Famous Men of Science

by Sarah Knowles Bolton

Of this time he says, "The three years which I spent at Cambridge were wasted, as far as the academical studies were concerned, as completely as at Edinburgh and at school. I attempted mathematics, and even went during the summer of 1828 with a private tutor (a very dull man) to Barmouth, but I got on very slowly. The work was repugnant to me, chiefly from my not being able to see any meaning in the early steps in algebra." He found great delight in Paley's "Evidences of Christianity," and his "Moral Philosophy."

At Cambridge, like Humboldt, he formed a rare friendship, which helped towards his subsequent success. Professor Henslow was an ardent scholar, a devoted Christian, and a man of most winning manners and good temper. From his great knowledge of botany, entomology, chemistry, mineralogy, and geology, he became a most attractive person to young Darwin, whose especial passion seemed to be the collecting of beetles. Henslow soon became equally fond of Darwin, and the two took long walks together daily, Darwin being known as "the man who walks with Henslow."

Darwin said of this model teacher, years afterward, "He had a remarkable power of making the young feel completely at ease with him; though we were all awe-struck with the amount of his knowledge. Before I saw him, I heard one young man sum up his attainments by simply saying that he knew everything. When I reflect how immediately we felt at ease with a man older, and in every way immensely our superior, I think it was as much owing to the transparent sincerity of his character as to his kindness of heart, and, perhaps, even still more to a highly remarkable absence in him of all self-consciousness. One perceived at once that he never thought of his own varied knowledge or clear intellect, but solely on the subject in hand.

"Another charm which must have struck every one was that his manner to old and distinguished persons and to the youngest student was exactly the same; and to all he showed the same winning courtesy. He would receive with interest the most trifling observation in any branch of natural history, and, however absurd a blunder one might make, he pointed it out so clearly and kindly that one left him no way disheartened, but only determined to be more accurate the next time.

"His lectures on botany were universally popular, and as clear as daylight. So popular were they that several of the older members of the University attended successive courses. Once every week he kept open house in the evening, and all who cared for natural history attended these parties, which, by thus favoring intercommunication, did the same good in Cambridge, in a very pleasant manner, as the scientific societies do in London.... This was no small advantage to some of the young men, as it stimulated their mental activity and ambition....

"During the years when I associated so much with Professor Henslow, I never once saw his temper even ruffled. He never took an ill-natured view of any one's character, though very far from blind to the foibles of others. It always struck me that his mind could not be even touched by any paltry feeling of vanity, envy, or jealousy. With all this equability of temper and remarkable benevolence, there was no insipidity of character. A man must have been blind not to have perceived that beneath this placid exterior there was a vigorous and determined will. When principles came into play, no power on earth could have turned him one hair's breadth....

"Reflecting over his character with gratitude and reverence, his moral attributes rise, as they should do in the highest character, in preëminence over his intellect."

Through this noble friend, Darwin had the opportunity of taking a five years' voyage in the ship Beagle, as a naturalist. The bark, of two hundred and thirty-five tons, under command of Captain Fitz-Roy, was commissioned by government to survey Patagonia, Tierra del Fuego, the shores of Chili, Peru, and some islands in the Pacific, "and to carry a chain of chronometrical measurements round the world."

Professor Henslow knew the captain, and recommended his young friend for the position. Darwin had read Humboldt's travels eagerly, and was delighted with the prospect of a journey like this.

Dr. Darwin was opposed at first, but finally said, "If you can find any man of common sense who advises you to go, I will give my consent." Young Darwin at once visited his uncle, Josiah Wedgwood, at Maer, who approved of the journey, and soon convinced Dr. Darwin of the wisdom of it.
