【参考译文】

首先要感谢凯恩博士的邀请。我虽然不是地质学家，但是收集矿石标本已经有很多年了。这些标本是我从世界各地收集而来的，因而形状各异，彼此差别很大。今天我带来了部分标本，我会先告你你们每一块矿石标本的信息，之后会给大家仔细观察一番。通常来讲，长石是最常见的矿石，而且种类繁多。第一批样本就是正长石。在这里可以看到，它的颜色分布很广，从纯白色到粉红色，再到赤红色，几乎都有。这块有玻璃光泽的正长石是从火山岩的碎屑中找到的，当时我在墨西哥进行矿石样本采集的活动。接下来我要向你们展示的样本是叫做天河石的微斜长石。这种矿石最显著的特征就是它通体的翠绿色。这种矿石可以用来做珠宝，价值相当大。最后的这些样本是斜长石。斜长石是很少见的矿石种类，因为在我所收藏的样本中，这些斜长石样本是我最得意的藏品。此外还有一些个头较大的矿石样本不便携带，因此我做了几张它们的幻灯片。现在请关上灯，我将向你们展示这些可爱的石头。
