Tweezers

“ If the Hairs of the Eye-Lids or Eye-Brows offend the Eye, they must be pull'd out with a Pair of Tweezers or Nippers; and when any small, hard, and transparent Tumours arise in the Eye-Lids, they are to be open'd, to let out the corrupt Matter. ”

“ The way the cornea seems to fit into the sclerotic is not quite as one is led to believe when told that it fits into the sclerotic much the same way in which a watch crystal fits into a watch. [3] Holding this part of the eye up to a strong light one will see that the sclerotic seems to overlap the cornea in the vertical axis.
By using the tweezers the cornea may be split. Nothing in the way of locating its layers can be recognized, however, unless a section is made for microscopic examination. The epithelial may be scraped off when the cornea is a trifle dry. ”

“ Severe inflammation may be excited, and serious injury done, by rash attempts to seize a foreign body in the ear, with a forceps or tweezers, or trying to pick it out with a pin or needle, or with an ear scoop. ”

“ These natives do not tolerate hair on the body and pull it out or shave it off. The men even remove the hair at the edge of the scalp all around the head, letting the remainder attain a growth of about sixty centimetres, and this is tucked up in a coil under the cap. The hair of eyebrows and eyelids is removed with great care. The women perform this operation, and tweezers made for the purpose are usually seen among the ornaments that hang from the tops of their hats. ”

“ The hair itself arises from a cornification of the cells of the axis of one of the above processes; and is invested by a sheath similarly formed from the more superficial epidermic cells. A small papilla of the dermis grows into the inner end of the epidermic process when the hair is first formed. The first trace of the hair appears close to this papilla, but soon increases in length, and when the end of the hair projects from the surface, the original solid process of the epidermis becomes converted into an open pit, the lumen of which is filled by the root of the hair. ”

“ The operators appear to rely largely on manual dexterity, and to aim at completing the procedure in a minimum of time. The needle or thorn is thrust suddenly through the cornea, and on through the pupil or iris, into or on to the periphery of the lens. The next movement, which appears to follow the first so rapidly as practically to melt into it, is that of depression or reclination. In this, the spot where the cornea grasps the shaft of the needle serves as a fulcrum. ”

“ Now comes the really fascinating part of the work. Thread a wool needle with scarlet Berlin and with this work on the “head” with a few bold stitches eye-brows, nose and open mouth. I generally found three stitches enough for one eye-brow, and the same number for the nose; but here again individual discretion comes into play.
Thread another needle with white Berlin and supply the aforesaid open mouth with pearly teeth which need not by any means be regular; indeed you can give “Fuzzy-Wuzzy” an endless variety of expressions according to the direction of your stitches. ”

“ The denudation, which may be made with a knife or with scissors curved on the flat, should be begun upon the lower lip. The tissue to be removed may first be marked out with the knife. The tissue to either side of the old external os is seized with a tenaculum or with toothed tissue-forceps, and a strip is elevated by an incision extending into the angle of the tear. A corresponding opposite portion of tissue on the anterior lip is then seized in a similar manner, and a similar strip of tissue is excised, meeting and joining the strip first raised in the angle of the tear. ”

“ It is on these scales that the lustre or gloss of the hair depends. Since lustre is due to the unbroken reflection of light from the surface of the hair, the smoother the surface, the glossier it will appear. When the scales of the cuticle are irregular and uneven, the surface of the hair will not be uniform and [24] smooth, and the light reflected from it will be broken and scattered, and consequently the hair will not possess a high degree of lustre. ”

“ Thus the sudoriforous, or sweat glands, may be found in the sole of the foot, whilst the sebaceous glands are to be sought in the skin of the nose. The papillæ are well represented at the tips of the fingers, [17] whilst the structure of the shaft of the hair, together with that of the follicle within which its root is enclosed, as also the muscles by which it is moved, are to be studied in sections of skin from the scalp or other suitable locality. ”

