It appeared to have been fitted up as a chemical laboratory.

这间屋子收拾得好象是化学试验室。

Near the farther end a low arched passage branched away from it and led to the chemical laboratory.

靠着走廊尽头上有一个低低的拱形过道，从这里一直通往化验室。

And who was the first? I asked. A fellow who is working at the chemical laboratory up at the hospital.

头一个是谁？是一个在医院化验室工作的。
