PRESS OF THE NEW ERA PRINTING COMPANY LANCA51 ER, PA. 19 10 EXCHANGE o [Reprinted from the AMERICAN ANTHROPOLOGIST, Vol. 18, No. 2, April-June, 1916] SKELETAL MEASUREMENTS AND OBSERVATIONS OF THE POINT BARROW ESKIMO WITH COMPARI SONS WITH OTHER ESKIMO GROUPS BY ERNEST WILLIAM HAWKES PREFACE PR the past six years the author has made an intensive study of that very interesting people, the Eskimo. Between three and four years of this time have been spent in work among them, in Bering strait and on the Yukon river in Alaska/, and in Labrador and Hudson bay in the east. Although the author has been principally interested in the ingenious culture of these masters of environment, the opportunity for physical observation has not been neglected. Consequently, when an opportunity offered for filling in a gap in the physical anthropology of the Eskimo, through the presence of a very complete and fair-sized skeletal collection from Point Barrow, Alaska, in the Wistar Institute of Anatomy in Philadelphia, which had been left untouched since its collection in 1898, the author was very glad to supplement his information on this subject. A year was spent on the material with the following results. The collection was measured and its general characteristics out lined and comparisons instituted with other Eskimo tribes. Later, the comparison may be extended to include the Indians bordering on the Eskimo. The author wishes to thank the University of Pennsylvania for its cordial support in this work, and the Director of the Wistar Insti tute of Anatomy for generous accommodations during the pursuit of the same. He also wishes to acknowledge his indebtedness to Mr. Ralph Linton for the measurements of the long bones, and much helpful assistance in the completion of the work. 203 448351 204 AMERICAN ANTHROPOLOGIST [N. s., 18, 1916 INTRODUCTION ^ The ^Eskimo present the unique spectacle of a people extending for five thousand miles across the entire northern border of a con tinent, living under the same climatic environment, and practically homogeneous throughout in customs and speech. Consequently, they offer a problem which is not only sectional but general, and any light which may be thrown upon their development, particu larly the physical side, is of interest in connection with the general problem of the relation of man to his environment. Although the present investigation has been limited to local and racial com parisons, the peculiar situation of the Eskimo may make the results suggestive of the larger problem. In the following pages we have concerned ourselves chiefly with the description of skeletal material from a hitherto little-studied branch of this people, the Alaskan Eskimo. The collection includes twenty-eight crania, male, female, adolescent, and infantile, and three skeletons, brought down from Point Barrow, at the extreme northern point of Alaska, in 1898 by E. A. Mcllhenny. The Point Barrow Eskimo, as will be remembered from Murdoch's1 report, possess the simple Arctic culture characteristic of the more isolated tribes of the central and eastern Eskimo, and are as yet unin fluenced by an intermixture of Indian customs and mythology, as is the case with the more southerly Alaskan Eskimo tribes. Their isolation has also preserved the purity of their physical type. The only possibilities of intermixture are with the Athapascan tribes of the interior, who are very rarely met with on spring hunting trips into the interior, and from whom they are separated by inland Eskimo tribes, and with the white whalers, whose influence, as Stefansson has shown, has been of such short duration that it has not affected the native type. Furthermore, they are separated from the Mackenzie river Eskimo, the next division to the east, by some two hundred miles of uninhabited coast line, and only come in contact with them at infrequent intervals for trade at Barter island, or on whaling trips. 1 John Murdoch, "Ethnological Results of the Point Barrow Expedition" (Ninth Annual Report Bureau of Ethnology, pp. 1-441. Washington, 1892). HAWKES] SKELETAL MEASUREMENTS, POINT BARROW ESKIMO 2O5 Thus, the Point Barrow Eskimo have not been subject to Athapascan influence, like the interior Alaskan tribes, nor to the mixture of Northwest Coast and Russian customs present on the Yukon, nor directly to the strong Siberian influence in Bering strait. Consequently, they offer distinct advantages as a pure Alaskan group. For purposes of comparison the Southampton island Eskimo have been accepted as typical of the central group. Their situa tion precludes any possibility of Indian contact and they very rarely met even other Eskimo tribes. Furthermore, we have an excellent intensive physical study of these people by Dr. Hrdlicka,1 which is a great aid in comparison. In our comparative tables we have followed the accepted routes of Eskimo migration, which appear to reveal certain well-defined tendencies in physical type as well as culture. The Eskimo are particularly valuable as offering a fairly constant racial type for comparison with widely different Indian tribes throughout their extent. Their physical influence on two Indian stocks as different as the Athapascan and Algonkian is fully as significant as their cultural influences. Dr. Boas has suggested the strength of this influence in the east.2 On the other hand, it would appear from our investigation that the influence of the Indian on the Eskimo type in Alaska, at least in the northern section, has been overestimated. In the crania avail able we find that the majority of Alaskan Eskimo approximate the central type, and in individuals the racial characteristics, as the broad face, narrow nose, etc., are as strongly developed as in that area. Possibly the superior stature of the western group may be as much due to better food, clothing, and housing conditions as to an intermixture with Indian tribes, an assumption which has not yet been proven. Particular attention has been given in this investigation to sexual differences which were found to be considerable. We find 1 "Contribution to the Anthropology of the Central and Smith Sound Eskimo" (Anthropological Papers of the American Museum of Natural History, Vol. V., part i). 2 Franz Boas, "Physical Types of the Indians of Canada." (Annual Archaeolog ical Report, p. 88. Ontario, 1905.) 206 AMERICAN ANTHROPOLOGIST [N. s., 18, 1916 that the exaggerated features, such as breadth of face as compared with breadth of head, on which particular stress has been laid, are not expressed in the female, but are a characteristic of the male, not only in the Alaskan but in the other Eskimo groups. The general tendency is for the male to reproduce the racial type in an exaggerated form. Consequently, owing to the scarcity of female measurements, or the ignoring of sexual differences, as in Bessels' work,1 a set characteristic has been accepted as a racial trait. In dealing with the mandible we have followed the illuminating suggestions of Thompson and worked out the indices which indicate the leverage of the jaw. The theory of the comparative shallow- ness of the glenoid fossa in the Eskimo being the result of the rotary motion of the mandible and the food used by them, as embodied in the recent study by Knowles,2 has also been considered for this group. It was generally found to hold good and is being worked out in detail for later publicat on. The crania offered examples of infantile, adolescent, and adult forms of dentition, for which both dental and cusp 'formulae have been worked out. It was found that certain primitive character istics, such as the additional cusp of the third molar, and the meeting of the incisors edge to edge, were present in this group. The skeletal proportions are somewhat larger than those given by Hrdlicka for the Smith sound Eskimo, but the form is as typical. Certain very primitive characteristics, such as the perforation of the olecranon fossa and the extreme forward curve of the femur, were noted in the female skeleton. INCREASE IN STATURE AMONG THE WESTERN ESKIMO The Alaskan Eskimo are a taller and more symmetrical people than their brethren of the central and eastern districts. They lack that appearance of stoutness and squatness inherent in the eastern stock, and for proportion and development of the various parts of the body they do not compare unfavorably with Indians 1 Bessels, Emil. "Einige Worte iiber die Inuit (Eskimo) des Smith Sundes, nebst Bemerkungen iiber Inuit Schadel" (Archiv f. Anthropologie, VIII., 1875). 2 Knowles, F. H. S. " The Glenoid Fossa in the Skull of the Eskimo." (Canadian Geological Survey, Museum Bulletin, No. 9.) HAWKES] SKELETAL MEASUREMENTS, POINT BARROW ESKIMO 2O/ and whites. It is not unusual to find in an Alaskan Eskimo village several men who are six feet tall, with magnificent shoulders and arms and bodily strength in proportion. The usual height however is about 168 centimeters for men, which is some 10 cm. above the height of the eastern Eskimo. The Central Eskimo (Southampton islanders), according to Hrdlicka, average about 162 cm. in height. The average for women among the western Eskimo is 158 cm., which approximates the height of the men in the Hudson bay region (158 cm., Boas). The female type in Alaska is taller and slimmer than in the east, and the width of the face is considerably less. Eskimo women of large stature are often seen in the northern section of Alaska. The individual variation here is more conspicuous than in Labrador or Hudson bay. Whether these changes in physical type in the west are due to changed conditions or to intermixture with Indian or Asiatic tribes is an open question. The conditions of life of the Eskimo in the west are appreciably different. They occupy permanent villages of comfortable stone and wood iglus, as opposed to the shifting winter snowhouse and summer tent of the eastern group. For hunting game on the water, the Western Eskimo has for the most part abandoned the kayak for the larger and roomier umiak while most of the hunting on the sea ice and land is done on foot instead of with the dog sledge. Long distance foot races form one of their winter sports, and the boast of the old hunters is that they were able in their prime to run down a reindeer after an all day chase through deep snow. Consequently, we find the lower limbs much better developed here than we do further east. This may account in part for the increase in stature in the west. The rest of the body, as well as the long limbs, has developed into larger proportions in the west. Better food and clothing, as well as better housing, may have assisted here. To one who has seen both regions, as the author has been privileged to do, there can be no question as to the superior environment of the Western Eskimo. One coming from Alaska to Labrador and Hudson bay is struck with the poverty of life in the eastern district, the hazardous food supply, and the scantiness of the material culture. 14 208 AMERICAN ANTHROPOLOGIST [N. s., 18, 1916 The walrus, still abundant in Alaskan waters, have largely forsaken the eastern coast. Whales are more frequent in Arctic Alaska, although rapidly growing less, than in Hudson bay as the number of whaling ships might testify. There is no such tremendous competi tion by white sealers and fishers in the west as obtains on the Labrador coast. Although the eastern region has the advantage in wild reindeer, the Alaskan Eskimo has drawn on the tame herds of his cousin, the Chukchi, since early times, for warm clothing, and now, thanks to the American government, has herds of his own. The general outlook of the Eskimo ,in the west appears more favorable, and his condition an improvement over the old home region of Hudson bay. Consequently, we might expect increased stature without taking into account a possible intermixture with the Indians of the west, which is difficult of proof. The author does not see why the possibilities of intermixture with Indian tribes are any greater in the west than the east. So far as we know, the Eskimo have been in contact with the Indians in the east as long as in the west. In both regions there has been constant warfare and a deep-seated and ancient 'racial antipathy. No cases of intermixture have been recorded, although there is a bare possibility of an intermixture previous to historical times. It is true that the Alaskan Eskimo, from the Yukon south, have bor rowed much of Indian customs and mythology, but even here the racial type is well preserved and the boundary sharply marked. The northern Alaskan Eskimo have more intercourse with Siberia through the Diomede islands than with the interior Athapascan. A very ancient trade has been followed by a considerable inter mixture of blood in the Bering strait region. The inhabitants of the Diomedes take their descent in about equal proportions from the American and Asiatic sides of the strait. Those Eskimo who have penetrated to the Asiatic side (the Asiatic Eskimo) are now bi-lingual and have adopted the dress and habitations of the Chukchi. The amalgamation of these peoples is now nearly complete, the Eskimo only occupying a few remaining villages on the Siberian shore. Long before the advent of the white man in these parts, they made visits in company to the American side, first hostile, and HAWKES] SKELETAL MEASUREMENTS, POINT BARROW ESKIMO 2OQ later in the way of trade. Kotzebue sound was the ancient trading place, where the tribes gathered in summer in large numbers from both sides of the strait. It is in this section that we find the increase in stature most pronounced, rather than on the Yukon or in the extreme south. Consequently, we must take into account the possibility of intermixture from Siberia as well as from the interior of Alaska, in considering the changes in physical type of the Eskimo in the west. However, it must be remembered that these changes have not been sufficient as yet to overcome the main features of the original type. THE ACTION OF THE TEMPORAL MUSCLES ON THE SHAPE OF THE SKULL In the adult male crania of this series the temporal crest is well marked and very high (see pi. ix). It does not appear so prominently in. the female skulls and hardly at all in the infantile and adolescent series. The extensive plane covered by the temporal muscle on the adult skull would indicate a very strong development of the same. Arthur Thompson, in his paper on Man's Cranial Form, has worked out the possible effects of the lateral pressure exerted by the temporal muscles on the skull. This was done by exerting pressure by means of fibers of silk on the temporal plane of an artificial skull inflated with air, which resulted in a compensatory increase in the height and length of the skull. The experiment suggested that the action of the temporal muscles on the Eskimo skull was similar. Hrdlicka later showed that the effect of the temporal muscles on the infantile skull was slight, and, as the articulations became more firm, the increased resistance would offset the pressure of the muscles. He suggested that the temporal muscles act as confining pads, and that the growing skull, conforming to the line of least resistance, enlarges in the other two main directions, namely, height and length. The pressure of the temporal muscles is proportional to the amount of their use. Consequently, we should expect to find the female skull much more scaphoid than the male, as the Eskimo 2IO AMERICAN ANTHROPOLOGIST [N. s., 18, 1916 women are almost constantly engaged in chewing boot soles and skins outside of the regular exercise the muscles would get in eating. But the contrary is true. The female skull is broader and less scaphoid than the male, and the temporal surfaces less marked. The cephalic index of the female skulls is 76.06 in our series, as contrasted with the purely dolichocephalic skulls of the males, which average 72.65. The adolescent and infantile crania also tend toward mesocephaly, with average cephalic indices of 75.26 and 77.68 respectively. The term mesaticephalic, then, fits the appear ance of the female and young skulls more accurately. The doli chocephalic character of the head would appear to be attained in growth. In the more scaphoid type of the male skull perhaps we have another evidence of the adult male producing the racial char acteristics in an exaggerated form. SEX DIFFERENCES The importance of the sex variation in the Eskimo is considerable, and appears to have been overlooked by most investigators. Duck worth and Pain, in their valuable correlation of Eskimo head and skull measurements, were careful to make this distinction. The main variation in the Point Barrow skulls, outside of the more scaphoid appearance of the male skull already mentioned, is in the relation of the breadth of face to the width of the head. In nearly every case it is under 100 in the females and over 100 in the males, the breadth of face being excessive in the males but less than the width of head usually in the females. Both the facial and frontal width approximate the maximum breadth of the skull more closely in the female than in the male. The cephalic and altitudinal indices are higher in the female, although the capacity is consider ably less. The facial and nasal indices agree fairly well in both sexes. The palatal (external) index of the female is higher than that of the male, and the palate broader, due to the extensive use mentioned above. The alveolar prognathism of the two sexes is practically the same (97.53 being the alveolar index for males, and 97.198 for females). The adult condition does not seem to differ greatly from that of the adolescent (alveolar index 97.706). (See Table A.) HAWKES] SKELETAL MEASUREMENTS, POINT BARROW ESKIMO 211 The mandible of the male is heavier and larger absolutely, but not proportionally. The general development and lines in both sexes is similar. The coronoid index, which indicates the leverage of the jaw (as formulated by Thompson) , is remarkably uniform in TABLE A ESKIMO CRANIA FROM POINT BARROW, ALASKA Measurements as to Form; Prognalhism Cat.