“ We will now briefly state that the coats of this organ are constituted of a fibrous membrane, T (fig. 95) , termed sclerotic, which is opaque, except in the anterior portion of the eye, where it forms the transparent cornea. The crystalline, C, enshrined behind the cornea, is the convergent lens of the inner chamber; it is covered with a transparent membrane, or capsule, and is bathed in two fluids, the aqueous humour, between the crystalline humour and the cornea, and the vitreous body, a gelatinous humour lodged between the crystalline and the back of the eye. ”

“ On the other hand, he has endeavoured to conceal some of these stains upon the felt by daubing them with ink, which is a sign that he has not entirely lost his self-respect.”
“Your reasoning is certainly plausible.”
“The further points, that he is middle-aged, that his hair is grizzled, that it has been recently cut, and that he uses lime-cream, are all to be gathered from a close examination of the lower part of the lining. The lens discloses a large number of hair-ends, clean cut by the scissors of the barber. They all appear to be adhesive, and there is a distinct odour of lime-cream. ”

“ The HAIRS are appendages of the skin, and, like the cuticle, they are a product of secretion. They have no blood-vessels or nerves, and, consequently, no vitality. The hairs take their origin from the cellular membrane, in the form of bulbs. Each hair is enclosed beneath the surface by a vascular secretory follicle, which regulates its form during growth. In texture, it is dense, and homogeneous toward the circumference, and porous and cellular in the centre, like the pith of a plant. ”

“ The hair is worn very long, rolled into little curls and plentifully oiled. A most peculiar deformation is applied to the nose and results in extreme ugliness: the septum is perforated, and instead of merely inserting a stick, a springy spiral is used, which presses the nose upward and forward, so that in time it develops into an immense, shapeless lump, as if numberless wasps had stung it. ”

“ Fig. 51. Fine drawing.
Use as fine a needle as possible and thread it with hair, instead of silk, or any other kind of fibre. Red and white hair is the strongest, and stronger than the ravellings of the stuff. Of course the hair has first to be carefully cleansed from grease. Pare the edges of the rent, on the right sides, quite clean and even, with a razor, so that both rent and stitches may be lost in the hairy surface of the cloth. Scissors do not cut so closely, and are liable moreover, to disturb the nap, and render the darn more visible. ”

“ The epidermal surface of such flap is made to form the inner or mucous surface of the repaired cheek (see Fig. 265) , while its external surface and the secondary wound are covered with Thiersch grafts, at one and the same sitting.
The only difficulty experienced in the case with men is that the bearded surface of this inturned flap offers considerable discomfort to the patient, although in the majority of cases the skin thus inverted soon takes on the appearance of the mucosa, the objectionable hairs falling out and the hair follicles becoming obliterated. ”

“ The blood supply for the hair is very abundant. There is a complete system of blood vessels encircling every one of the follicles, and besides this each papilla has a special distribution of blood to itself. That part of the hair lying within the hair-follicle is called the root. The lower end of the root, which swells out into a knob, named the bulb, is concave in shape underneath, so as to fit on top of the projecting papilla. The shaft is the long stem of the hair, while its extreme end is termed the point. ”

“ Continue cutting through the sclerotic and all underlying tissues, stopping at the corneo-scleral junction, but do not, during this procedure, [88] even touch the lens. After the eye has been thus partly separated into, as nearly as possible, two equal parts, lay it down upon the cornea, and, holding the razor blade in the forefingers and thumbs of both hands, cut the lens in two by forcing the blade down through it. (Fig. 42.) Partly open the cut eye to allow one jaw of the large scissors to enter, turn the eye over so the cornea will rest on that [89] jaw, and then cut through the cornea. ”

“ The layer of epidermis or skin which lies immediately above the supra-œsophageal ganglia becomes gradually converted into the refractive media of the crustacean eye. A cuticle which lies on its surface forms the peculiar facets on the surface of the eye, which are known as the corneal lenses, while the cells of the epidermis give rise to lens-like bodies known as the crystalline cones. ”

