Let us take up the Year Books, which, even in their present state, afford such an inestimable source of information for the history of legal conceptions in the fourteenth and fifteenth centuries[44]. An examination of the reports in the age of the Edwards will show at once that the terms _regardant_ and _in gross_ are used, or rather come into use, in the fourteenth century as definitions of the mode of pleading in particular cases. They are suggested by difference in title, but they do not coincide with it, and any attempt to make them coincide must certainly lead to misapprehension. I mean this--the term 'villain regardant' applied to a man does not imply that the person in question has any status superior to that of the 'villain in gross,' and it does not imply that the lord has acquired a title to him by some particular mode of acquisition, e.g. by prescription as contrasted with grant or confession; it simply implies that for the purpose of the matter then in hand, for the purpose of the case that is then being argued, the lord is asserting and hoping to prove a title to the villain by relying on a title to a manor with which the villain is or has been connected--title it must be remembered is one thing, proof of title is another. As the contrast is based on pleading and not on title, one and the same person may be taken and described in one case as a villain regardant to a manor, and in another as a villain in gross. And now for the proof. The expression 'regardant' never occurs in the pleadings at all, but 'regardant to a manor' is used often. From Edward III's time it is used quite as a matter of course in the formula of the 'exceptio' or special plea of villainage[45]. That is, if the defendant pleaded in bar of an action that the plaintiff was his bondman he generally said, I am not bound to answer A, because he is my villain and I am seised of him as of my villain as regardant to my manor of C. Of course there are other cases when the term is employed, but the plea in bar is by far the most common one and may stand for a test. This manner of pleading is only coming gradually into use in the fourteenth century, and we actually see how it is taking shape and spreading. As a rule the Year Books of Edward I's time have not got it. The defendant puts in his plea unqualified. 'He ought not to be answered because he is our villain' (Y.B. 21/22 Edward I, p. 166, ed. Horwood). There is a case in 1313 when a preliminary skirmish between the counsel on either side took place as to the sufficiency of the defendant's plea in bar, the plaintiff contending that it was not precise enough. Here, if any where, we should expect the term '_regardant_,' but it is not forthcoming[46]. What is more, and what ought to have prevented any mistake, the official records of trials on the Plea Rolls up to Edward II always use the plain assertion, 'villanus ... et tenet in villenagio[47].' The practice of naming the
