peculiar to chemists, Pembury watched him impassively.
"I suppose you don't keep musk?" he asked carelessly.
The chemist paused in the act of heating a stick of sealing-wax, and appeared as if about to mutter an incantation. But he merely replied: "No, sir. Not the solid musk; it's so very costly. But I have the essence."
"That isn't as strong as the pure stuff, I suppose?"
"No," replied the chemist, with a cryptic smile, "not so strong, but strong enough. These animal perfumes are so very penetrating, you know; and so lasting. Why, I venture to say that if you were to sprinkle a table-spoonful of the essence in the middle of St. Paul's, the place would smell of it six months hence."
"You don't say so!" said Pembury. "Well, that ought to be enough for anybody. I'll take a small quantity, please, and, for goodness' sake, see that there isn't any on the outside of the bottle. The stuff isn't for myself, and I don't want to go about smelling like a civet cat."
"Naturally you don't, sir," agreed the chemist. He then produced an ounce bottle, a small glass funnel and a stoppered bottle labelled "Ess. Moschi," with which he proceeded to perform a few trifling feats of legerdemain.
