There were many people engaged, like myself, in examining these bottles; and amongst them I found a pretty woman of my acquaintance, who had once been remarkable for vivacity, but had suddenly fallen into a pensive dejection, for which she could give no reason, except that assigned in Shakspeare,--that she was sad because she was not merry. Feeling severely the want of her former mirth, she had travelled to the moon in quest of it, where, being directed to this building, she had discovered the bottle containing her own spirits, and I found her considering by what expedient she could transfer them to herself. She had intended to carry away the bottle, and meditate some contrivance at her leisure; but they were all fixed immoveably in the shelves, so that whatever plan should be tried it could only be practised on the spot. She consulted me in her difficulty; and remembering the invention described by Ariosto, I advised her, when the cork should be removed, to hold her head over the bottle, and endeavour to inhale the vapour which should issue forth. She stood ready, and I cut the string which confined the cork; when it instantly flew out with a loud report, and a roar of laughter rushed after it: this was the imprisoned merriment escaping, and it lasted as long as the vapour continued to come forth. The lady applied herself to it as if to a smelling-bottle as long as this violent evaporation lasted. When the bottle had ceased to laugh she raised her head, and I immediately saw that my invention had succeeded; her eyes had regained their mirth, and her mouth its beautiful smile. She walked away in great delight at finding herself happy again. There were many other people in the room who, having found the bottles belonging to themselves, were in perplexity about the means of recovering the contents; and now, having observed the success of my contrivance, they began to practise it upon themselves, so that very soon I heard corks flying and bottles laughing on every side. The first restoration of lost mirth had a violent effect upon most of the patients, and raising their heads at the end of the operation they burst into a vehement fit of laughter; some danced about very zealously, and performed other exploits. But this frantic delight sunk gradually, and in a few minutes was turned into a steady and reasonable cheerfulness. The first senseless joy from these bottles very much resembled the wild behaviour from nitrous oxide, popularly called laughing gas, which he who inhales commonly has recourse to a violent career of laughter, without being able to assign any just grounds of merriment. Those who have seen this common experiment, may conceive exactly the extravagances acted in consequence of these bottles.
