It was in 1765, while stopping at Chester and examining a mechanical exhibition there, that Edgeworth first heard of Dr. Darwin, who had lately invented a carriage which could turn in a small compass without danger of upsetting. Richard on hearing this determined to try his hand on coach building, and had a handsome phaeton constructed upon the same principle; this he showed in London to the Society for the Encouragement of Arts, and mentioned that he owed the original idea to Dr. Darwin. He then wrote to the latter describing the reception of his invention, and was invited to his house. The doctor was out when he arrived at Lichfield, but Mrs. Darwin received him, and after some conversation on books and prints asked him to drink tea. He discovered later that Dr. Darwin had imagined him to be a coachmaker, but that Mrs. Darwin had found out the mistake. 'When supper was nearly finished, a loud rapping at the door announced the doctor. There was a bustle in the hall, which made Mrs. Darwin get up and go to the door. Upon her exclaiming that they were bringing in a dead man, I went to the hall: I saw some persons, directed by one whom I guessed to be Dr. Darwin, carrying a man, who appeared motionless. "He is not dead," said Dr. Darwin. "He is only dead drunk. I found him," continued the doctor, "nearly suffocated in a ditch; I had him lifted into my carriage, and brought hither, that we might take care of him to-night." Candles came, and what was the surprise of the doctor and of Mrs. Darwin to find that the person whom he had saved was Mrs. Darwin's brother! who, for the first time in his life, as I was assured, had been intoxicated in this manner, and who would undoubtedly have perished had it not been for Dr. Darwin's humanity.

'During this scene I had time to survey my new friend, Dr. Darwin. He was a large man, fat, and rather clumsy; but intelligence and benevolence were painted in his countenance. He had a considerable impediment in his speech, a defect which is in general painful to others; but the doctor repaid his auditors so well for making them wait for his wit or his knowledge, that he seldom found them impatient.'

At Lichfield he met Mr. Bolton of Snow Hill, Birmingham, who asked him to his house, and showed him over the principal manufactories of Birmingham, where he further improved his knowledge of practical mechanics. His time was now principally devoted to inventions; he received a silver medal in 1768 from the Society of Arts for a perambulator, as he calls it, an instrument for measuring land. This is a curious instance of the changed use of a word, as we now associate perambulators with babies. In 1769 he received the Society's gold medal for various machines, and about this time produced what might have been the forerunner of the bicycle, 'a huge hollow wheel made very light, withinside of which, in a barrel of six feet diameter, a man should walk. Whilst he stepped thirty inches, the circumference of the large wheel, or rather wheels, would revolve five feet on the ground; and as the machine was to roll on planks, and on a plane somewhat inclined, when once the vis inertia of the machine should be overcome, it would carry on the man within it as fast as he could possibly walk. … It was not finished; I had not yet furnished it with the means of stopping or moderating its motion. A young lad got into it, his companions launched it on a path which led gently down hill towards a very steep chalk-pit. This pit was at such a distance as to be out of their thoughts when they set the wheel in motion. On it ran. The lad withinside plied his legs with all his might. The spectators who at first stood still to behold the operation were soon alarmed by the shouts of their companion, who perceived his danger. The vehicle became quite ungovernable; the velocity increased as it ran down hill. Fortunately, the boy contrived to jump from his rolling prison before it reached the chalk-pit; but the wheel went on with such velocity as to outstrip its pursuers, and, rolling over the edge of the precipice, it was dashed to pieces.

'The next day, when I came to look for my machine, intending to try it upon some planks, which had been laid for it, I found, to my no small disappointment, that the object of all my labours and my hopes was lying at the bottom of a chalk-pit, broken into a thousand pieces. I could not at that time afford to construct another wheel of that sort, and I cannot therefore determine what might have been the success of my scheme.'

He goes on to say: 'I shall mention a sailing carriage that I tried on this common. The carriage was light, steady, and ran with amazing velocity. One day, when I was preparing for a sail in it with my friend and schoolfellow, Mr. William Foster, my wheel-boat escaped from its moorings just as we were going to step on board. With the utmost difficulty we overtook it; and as I saw three or four stage-coaches on the road, and feared that this sailing chariot might frighten their horses, I, at the hazard of my life, got into my carriage while it was under full sail, and then, at a favourable part of the road, I used the means I had of guiding it easily out of the way. But the sense of the mischief which must have ensued if I had not succeeded in getting into the machine at the proper place, and stopping it at the right moment, was so strong, as to deter me from trying any more experiments on this carriage in such a dangerous place.'

I have already given the changed use of the word perambulator. As an example of the different use of a word in the last century, I may mention telegraph, by which he means signalling either by moving wooden arms or by showing lights. This mode of conveying a message he first applied in order to win a wager: 'A famous match was at that time pending at Newmarket between two horses that were in every respect as nearly equal as possible. Lord March, one evening at Ranelagh, expressed his regret to Sir Francis Delaval that he was not able to attend Newmarket at the next meeting. "I am obliged," said he, "to stay in London; I shall, however, be at the Turf Coffee-house; I shall station fleet horses on the road to bring me the earliest intelligence СКАЧАТЬ
