They retired to the baroness’ bedroom, and in ten minutes the baroness came forth in a neat gingham gown. Over this she wore an apron of the same material, but of darker pattern, that covered her completely.
Florine knew just what to do for the experiments her employer was about to make.
From two large trunks which stood in her own room she took a small electric stove, crucibles, retorts, and similar articles. Also a glass table, which folded when packed away, but could be set up quite firmly in a few minutes. It was the kind of table that is often used by experimenting chemists.
“That will do,� the baroness told her then. “You can stay out here, in my sitting room. Remember that no one is to be allowed to come in until I tell you.�
She shut herself in the bathroom, the ground-glass window of which was open a little at the top, and placed a crucible, containing some colorless liquid, on the electric stove.
She had connected the stove by wires to one of the electric fixtures, after removing the bulb, and thus got all the power she required.
Soon there came a slight hissing from the crucible.
She darted over to it, and having put on a pair of asbestos gloves, lifted the crucible to the glass table.
Next, she adjusted an oxygen mask with a glass front, and, taking off the asbestos gloves, replaced them with others of rubber. She knew well the necessity of taking every precaution when experimenting with dangerous elements.
Taking a small bottle from a cabinet, which had been one of the articles brought in by Florine, she poured half of the liquid in it into the crucible.
