"Do you drink it?"
"Not in every case, not with housemaid's knee or sore throat, anyway. You paint it in the throat or on the knee. Here, we'd better put you in a camel's hairbrush."
"Good. And what's nitrate of potash for?"
"Well, if you have an inflamed eye, put a spot or two in this eye-cup, fill it up with water and blink into it—like this."
"Thanks. And what do you use chlorodyne for?"
"Bad pains in the stomach."
"I see. And quinine is good for fever, of course."
"Yes, that's right. Cover a sixpence with the powder, mix it with a little whisky, add a little water, and toss it off."
"And corrosive sublimate?"
"Oh, that's good stuff for washing wounds with, jolly good. Don't make it too strong or you'll burn the bottom out of the pot you mix it in, not to mention the wounded part. About one in ten thousand makes a useful solution if the water you use isn't too dirty."
