ON A. LAUKENT DE JUSSIP:U. 69 



corresponding parts changing also ; and the reason of this 

 strict agreement between all the modifications of the anim;d 

 economy is evident, for the principle of the subordination of 

 the organs, becomes in animal life, the very principle of the 

 condition of existence itself. 



Thus, by its application to Zoology, the science of charac- 

 ters took a new flight. The Method has become complete, 

 by generalizing itself and extenditig from the one organized 

 kingdom to the other; and even our two authors, who, when 

 compared, exhibit distinct traits, may yet be said to complete 

 each other. M. de Jussieu is the fitter man to follow out the 

 continuous chain of details with persevering patience and 

 indefatigable sagacity, M, Cuvier the better adapted to reach 

 the final consequences with rapid flight; the former is con- 

 stituted to shrink from no difficulties in the pursuit of exper- 

 iment (and this is the only means now applicable to Botany), 

 the other to survey at a glance that reasoning process which 

 best befits the science of Zoology ; both having given a new 

 impulse to the human mind, the impulse of Method, which, 

 (consisting in the union of objects by the qualities they pos- 

 sess in common to one another), is, in fact, to the sciences of 

 observation, what analysis, or the art of reducing them to 

 their distinct elements, is to the experimental sciences. 



And in the same way that analysis, which took its origin 

 in the experiments of Galileo, has gradually passed from the 

 physical sciences to that of the mind, (becoming the Philoso- 

 phical Jnal'jsis of CondiWac), so does Method, the off'spring 

 of the researches of modern Naturalists, await to produce 

 all its effects, the abstract study of the philosopher. And 

 then, and not till then, General Philosophy, \\h\ch springs no 

 less from the much neglected science of classifying ideas, 

 than the deeply studied art of unravelling them, shall become 

 complete. 



M. de Jussieu had published his work, as above stated, in 

 1789. The much confinement to his cabinet which such a 

 production entailed, permitted him to remain in a happy 

 comparative iirnorance of the political movements which were
