When two or three legal conceptions are spoken of as anciently blended in one, it is not intended to imply that some one o the included notions may not be older than the others, or, when those other have been formed, may not greatly predominate over and take precedence over them. The reason why one legal conception continues so long to cover several conceptions, and one technical phrase to do instead of several, is doubtless that practical changes are accomplished in the law of primitive societies long before men see occasion to notice or name them. Though I have said that Patriarchal Power was not at first distinguished according to the objects over which it was exercised, I feel sure that Power over Children was the root of the old conception of Power; and I cannot doubt that the earliest use of the Nexum, and the one primarily regarded by those who resorted to it, was to give proper solemnity to the alienation of property. It is likely that a very slight perversion of the Nexum from its original functions first gave rise to its employment in Contracts, and that the very slightness of the change long prevented its being appreciated or noticed. The old name remained because men had not become conscious that they wanted a new one; the old notion clung to the mind because nobody had seen reason to be at the pains of examining it. We have had the process clearly exemplified in the history of Testaments. A Will was at first a simple conveyance of property. It was only the enormous practical difference that gradually showed itself between this particular conveyance and all others which caused it to be regarded separately, and even as it was, centuries elapsed before the ameliorators of law cleared away the useless encumbrance of the nominal mancipation, and consented to care for nothing in the Will but the expressed intentions of the Testator. It is unfortunate that we cannot track the early history of Contracts with the same absolute confidence as the early history of Wills, but we are not quite without hints that contracts first showed themselves through the nexum being put to a new use and afterwards obtained recognition as distinct transactions through the important practical consequences of the experiment. There is some, but not very violent, conjecture in the following delineation of the process. Let us conceive a sale for ready money as the normal type of the Nexum. The seller brought the property of which he intended to dispose -- a slave, for example -- the purchaser attended with the rough ingots of copper which served for money and an indispensable assistant, the libripens, presented himself with a pair of scales. The slave with certain fixed formalities was handed over to the vendee -- the copper was weighed by the libripens and passed to the vendor. So long as the business lasted it was a nexum, and the parties were nexi; but the moment it was completed, the nexum ended, and the vendor and purchaser ceased to bear the name derived from their momentary relation. But now, let us move a step onward in commercial history. Suppose the slave transferred, but the money not paid. In that case, the nexum is finished, so far as the seller is concerned, and when he has once handed over his property, he is no longer nexus; but, in regard to the purchaser, the nexum continues. The transaction, as to his part of it, is incomplete, and he is still considered to be nexus. It follows, therefore, that the same term described the Conveyance by which the right of property was transmitted, and the personal obligation of the debtor for the unpaid purchase-money. We may still go forward, and picture to ourselves a proceeding wholly formal, in which nothing is handed over and nothing paid; we are brought at once to a transaction indicative of much higher commercial activity, an executory Contract of Sale.
