This may seem a strange mode of speaking about the reading of a parish clerk—a man in rusty spectacles, with stubbly hair, a large occiput, and a prominent crown.

这似乎是一种奇怪的谈论教区书记阅读的方式——一戴着锈迹斑斑的眼、短发、大枕骨和突出头冠的人。

Let the occiputs, thus cut off, be interchanged, applying each to the head of his opposite party-man.

让这些被割下的后脑勺互换位置，后脑勺安到对方政党的成员头上。
