   Although chemistry had come a long way in the century that separated Newton and Boyle from Scheele and Priestley and Henry Cavendish, it still had a long way to go. Right up to the closing years of the eighteenth century (and in Priestley's case a little beyond) scientists everywhere searched for, and sometimes believed they had actually found, things that just weren't there: vitiated airs, dephlogisticated marine 1 acids, phloxes, calxes, terraqueous exhalations, and, above all, phlogiston, the substance that was thought to be the active agent in combustion 2. Somewhere in all this, it was thought, there also resided a mysterious elan vital, the force that brought inanimate objects to life.


  从牛顿和玻义耳,到金勒、普里斯特利和亨利·卡文迪许,中间隔着一个世纪。在这个世纪里,化学得到了长足的发展,但还有很长的路要走。直到18世纪的最后几年(就普里斯特利而言,还要晚一点),各地的科学家们还在寻找——有时候认为真的已经发现——完全不存在的东西:变质的气体、没有燃素的海洋酸、福禄考、氧化钙石灰、水陆气味,尤其是燃素。当时,燃素被认为是燃烧的原动力。他们认为,在这一切的中间,还存在一种神秘的生命力,即能赋予无生命物体生命的力。
  No one knew where this ethereal essence lay, but two things seemed probable: that you could enliven it with a jolt 3 of electricity (a notion Mary Shelley exploited to full effect in her novel Frankenstein ) and that it existed in some substances but not others, which is why we ended up with two branches of chemistry: organic (for those substances that were thought to have it) and inorganic 4 (for those that did not).
  谁也不知道这种难以捉摸的东西在哪里,但有两点是可信的:其一,你可以用电把它激活(玛丽·谢利在她的小说《弗兰肯斯泰因》里充分利用了这种认识);其二,它存在于某种物质,而不存在于别的物质。这就是化学最后分成两大部分的原因:有机的(指被认为有那种东西的物质)和无机的(指被认为没有那种东西的物质)。
