pillars on which his sleep rested: no step must approach his room; and as to light, if he saw but a moonbeam penetrating a crevice of the shutters, it made him unhappy; and, in fact, the windows of his bed-chamber were barricadoed night and day. But now darkness was a terror to him, and silence an oppression. In addition to his lamp, therefore, he had now a repeater in his room; the sound was at first too loud, but, after muffling the hammer with cloth, both the ticking and the striking became companionable sounds to him. At this time (spring of 1803) his appetite began to fail, which I thought no good sign. Many persons insist that Kant was in the habit of eating too much for health. [Footnote: Who these worthy people were that criticised Kant's eating, is not mentioned. They could have had no opportunity of exercising their abilities on this question, except as hosts, guests, or fellow-guests; and in any of those characters, a gentleman, one would suppose, must feel himself degraded by directing his attention to a point of that nature. However, the merits of the case stand thus between the parlies: Kant, it is agreed by all his biographers, ate only once a day; for as to his breakfast, it was nothing more than a very weak infusion of tea, (vide Jachmann's Letters, p. 163,) with no bread, or eatable of any kind. Now, his critics, by general confession, ate their way, from 'morn to dewy eve,' through the following course of meals: 1. Breakfast early in the morning; 2. Breakfast _à la fourchette_ about ten, A.M.; 3. Dinner at one or two; 4. Vesper Brod; 5. Abend Brod; all which does really seem a very fair allowance for a man who means to lecture upon abstinence at night. But I shall cut this matter short by stating one plain fact; there were two things, and no more, for which Kant had an inordinate craving during his whole life; these were tobacco and coffee; and from both these he abstained almost altogether, merely under a sense of duty, resting probably upon erroneous grounds. Of the first he allowed himself a very small quantity, (and everybody knows that temperance is a more difficult virtue than abstinence;) of the other none at all, until the labors of his life were accomplished.] I, however, cannot assent to this opinion; for he ate but once a day, and drank no beer. Of this liquor, (I mean the strong black beer,) he was, indeed, the most determined enemy. If ever a man died prematurely, Kant would say--'He has been drinking beer, I presume.' Or, if another were indisposed, you might be sure he would ask, 'But does he drink beer?' And, according to the answer on this point, he regulated his anticipations for the patient. Strong beer, in short, he uniformly maintained to be a slow poison. Voltaire, by the way, had said to a young physician who denounced coffee under the same bad name of a 'slow poison,' 'You're right there, my friend, however; slow it is, and horribly slow; for I have been drinking it these seventy
