"If!" echoed Lavendale; "that 'if' makes all the difference. If he do not fall off his horse, or if he be not turned over in a stage-coach, or drowned 'twixt Dover and Calais. If he do not fall into a crater, like Empedocles, or if he be not buried in the lava flood, like Pliny, or murdered in the street, like Tom Thynne, or killed in a duel, like Hamilton and Mohun. There is a vast variety of 'ifs' to be considered." Vincenti was not listening to him. He walked to and fro like a man exalted by a beatific vision. Then he suddenly stopped and went over to a furnace, upon which there stood a crucible. He peered into this for some moments, and then resumed his feverish pacings up and down the spacious floor: anon suddenly tottered, and staggered over to his chair, like a man who can scarce keep himself from falling. Lavendale went to him instantly, and put a glass of water to his lips. His brow was damp with cold perspiration, and he had every appearance of fainting. "Is this one of the effects of your panacea," asked Lavendale; "is this the result of that marvel-working Azoth that Paracelsus believed in?" "It is nothing--a passing faintness. The reaction was too strong. I gave myself up too completely to the delight of my discovery--or I may have taken too powerful a dose. I tell you, my lord, the solution is infallible. It contains every element of life, every force that can sustain mind and body, strengthen every nerve, restore the quality of the blood, wasted with age. Feel my pulse, and say if it is not at once regular and strong." "Strong?--yes, too strong for your age; too quick for health. Regular?--no. You had better go to bed, Vincenti. A basin of broth and a good night's rest will do more for you than the higher metals." "Your lordship is mocking me. But I am somewhat exhausted by the unintermittent watching of the last three days and nights. I will lie down for an hour or two, if you will be so kind as to assist me to my room." Lavendale supported him to an adjoining room with almost womanly tenderness, and did not leave him till he was lying comfortably in his bed. He occupied a small apartment next the chapel, a room which had once been used as a sacristy. Here the student of Nature's secret forces had a pallet, and a kind of hermit's cell, preferring such scanty accommodation close to his furnaces and alembics, to the comfortable bedchamber above-stairs which had been allotted to him at his coming.
