Sir Frederick Mohs. 258 



Mohs, by his lectures, had attracted many students from the 

 Imperial States to Gratz. Count Brunner, Hereditary Cham- 

 berlain of Austria, was among the number. He engaged in the 

 subject with peculiar enthusiasm, and invited the Professor to 

 accompany him in a tour through England and France, a pro- 

 posal which met with the concurrence of the Archduke John 

 and the State of Stiria. The travellers arrived in London in 

 the beginning of January 1818, went to Cornwall, and then 

 from London to Edinburgh. Here Mohs found his friend 

 Professor Jameson occupied with views similar to his own re- 

 garding the natural history of the mineral kingdom. They 

 soon agreed as to the principal points ; and Mr Jameson, who 

 was then engaged in revising the third edition of his " System 

 of Mineralogy," adopted part of the views of Professor Mohs. 



Mohs fii-st published his " Characteristick "' in German and 

 English merely as a fragment. In the following year appeared 

 " Jameson's Manual of Mineralogy," in which the author 

 adopted the natural method, with but iew alterations in the no- 

 menclature, and thus introduced it into England. 



Mohs, upon his return to Edinburgh from an excursion to 

 the Highland.s, found an invitation to the chair of his immortal 

 instructor Werner, which he accepted, provided the consent of 

 the Archduke John could be obtained. This he received in 

 a letter written by the Archduke himself, from Dresden, and 

 he entered into his professorship in the autumn of 1818. The 

 above mentioned " Characteristick," which was published in 

 1820, passed through a second edition in the following year, 

 accompanied with an explanatory introduction. In 1822, Mohs 

 published the first part, and in 1824, the second part, of his 

 Elements of Mineralogy, the most remarkable work on minera- 

 logy which has appeared in our time. Three or four years ago, 

 Mohs was invited by the Emperor of Austria to Vienna. He 

 accepted the offer of Professor of Mineralogy there, and has 

 been succeeded in Freyberg by Nauman, the celebrated mi- 

 neralogist, from Halle.
