Well versed in the theory of classification, he was poorly versed in its practical application, and I doubt that he could tell a sperm whale from a baleen whale!

但其中一只名叫孟禄号的捕鲸船船长，知道尼德·兰在我们船上。要请他帮忙，追捕已经发现了的一条鲸鱼。

and it took a truly crafty baleen whale or an exceptionally astute sperm whale to elude the thrusts of his harpoon.

要不是一条狡猾的长须鲸，或是特殊聪明的大头鲸，是很难躲过他的鱼叉的。
