or milk, he inquires whether there be not something analogous to the formation of the bird in the egg, or to that coagulation of chaos which gave birth to our world. In presence of that impalpable force which makes liquids freeze, he asks if apoplexy and cataract are not the effects of a like power, and do not indicate also the presence of a congealing agency. He is in presence of nature as an artist, a man of letters in presence of a living countenance, marking every feature, every movement of physiognomy, so as to be able to divine the passions and the inner disposition, ceaselessly correcting and undoing his interpretations, kept in agitation by thought of the invisible forces which operate beneath the visible envelope. The whole of the middle-age and of antiquity, with their theories and imaginations, Platonism, Cabalism, Christian theology, Aristotle's substantial forms, the specific forms of the alchemists,— all human speculations, entangled and transformed one within the other, meet simultaneously in his brain, so as to open up to him vistas of this unknown world. The accumulation, the pile, the confusion, the fermentation and the inner swarming, mingled with vapours and flashes, the tumultuous overloading of his imagination and his mind, oppress and agitate him. In this expectation and emotion his curiosity takes hold of everything; in reference to the least fact, the most special, the most obsolete, the most chimerical, he conceives a chain of complicated investigations, calculating how the ark could contain all creatures, with their provision of food; how Perpenna, at a banquet, arranged the guests so as to strike Sertorius; what trees must have grown on the banks of Acheron, supposing that there were any; whether quincunx plantations had not

their origin in Eden, and whether the numbers and geometrical figures contained in the lozenge-form are not met with in all the productions of nature and art. You may recognise here the exuberance and the strange caprices of an inner development too ample and too strong. Archæology, chemistry, history, nature, there is nothing in which he is not passionately interested, which does not cause his memory and his inventive powers to overflow, which does not summon up within him the idea of some force, certainly admirable, possibly infinite. But what completes his picture, what signalises the advance of science, is the fact that his imagination provides a counterbalance against itself. He is as fertile in doubts as he is in explanations. If he sees a thousand reasons which tend to one view, he sees also a thousand which tend to the contrary. At the two extremities of the same fact, he raises up to the clouds, but in equal piles, the scaffolding of contradictory arguments. Having made a guess, he knows that it is but a guess; he pauses, ends with a perhaps, recommends verification. His writings consist only of opinions, given as such; even his principal work is a refutation of popular errors. In the main, he proposes questions, suggests explanations, suspends his judgments, nothing more; but this is enough: when the search is so eager, when the paths in which it proceeds are so numerous, when it is so scrupulous in securing its hold, the issue of the pursuit is sure; we are but a few steps from the truth.

In this band of scholars, dreamers, and inquirers, ap pears the most comprehensive, sensible, originative of the

minds of the age, Francis Bacon, a great and luminous intellect, one of the finest of this poetic progeny, who, like his predecessors, was naturally disposed to clothe his ideas in the most splendid dress: in this age, a thought did not seem complete until it had assumed form and colour. But what distinguishes him from the others is, that with him an image only serves to concentrate meditation. He reflected long, stamped on his mind all the parts and relations of his subject; he is master of it, and then, instead of exposing this complete idea in a graduated chain of reasoning, he embodies it in a comparison so expressive, exact, lucid, that behind the figure we perceive all the details of the idea, like liquor in a fine crystal vase. Judge of his style by a single example:

For as water, whether it be the dew of Heaven or the springs of the earth, easily scatters and loses itself in the ground, except it be collected into some receptacle, where it may by union and consort comfort and sustain itself (and for that cause, the industry of man has devised aqueducts, cisterns, and pools, and likewise beautified them with various ornaments of magnificence and state, as well as for use and necessity); so this excellent liquor of knowledge, whether it descend from divine inspiration or spring from human sense, would soon perish and vanish into oblivion, if it were not preserved in books, traditions, conferences, and especially in places appointed for such matters as universities, colleges, and schools, where it may have both a fixed habitation, and means and opportunity of increasing and collecting itself."1

"The greatest error of all the rest, is the mistaking or misplacing of the last or farthest end of knowledge: for men have entered into a desire of learning and knowledge, sometimes upon a natural curiosity and inquisitive appetite; sometimes to
