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. When his brother was disposed of, he came to supper, and I thought that he looked at Mrs. Darwin as if he was somewhat surprised when he heard that I had passed the whole evening in her company. After she withdrew, he entered into conversation with me upon the carriage that I had made, and upon the remarks that fell from some members of the Society to whom I had shewn it. I satisfied his curiosity; and having told him that my carriage was in the town, and that he could see it whenever he pleased, we talked upon mechanical subjects, and afterwards on various branches of knowledge, which necessarily produced allusions to classical literature; by these, he discovered that I had received the education of a gentleman. 'Why! I thought,' said the Doctor, 'that you were a coach-maker!' 'That was the reason,' said I, 'that you looked surprised at finding me at supper with Mrs. Darwin. But you see, Doctor, how superior in discernment ladies are even to the most learned gentlemen: I assure you that I had not been in the room five minutes before Mrs. Darwin asked me to tea!'" These endeavours to improve the construction of carriages were near costing him dear; nor did he desist till he had been several times thrown down, and at last broke the pan of the right knee, which occasioned a slight but incurable lameness. The amiable woman, of whom Mr. Edgeworth has here spoken, died in 1770. Of the five children whom she brought him, two were lost in their infancy. Charles, the eldest of the remaining three, died at Edinburgh, in 1778, of a disease supposed to be communicated by a corpse which he was dissecting, when one of his fingers was slightly wounded. He had obtained a gold medal for pointing out a test by which pus might be distinguished from mucus; and the Essay in which he had stated his discovery was published by his father after his death, together with another treatise, which he left incomplete, on the Retrograde Motions of the Absorbent Vessels of Animal Bodies in some Diseases. Another of his sons, Erasmus, who was a lawyer, in a temporary fit of mental derangement put an end to his existence, in 1799. Robert Waring, a physician, now in high reputation at Shrewsbury, is the only one of these children who survived him.
