Gregory’s plan was that the teaching should be given in English, which was certainly a sensible proposal, that the undergraduates should study some Euclid, trigonometry, algebra, mechanics, catoptrics, and dioptrics, astronomy, the theory of the planets and navigation. ‘The teacher,’ he said, ‘should be always ready to gratify the request of those who desire his instruction. If possible, the students should have a printed book on the subject; if not, the lecturer will take care timeously to give those of the class proper notes to be written by them. And lastly, if any students were found hungering and thirsting, they were to be given regular demonstrations of the operations of integers, or fractions, vulgar or decimal—when they pleased.’ As to the proper numbers for a class, Gregory said they should be not less than ten and not more than twenty. The course here touched on was described very fully in the paper sent to Mr Pepys, and Mr Pepys’ answer is rather refreshing. ‘REVEREND SIR, ... As little qualified as I truly am, for offering aught upon a scheme digested with the thoughtfulness and skill of its learned author, legible in every line of it, the terms nevertheless wherein you require my opinion and advice concerning it, joined with the dignity of its subject and quality of the persons for whom it is calculated, are so forcible, that I cannot omit observing to you my missing two things.... First—_Music_—a science peculiarly productive of a pleasure that no state of life, public or private, secular or sacred, no difference of age or season, no temper of mind, or condition of health exempt from present anguish, nor, lastly, distinction of quality, render either improper, untimely, or unentertaining.[3] My other want is what possibly may be thought of less weight; but what nevertheless holds no lower a place with me on this occasion (whether for ornament, delight, solid use, or ease of carriage both at home and abroad), than any other quality a gentleman can bear about him, though none less thought on, or (which is more) of less difficulty in the attaining ... I mean Perspective: not barely as falling within the explication of vision, or serving only to the laying down of objects of sight, but with the improvement of it, to the enabling our honourable student gracefully to finish and embellish the same, with its just heightenings and shadowings, as far as expressible in black and white; thereby when in foreign travels to know how by his own skill to entertain himself in taking the appearances of all he meets with, as remarkable, whether of palaces or of other fabrics, ruins, fortifications, ports, moles, or other public views.’ Footnote 3: Mr Pepys, who, as we know from his Diary as well as from Evelyn, was skilled in music, had thus an opportunity of expressing his views on that subject.
