In 1781, he married his second wife, the widow of Colonel Pole, of Radburne, near Derby, with whom he appears to have lived as happily as he had done with his first. By her persuasion, he was induced to pass the latter part of his days at Derby. Here his medical practice was not at all lessened; and he had a second family to provide for out of the emolument which it brought him. His other publications were a Tract on Female Education, a slight performance, written for the purpose of recommending a school kept by some ladies, in whose welfare his relation to them gave him a warm interest; and a long book in 1800, on the Philosophy of Agriculture and Gardening, which he entitled Phytologia. On Lady Day, 1802, he took possession of an old house, called the Priory, which had belonged to his son Erasmus, and was situated at a short distance from Derby; and on the 17th of the next month, while he was writing to his friend, Mr. Edgeworth, the following letter, he was arrested by the sudden approach of death. * * * * * Priory, near Derby, April 17, 1802. Dear Edgeworth,--I am glad to find that you still amuse yourself with mechanism, in spite of the troubles of Ireland. The use of turning aside, or downwards, the claw of a table, I don't see, as it must be reared against a wall, for it will not stand alone. If the use be for carriage, the feet may shut up, like the usual brass feet of a reflecting telescope. We have all been now removed from Derby about a fortnight, to the Priory, and all of us like our change of situation. We have a pleasant home, a good garden, ponds full of fish, and a pleasing valley somewhat like Shenstone's--deep, umbrageous, and with a talkative stream running down it. Our home is near the top of the valley, well screened by hills from the east and north, and open to the south, where at four miles' distance we see Derby Tower. Four or more strong springs rise near the house, and have formed the valley, which, like that of Petrarch, may be called Valchiusa, as it begins, or is shut at the situation of the house. I hope you like the description, and hope farther, that yourself or any part of your family will sometime do me the pleasure of a visit. Pray tell the authoress that the water-nymphs of our valley will be happy to assist her next novel. My bookseller, Mr. Johnson, will not begin to print the Temple of Nature till the price of paper is fixed by Parliament. I suppose the present duty is paid * * * * * To this imperfect sentence was added on the opposite side by another hand;
