HAIR (a word See also:common to See also:Teutonic See also:languages)  , the See also:general See also:term for the characteristic outgrowth of the epidermis forming the coat of mammals . The word is also applied by See also:analogy to the filamentous outgrowths from the See also:body of See also:insects, &c., See also:plants, and metaphoiically to anything of like See also:appearance . For anatcmy, &c. of See also:animal See also:hair see SKIN AND EXOSKELETON; See also:FIBRES and allied articles; See also:FuR, and See also:LEATHER . See also:Anthropology.—The human hair has an important See also:place among the See also:physical criteria of See also:race . While its general structure and quantity vary comparatively little, its length in individuals and relatively in the two sexes, its See also:form, its See also:colour, its general consistency and the, appearance under the See also:microscope of its transverse See also:section show persistent See also:differences in the various races . It is the persistence of these differences and specially in regard to its colour and texture, which has given to hair its ethnological importance . So obvious a racial differentiation had naturally See also:long ago attracted the See also:attention of anthropologists . But it was not until the 19th See also:century that microscopic examination showed the profound difference in structure between the hair characteristic of the See also:great divisions of mankind . It was in 1863 that Dr Pruner-See also:Bey read a See also:paper before the See also:Paris Anthropological Society entitled " On the Human Hair as a Race See also:Character, examined by aid of the Microscope." This address established the importance of hair as a racial criterion . He demonstrated that the structure of the hair is threefold: (1) See also:Short and crisp, generally termed " woolly," elliptical or See also:kidney-shaped in section, with no distinguishable medulla or See also:pith . Its colour is almost always See also:jet See also:black, and it is characteristic of all the black races except the Australians and See also:aborigines of See also:India . This type of hair has two varieties .

When the hairs are relatively long and the See also:

spiral of the curls large, the See also:head has the appearance of being completely covered, as with some of the Melanesian races and most of the negroes . See also:Haeckel has called this " eriocomous " or " woolly " proper . In some See also:negroid peoples, however, such as the See also:Hottentots and See also:Bushmen, the hair grows in very short curls with narrow spirals and forms little tufts separated by spaces which appear See also:bare . The head looks as if it were dotted over with See also:pepper-See also:seed, and thus this hair has gained the name of " peppercorn-growth." Haeckel has called it " lophocomous " or " crested." Most negroes have this type of hair in childhood and, even when fully grown, signs of it around the temples . The space between each tuft is not bald, as was at one See also:time generally assumed . The hair grows. uniformly over the head, as in all races . 2 . Straight, lank, long and coarse, See also:round or nearly so in section, with the medulla or pith easily distinguishable, and almost without exception black . This is the hair of the yellow races, the See also:Chinese, See also:Mongols and See also:Indians of the Americas . 3 . Wavy and See also:curly, or smooth and silky, See also:oval in section, with medullary See also:tube but no pith . This is the hair of Europeans, and is mainly See also:fair, though black, See also:brown, red or towy varieties are found .

There is a See also:

fourth type of hair describable as " frizzy." It iseasily distinguishable from the See also:Asiatic and See also:European types, but not from the negroid See also:wool . It is always thick and black, and is characteristic of the Australians, Nubians, and certain of the Mulattos . Generally hair curls in proportion to its flatness . The rounder it is the stiffer and lanker . These extremes are respectively represented by the See also:Papuans and the See also:Japanese . Of all hair the woolly type is found to be the most persistent, as in the See also:case of the Brazilian Cafusos, See also:negro and native hybrids . Quatrefages quotes the case of a triple hybrid, " See also:half negro, See also:quarter See also:Cherokee, quarter See also:English," who had short crisp furry-looking hair . Wavy types of hair vary most in colour: almost the deepest See also:hue of black being found See also:side by side with the most flaxen and towy . Colour varies less in the lank type, and scarcely at all in the woolly . The only important exception to the See also:uniform blackness of the negroid wool is to be found among the Wochuas, a tribe of See also:African pigmies whose hair is described by Wilhelm See also:Junker (Travels in See also:Africa, iii. p . 82) as " of a dark, rusty brown hue." Fair hair in all its shades is frequent among the populations of See also:northern See also:Europe, but much rarer in the See also:south . According to Dr See also:John Beddoe there are sixteen blonds out of every See also:hundred Scotch, thirteen out of every hundred English, and two only out of a hundred Italians .

