The duke was surprised, and having a taste for the sciences, he entered into conversation with the young mathematician. He proposed several inquiries, and was astonished at the force, the accuracy and the clearness of his answers. "But how," said the duke, "came you by the knowledge of all these things?" Stone replied, "A servant taught me to read ten years since. Does one need to know anything more than the twenty-six letters, in order to learn everything else that one wishes?"
The duke's curiosity was now greatly increased, and he sat down upon a bank and requested a detail of the whole process by which he had acquired such knowledge. "I first learned to read," said Stone; "afterwards, when the masons were at work at your house, I approached them one day, and observed that the architect used a rule and compass, and that he made calculations. I inquired what might be the meaning and use of these things; and I was informed that there was a science called arithmetic. I purchased a book of arithmetic, and studied it. I was told that there was another science, called geometry. I bought the necessary books, and learned geometry.
"By reading, I found there were good books on these two sciences in Latin; I therefore bought a dictionary and learned Latin. I understood, also, that there were good books of the same kind in French; I bought a dictionary and learned French; and this, my lord, is what I have done. It seems to me that we may learn everything when we know the twenty-six letters of the alphabet."
Under the duke's patronage, Stone rose to be a very considerable mathematician, and was elected a member of the Royal Society of London, in 1725. He seems to have lost the favor of the Duke of Argyle, for, in the latter part of his life, he gave lessons in mathematics, and at last died in poverty.
RICHARD EVELYN.
John Evelyn, a very learned English writer, was born in 1620, and died in 1706. He published several works, all of which are valuable. His treatises upon Natural History are greatly valued. He kept a diary, which has been published, and which contains much that is interesting. Of one of his children, who died early, he gives us the following account:
"After six fits of ague, died, in the year 1658, my son Richard, five years and three days old, but, at that tender age, a prodigy of wit and understanding; for beauty of body, a very angel; for endowment of mind, of incredible and rare hopes. To give only a little taste of some of them, and thereby glory to God:
"At two years and a half old, he could perfectly read any of the English, Latin, French, or Gothic letters, pronouncing the three first languages exactly. He had, before the fifth year, not only skill to read most written hands, but to decline all the nouns, conjugate the verbs regular and most of the irregular; learned Pericles through; got by heart almost the entire vocabulary of Latin and French primitives and words, could make congruous syntax, turn English into Latin, and vice versa, construe and prove what he read, and did the government and use of relative verbs, substantives, ellipses, and many figures and tropes, and made a considerable progress in Comenius's Janua; began himself to write legibly, and had a strong passion for Greek.
