"EXPLICIT L'ORDRE DE CHEVALRIE.

"After this follows our Author's translation of Dr Bonet's Book of Government of Princes, which is a translation of Aristotle's Politics, and contains 40 Chapters, with a Prologue, shewing into how many languages it had been translated, and how it was first found in the Temple of the Sun, built by Esculapius. Then follows a translation of King Alexander the Great's letter to Aristotle, after his conquest of Persia, with Aristotle's answer, and two other letters of King Alexander's and Aristotle's."

The Manuscript, of which the preceding was an analysis, is not mentioned in any more recent work, and as it could not be traced in any public repository, it was considered to be irrecoverably lost. But in the "Catalogue of the Library at Abbotsford," printed in 1838, at page 232, there occurs the following title:—

"Here begynnys the buke call't the Buke of the Law of Armys, the quhilk was compilit be a notable man, Doctour in Decrees, callit Bennet, prioure of Sallan, &c. MS. fol."

This title attracted the notice of Mr Laing, Secretary of the Bannatyne Club, who conjectured it might prove to be a copy of the work described by Mackenzie. To ascertain this point, he made an application for the use of the volume, through Isaac Bayley, Esq.; which being courteously granted, it was no difficult matter to perceive that this was the identical Manuscript which Dr George Mackenzie had possessed. As the volume itself furnishes no indication on this head, we can only conjecture that it may have fallen into Sir Walter Scott's hands, either by purchase at a sale, or as a present from some of his friends. But we may conclude, that had Sir Walter been aware of the peculiar interest and curiosity of the volume, he would have pointed it out, and some use of it have been made during the latter period of his life.

The Manuscript in question is a large folio of 132 leaves,[[4]] on lombard paper, written in a very distinct hand, about the end of the 15th century. It is in the original wooden boards, in perfect preservation, and contains, repeated in different parts of the volume, autograph signatures of "W. Sanclair of Roislin," "Oliver Sinclar of Rosling, knycht," and "W. Sanclair of Roislin, knecht."

It consists of three distinct works:—

III. The Buke of Batailles.

III. The Buke of the Order of Knyghthede.

III. The Buke of the Governance of Princes.
