he Cambridge University was closed until October, year of Sixteen Hundred Sixty-seven. Most of the intervening time Newton spent at the home of his mother, but from accounts of his we can see that the College people kept their eagle-eye upon him, for they sent remittances to him regularly for "commons."
When he returned to Cambridge he was assigned to the "spiritual chamber," which was a room next to the chapel, that had formerly been reserved as a guest-room for visiting dignitaries.
In March, Sixteen Hundred Sixty-eight, he was given the degree of Master of Arts. His studies now were of a very varied kind. He was required to give one lecture a week on any subject of his own choosing. Needless to say his themes were all mathematical or scientific. Just what they were can best be inferred by consulting his cashbook, since the lectures themselves were not written out and all memoranda concerning them have disappeared. This account-book shows that his expenditures were for a Gunter's Book (he who invented the Gunter's Chain), a magnet and a compass, glue, bulbs, putty, antimony, vinegar, white lead, salts of tartar, and lenses.
And in addition there are a few interesting items such as one sees in the Diary of George Washington: "Lost at cards, five shillings." "Treating at tavern, ten shillings." "Binding my Bible, three shillings." "Spent on my cousin, one pound, two." "Expenses for wetting my degree, sixteen shillings."
The last item shows that times have changed but little: this scientist and philosopher par excellence had to moisten his diploma at the tavern for the benefit of good fellows who little guessed with whom they drank.
He also had "poor relations" come to visit him; and it is significant that while there are various items showing where he lost money at cards, there are no references to any money won at the same business, from which we infer that while there was no one at Cambridge who could follow him in his studies, there yet were those who could deal themselves better hands when it came to the pasteboards.
Evidently he got discouraged at playing cards, for after the year Sixteen Hundred Sixty-eight, there are no more items of "treating at the tavern" or "lost at cards." The boys had tried to educate him, but had not succeeded. In card exploitations he fell a victim of arrested development.
I suppose it will not cause any one a shock to be told that "the greatest thinker of all time" was not exactly a perfect man.
So let the truth be known that throughout his life Newton had a well-defined strain of superstitious belief running through his character. He never quite relinquished the idea of transmutation of metals, and at times astrology was quite as interesting to him as astronomy.