The percentage of brown hair is 75% among Spaniards, 39 among See also:

French and 16 only in Scandinavia . Among the straight-haired races fair hair is far rarer; it is, however, found among the western Finns . Among those races with frizzy hair, red is almost as See also:common as among those with wavy hair . Red hair, however, is an individual See also:anomaly associated ordinarily with freckles . There are no red-haired races . A certain correlation appears to exist between the nature of hair and its See also:absolute or relative length in the two sexes . Thus straight hair is the longest (Chinese, Red Indians), while woolly is shortest . Wavy hair holds an intermediate position . In the two extremes the difference of length in See also:man and woman is scarcely noticeable . In some lank-haired races, men's tresses are as long as See also:women's, e.g. the Chinese pigtail, and the hair of Redskins which grows to the length sometimes of upwards of 9 ft . In the frizzy-haired peoples, men and women have equally short growths . Bushwomen, the See also:female Hottentot and negresses have hair no longer than men's .

Phoenix-squares

It is only in the wavy, and now and again in the frizzy types, that the difference in the sexes is marked . Among European men the length rarely exceeds 12 to 16 in., while with women the mean length is between 25 and 30 in. and in some cases has been known to reach 6 ft. or more . The growth of hair on the body corresponds in general with that on the head . The hairiest races are the Australians and Tasmanians, whose heads are veritable mops in the thickness and unkempt luxuriance of the locks . Next to them are the See also:

Todas, and other See also:hill-tribesmen of India, and the Hairy See also:Ainu of See also:Japan . Traces, too, of the markedly hairy race, now See also:extinct, supposed to be the ancestor of Toda and Ainu alike, are to be found here and there in Europe, especially among the See also:Russian peasantry . The least hairy peoples are the yellow races, the men often scarcely having rudimentary beards, e.g . Indians of See also:America and the Mongols . Negroid peoples may be said to be intermediate, but usually incline to hairlessness . The wavy-haired populations hold also an intermediate position, but somewhat incline to hairiness . Among negroes especially no See also:rule can be formulated . Bare types such as the Bushmen and western negroes are found contiguous to hairy types such as the inhabitants of Ashantee .

Neither is there any rule as to baldness . From See also:

statistics taken in America it would seem that it is ten times less frequent among negroes than among whites between the ages of See also:thirty-three and See also:forty-five years, and thirty times less between twenty-one and thirty-two years . Among Mulattos it is more frequent than among negroes but less than among whites . It is rarer among Redskins than among negroes . The lanugo or downy hairs, with which the human foetus is covered for some time before See also:birth and which is mostly See also:shed in the womb, and the See also:minute hairs which See also:cover nearly every See also:part of the adult human body, may be regarded as rudimentary remains of a See also:complete hairy covering in the ancestors of mankind . The See also:Pliocene, or at all events See also:Miocene precursor of man, was a furred creature . The See also:discovery of See also:Egyptian mummies six thousand years old or more has proved that this physical criterion remains unchanged, and that it is to-See also:day what it was so many scores of centuries back . Perhaps, then, the See also:primary divisions of mankind were distinguished by hair the same in texture and colour as that which characterizes to-day the great ethnical See also:groups . The wavy type See also:bridges the gulf between the lank and woolly types, all in turn derived from a common hair-covered being . In this connexion it is See also:worth mention, as pointed out by P . Topinard, that though the regions occupied by the negroid races are the See also:habitat of the anthropoid apes, the hair of the latter is real hair, not wool . Further in the eastern section of the dark domain, while the Papuan is still black and See also:dolichocephalic, his presumed See also:pro-genitor, the orang-utan, is See also:brachycephalic with decidedly red hair .

