brought up by the cook on the proclamation of the three quarters. Kant hurried with it to the eating-room, poured out his _quantum_, left it standing in readiness, covered, however, with paper, to prevent its becoming vapid, and then went back to his study, and awaited the arrival of his guests, whom to the latest period of his life he never received but in full dress. Thus we come round again to dinner, and the reader has now an accurate picture of the course of Kant's day; the rigid monotony of which was not burthensome to him; and probably contributed, with the uniformity of his diet, and other habits of the same regularity, to lengthen his life. On this consideration, indeed, he had come to regard his health and his old age as in a great measure the product of his own exertions. He spoke of himself often under the figure of a gymnastic artist, who had continued for nearly fourscore years to support his balance upon the slack-rope of life, without once swerving to the right or to the left. In spite of every illness to which his constitutional tendencies had exposed him, he still kept his position in life triumphantly. However, he would sometimes observe sportively, that it was really absurd, and a sort of insult to the next generation for a man to live so long, because he thus interfered with the prospects of younger people. This anxious attention to his health accounts for the great interest which he attached to all new discoveries in medicine, or to new ways of theorizing on the old ones. As a work of great pretension in both classes, he set the highest value upon the theory of the Scotch physician Brown, or (as it is usually called, from the Latin name of its author,) the Brunonian Theory. No sooner had Weikard adopted [Footnote: This theory was afterwards greatly modified in Germany; and, judging from the random glances which I throw on these subjects, I believe that in this recast it still keeps its ground in that country.] and made it known in Germany, than Kant became familiar with it. He considered it not only as a great step taken for medicine, but even for the general interests of man, and fancied that in this he saw something analogous to the course which human nature has held in still more important inquiries, viz.: first of all, a continual ascent towards the more and more elaborately complex, and then a treading back, on its own steps, towards the simple and elementary. Dr. Beddoes's Essays, also, for producing by art and curing pulmonary consumption, and the method of Reich for curing fevers, made a powerful impression upon him; which, however, declined as those novelties (especially the last) began to sink in credit. As to Dr. Jenner's discovery of vaccination, he was less favorably disposed to it; he apprehended dangerous consequences from the absorption of a brutal miasma into the human blood, or at least into the lymph; and at any rate he thought, that, as a guarantee
