incorporated in the Digest. (Sm. Dict. Antiq.) Four volumes by Lord Coke, published A. D. 1628. The first is an extensive comment upon a treatise on tenures, compiled by Littleton, a judge of the Common Pleas, temp. Edward IV. This comment is a rich mine of valuable common law learning, collected and heaped together from the ancient reports and year-books, but greatly defective in method. It is usually cited by the name of "Co. Litt.," or, as "1 Inst." The second volume is a comment upon old acts of parliament, without systematic order; the third a more methodical treatise of the pleas of the crown; and the fourth an account of the several species of courts. These are cited as "2," "3," or "4 Inst.," without any author's name. 1 Bl. Com. 73. INSTITUTIO HÆREDIS. - In the Roman law, the appointment of the hæres in the will. It corresponds very nearly to the nomination of an executor in English law. Without such an appointment the will was void at law, but the prætor (i. e. equity) would, under certain circumstances, carry out the intentions of the testator. Brown. It was, therefore, necessary to prepare an elementary treatise, and the Institutes were pub. lished a month before the Pandects, A. D. 533, and designed as an elementary introduction to legal study (legum cunabula.) The work was divided into four books, subdivided into titles. The Institutes are the elements of the Roman law, and were composed, at the command of the Emperor Justinian, by Trebonian, Dorotheus, and Theophilus, who took them from the writ ings of the ancient lawyers, and chiefly from those of Gaius, especially from his Institutes and his books called Aureorum, (i. e. of important matters.)-Wharton.
