Note 84 — CHAPTER THE THIRD. CONSTANTINE THE SECOND—A. D. 900-943.

Chron. Sax. 949. Innes, Ap. 3. The seventh year of Malcolm corresponds exactly with 949, the year in which Olave reappeared in Northumbria, and the curious tradition preserved in the old chronicle that Constantine resumed his authority for a week to head the Scottish army in an incursion to the Tees, must surely be connected with the arrival of his son-in-law, and the reluctance of Malcolm to break the engagement by which he held Cumberland.
