PITTSIftIR6I4S4ETTE. . • The Alehemista , or the hiiddle'Agea. Since the works of Hallam.and Maitland have been'given'tp the modern world, and a host of drennts,-,and cartunnies in .regard to the Middle Ages 'have been dispelled, there have not hem& wanting a considerable number of andill 'minds among the Anglo •Baxons, and &still more numerous corps of patierik' and toiling titudents in Germany, dihoha:vedevoted themselves, some nut of an' antiquarian taste, others. by reason of the inviting, because unexplored nature of tho field; and. many through rziligions zeal, the investigation of the historical, lite ,raty and scientific moninnents of that period.: That class Of conceited talkers, -4,• ""ek„..relie think no man can lie truly learned, or great who does • not spoilt • , r,•V- everlastingly-about the.dog Lutiu, univer sal ignorance, immeasurable stupidity, and vast anperstitioa of the Dark Ages, is hap : • pity diminishing liefute the results of re ' 1 cent historical investigation,t, which have I proved that in..manyreapeete; if they are dark,, it is only in the same sense no form :I,: and color have no existence to the blind man.. Ages Would ,scarcely be termed dark which 'produced such men as A.nseltn, Bernard, and the Drintor of Arpin ; and ::-- though perhaps all the world entertained : erroneous opinions on the. shape of the globe, gravitation, and solar attraction, we should ourselves remember that our own theory on these paints is only a theory - , after all, though uudoubtedly the most consonant with natural phenomena which haft yet been started. • . ..! liotbing, perhaps, in the .h i story of the medirevaliserital,.has awakened more ridi f cede, pity and contempt., than the belief in the oxi.steno of the ~ p hilosophers bone. We are glad to have at hand an extract from is work of the gteat chemist, Liebig, in defense of the alchemists, which will be read with interest. It is from his 'Chem , : int Lettere," which have just been trans lated and published in England: .• "In the first stage of the development of science, the alchemists could not possi. bly Gave any other notions of the' nature of metals than these which they actually held. -No'others were admissible, or even passible; and their views were consequent ly,. by natural laws, inevitable. Without • these ideartiehemistrywoild not now stand itkpresent perfection; and in order to • roil the science into existence, and in the ' • course: of fifteen bandied Or two theusand years to bring it to the point which it has now reached, it wound have been necessary to create .the science anew. We hear ii said that the idea of a philosopher's stone • ~ was an enter; but, all our view. have been develoPe4)•:from errors, and that which ,• ," to-day we regard art truth in chemistry, may, perhaps, before to-morrow, be rese t .. Hired as ithillacy. theory- which very eeryurges men r., hiisw exeih2a aeurene, and - 4 1 1,4. -??*'Pei' 6l 'cet'itiet, is a gam ro s reen „,, 4bitttsis Mbar and roseareh which sad u, dislaveties.. The tbret; laa-v of Kepler, -.:Mich are regarded as the toundation of modern astronomy,. were.uot derived (pun ▪ just views of the nature of thatloree which retains the planets in their revolutions and in their - -orbit,, but ate - simply deduction, obtained by , the art of experimenting; that I is to ray,, by labor and research. I .: • Mast lively imagniatian, the most a¢ut. intellect,: is not capabre of devising a M? . .therttglit which could have acted more pow and * constantly on the minds and faotiltae of• Men,. than that ivery idea of thuPhilosopher's stone. It Irak that same . .tareti'vehich urged - thousands of adventu feta, with and:after Columbus, to venture fortune atitllife on the discovery of a new world and which, in our day, drives hun • dreds of thousands to cross the mountain, of Westenit America, and thus to spread and civilization over that hith erto neglected part of,the globe. t "In order to know that the philosopher's • ,siene'did not really chat, it is indispensable that &Very -substance accessible to study and 'Observation - •shauld be phserred and axeuthied, in accordance with the scientific resources of the time.- But it is precisely in this that se perceive the almost miracti . lotus influence of the idea. The strength of the opinion could not be broken till science bad 4 .o 4obOdteeertain stage of development.
