I closed the day with the English Opera. At the end of the first act a mine falls in and buries the principal persons of the piece alive. In the last scene of the second act they reappear in the bowels of the earth, nearly starved indeed, having lain there three days, and utterly exhausted. This, however, proves no impediment to the prima donna singing a long Polonaise air, to which there is a chorus with trumpets, "Ah, we are lost, all hope is gone!" but, oh miracle! the rocks fall asunder again, and open a wide entrance to the light of day. All distress, and with it the distressing nonsense of the piece, was at an end. _August 2nd._ Yesterday's debauch called my attention to an organ which Mr. Deville did not include in his list--the organ of 'gourmandise,' which immediately confines on that of murder, and is in fact, like that, a species of destructiveness. I find I possess it in a considerable degree, and I only wish all the bumps and knobs on my skull gave as innocent and agreeable results. It indicates not the mere vulgar desire for eating and drinking, but enables its possessor to estimate the delicate fragrance of wine, or the inventive genius of a cook. It is inimical to human happiness only when found in conjunction with a sentimental stomach,--which happily does not appear to be the case with me. To-day I saw an exhibition of an entire gallery of pictures embroidered with the needle, and the work of one person: their excellence is really surprising. The name of the artist, the most patient of women, is Miss Linwood. At a little distance the copies are very like the originals, and the enormous prices she gets for them shows that their merit is recognized. I heard that one such piece of tapestry, after Carlo Dolce, sold for three thousand guineas. There was a portrait of Napoleon during the Consulate, which must have been very like him at that time, and was regarded by some Frenchmen present with great admiration. I next went to see the solar microscope, the magnifying power of which is a million. What it shows is really enough to drive a man of lively imagination mad. Nothing can be more horrible,--no more frightful devilish figures could possibly be invented,--than the hideous, disgusting water animalculæ (invisible to the naked eye, or even to glasses of inferior power,) which we daily swallow. They looked like damned souls darting about their filthy pools with the rapidity of lightning, while every motion and gesture seemed to bespeak deadly hate, horrid torture, warfare, and death. I was seized with a sight-seeing fit, and wished to efface the shocking impressions of that infernal world by something more agreeable. I visited three panoramas,--Rio Janeiro, Madrid, and Geneva.
