"I am rambling about here in the charming thickets of this villa, deliciously asleep, if fancy wake me not now and then with the thunder of the wave beneath your feet. You cannot now stay long from "Yours, ever, "Henry Fuseli." "John Knowles, Esq." The month of September 1818, was passed by me with Fuseli and Mrs. Fuseli at Ramsgate; he was then in excellent health and spirits, and although in his seventy-eighth year, had considerable bodily strength and activity. Our constant practice was, to leave the house about five o'clock in the morning, and sometimes earlier, to walk until eight, breakfast, and employ ourselves during the middle of the day in reading or writing. We walked for an hour before dinner, and did the same in the evening before we retired to rest, the usual hour for which was about ten o'clock. It was at this place that I collated his aphorisms in their present form, under his inspection, and then made a fair copy of them for the press. In the year 1820, he published a quarto volume, containing three additional lectures, reprinted the three which appeared in the year 1801, with some alterations and additions, and wrote an introduction, which he called "A Characteristic Sketch of the Principal Technic Instruction, Ancient and Modern, which we possess." This work was purchased by Mr. Cadell the bookseller, for three hundred pounds. Mr. Bonnycastle, the Professor of Mathematics to the Royal Military College at Woolwich, died this year (1821), in the seventieth year of his age;[58] he had been for more than forty years the intimate friend, occasional companion, and always a great admirer of the talents of Fuseli. Bonnycastle was a mathematician of celebrity, independently of which he had a fine taste for poetry and English literature in general; his memory was retentive, his knowledge extensive, and he was ever ready to communicate what he knew. His conversational talents were of the first order, and he occasionally enlivened his remarks with apposite anecdotes. As he was the friend of my youth, I feel much satisfaction in recording here my gratitude for instruction and many acts of kindness received from this amiable man.