The mandibular index is greater in the male (100.15 for males and 90.478 for females). This is due to the female mandible being rela- 212 AMERIC&N ANTHROPOLOGIST [N. s., 18, 1916 tively shorter and broader than the male, probably due to the more extensive rotary use of the same. The male mandible is approximately as long (condylosymphisial length) as it is wide (bi-condylar width.) The gripping and grinding powers of the jaws in both sexes is tremendous. The Eskimo workman uniformly uses his teeth to reinforce his hands in tightening lashings or undoing knots of frozen sealskin. The constant chewing by the women soon wears their teeth to a common level. The inclination of wear is slightly oblique, and pronouncedly so in the men, the outer edge of the teeth being worn on the lower jaw and conversely above (see pi. xiv). In both sexesS;here is a strengthening of the alveolar process at the molars to withstand the heavy strain put upon them. The molars themselves often show an extra cusp, and sometimes an accessory one, while the third molar in many cases has a foliated appearance, giving additional small cusps. The bones of the incomplete female skeleton were found to be much more primitive than those of the two male skeletons. The olecranon fossa were perforated, and there was an excessive forward curve of the femur which was absent in both male skeletons. The exostoses for the attachment of muscles were also more pronounced in .the, female skeleton. Generally speaking, the female skeleton strikes one as more primitive and less differentiated, and the male as more specialized toward a racial type. THE FORM OF THE PELVIS The female pelvis in the Eskimo is chiefly remarkable for its large dimensions. A specimen from Davis strait measured by Turner gave the following results: — Conjugate Transverse Oblique Brim 45/8 in. 6 in. 5 6/8 in. Cavity 55/8 " 52/8 " 54/8 " Outlet 52/8 " 51/8 " 54/8 " Circumference of Brim 16 1/2 in. Depth of Pelvis 4 Index of Brim 76 The female pelvis in the present series was incomplete, only one innominate bone remaining. The dimensions of the same were, — HAWKES] SKELETAL MEASUREMENTS, POINT BARROW ESKIMO 21$ height 205 mm., breadth 150 mm., index 73.13. The measurements of the male pelvis were as follows, — max. breadth (external) 299 mm., general pelvic index 78.92, ant. post, diameter 106 mm., lateral diameter (internal) 132 mm., pelvic index at superior strait 80.30. It will be seen from the above dimensions that in the Eskimo as in other races, the male pelvis is larger in the brim but smaller in the outlet than the female pelvis. The dimensions of the outlet appear to be unusually large in the female pelvis, which accounts for the swift and easy parturition of the Eskimo women reported. There is a general custom among the Alaskan Eskimo of expelling the infant by pressing on the abdomen. This operation is performed by certain old women, who act as midwives for the village. A stout sealskin thong is drawn tightly around the waist of the patient, the position of the child located, and pressure exerted downward by the operator, who stands behind the patient with hands locked over the abdomen. The patient kneels on the floor, in which position she is delivered in a short time. The operation is not usu ally commenced until labor is well under way. OCCURRENCE OF AN EXTRA VERTEBRA IN THE ESKIMO In the complete male skeleton (5864) thirteen dorsal vertebrae were found instead of the normal twelve. The eleventh, twelfth and thirteenth vertebrae closely approximated in form the normal tenth, eleventh, and twelfth. The thirteenth vertebra was of normal size and thickness, with well-developed lateral facets for the attach ment of ribs. The thirteenth rib was present on both sides, being rather smaller than the normal twelfth rib, but still well developed. The twelfth rib, on the other hand, was much longer than in normal individuals, and showed signs of cartilaginous attachment at the tips. The incomplete skeleton (5429) also gave evidence from the articulation of the presence of an additional vertebra between the twelfth dorsal and first lumbar vertebra. Turner in the Challenger Reports also mentions the occurrence of a supernumerary vertebra in this position in the case of two Australians and an Eskimo female skeleton examined by him. More recently Charles Dawson has 214 AMERICAN ANTHROPOLOGIST [N. s., 18, 1916 drawn attention to the frequency of extra vertebrae in the Eskimo. He treats it as a racial characteristic acquired through the continual balancing necessary in handling a kayak. The wonderfully light construction of this little craft, made of driftwood and skins, without keel or ballast, requires continual tension to keep it from capsizing. Under these circumstances, it is an advantage to have a flexible back and long waist, and the individual possessing these characteristics has a better chance of survival. When the kayak is overturned, he is able to right himself by a powerful twist of the body and stroke of the paddle. This trait, transmitted and become general through the survival of the fittest, would in time become a racial characteristic. Another factor making for a flexible waist is the backward bend of the hunter in poising the harpoon when in the kayak, and the continual twist of the body in using the double-bladed paddle on either side alternately.1 The additional vertebra is a simian characteristic and occurs in very primitive races. It is another evidence of the primitive structure of the Eskimo skeleton, in keeping with other anomalies discovered in this series as the perforation of the olecranon fossa, the extreme forward curve of the femur, etc. The lumbar curve in the Eskimo is, however, not in keeping with the primitive traits above mentioned, the index (after Cunningham) being intermediate between that of the European and those of the primitive peoples. The index for the Eskimo is 99.7, as opposed to 95.8 for the European and 107.8 for Australians, 106.6 for Bushmen, and 105.4 f°r negroes. The lumbovertebral index of 5864, in which the thirteenth dorsal vertebra was present, is 99.6, thus differing by only .1 from that given by Cunningham as the Eskimo normal. This apparently inconsistent characteristic of a supernumerary vertebra, in conjunction with a well-developed curve, may be ac counted for by the exercise of the waist mentioned above, which demands a high degree of suppleness and elasticity conducive to 1 The author does not wish to insist upon this possible explanation. In a large series of Eskimo skeletons from St. Lawrence island examined by a friend since this article was written, an extra vertebra was found in only two. So that it would appear to be a not uncommon anomaly among the Eskimo, rather than a racial trait. HAWKES] SKELETAL MEASUREMENTS, POINT BARROW ESKIMO 21$ the formation of 'compensatory vertebral curves. It is noteworthy that the Alaskan Eskimo, who do not use the kayak with the same expertness as the Greenlanders, from whom Dawson drew his material, nevertheless retain this racial characteristic of a well- marked clirve.1 OCCURRENCE OF OTHER ANOMALIES Although the Eskimo skull is scaphoid in shape, the sagittal suture remains open to an advanced age, in contradiction to the early closure of crania of this shape in other races, due.tQ lateral pressure. In only three of the twenty-eight Point Barrow skulls is there a complete fusion of the parietals. One of these is a male, and the other a female, both aged. The other case, curiously enough, is that of an adolescent skull. The sagittal suture is com pletely closed although the other sutures are well marked and den tition is incomplete. The shape of the adolescent skull is rounded rather than scaphoid. The female skulls are less scaphocephalic than the male. In several of the skulls of both sexes the metopic suture is not yet closed in the region of the glabella. The infra-orbital suture persists in a majority of cases. There are ten cases of the appear ance of Wormian bones in the occipital region, and one skull (5428) shows the rare Epiteric bone. A search for evidence of grooves formed by the supra-orbital nerves in the frontal region and blood vessels in the occipital,2 which are said to be rare in the Eskimo, failed to reveal anything in this series. The incisors, in the young as well as in the adults, meet edge to edge, instead of overlapping as in most races. The canines also meet instead of falling one behind the other and are worn down to a level with the incisors. They are much thickened and approach the pre-molar in shape. The position and wear of the front teeth sug- 1 Cunningham, Lumbar Curve in Man and the Apes.

