^T. 28.] JOURNAL. 215 



went with me to the famous Mineralogical Cabinet, 

 the finest in the world. A most splendid affair it is. 

 It occupies a suite of quite ordinary rooms, but is 

 excellently arranged and shows to great advantage. 

 Here are all the fine gems, diamonds, emeralds, topaz, 

 and all sorts of precious stones, both polished and 

 natiiral. I saw also the bouquet of precious stones 

 made for Maria Theresa, a most brilliant affair. The 

 collection of aerolites is imique. I intend to visit it 

 again on Saturday. I obtained some useful informa-

 " Genera Plantarum," — to look up some reports on 

 education, etc. I asked also for botanical works ; and

 they brought out, as a great rarity, our own " Flora," 

 which I told them I did not want at all. At six 

 o'clock, Endlicher called upon me to take me to the 

 Botanic Garden of the university, under the care of 

 Baron Jacquin, who is professor, at the same time; of 

 both botany and chemistry in the university, and 

 scarcely lectures on either. He introduced me to the
