At the same time, we have indicated that on occasions of ceremony, whether religious or otherwise, the dress adopted is, as a rule, more primitive or older in style than that which is customarily worn. This is what might be expected, as, on the one hand, innate conservatism and objection to change come into play, and, on the other, ordinary everyday practical matters being for the time put on one side, it is possible to wear clothes which otherwise would be inconvenient and liable to get damaged. When we ourselves dress for dinner we go back nearly a century, but nothing could be more primitive than the Court etiquette of certain tribes,[16] where the subjects of the king may only approach him when entirely unclothed. Livingstone was received by the Queen of the Balonde Negroes in South Africa when she was in a state of complete nudity. The women of neighbouring tribes and members of other races, for instance those in Australia, entirely remove their clothing on festive occasions. Among some black races, also, the girls who are sent as official messengers to important persons are not clothed. There are still certain tribes of "leaf wearers" in India, while at a yearly festival in Madras the whole low-caste population throw off their ordinary clothing and put on aprons of leafy twigs. Another case in point is that of the priests who conducted the sacrifices in ancient Italy and Greece, for they are often represented on monuments as being naked, while the rest of those present at the ceremony are fully clothed. In taking up the question of ceremonial dress among civilized peoples, we find that we have a very wide field in which to wander. We have the Court, which might alone occupy our whole attention; we have naval, military, ecclesiastical, and legal dress, the garb of the universities, the costume of pantomime characters, of the acrobat, of the athlete, and the liveries of servants, besides the costumes adopted for special ceremonies and in connection with particular institutions. In treating of survivals in the case of the army, where the variety in uniform--if we may use this paradoxical expression--is so great, we may content ourselves with discussing matters in a way similar to that which we have adopted before. On the other hand, we may also describe and illustrate particular costumes, as a whole, while showing how far their history may carry us back. In addition to the clothes actually worn by persons, there are those which are found on dolls. These may be on the representations of personages such as St. Nicholas, on the Continent and elsewhere, and they are interesting because in many cases they may show a national costume which is no longer worn. In the same way, puppets such as are used in the play which we know as Punch and Judy, and their dresses, like others which we have studied, may bring to our notice chapters of history in a way that is exceedingly attractive.
