Newton's analysis of this book, which he made in Cambridge while protecting himself from London's infection , is the most substantial written statement he is known to have made about the plague, according to Bonham's. As far as the therapy is concerned, Newton writes that "the best is a toad suspended by the legs in a chimney for three days, which at last vomited up earth with various insects in it, on to a dish of yellow wax, and shortly after died. Combining powdered toad with the excretions and serum made into lozenges and worn about the affected area drove away the contagion and drew out the poison".
Enlightenment philosophers chose a short history of scientific predecessors—Galileo, Boyle, and Newton principally—as the guides and guarantors of their applications of the singular concept of nature and natural law to every physical and social field of the day.
In this respect, the lessons of history and the social structures built upon it could be discarded. It was Newton's conception of the universe based upon natural and rationally understandable laws that became one of the seeds for Enlightenment ideology. Monboddo and Samuel Clarke resisted elements of Newton's work, but eventually rationalised it to conform with their strong religious views of nature. Newton himself often told the story that he was inspired to formulate his theory of gravitation by watching the fall of an apple from a tree.
Although it has been said that the apple story is a myth and that he did not arrive at his theory of gravity at any single moment,  acquaintances of Newton such as William Stukeley , whose manuscript account of has been made available by the Royal Society do in fact confirm the incident, though not the apocryphal version that the apple actually hit Newton's head. John Conduitt , Newton's assistant at the Royal Mint and husband of Newton's niece, also described the event when he wrote about Newton's life: .
In the year he retired again from Cambridge to his mother in Lincolnshire. Whilst he was pensively meandering in a garden it came into his thought that the power of gravity which brought an apple from a tree to the ground was not limited to a certain distance from earth, but that this power must extend much further than was usually thought. It is known from his notebooks that Newton was grappling in the late s with the idea that terrestrial gravity extends, in an inverse-square proportion, to the Moon; however, it took him two decades to develop the full-fledged theory.
Newton showed that if the force decreased as the inverse square of the distance, one could indeed calculate the Moon's orbital period, and get good agreement.
He guessed the same force was responsible for other orbital motions, and hence named it "universal gravitation". Various trees are claimed to be "the" apple tree which Newton describes.
The King's School, Grantham claims that the tree was purchased by the school, uprooted and transported to the headmaster's garden some years later. The staff of the now National Trust -owned Woolsthorpe Manor dispute this, and claim that a tree present in their gardens is the one described by Newton. A descendant of the original tree  can be seen growing outside the main gate of Trinity College, Cambridge, below the room Newton lived in when he studied there.
The National Fruit Collection at Brogdale in Kent  can supply grafts from their tree, which appears identical to Flower of Kent , a coarse-fleshed cooking variety.

At Newton's birth, Gregorian dates were ten days ahead of Julian dates: thus his birth is recorded as taking place on 25 December Old Style, but can be converted to a New Style modern date of 4 January By the time of his death, the difference between the calendars had increased to eleven days.
Moreover, he died in the period after the start of the New Style year on 1 January, but before that of the Old Style new year on 25 March. His death occurred on 20 March according to the Old Style calendar, but the year is usually adjusted to A full conversion to New Style gives the date 31 March Charles Hutton , who in the late eighteenth century collected oral traditions about earlier scientists, declared that there "do not appear to be any sufficient reason for his never marrying, if he had an inclination so to do.
It is much more likely that he had a constitutional indifference to the state, and even to the sex in general. The Renaissance Mathematicus. Retrieved 20 March United Press International.