Francis Dixon, Journal of Anatomy and Physiology, Vol. 38, 1904. 2l6 AMERICAN ANTHROPOLOGIST [N. s., 18, 1916 gests a side-to-side grinding movement of the jaw in the Eskimo as in Mousterian man, as opposed to the direct bite of civilized man. The extremely broad palate of the Eskimo is further evidence of this movement. Consequently, the teeth are worn off obliquely the inclination being inward on the upper jaw and outward on the lower. In one aged male skull (5403) the atlas is fused with the base of the skull, resulting in an obscuring of the outlines of the foramen magnum, which appears distorted. In another male skull (5404) the foramen magnum is decidedly asymmetrical. In 5408, owing to a diseased condition of the bone (plate xiv), the entire base of the skull is twisted out of shape. The pyriform shape of the foramen magnum was not noted in any of the crania. INFANTILE AND ADULT CHARACTERISTICS Duckworth and Pain, in "A Contribution to Eskimo Crani- ology, " have outlined those characteristics of Eskimo crania which they attribute to growth, and those which they believe are reten tions of infantile traits. The present series has been carefully gone over with this in mind. Of the infantile characteristics retained in the adult the following held good : the megasemic orbital aperture, the flattened nasal skeleton, the small mastoid processes, and the persistence of the infra-orbital suture. For the rest, the pyriform contour of the foramen magnum was not present in either the young or adults, the prominence of the chin was more apparent than real, and the most important infantile trait suggested, the dolichocephalic character of the skull, was not borne out by our re sults at all. Both the infantile skulls in our series are mesocephalic (indices 78.85 and 75.5), as are the three " young" skulls from Southampton island described by Hrdlicka, with cephalic indices of 78.1, 77, and 76.1 respectively. We would therefore be inclined to place the dolichocephalic character of the adult Eskimo head under those characteristics acquired by growth. To this we would add the other traits suggested by Duckworth and Pain tinder this head ; the low nasal index, depending on the extreme narrowness of the nasal aperture (which Hrdlicka suggests may be an adaption HAWKES] SKELETAL MEASUREMENTS, POINT BARROW ESKIMO 21? to extreme cold); the greater prominence of the malar bones, and the scaphocephalic cranium without sagittal synostosis. Of these the difference in nasal width is not great proportionally between young and adult skulls, and the scaphocephalic cranium is much more frequent in the males. INDIVIDUAL VARIATION The accompanying table of the variation of the indices of in dividuals within the three great Eskimo branches (see Table B) , eastern, central, and western, was suggested by a table of the individual variation in the indices of a set of Labrador and Green land skulls examined by Duckworth and Pain. It appeared feasible to extend this treatment to other Eskimo groups and denote the individual variation within each group and as compared with each other. The number of crania in the different groups is not exactly the same, but sufficiently close for general conclusions. For the central group the adult skulls of HrdliCka's Southampton islanders have been taken, and for the western, the adult crania in the present series. Hence, we have small but representative groups for comparison. In those indices which determine the racial affinity of Eskimo tribes, the cephalic . vertical , jnasal ,, and, orbital, the average indices of all three groups are very-close. Consequently, when we find the traits which the indices reveal, a dolichocephalic head, megasemic orbits, and leptorhinian nasal structure persisting throughout these groups, we may safely conclude that the racial relation is strong, and that the variations of tribe and tribe are less than the individual ones. We might further expect that the individual variation would be greatest in that branch which has been subjected to the addi tional stimulation afforded by an improved environment and con tact with races of a superior type and culture. Consequently, we find the individual variation more noticeable in the west, and the western type with lengthened face, shortened bi-zygomatic breadth, and increased stature somewhat different. But the change is a very gradual one from group to group, and the physical type, like the culture and language, dominated by the same essential traits throughout. 218 AMERICAN ANTHROPOLOGIST [N. s., 18, 1916 Judging from the indices, the relation of the Western Eskimo is closer to the Central than the Eastern Eskimo.

