Ixvi PROCEEDINGS OF THE GEOLOGICAL SOCIETY. [April 1914, 



writing a number of papers which dealt with local occurrences 

 and the construction of seismological apparatus. No fewer than 

 130 scientific papers stand to his record, in addition to his official 

 publications. 



Upon his attaining the age of 70, Credner's fellow- geologists 

 showed their high appreciation of his great services to our science 

 by raising the sum of £1000, which they placed in the hands 

 of the Council of the German Geological Society, to be called 

 the Hermann- Credner Fund and to be applied in assisting young 

 geologists in their researches. Geologists in other countries who 

 knew and corresponded with Credner can testify to his geniality 

 and readiness to give help on all occasions. He died, after a long 

 and painful illness, on July 21st, 1913, at the age of 72. [J. W. J.] 



Richard Armin Baltzer was born on January 16th, 1812, and 

 was the son of the pastor of the town of Zwickau in Saxony. The 

 religious struggle of that period shortly afterwards drove his father 

 from Germany, and Baltzer spent his boyhood in Belgium and 

 Switzerland. In 1860 he entered the University at Zurich, where 

 his family settled in 1865. Baltzer studied geology there under 

 Escher von der Linth. In 1864 he removed to Bonn, where he 

 seems to have been mainly engaged in zoological work. His love 

 of mountaineering led him to return to Switzerland, and his first 

 appointment was as assistant in the High School at Zurich to the 

 chemist Wislicenus. In 1868 he became Professor of Geology, 

 Mineralogy, & Chemistry at the Cantonal Technical School in Zurich 

 and also privat-docent at the University and Polytechnic. In 

 1884 he succeeded Bachmann as Professor of Geology & Mineralogy 

 in the University of Berne, and a year later he founded the 

 Mineralogical & Geological Institute of Berne. He retained his 

 Professorship and the Directorship until his death. 



Baltzer was clearly a successful teacher, and he is described bv 

 his colleague Prof. Hugi as a man of exceptionally high character, 

 who strove with all his power to live up to his own conception 

 of his duties. Baltzer was wont to declare that 



' the educational efficiency of a professor depends less on his scientific 

 fame than on his personality, enthusiastic inspiration, and teaching talent. 

 The man and his knowledge must be one, for only thus are they a living 

 influence.' 



He was a man of great physical strength and an able moun- 

 taineer The last years of his life were clouded by great suffering ;
