which he made himself the acknowledged master. The remark- 

 able and abundant assemblage of cephalopods in the Trias of the 

 Eastern Alps furnished him with an attractive and ample field for 

 the exercise of his singularly acute eye for delicacies of form and 

 structure. His researches among these organisms brought him 

 Triassic material from all quarters for comparison and determina- 

 tion. Thus from the Geological Survey of India he received the 

 large assemblage of cephalopods collected from the Upper Triassic 

 groups of the Himalayas, which he named and described. Prom 

 the Arctic Eegions, from Spain and the Mediterranean basin, from 

 Astrakhan, from Japan, from New Caledonia, and other regions, 

 Triassic cephalopods found their way to him, and enabled him to 

 form those suggestive pictures which he presented of the distri- 

 bution of land and sea and the zoological provinces of Triassic 

 time over the globe. 



Mojsisovics took an active interest in earthquake-research, and 

 for many years was the leading member of the Seismological Com- 

 mission of the Yienna Academy, by which a network of stations 

 was planted over Austria for the purpose of registering earthquake- 

 disturbances. He was a frequent attendant at the meetings of the 

 International Geological Congress, where he was welcomed by 

 geologists from all regions of the globe, and where his assistance 

 was always readily given towards the preparation of the great 

 International Geological Map of Europe. His helpfulness to 

 science will long outlive him, for he has by his will left to the 

 Vienna Academy the greater part of his estate of more than a 

 million of crowns, to be applied, after the decease of his widow, for 

 the furtherance of scientific studies. ^ 



Dr. JoHANN Ekiedeich Cael Klein had for the last forty years 

 been an accomplished and constant contributor to the literature of 

 descriptive mineralogy. He had also studied the crystallography 

 of various artificial compounds. His * Mineralogische Mittheilungen ' 

 have long been a conspicuous feature in the ' jN'eues Jahrbuch.' His 

 eminence in his own subject was recognized by his being appointed 

 Professor of Mineralogy in the University of Berlin, and by his being

 to two necrologies of him — one by Prof. Diener of the Vienna University 

 ('Beitrage zur Palaontologie & Geologic Osterreicb-Ungarns & des Orients '

 Eeichsanstalt (Verhandl. Geol. Reicbsanst. 1907, No. 14).