The increase from the adolescent breadth average of 132.1 is slight relative to the 220 AMERICAN ANTHROPOLOGIST [N. s., 18, 1916 increase from the adolescent length average of 175.6. It will be noted here, as elsewhere, that the female approximates the adolescent type. The well-known extreme length of head of the Eskimo is fully realized in this western group in the male series which attains an average of 189.1, which is as high as that of the purest central type (Southampton island, 189). There is considerable individual vari ation in the Point Barrow group, 182/196, which, however, is less than that of the central group, 179/204 for a smaller number. This phase has been dealt with by itself. It is not significant here, except to illustrate the fact, that with the supposedly purest groups of a racial type there is a large individual variation. The average length of the female skulls in our series is much less, 178.6, and the range of individual variation smaller, 173/182; which, taken in conjunction with the above-mentioned tendency to constancy of breadth of head, places them well within the limits of mesocephalic skulls. It should be borne in mind, however, that this is a result of the lessening of the extreme length of head in the female sex and not a consequent broadening. As will be shown in later tables, the females have not acquired in proportion to the breadth of head, the extreme breadth of face characteristic of the males, while they have preserved other prominent traits, as the narrow nasal aperture, the broad palate, and deep set orbits. The narrow-headedness of the Eskimo is well represented in the Point Barrow skulls. The average width, 137.3 f°r males and 136.8 for females, is less than that of the Southampton island Eskimo, 140 in males and 137 in females, but close to that of the Mackenzie Eskimo, 137 (Russell). There appears to be a tendency for the width of the head to decrease toward the west from the central region, which probably goes with a decrease of the width of face, until the broad-headed Aleutians are met with. Nevertheless, the racial tendency of the Eskimo toward a long, narrow head is as evident among the males in the west, as among the Eskimo gener ally in the east. As might be expected from the extreme length, the cephalic index of the males, (72.65) shows a well-marked tendency toward HAWKES] SKELETAL MEASUREMENTS, POINT BARROW ESKIMO 221 dojichocephaly . Only two skulls in the series give averages above 75 . The female skulls are more inclined to be mesocephalic, the average being 76.06. If we compare this figure with the adolescent average (75.26) we are again struck by the similarity of the female to the adolescent type. The infantile skulls give the high average of 77.68, owing to their lesser length. The breadth (126.5) remains remarkably close to the adult skulls. In Table 2 a comparison has been made of the cranial indices of the various branches of Eskimo. It will be seen that the cephalic TABLE 2.

