to progress in the study of human knowledge; and those who reflect upon the nature of the difficulties they find in their studies of languages, history, or sciences, will easily guess the rapidity with which they could overcome these difficulties if they could themselves execute the above four performances; for, of what does principally consist the task of learning a foreign language? In nothing but in committing to memory some thousands of words forming tables like that of experiment 3d; and next, in becoming familiar with a few dozens of grammatical paradigmas, constituting tables like that of experiment 2d. One will be a very good historian if he can enumerate facts after facts written out in a table of shape 1st. Experiment 4th is visibly the problem to be solved in the study of chronology, a knowledge so useful but so rarely possessed even by the learned, because so difficult in the usual routine of study. With regard to geography and statistics, every one knows that they are nothing but a pile of similar tables. Mathematical studies are all easily reducible; 1st, to a series of problems, each problem being a series of minor operations to be recollected. These two series may be written out exactly in the form of Nos. 1 and 2; and 2dly, to a series of theorems, or, rather, equations, which will easily be learned by those who can manage tables like that of No. 3.
The physician may reduce almost all his studies into similar tables. We will remind him of one of the most important; viz., the Diagnostic part. Here he has to commit to his memory a number of tables, all exactly of the shape of No. 2; and we will hereafter convince him that anatomy, physiology, materia-medica, &c., are nothing but a heap of registers, not in the least differing from the above four tables: very long and numerous they are, we
