Now for the Jardin des Plantes and its lectures. This same Jardin is a large space appropriated to Botanical pursuits, public walks, menageries, museums, &c. There you see Bears and Lions and, in fact, the finest collection of Birds and Beasts alive, some in little paddocks, others in clean and airy dens. But this is the least part of this delightful establishment; its museums and cabinets are like the Louvre, the finest collection in the world. Everything is arranged in such order that it is almost impossible to see it without feeling a love of science; here the mineralogist, geologist, naturalist, entomologist may each pursue his favourite studies unmolested. Here, as everywhere else, the utmost liberality is shewn to all, but to Englishmen particularly, your country is your passport. Like the mysterious "Open Sesame" in the Arabian nights, you have only to say, "Je suis Anglais" and you go in and out at pleasure. I have seen Frenchmen begging in vain with ladies and officers of the party and turned away because they had happened on the wrong day or hour, and then we, without solicitation, have been desired to walk in. But all these museums and living animals, curious and interesting as they are, are surpassed by the still greater liberality shewn in the daily lectures given by the members of the Institute or Professors of the several sciences. I have attended Haiiy,[47] Duméril,[48] l'Ettorel, du Mare, and others upon Mineralogy, Nat. Hist., and Entomology, and Haiiy, you know, is the first mineralogist in Europe, and I never looked upon a more interesting being. When he entered the lecture room, every one rose out of respect, and well they might. He is 80 years of age apparently, with a most heavenly patriarchal countenance and silver hair; his teeth are gone, so that I could not understand a word he said, though, indeed, had he been possessed of all the teeth in Christendom I apprehend I should not have been much wiser, as he lectured on the angular forms of the Amphiboles. He looked like a man picked out of a crystal, and when he dies he ought to be reincarnated and placed in his own museum.