That is, the head becomes less elongated and scaphoid, and more rounding in the west. Un fortunately, we do not possess figures for the indices of the sexes over this entire area, but in the central region the female cephalic and altitudinal index is slightly higher than that of the male and in the Point Barrow skulls notably so. Two female skulls in the Bering strait group have cephalic indices of 75.14 and 78.57 as compared to the indices of 72.68 and 78.87 in the two male skulls.

Within the western group itself, Table 3 shows the gradual rise of the mean of the cephalic index from the Mackenzie river to the Aleutian islands. The approach appears to be toward the broad- headed Aleutian type rather than the Athapascan of the interior. TABLE 3.

Stone, the interior Alaskan Eskimo radically differ from the Athapascans, with whom they come in contact, in the form of the head, the length and breadth of the face, and the shape of the nose. The superior height of the Eskimo skull gives it a larger capacity than would be judged from 1 Denotes mean measurements. Had it been possible to use the living measure ments of A. J. Stone on the Nunatagmuit, an interior Eskimo tribe situated between Point Barrow and Bering strait, with an average cephalic index of 81, and a mean measurement of 82, the step between the Bering strait Eskimo and the Aleut would be nicely bridged. The difference between the cephalic index of the head and the skull, according to Boas, is 2.2 for the Eastern Eskimo. \ I Z) < g AMERICAN ANTHROPOLOGIST N. S., VOL. 18, PL.

