从地质学论文中关于火山的简短说明中，我们可能经常被误导，认为它们是轮廓如此规则的结构，它们的形状表明了它们的性质。在某些情况下，这似乎是非常正确的，因此我想在已经就这个问题写下的意见之外补充几点意见。然而，在其他情况下，火山的形状似乎没有任何区别于其他山脉的特征，这一点可以通过浏览洪堡对南美洲火山的一系列观点来看出。冰岛的山脉也非常崎岖。当我在那个国家旅行时，我看到并登上了许多火山，我不记得它们的形状有什么比它们的陡峭和一般的崎岖更吸引我的注意。像这样的山脉向我们呈现的形式的荒野，显然是许多不同原因的综合结果，因此试图对整体的形成寻求简单的解释是徒劳的。
From the short notices which are to be found about volcanos in treatises on geology, we might often be led into the belief that they were structures so regular in contour that their form was indicative of their nature. In certain cases this appears to be so remarkably true, that I wish to add a few observations to those which have already been written upon the subject. In other cases, however, the form of a volcano does not appear to have any characteristics which distinguish it from other mountains, as will be seen by glancing through the series of views given by Humboldt of the volcanos of South America. The mountains in Iceland are also very rough. When travelling in that country, where I saw and ascended many volcanos, I do not remember that there was anything about their shape more than their steepness and general ruggedness which particularly attracted my attention. The wilderness of form presented to us by such mountains as these is so evidently the combined effect of many and varied causes, that it would be vain to seek a simple explanation for the formation of the whole.
