OBITUARY. 



GusTAV Rose. — This distinguished mineralogist and chemist 

 died at Berlin, July 15, in the 76th year of his age. In hinu 

 Germany and the world have lost a wise and noble man, — con- 

 ceded by all to be the first in his science among the learned men 

 of Germany. He was the younger brother of Heinrich Rose, the 

 chemist, and the youngest of four sons of Valentin Rose-, who- 

 was Assessor in the " Ober-CoUegium Medicum" of Berlin ; and 

 grandson of Valentin Rose the elder, discoverer of the " Rose'- 

 schen" metals. He early lost his father, and his excellent mother 

 looked after the culture of four sons, whose youth fell upon hard 

 and trying times. All four brothers served their country in the- 

 war for freedom. Gustav, born on the 18th of March, 1798, and 

 17 years old at the date of the battle of Waterloo, did not go inte^ 

 that battle, but made the march under arms from Berlin ta 

 Orleans. 



At first devoting himself to engineering, he fell sick of lung, 

 fever. During his convalesence he gave himself to scientific pur- 

 suits, and this, as well as the influence of his brother Heinrich, 

 led him to leave engineering and devote himself entirely to 

 science. He went to Stockholm where Heinrich was already 

 working under the immortal Bcrzelius. In 1823 he took up his^ 

 residence in Berlin. In 1826, he became " Extraordinary," and 

 in 1839, "Ordinary" Professor of Mineralogy in the University 

 of Berlin, and, after the death of Weiss, Director of the Royal 

 Mineralogical Museum. 



It was the privilege of Gustav Rose to travel extensively, in 

 Scandinavia, England and Scotland, Italy and Sicily, France and 

 Austria. In the year 1829, he made, with Humboldt and Ehren- 

 berg, the famous tour to the Ural and Altai Mountains and the 

 Caspian Sea, and beyond to the borders of China, a journey which 

 first made known the mineralos-ical resources of the extensive 

 Russian Empire. His researches on his native soil were confined 

 to the Silesian Mountains.