In fact, some heads are so scaphoid as to appear pathological. In spite of the extreme height of the Eskimo head, the altitudinal index is much diminished by the extreme length of the skull. Consequently, the Eskimo have a lower height indexsthan the Lapps, who have a notably low skull, and who attain a higher degree on account of their shortness of head. The height breadth index gives a truer picture of the proportionate shape of the head, outside of length. Topinard suggested a combination of the height and height-breadth indices, an averaging of the results obtained by each, which would accord more nearly with the appear ance of the crania. In ten cases out of fourteen in the male series of the Point Barrow skulls the height exceeds the width. Among the Eastern Eskimo the proportion is greater, the general type having a width of 144 mm. and a height of 150 mm. The average width of the Point Barrow male skulls is' 137.3 and the average height 138.7. The average height of the female crania shows a considerable decrease (133 mm.), whereas the width is nearly equal to that of the males (135.8). The difference of the sexes in relation to height and breadth of skull is well brought out in the height-breadth indices. In this series there is only one female skull which does not fall under 106 (the width exceeding the height), and only four male skulls which do not give an index above 100 (the height exceeding the width). The four male skulls in which the breadth exceeds the height possess certain peculiarities in common which leads to the suspicion that they may represent an intruding strain of blood from another Eskimo district. They all possess a very high and well-marked temporal ridge, a high keel, a narrow forehead but a wide and bulging backhead. All four show a height-breadth index of 97, and in three the measurement for height and breadth is identical, 137 mm. and 134 mm. Capacity. — In determining the capacity of the Point Barrow skulls an attempt was made to use the general formula of Dr. Lee1 but it was found that the results did not agree with the actual measurements. The scaphocephalic shape of the Eskimo head, 1 Phil. Trans., 196, A, 1901. 15 224 AMERICAN ANTHROPOLOGIST [N. s., 18, 1916 which increases the height out of all proportion, rendered the for mula useless.

In the infantile and adolescent series, owing to the lack of development of the orbital ridges, the Orphryanic measurement slightly exceeds that in the inter-orbital ne. The transverse arc is measured from the upper margin of the auditory meatus. HAWKES] SKELETAL MEASUREMENTS, POINT BARROW ESKIMO 22$ The size of the skull was also found to be no exact criterion of the capacity, due to the large variation in the thickness of the parietal bones. One skull that appeared to be above the average in size gave a capacity of only 1230 c.c., while another skull of slightly less exterior measurement gave a capacity of 1330 c.c. The variation appears greatest in male skulls. The capacity of the Point Barrow skulls as a whole is not as great as that of the Central and Eastern Eskimo. The average capacity of the male crania is 1426 c.c. as against 1563 c.c. for the Southampton island Eskimo (Hrdlicka). The largest Point Barrow skull has a capacity of 1610 c.c., so it will be seen that the capacity is still large in the west, and that the head still maintains this dis tinctly Eskimo character. The female average in this group is about 1300 c.c., the general average being brought down to 1287 c.c. by one very small skull. The adolescent average of 1301.1 c.c. is instructive in showing the close correlation between the female and adolescent types, which is confirmed in other measurements. The cause for the large capacity of the Eskimo skull still remains undiscovered. The superior inventiveness of this people is il lustrated in their ingenious culture. The brain is said to show good differentiation, but no signs of extraordinary mental powers (Hrdlicka). The diameter of the foramen magnum is large, in dicating a stout spinal cord, which may or may not have a direct influence on the size of the brain. The large capacity of the infan tile skulls, 1152.5 c.c., suggests that the large size of the brain is a racial trait, and not acquired through the educative process of their environment. Breadth of Face in Proportion to Breadth of Head. — The Eskimo of the central region and Greenland are characterized by a very broad face in proportion to the breadth of head. The general proportion is 1 02, ranging as high as 105 and 107 in individuals. Eighty- five skulls from Smith sound, measured by Bessels, gave an average head width of 133 and an average facial (bi-zygomatic) width of 136, a proportion of 102. Unfortunately, in his long list of crania, Bessels made no distinctions as to sex, and this is an important difference, as may be observed in the following comparative table. 226 AMERICAN ANTHROPOLOGIST [N. s., 18, 1916 TABLE 5 COMPARATIVE TABLE OF THE PROPORTION BETWEEN BREADTH OF HEAD AND BREADTH OF FACE OF ESKIMO GROUPS Locality No. Skulls Sex Collector Breadth Face Breadth Head Pro.

In series where no such differentiation has been made, as in Bessels' Smith sound Eskimo and Russell's Mackenzie Eskimo, the general average is slightly over 100 (102 and 101), which may be considered as the average between the two sexes. But these figures are mis leading, in that they fail to bring out the pronounced facial breadth in the male, and the lack of the same characteristic in the female. Consequently, owing to the small number of female skulls measured, and to their being lost sight of in the general average, the sex dif ferentiation has been lost, and the extreme breadth of face em phasized as a racial trait, when it holds good only for the males. It will be remembered that a similar error was made in the case of the Tasmanians.

Consequently, the total facial index is rather low (92.12 for males and 86.20 for females), although higher than in other Eskimo groups. In skull 5418 the symphisial height of the mandible is 42 mm., the upper face is also much elongated, so that the total facial length nearly equals the bi-zygomatic breadth. This head is a good example of the extreme individual variations we occasionally find in the Western Eskimo, although the majority keep reasonably close to the racial type. The adolescent total facial index (94.56) is higher than that of the adults. The upper facial index of the Point Barrow Eskimo does not differ much from that of the Southampton island Eskimo, as given by Hrdlicka. Taking the average of the adult crania of both sexes, twenty-one Point Barrow skulls give an average index of 53.09 and 13 Southampton island skulls give 52.65. These averages again are close to the figures given for eastern crania by Duckworth and Pain. For six Labrador and Greenland skulls the average facial index was 54.36. This leads us to conclude that the upper facial index is another constant factor in the various Eskimo branches. But in comparing the total facial (gonio-zygomatic) index we find an increase in the west, due to the increase in total facial height in that quarter. Six male Point Barrow skulls have an average height from chin to nasion of 131.5 mm. as contrasted with six male Southampton island crania, which give a total facial length of 126 mm. (The number of male crania with mandibles happens in both groups to be the same.) Since the approximation between the head and skull measurements for facial indices has been found to be close, we may compare these measurements with those of Stone on living Alaskan natives, making allowance for a small variation (2.2, Boas, for Eastern Eskimo).

