A lighter and runny air liquide was used for new wounds a darker and stickier fluid for old ones.

更轻更稀的液化空气用于新伤口 深色更粘稠的液体用于旧伤口。

Is it not said, that, if a thing be really white, it may be steeped in a dark fluid without being made black.

不曰白乎，涅而不缁。

A small quantity of a dark fluid remained in the saucepan, and an empty cup and saucer that had been drunk out of stood near it.

平底锅里还残留着少量黑色液体， 旁边放着一个喝过的空杯子和碟子。
