students from many countries, who were attracted no less by his 

 personal qualities than by his genius and encyclopaedic knowledge. 

 Many of the leading petrographers of the present day have been 

 eager disciples of Rosenbusch, as may be seen in the ' Festschrift ' 

 by which his old students celebrated his seventieth birthday. 



His specific contributions to petrography and the chemistry of 

 rocks were numerous and valuable, and he was also from 1888 to 

 1907 Director of the Geological Survey of Baden ; but his memory 

 will be associated chiefly with his teaching at Heidelberg and with 

 his monumental work, the ' Mikroskopische Physiographic. ' This 

 has passed through four editions ; and it is remarkable, alike for 

 the comprehensive knowledge of the subject which it testifies, and 

 for the critical acumen shown in handling so multifarious a body 

 of material. 



He was the recipient of numerous honours, at home and abroad. 

 He Was elected a Foreign Correspondent of this Society in 1886, 

 and a Foreign Member in 1890. In 1903 the Wollaston Medal 

 was awarded to him. Excepting a memorable excursion to Norway 

 in 1888, his geological travels belong mostly to the years before 

 1878. During his Professorship, and after his retirement, he was 

 to be found usually at Heidelberg, where he lived in a villa named 

 after his native town. He had married in 1869 Fraiilein Auguste 

 Miiller, also of Einbeck. His wife survives him, but their only 

 son died in childhood, a loss which was deeply felt. After enjoying 

 good health to an advanced age, Geheimrath Rosenbusch died, after 

 a short but painful illness, on Januarv 20th, 1914, in his 78th year. 1

Prof. Antox Fritsch, who became a Foreign Correspondent of 

 the Society in 1888 and a Foreign Member in 1897, was born at 

 Prague in 1832, and spent all his life in that city. He was 

 appointed assistant in the Zoological Department of the Royal 

 Bohemian Museum in 1852, and eventually attained the director- 

 ship of the Natural History Departments of the Museum, which he 

 still held at the time of his death. For many years he was also 

 Professor of Zoology in the Royal Bohemian University, and the 

 responsible head of the Natural History and Geological Survey 

 of the Kingdom of Bohemia. His earlv researches were almost 

 entirely zoological, but association with Barrande appears to have