The Eskimo are the most leptorrhine of known races, with a nasal index of 42.33 (Broca). The Point Barrow tribe have not lost this distinctly Eskimo trait. In fact, their nasal index is slightly lower than that of the Southampton island Eskimo. The Point Barrow male crania in our series have a nasal index of 40.69 and the female of 41.62 (see Table 7); the Southampton island skulls have a nasal index of 42.3 for males and 45.8 for females. The Labrador and Greenland skulls measured by Duckworth and Pain gave an average nasal index of 45.55. There is a larger individual variation in the western group than in the others (see Table of Variations1). One Point Barrow skull gives an index as low as 33.93. This does not mean necessarily that the Western Eskimo is a less pure type. The same causes which led to an increase of stature, a more certain and abundant food supply during the period of growth and improved conditions, may have also increased the variation in other character istic racial traits. It will be noted that in the nasal index the females again are nearer the adolescent type. (Males 40.69; females 41.62; adolescents 42.54.) Orbital Index. — The high value of the orbital index is another racial characteristic of the Eskimo, which it shares with the Indians of North America and the yellow race of Asia, in contradistinction to the low nasal index, which differentiates them from both. At the same time the Eskimo eye differs in appearance from the Mon golian. The megasemic character of the Eskimo orbits in the adult is regarded by Duckworth and Pain as the retention of an infantile trait. This conclusion appears to be well borne out in the male skulls in the present series and in Hrdlicka's measurements of the Southampton islanders. The index of the female skulls in the Point Barrow group falls slightly under megaseme (88.938) for the right and 88.156 for the left orbital index (see Table 8). The sexual variation of the orbital index is considerable, due largely to the greater development of the supra-orbital ridges in the male, 1 Duckworth and Pain.

The orbits in the female skulls are rounder and less irregular than those in the male skulls. The proportion of height and breadth of the orbits is nearly equal in the adolescent crania, and the height exceeds the width in the infantile skulls. The depth of the orbits is remarkable in all the crania. The variation of the right and left orbits in individual skulls is noticeable, the difference being mainly in width. 232 AMERICAN ANTHROPOLOGIST [N. s., 18, 1916 Palatal Index. — The palate of the Point Barrow Eskimo is characterized by extreme breadth. In this racial feature they slightly exceed the Central Eskimo. The present series gives a palatal (external) index of 118.31 for males and 122.7 f°r females, and the Southampton island Eskimo 118.8 for males and 120 for females (Hrdlicka). Within the Point Barrow series there is an occasional skull in which the palate is longer and narrower than the average. (Two male skulls give a palatal index of 106.78 and 109.80.) But the general tendency is to a very broad palate. The palate of the adolescent and infantile crania is relatively shorter than that of the adults, but partakes of the characteristic horseshoe shape.

The ascending rami are broad and heavy and the coronoid processes low and stout. The extent of the condylo-coronoid width gives additional leverage to the temporal muscle. The surface roughenings for muscular attachment are very prominent (pi. xv), the area for the insertion of the masseter and pterygoid muscles being very extensive. The extraordinary pressure to which the jaw is subjected has led to an accessory thickening in the alveolar process at the second molar. This occurs in the adolescent and infantile jaws as well as the adult, so it probably is an inherited trait. One of the male mandibles (fig. 26) exhibits a diseased condition, which has resulted in atrophy of the alveolar and coronoid processes and a shriveling of one side of the jaw. The skull is similarly affected at the base and 234 AMERICAN ANTHROPOLOGIST [N. s., 18, 1916 rendered asymmetrical by adjustment to the disproportionate posi tion of the mandible.

The direction of the wear is oblique, being inward on the upper jaw, and outward on the lower. The inclination is due to the outer margins of the central lateral teeth of the lower jaw being brought into contact with the inner sides of the opposing teeth in the upper jaw during the grinding sideways movements of the mandible (Knowles). The extremely tough nature of the Eskimo food, much of which is eaten raw or dried, renders the rotary chewing process much more necessary than in other savage races that live almost entirely on fresh meat. The fondness of the Eskimo for chewing tough skin of the whale or mukluk (big seal), and the regular work of the women in chewing boot soles and skins, increases this tendency. The crowns of all the teeth are heavy, even the canine approach ing the premolar in shape. In the molars an additional tubercle is often present, and occasionally an accessory one. The third molar frequently takes on a foliated appearance, with additional small tubercles (see cuspid formulae).

MEASUREMENTS OF OTHER SKELETAL PARTS THAN THE CRANIA IN THREE ESKIMO SKELETONS FROM POINT BARROW. (RALPH LINTON) Sternum and Ribs. — The sterna in both skeletons examined are asymmetrical, the supersternal notch being to the left of the median line. The pre-mesosternal suture slopes downward from left to right, whereas the supersternal notch slopes from right to left. HAWKES] SKELETAL MEASUREMENTS, POINT BARROW ESKIMO 237 The asymmetry of the manubrium is indicated in the following measurements.

The depression of the right side, however, appears to be confined to it. The levels of articulation with the ribs, the costal facets, are noticeably higher on the right side than on the left, not only as regards the upper facets, as is more usual (Thompson), but in the case of the lower as well. The same causes which led to asymmetry of the manubrium have also led to a corresponding lengthening of the right first rib and clavicle. In both skeletons the right clavicle is four mm. longer than the left, and the first rib from one to five mm. longer on the right than the left. The contraction of the left side has resulted in a thickening of the bones and an increase of their curve with a corresponding diminution of the curve in those on the right side.1 1 The depression of the right shoulder, and resultant changes already noted are not confined to any one race. It has been noted in the white race and is said to be caused by carrying heavy objects on the right shoulder, or more particularly in the right hand. The heavy harpoon and dog whip which the Eskimo are accustomed to carry in the right hand, as well as the more extended use of the same, may have caused an exaggeration of this tendency. A curious anomaly is the existence of a thirteenth rib in connection with an additional thoracic vertebra in 5864. It may have been present in 5429 also, as this skeleton had the additional vertebra, but is now incomplete. The thirteenth rib occurs on both sides, the length being 89 mm. for the right and 87.5 for the left. They are roughened for muscular attachment and the articular facets are large and well developed. In shape, and the arrangement of bony protuberances, they agree with the twelfth rib of normal individuals. In both 5864 and 5429 the twelfth rib is abnormally long (in 5864 156 mm. for the right and 152 mm. for the left) and its tip deeply pitted for the attachment of cartilage. 238 AMERICAN ANTHROPOLOGIST [N. s., 18, 1916 In 5864 ossification has not yet taken place between the first and second parts of the mesosternum, nor between it and the manu- brium, but is complete between the second and third part of the mesosternum, indicating that the skeleton is that of a young adult. In 5429 ossification is complete in the mesosternum and partial between the mesosternum and manubrium, indicating an advanced age. In 5864 the xiphisternum is ossified, but is not yet attached to the body of the sternum. 5429 is much broader, heavier, and thicker than 5864, as the following measurements show.