“ Wrinkles must be painted across the forehead, furrows down the cheeks, downward lines from the corners of the mouth, and (very important) three or four heavy wrinkles painted around the neck to give it the shriveled appearance common to old age. The hollow over the upper lip should be darkened, and also the hollow under the lower lip. ”

“ A third view is that the filaments from the hair cells, rather than the basilar membrane, respond to the vibrations and in turn stimulate the terminations of the nerve fibers.
Fig. 155—Diagram showing how wax may plug the auditory canal and cause deafness. Hygiene of the Ear.—The ear, being a delicate organ, is frequently injured by careless or rough treatment. The removal of the ear wax by the insertion of pointed instruments has been found to interfere with the natural method of discharge and to irritate the membrane. It should never be practiced. ”

“ The tusks appear externally to the mouth, the form of the upper lip being modified to allow of their protrusion, but are much less developed in females than in males. The teeth of the molar series gradually increase in size and complexity from first to last, and are arranged in contiguous series, except that the first lower premolar is separated by an interval from the second. ”

“ If the deep shadows show a white margin and are difficult to ink up, the skin has been exposed under the negative for too long a time; and if “smashing” down does not remedy the defect, the only chance of saving it will be to allow the skin to get thoroughly dry, and then (say the next day) to soak it up again for an hour.
Spots on the margin of the print may be removed by carefully painting them over with a camel’s-hair brush charged with dilute cyanide of potassium, carefully washing afterward to prevent spreading. ”

“ The hair upon the scalp is thicker and longer, the eyes remain closed, and very delicate hairs may be seen upon the margins of the eye-lids and upon the eye-brows. The nails are solid, the scrotum small and empty, the surface of the skin appears wrinkled but the dermis may be distinguished from the epidermis. ”

“ In some crania, there are tusks and incisors in both jaws, but in others neither, or the former only. The tusks scarce project beyond the jaw, probably never beyond the lip. The absence of the teeth in some may be owing to age. A single spiraculum opens near the top of the head. ”

“ In such faces the tubercles arrange themselves in parallel series above the brows down to the nose, over the cheeks, lips and chin, and as a result of the infiltration and development of the conditions the brows deeply over-hang; the globes of the eyes, and the ears, are so studded with tubercular masses as to stand out from the side of the head. The trunk and extremities, including the palms of the hands and soles of the feet, are then usually involved to a less degree. ”

“ Unimportant irritations, which on the surface of the body are not noticed, seriously affect the cornea.
Let us now notice the second coat, the choroid. This we compared to the black coating of paint in the camera-obscura. Thinking of the dazzling and delusive visions which are a consequence of the gradual consuming away of the pigment in the choroid, or which accompany the entire want of it, as with the albinos, we cannot doubt that one essential design of this tissue is to intercept the scattered rays. ”

“ Hence the naked savage of New South Wales pierces the septum of his nose, through which he runs a stick or a bone, and scarifies his body, the charms of which increase in proportion to the number and magnitude of seams by which it is distinguished. The operation is performed by making two longitudinal incisions with a sharpened shell, and afterwards pinching up with the nails the intermediate space of skin and flesh, which thereby becomes considerably elevated and forms a prominence as thick as a man's finger. No doubt but pain must be severely felt until the wound be healed. ”

“ The cuticle, epidermis, or scarf-skin, as it is indifferently termed, is formed of cells or scales, much flattened and horny in the upper layers, rounder and plumper below. The true skin, or “cutis,” is fibrous in structure, and lies immediately beneath, the two together constituting the skin, properly so called. Beneath lies a layer of tissue filled with fatty globules, and containing the glands by which the perspiration is secreted. ”

“ Care must be taken not to lacerate the anterior surface of the lens when the iris is drawn back by the pins.
Putting the pins into the cornea, and using them as levers with the point of entrance in the cornea as a fulcrum, will pucker the cornea considerably, and a good clear fundus cannot be obtained. This is easily overcome. Simply gather up all the tissues surrounding the eye, force them backward, and hold them firmly with the fingers of the left hand. ”
