HE should consider his course as a general map of the law, marking out the shape of the country, it's connexions and boundaries, it's greater divisions and principal cities: it is not his business to describe minutely the subordinate limits, or to fix the longitude and latitude of every inconsiderable hamlet. His attention should be engaged, like that of the readers in Fortescue's inns of chancery, "in tracing out the originals and as it were the elements of the law." For if, as Justinian[r] has observed, the tender understanding of the student be loaded at the first with a multitude and variety of matter, it will either occasion him to desert his studies, or will carry him heavily through them, with much labour, delay, and despondence. These originals should be traced to their fountains, as well as our distance will permit; to the customs of the Britons and Germans, as recorded by Caesar and Tacitus; to the codes of the northern nations on the continent, and more especially to those of our own Saxon princes; to the rules of the Roman law, either left here in the days of Papinian, or imported by Vacarius and his followers; but, above all, to that inexhaustible reservoir of legal antiquities and learning, the feodal law, or, as Spelman[s] has entitled it, the law of nations in our western orb. These primary rules and fundamental principles should be weighed and compared with the precepts of the law of nature, and the practice of other countries; should be explained by reasons, illustrated by examples, and confirmed by undoubted authorities; their history should be deduced, their changes and revolutions observed, and it should be shewn how far they are connected with, or have at any time been affected by, the civil transactions of the kingdom.
