"I triturated, I infused, I distilled it myself in these very rooms, and know it--know it all--all the ingredients, save one. They are common things enough--comfortable things--some of them a little queer--one or two that folks have a prejudice against--and then there is that one thing that I don't know. It is foolish in me to be dallying with such a mess, which I thought was a piece of quackery, while that strange visitor bade me do it,--and yet, what a strength has come from it! He said it was a rare cordial, and, methinks, it has brightened up my weary life all day, so that Pansie has found me the fitter playmate. And then the dose--it is so absurdly small! I will try it again." He took the silver stopple from the bottle, and with a practised hand, tremulous as it was with age, so that one would have thought it must have shaken the liquor into a perfect shower of misapplied drops, he dropped--I have heard it said--only one single drop into the goblet of water. It fell into it with a dazzling brightness, like a spark of ruby flame, and subtly diffusing itself through the whole body of water, turned it to a rosy hue of great brilliancy. He held it up between his eyes and the light, and seemed to admire and wonder at it. "It is very odd," said he, "that such a pure, bright liquor should have come out of a parcel of weeds that mingled their juices here. The thing is a folly,--it is one of those compositions in which the chemists--the cabalists, perhaps--used to combine what they thought the virtues of many plants, thinking that something would result in the whole, which was not in either of them, and a new efficacy be created. Whereas, it has been the teaching of my experience that one virtue counteracts another, and is the enemy of it. I never believed the former theory, even when that strange madman bade me do it. And what a thick, turbid matter it was, until that last ingredient,--that powder which he put in with his own hand! Had he let me see it, I would first have analyzed it, and discovered its component parts. The man was mad, undoubtedly, and this may have been poison. But its effect is good. Poh! I will taste again, because of this weak, agued, miserable state of mine; though it is a shame in me, a man of decent skill in my way, to believe in a quack's nostrum. But it is a comfortable kind of thing." Meantime, that single drop (for good Dr. Dolliver had immediately put a stopper into the bottle) diffused a sweet odor through the chamber, so that the ordinary fragrances and scents of apothecaries' stuff seemed to be controlled and influenced by it, and its bright potency also dispelled a certain dimness of the antiquated room.
