. Having done this, paint the neck only with the preservative, and lay the skin on the paper, back upward and tail from you; the under part of the head in this position points upward.

Place the thumbs of both hands, their nails touching each other, at the back of the head with the first two fingers of each hand placed in this wise: forefingers along the side of the face, second fingers underneath on the top of the skin of the head; then, by gently pushing with the thumbs and pulling or scratching, as it were, with the other fingers, gradually force the head through until the mandibles appear, as also the eyelids. Let go with the right hand, still keeping the thumb of the left pressing against the head; and, by gently working with the two first fingers of the left hand outside the feathers, and by pulling the beak upward and toward you with the right, the bird is returned to the position shown in Fig. 22.

As the bird now lies, it is optional whether the flesh is cleaned away from the root of the tail first or from the legs and wings. I will, however, in this case take the wing on my right. Place the right hand underneath, lift the wing as far up into the skin as possible, and by holding it tightly in that position with the finger and thumb of the left hand, a ridge of skin becomes visible, running down each side, and framing in, as it were, a little oval-shaped piece of flesh, i.e.