The vertebrae of both are well developed as to strength. In 5429 there are marginal exostoses, and the laminae and spinous process of the fifth lumbar vertebra are separate, ar ticulating with the proximal part of the arch. The same anomaly has been noted in the fourth and fifth lumbar vertebrae of a specimen from Smith sound described by Dr. Hrdlicka. In addition the lateral spine on the right side of the second lumbar vertebra is separate, and there is a facet present for its articulation. The thirteenth thoracic vertebra is present in both specimens; and has been described at length elsewhere (see Occurrence of an Extra Vertebra in the Eskimo) . Except for this peculiarity 5864 is normal in every way. The indices of the five lumbar vertebrae (taken according to Cunningham) are as follows: — HAWKES] SKELETAL MEASUREMENTS, POINT BARROW ESKIMO 239 Cat.

In respect to the lumbar curve, the Eskimo occupies a position about midway between the European and the primitive peoples, such as the Australians, Bushmen, etc. The environmental factors which might lead to this have already been dealt with (see Occurrence of an Extra Verte bra in the Eskimo). Innominate Bone. — The innominate bones are strong and well developed, but in no way depart from normal. The measurements are as follows :— 0 Cat.

The wall of the spinal canal is deficient from the beginning of the fourth segment. The normal five segments are present, and there is no indication that the first sacral vertebra has become detached to form a sixth lumbar at the same time that the first coccygeal has become ossified to the sacrum, as was the case in the two spines containing an additional vertebra described by Lane.1 Cat.

Breadth (max ) Index 5864 male 124 120 96.77 Scapula. — The scapulae are remarkable for their length and nar rowness, corresponding closely to those from Smith sound described by Hrdlicka. 1 W. Arbuthnot Lane, "Some Variations in the Human Skeleton," Journal of Anatomy and Physiology, Vol. 20, Third Part, April, 1886. 16 24O AMERICAN ANTHROPOLOGIST [N. s., 18, 1916 The scapular and infrascapular indices corresponded fairly well with those given by Flower.1 These indices form a marked ex ception to the primitive traits usually found in Eskimo skeletons, for they are at the other extreme from those of the anthropoids, while the indices of Europeans occupy a position about midway between. The right glenoid fossa of 5864 is larger than the left, the di mensions being 42x28.2 and 42x27.1, respectively. In all the scapulae examined, the superior border forms a deep, almost U-shaped notch, the characteristic being most exaggerated in 5864 and least so in 5429, in which the suprascapular notch is well marked. This concavity of the superior border of the scapula appears to be a racial characteristic, being more .or less common throughout all the Eskimo groups. It rarely occurs in whites or Indians. The scapulae of a gorilla in the Wistar Institute collection shows this same concavity, the resemblance being striking. On the other hand, it did not occur in any of eight orang utan skeletons examined. The cause of this anomaly is not evident in the culture of the Eskimo, and it may well be an inherited evolutionary trait. Clavicle. — Special mention has been made elsewhere of the lengthening and strengthening of the clavicle on the right side in connection with asymmetry of the first rib. The bones are other wise normal, being fairly strong, with roughenings for muscular attachment well, but not excessively developed. Cat. No. 5864 (Male) 5429 (Fern.?) Right Left Right Left Length 168 164 144 140 Humerus. — The humeri of 5863 were both perforated in the olecranon fossa, the openings being of fair size, and the left larger than the right. This seems to be a primitive, although scarcely simian characteristic, being of more frequent occurrence in the anthropoids than in man, and in the ancient than the modern races. Even in the anthropoids it is an individual variation. Its most frequent occurrence among human beings is in prehistoric 1 W. H. Flower and Dr. J. G.

Indian skeletons from Arizona, in one collection of which no less than 54 per cent, had one or both humeri perforated.1 It is not common in any living race, but occurs oftener among primitive peoples than it does among Europeans.

Max. length 270 271 233 Femur. — In 5864 the femora are powerfully built, and exceed in length the average for both whites and Indians. The longest femur among the specimens from Smith sound described by Hrdlicka was 467, while the average for males was 380.9, as opposed to 489 in this specimen. 5863 also exceeds either of the adult females described by him, being 403, as opposed to 386 for the larger of his specimens, which he expressly states was fairly tall for an individual from the eastern group. This length is the more remarkable in that the femora in question (5863) have an excessive forward curve, and very heavy shaft. The entire surface of the bone is slightly roughened, and the gluteal ridge and linea aspera are excessively developed, giving the specimens a disproportionate anterior posterior diameter at the middle. The whole appearance of the bone is very primitive. 1 Dr. D. S. Lamb, "The Olecranon Perforation," American Anthropologist, Vol. III.. 1890. 242 AMERICAN ANTHROPOLOGIST [N. s., 18, 1916 Cat.

The length of the tibiae of 5864 is somewhat above the average for white males, although that of 5863 is slightly below the figures given for white females. In the former the right tibia is 8 mm. longer than the left. The tibio-femoral index was above 84, thus showing a greater proportional length of tibia than in the Smith sound group, or even whites. The anterior posterior diameters were also found to be somewhat greater than for whites of corresponding sexes. This shows a considerable variation from the Smith sound group, in which they were less. On the whole, it seems that the Alaskan Eskimo have much longer and stronger legs than their eastern relatives, a difference which can be easily accounted for by their habit of taking long hunting expeditions on foot, and by their use of the roomy umiak instead of the kayak, which cramps the legs. A more certain and plentiful supply of food during the period of growth may also be an important factor in insuring a good develop ment of the long bones. TIBIA (MEASUREMENTS) Cat.
