Rh 50 A B I A B L hand, while interpreting the results of past observation and experiment in their own favour, are yet less disposed to rest on these, rather preferring to argue from those wide analogies of evolution and correlation which seem to support their doctrine. Thus Haeckel expressly embraces Abiogenesis as a necessary and integral part of the theory of universal evolution ; and Huxley, in the same spirit, though from the opposite camp, confesses that if it were given him to look beyond the abyss of geologically recorded time to the still more remote period when the earth was passing through physical and chemical con ditions, he should expect to be a witness of the evolution of living protoplasm from not-living matter. (Critiques and Addresses, p. 239.) From this point of view, of course, any microscopic observations that have been made seem very limited and comparatively unimportant. The Abiogenists, indeed, are not without arguments to oppose the results of past observation that seem unfavourable to their views ; they argue that, as yet, all the forms observed and shown to be produced by Biogenesis are forms possessing a certain degree of organisation, which in their case makes Abiogenesis unlikely, from the first ; whereas it has not been shown that the simplest struc tures the Monera do not arise by Abiogenesis. But it is not so much on grounds of fact and experiment the defenders of the Abiogenesis theory are convinced of its truth, as because it seems to gain confirmation from reasonings of much wider scope; because Abiogenesis aids the theory of evolution by tracing the organic into the inorganic ; because it fosters the increasing unpopularity of the hypothesis of a special &quot;vital force;&quot; and because, if this theory of the &quot; perpetual origination of low forms of life, now, as in all past epochs,&quot; were established, it would agree well with the principle of uniformity, and by disclosing the existence of unknown worlds of material for development, would relieve natural selection with its assist ing causes from what many consider the too Herculean labour of evolving all species from one or a very few primary forms. The fullest discussion of the subject of Abiogenesis, from the Abiogenist s point of view, is to be found in Dr Bastian s Beginnings of Life. Professor Huxley s address, already referred to, contains an interest ing historical survey, as well as a masterly summary of facts and arguments in favour of Biogenesis. For many interesting experiments, see Nature, 1870-73. ABIPONES, a tribe of South American Indians, inhabit ing the territory lying between Santa Fe and Sfc lago. They originally occupied the Chaco district of Paraguay, but were driven thence by the hostility of the Spaniards. According to M. Dobrizhoffer, who, towards the end of last century, lived among them for a period of seven years, they have many singular customs and characteristics. They seldom marry before the age of thirty, are chaste and otherwise virtuous in their lives, though they practise infanticide, and are without the idea of God. &quot; With the Abipones,&quot; says Darwin, &quot; when a man chooses a wife, he bargains with the parents about the price. But it fre quently happens that the girl rescinds what has been agreed upon between the parents and bridegroom, obsti nately rejecting the very mention of marriage. She often runs away and hides herself, and thus eludes the bride groom.&quot; The Abiponian women suckle those infants that are spared for the space of two years, an onerous habit, which is believed to have led to infanticide as a means of escape. The men are brave in war, and pre-eminently expert in swimming and horsemanship. Numerically the tribe is insignificant. M. Dobrizhoffer s account of the Abiponians was translated into English by Sara Coleridge, at the suggestion of Mr Southey, in 1822. ABJURATION. See ALLEGIANCE, OATH OP. ABKHASIA, or ABASIA, a tract of Asiatic Russia, on the border of the Black Sea, comprehending between lat. 42 30 and 44 45 N. and between long. 37 3 and 40 36 E. The high mountains of the Caucasus on the N. and N.E. divide it from Circassia; on the S.E. it is bounded by Mingrelia; and on the S.W. by the Black Sea. Though the country is generally mountainous, there are some deep well-watered valleys, and the climate is mild. The soil is fertile, producing grain, grapes, and other fruits. Some of the inhabitants devote themselves to agriculture, some to the rearing of cattle and horses, and not a few support themselves by piracy and robbery. Honey is largely produced, and is exported to Turkey; and excellent arms are made. Both in ancient and in modern times there has been considerable traffic in slaves. This country was early known to the ancients, and was subdued by the Emperor Justinian, who introduced civilisation and Chris tianity. Afterwards the Persians, then the Georgians, and more recently the Turks, ruled over the land. Under the Turks Christianity gradually disappeared, and Moham medanism was introduced in its stead. By the treaties of Akerman and Adrianople, Russia obtained possession of the fortresses of this territory; but till the insurrection of 1866, the chiefs had almost unlimited power. The prin cipal town is Sukumkaleh. The population of Abkhasia is variously stated at from 50,000 to 250,000. See Pal- grave s Essays on Eastern Questions, 1872. ABLUTION, a ceremonial purification, practised in nearly every age and nation. It consisted in washing the body in whole or part, so as to cleanse it symbolically from defilement, and to prepare it for religious observances. Among the Jews we find no trace of the ceremony in patri archal times, but it was repeatedly enjoined and strictly enforced under the Mosaic economy. It denoted either (1.) Cleansing from the taint of an inferior and less pure condition, and initiation into a higher and purer state, as in the case of Aaron and his sons on their being set apart to the priesthood; or (2.) Cleansing from the soil of common life, in preparation for special acts of worship, as in the case of the priests who were commanded, upon pain of death, to wash their hands and feet before approaching the altar; or (3.) Cleansing from the pollution occasioned by particular acts and circumstances, as in the case of the eleven species of unclcanness mentioned in the Mosaic law; or (4.) The absolving or purifying one s self from the guilt of some particular criminal act, as in the case of Pilate at the trial of the Saviour. The sanitary reasons which, in a warm climate and with a dry sandy soil, ren dered frequent ablution an imperative necessity, must not be allowed to empty the act of its symbolic meaning. In the Hebrew different words are used for the washing of the hands before meals, which was done for the sake of cleanliness and comfort, and for the washing or plunging enjoined by the ceremonial law. At the same time it is impossible to doubt that the considerations which made the law so suitable in a physical point of view were present to the mind of the Lawgiver when the rite was enjoined. Traces of the practice are to be found in the history of nearly every nation. The customs of the Mohammedans, in this as in other matters, are closely analogous to those of the Jews. With them ablution must in every case pre cede the exercise of prayer, and their law provides that in the desert, where water is not to be found, the Arabs may perform the rite with sand. Various forms of ablution practised by different nations are mentioned in the sixth book of the ,/Encid, and we are told that ^Eneas washed his ensanguined hands after the battle before touching his Penates. Symbolic ablution finds a place under the New Testament dispensation in the rite of baptism, which is observed, though with some variety of form and circum-
