There are dates in the margin extending from 1707 to 1719, not in chronological order, which probably indicate the periods when each Lecture was given in the College. The whole is fairly written as if for the press. On the fly-leaf at the end is Lambert's name, and a note that 3 MS. books are for his nephew, Leonard Chappelow. Lambert became Master of the College in 1727. A copy of his will, which was proved 21 Feb., 1734-5, is in Baker's MSS. XXXVI.... 263. He bequeathed all his MSS. and papers in writing to Leonard Chappelow, Arabic Professor, who was one of his executors.
