Fo-Hi having added some bright green fluid to that in the flat pan, had now poured the whole into a large test-tube, and was holding it in the flame of the burner. At the moment that it reached the boiling point it became colourless. He carefully placed the whole of the liquid in a retort to which he attached a condensor. He stood up.
Crossing to a glass case which rested upon a table near the diwan he struck it lightly with his hand. The case contained sand and fragments of rock, but as Fo-Hi struck it, out from beneath the pieces of rock darted black active creatures.
"The common black scorpion of Southern India," he said softly. "Its venom is the basis of the priceless formula, F. Katalepsis, upon which the structure of our Sublime Order rests, Dr. Stuart; hence the adoption of a scorpion as our device."
He took up a long slender flask.
"This virus prepared from a glandular secretion of the Chinese swamp-adder is also beyond price. Again-the case upon the pedestal yonder contains five perfect bulbs, three already in flower, as you observe, of an orchid discovered by our chief chemist in certain forests of Burma. It only occurs at extremely rare intervals—eighty years or more—and under highly special conditions. If the other two bulbs flower, I shall be enabled to obtain from the blooms a minimum quantity of an essential oil for which the nations of the earth, if they knew its properties, would gladly empty their treasuries. This case must at all costs accompany me."
"Yet because you are still in England," said Stuart huskily, "I venture to hope that your devil dreams may end on the scaffold."
"That can never be, Dr. Stuart," returned Fo-Hi placidly. "The scaffold is not for such as I. Moreover, it is a crude and barbaric institution which I deplore. Do you see that somewhat peculiarly constructed chair, yonder? It is an adaptation, by a brilliant young chemist of Canton, of Ericksen's Disintegrating Ray. A bell hangs beside it. If you were seated in that chair and I desire to dismiss you, it would merely be necessary fro me to strike the bell once with the hammer. Before the vibration of the note had become inaudible you would be seeking your ancestors among the shades. It is the throne of the gods. Such a death is poetic."
He returned to the table and, observing meticulous care, emptied the few drops of colourless liquid from the condenser into a test-tube. Holding the tube near a lamp, he examined the contents, then poured the liquid into the curious yellow bottle. A faint vapour arose from it.
"You would scarcely suppose," he said, "that yonder window opens upon an ivy-grown balcony commanding an excellent view of that picturesque Tudor survival, Hampton Court? I apprehend, however, that the researches of your late friend, M. Gaston Max, may ere long lead Scotland Yard to my doors, although there has been nothing in the outward seeming of this house, in the circumstances of my tenancy, or in my behaviour since I have—secretly—resided here, to excite local suspicion."
"Scotland Yard men may surround the house now!" said Stuart viciously.
