Adams could see in such parts of the " Grammar" as he could understand, little more than an enlargement of Stallo's book already twenty years old.

亚当斯可以从他能理解的“语法” 的某些部分中看到， 只不过是对已经二十年的史塔洛的书的扩充。

The progress of science was measured by the success of the " Grammar, " when, for twenty years past, Stallo had been deliberately ignored under the usual conspiracy of silence inevitable to all thought which demands new thought-machinery.

科学的进步是以“语法”的成功来衡量的，在过去的二十年里，在所有需要新的思想机器的思想不可避免的通常的沉默阴谋下，斯塔洛一直被故意忽视。
