Scotland and realty in England, over the personalty to which they were opposed. The lawyers of all systems have spared no pains in striving to refer these classifications to some intelligible principle; but the reasons of the severance must ever be vainly sought for in the philosophy of law: they belong not to its philosophy, but to its history. The explanation which appears to cover the greatest number of instances is, that the objects of enjoyment honoured above the rest were the forms of property known first and earliest to each particular community, and dignified therefore emphatically with the designation of _Property_. On the other hand, the articles not enumerated among the favoured objects seem to have been placed on a lower standing, because the knowledge of their value was posterior to the epoch at which the catalogue of superior property was settled. They were at first unknown, rare, limited in their uses, or else regarded as mere appendages to the privileged objects. Thus, though the Roman Res Mancipi included a number of moveable articles of great value, still the most costly jewels were never allowed to take rank as Res Mancipi, because they were unknown to the early Romans. In the same way chattels real in England are said to have been degraded to the footing of personalty, from the infrequency and valuelessness of such estates under the feudal land-law. But the grand point of interest is, the continued degradation of these commodities when their importance had increased and their number had multiplied. Why were they not successively included among the favoured objects of enjoyment? One reason is found in the stubbornness with which Ancient Law adheres to its classifications. It is a characteristic both of uneducated minds and of early societies, that they are little able to conceive a general rule apart from the particular applications of it with which they are practically familiar. They cannot dissociate a general term or maxim from the special examples which meet them in daily experience; and in this way the designation covering the best-known forms of property is denied to articles which exactly resemble them in being objects of enjoyment and subjects of right. But to these influences, which exert peculiar force in a subject-matter so stable as that of law, are afterwards added others more consistent with progress in enlightenment and in the conceptions of general expediency. Courts and lawyers become at last alive to the inconvenience of the embarrassing formalities required for the transfer, recovery, or devolution of the favoured commodities, and grow unwilling to fetter the newer descriptions of property with the technical trammels which characterised the infancy of law. Hence arises a disposition to keep these last on a lower grade in the arrangements of Jurisprudence, and to permit their transfer by simpler processes than those which, in archaic conveyances, serve as
