"And is it in the hope of that notable discovery you have studied chemistry, electricity, and magnetism? Again I say, Silly boy!" Margrave did not heed my reply. His face was overcast, gloomy, troubled. "That the vital principle is a gas," said he, abruptly, "I am fully convinced. Can that gas be the one which combines caloric with oxygen?" "Phosoxygen? Sir Humphrey Davy demonstrates that gas not to be, as Lavoisier supposed, caloric, but light, combined with oxygen; and he suggests, not indeed that it is the vital principle itself, but the pabulum of life to organic beings." [1] "Does he?" said Margrave, his, face clearing up. "Possibly, possibly, then, here we approach the great secret of secrets. Look you, Allen Fenwick: I promise to secure to you unfailing security from all the jealous fears that now torture your heart; if you care for that fame which to me is not worth the scent of a flower, the balm of a breeze, I will impart to you a knowledge which, in the hands of ambition, would dwarf into commonplace the boasted wonders of recognized science. I will do all this, if, in return, but for one month you will give yourself up to my guidance in whatever experiments I ask, no matter how wild they may seem to you." "My dear Margrave, I reject your bribes as I would reject the moon and the stars which a child might offer to me in exchange for a toy; but I may give the child its toy for nothing, and I may test your experiments for nothing some day when I have leisure." I did not hear Margrave's answer, for at that moment my servant entered with letters. Lilian's hand! Tremblingly, breathlessly, I broke the seal. Such a loving, bright, happy letter; so sweet in its gentle chiding of my wrongful fears! It was implied rather than said that Ashleigh Sumner had proposed and been refused. He had now left the house. Lilian and her mother were coming back; in a few days we should meet. In this letter were inclosed a few lines from Mrs. Ashleigh. She was more explicit about my rival than Lilian had been. If no allusion to his attentions had been made to me before, it was from a delicate consideration for myself. Mrs. Ashleigh said that "the young man had heard from L---- of our engagement, and--disbelieved it;" but, as Mrs. Poyntz had so shrewdly predicted, hurried at once to the avowal of his own attachment, and the offer of his own hand. On Lilian's refusal his pride had been deeply mortified. He had gone away manifestly in more anger than sorrow.
