Therefore the genuineness of a fossil human relic of the quaternary period seemed to be incontestably proved and admitted.

因此，第四纪类遗迹化石的真实性似乎已得到无可争议的证明和承认。

In a recent paper of his own he tried to calculate how many stable crystals incorporating four chemical elements (so-called quaternaries) might be potentially manufacturable.

在他自己最近的一篇论文，他试图计算有多少含有四种化的稳定晶体(所谓的季盐化合物)可以被制造出来。

In some books, too, you will find the tertiary and quaternary taken out and replaced by periods of different lengths called the Palaeogene and Neogene.

在有的书里，你还会发现不用第三纪和第四纪，而是用不同长度的系来取而代之，称做下第三系和上第三系。
