1862, and he had much difficulty in completing his course of lectures. In 

 the autumn of this year he went again to the Rhine, but only to stay in a 

 country-house near Bonn, the home of his son-in-law. Professor Busch. 

 Here his health appeared to revive, and he returned to Berlin feeling so 

 much better that he commenced his winter lectures ; a fortnight before 

 Christmas, however, he was obliged to give them up, never again to be 

 resumed. In the spring of 1863 he retired to a country-house at 

 Schoneberg, near Berlin, and here, on the morning of the 28th of August, 

 his valuable life was closed by a painless death. His name will ever be 

 cherished in the annals of that science which he had so greatly enriched. 

 Few philosophers have ever united such a versatility of genius with a mind 

 so severely disciplined, or who, possessing such a talent for observing, were 

 able to deduce such important results from their observations. 



He was member of probably every xlcademy in Europe. He was elected 

 Foreign Member of the Royal Society in 1828; the Royal Medal was 

 awarded to him in 1829, "for his Discoveries relating to the Laws of 

 Crystallization, and the Properties of Crystals." 



In 1852 he was elected Foreign Associate of the French Institute, in the 

 place of (Ersted.

Carl Ludwig Christian Rumker was born on the 28th of May 1/88, 

 at Neubrandenburg in IMecklenburg-Strelitz, in the service of which State his 

 father held an important position. After a careful preparatory education 

 at home, he was sent to the Graue Kloster at Berlin, and later to the 

 Engineering Academy of that place. In 1807 he passed the Government 

 examination for qualification as an engineer and architect. 



In consequence of the gloomy aspect of affairs in Prussia after the peace 

 of Tilsit, he endeavoured to establish himself in Hamburg ; but here also, 

 finding no prospect of occupation in the profession he had adopted, he 

 resolved in 1808 to go to England with the intention of devoting himself 

 to a seafaring life. Accordingly, in the 21st year of his age, he began the 

 world anew, under the most unfavourable circumstances, in a strange coun- 

 try, without friends, and entirely cut off from his home by the continental 

 blockade. Witb an energy and strength of character peculiarly his own, he 

 overcame the difficulties of his situation, and obtained an appointment as 

 Midshipman in the Navy of the East India Company. Feeling dissatisfied 

 with this service, he entered into that of the German house of Rlicken in 

 London, and visited many parts of the world in their ships. In 1811 or 

 1812 he obtained admission into the Royal Navy, and served during the 

 latter part of the war on board various ships of the Mediterranean fleet. 

 He was first appointed to the * Benbow ' ; afterwards he became Naval In- 

 structor on board the * Montague,' Captain Peter Hey wood (formerly of the
