The mammoth drawing from La Madelaine Cave; the bison, imperfect, showing only the hind-quarters; and the ibex, on reindeer-antler, from Laugerie Basse; the group of reindeers from the Dordogne, two walking and one lying on its back; the cave-bear of the Pyrenees, from the cave of Massat, in the department of Ariége; and another sketch representing a hunter stalking the Urus: may all be regarded as right-hand drawings. But the horses from La Madelaine, engraved on reindeer-antler, specially noticeable for their large heads; the horse, from Creswell Crags; and, above all, the remarkably spirited drawing of the reindeer grazing, from Thayngen in the Kesserloch--a sketch, marked by incident, both in the action of the animal and its surroundings, suggestive of an actual study from nature,--all appear to be left-hand drawings. The number of examples thus far adduced is obviously too small to admit of any general conclusions as to the relative use of the right or left hand being based on their evidence; but so far as it goes, while it presents one striking example of a left-handed drawing, it confirms the idea of the predominance of right-handedness at that remote stage in the history of European man. It confirms, moreover, the correctness of the distinction already made between the preferential use of either hand by the cultured and skilled workman, or the artist, and its employment among rude, unskilled labourers engaged in such toil as may be readily accomplished by either hand. That the use of the left hand is transmitted from parent to child, and so, like other peculiarities, is to some extent hereditary, is undoubted. This has, therefore, to be kept in view in drawing any comprehensive deductions from a few examples confined to two or three localities. It may be that the skilled draftsman of the Vézère, or the gifted artist to whom we owe the Kesserloch drawing, belonged to a family, or possibly a tribe, among whom left-handedness prevailed to an unusual extent; and so might be developed not only hereditarily but by imitation. But on the other hand, even among those palæolithic draftsmen, there is a distinct preference for the right hand in the majority of cases; and this is just what was to be expected. The more the subject is studied it becomes manifest that education, with the stimulus furnished by the necessities arising from all combined action, has much to do with a full development of right-handedness. The bias is unquestionably in that direction; but with many it is not so active as to be beyond the reach of education, such as the habit and usage of companions would supply, to overcome it. But with a considerable number the preferential use of the right hand is prompted by a strong, if not unconquerable instinctive impulse. A smaller number are no less strongly impelled to the use of the left hand. In the ruder conditions of society each man is free to follow the natural bias; and in the absence or rare