Thus the See also:

white races are seen to come nearest the higher apes in this respect, yellow next, and black farthest removed . No test has proved, on repeated examination, to be a safer one of racial purity than the quality of hair, and Pruner-Bey goes so far as to suggest that " a single hair presenting the See also:average form characteristic of the race might serve to define it." At any See also:rate a hair of an individual bears the See also:stamp of his origin . See Dr Pruner-Bey in Memoires de la societe d'anthropologie, ii . P . A . Brown, See also:Classification of Mankind by the Hair; P . Topinard, L'Homme dans la nature (1891), See also:chap. vi . See also:Commerce.—Hair enters into a considerable variety of manufactures . Bristles are the stout elastic hairs obtained from the backs of certain breeds of pigs . The finest qualities, and the greatest quantities as well, are obtained from See also:Russia, where a variety of See also:pig is reared principally on See also:account of its bristles . The best and most costly bristles are used by shoemakers, secondary qualities being employed for See also:toilet and clothes-brushes, while inferior qualities are worked up into the commoner kinds of brushes used by painters and for many See also:mechanical purposes . For artists' use and for decorative See also:painting, brushes or pencils of hair from the See also:sable, See also:camel, See also:badger, See also:polecat, &c., are prepared .

The hair of various animals which is too short for See also:

spinning into See also:yarn is utilized for the manufacture of See also:felt . For this use the hair of rabbits, See also:hares, beavers and of several other rodents is largely employed, especially in See also:France, in making the finer qualities of felt hats . Cow hair, obtained from tanneries, is used in the preparation of roofing felts, and felt for covering boilers or See also:steam-pipes, and for other similar purposes . It is also largely used by plasterers for binding the See also:mortar of the walls and See also:roofs of houses; and it is to some extent being See also:woven up into coarse friezes, See also:horse-cloths, railway rugs and inferior blankets . The tail hair of oxen is also of value for stuffing cushions and other upholstery See also:work, for which purpose, as well as for making the See also:official wigs of See also:law See also:officers, barristers, &c, the tail and body hair of the See also:yak or See also:Tibet ox is also sometimes imported into Europe . The tail and mane hair of horses is in great demand for various purposes . The long tail hair is especially valuable for See also:weaving into hair-See also:cloth, mane hair and the short tail hair being, on the other See also:hand, See also:principal)y prepared and curled for stuffing the chairs, sofas and couches which are covered with the cloth manufactured from the long hair . The horse hair used in Great See also:Britain is principally obtained from South America, See also:Germany and Russia, and its sorting, cleaning and working up into the various manufactures dependent on the material are See also:industries of some importance . In addition to the purposes already alluded to, horse hair is woven into See also:crinoline for ladies' bonnets, plaited into fishing lines, woven into bags for oil and See also:cider pressers, and into straining cloths for brewers, &c., and for numerous other See also:minor uses . The manufactures which arise in connexion with human hair are more See also:peculiar than important, although occasionally fashions arise which cause a large demand for human hair . The fluctuations of such fashions determine the value of hair; but at all times long tresses are of considerable value . See also:Grey, See also:light, See also:pale and See also:auburn hair are distinguished as extra See also:colours, and command much higher prices than the common shades .

The light-coloured hair is chiefly obtained in Germany and See also:

Austria, and the south of France is the principal source of the darker shades . In the south of France the cultivation and See also:sale of heads of hair by See also:peasant girls is a common practice; and See also:hawkers attend fairs for the See also:special purpose of engaging in this See also:traffic . Hair 5 and even 6 ft. long is sometimes obtained . Scarcely any of the " raw material " is obtained in the See also:United See also:Kingdom except in the form of ladies' " combings." See also:Bleaching of flair by means of peroxide of See also:hydrogen is extensively practised, with the view of obtaining a See also:supply of See also:golden locks, or of preparing white hair for mixing to match grey shades; but in neither case is the result very successful . Human hair is worked up into a great variety of wigs, scalps, artificial fronts, frizzets and curls, all for supplementing the scanty or failing resources of nature . The plaiting of human hair into articles of jewellery, See also:watch-See also:guards, &c., forms a distinct See also:branch of See also:trade . HAIR-TAIL (Trichiurus), a marine See also:fish belonging to the Acanthopterygii scombriformes, with a long See also:band-like body terminating in a See also:thread-like tail, and with strong prominent See also:teeth in both jaws . Several See also:species are known, of which one, common in the tropical See also:Atlantic, not rarely reaches the See also:British Islands .
