His very last excursion was in August of this year, (1803,) not to my cottage, but to the garden of a friend. But on this day he manifested great impatience. It had been arranged that he was to meet an old friend at the gardens; and I, with two other gentlemen, attended him. It happened that _out_ party arrived first; and such was Kant's weakness, and total loss of power to estimate the duration of time, that, after waiting a few moments, he insisted that some hours had elapsed--that his friend could not be expected--and went away in great discomposure of mind. And so ended Kant's travelling in this world. In the beginning of autumn the sight of his right eye began to fail him; the left he had long lost the use of. This earliest of his losses, by the way, he discovered by mere accident, and without any previous warning. Sitting down one day to rest himself in the course of a walk, it occurred to him that he would try the comparative strength of his eyes; but on taking out a newspaper which he had in his pocket, he was surprised to find that with his left eye he could not distinguish a letter. In earlier life he had two remarkable affections of the eyes: once, on returning from a walk, he saw objects double for a long space of time; and twice he became stone-blind. Whether these accidents are to be considered as uncommon, I leave to the decision of oculists. Certain it is, they gave very little disturbance to Kant; who, until old age had reduced his powers, lived in a constant state of stoical preparation for the worst that could befall him. I was now shocked to think of the degree in which his burthensome sense of dependence would be aggravated, if he should totally lose the power of sight. As it was, he read and wrote with great difficulty: in fact, his writing was little better than that which most people can produce as a trial of skill with their eyes shut. From old habits of solitary study, he had no pleasure in hearing others read to him; and he daily distressed me by the pathetic earnestness of his entreaties that I would have a reading-glass devised for him. Whatever my own optical skill could suggest, I tried; and the best opticians were sent for to bring their glasses, and take his directions for altering them; but all was to no purpose.
