She has herself requested me to keep it under lock and key, so long as it is wanted in this house." He opened an old cabinet, and took out a long narrow bottle of dark-blue glass.

In form, it was quaintly and remarkably unlike any modern bottle that I had ever seen.

The glass stopper was carefully secured by a piece of leather, for the better preservation, I suppose, of the liquid inside.
Down one side of the bottle ran a narrow strip of paper, notched at regular intervals to indicate the dose that was to be given.

No label appeared on it; but, examining the surface of the glass carefully, I found certain faintly-marked stains, which suggested that the label might have been removed, and that some traces of the paste or gum by which it had been secured had not been completely washed away.
