Institution had changed during that time. < haly Karret remained 

 steadily in his place, untouched by the passing years, the centre 

 and living chronicle of the Kabinett. 



His first paper, on the structure of the Eichkogel near Modling, 

 was published in 1850, in the ' Jahrbuch ' of the Greologische 

 Reichsanstalt. His attraction towards the investigation of the 

 Foraininifera resulted in a long succession of memoirs, which formed 

 his most important contribution to science. In association with 

 Fuchs, he made many excursions to study the geology of the region 

 around Vienna, and the two friends gathered together the results of 

 their researches in a series of ; (Geological Studies in the Tertiary 

 Formations of the Vienna Basin.' which appeared in the ; Jahrbuch" 

 from 1S6S to 1875. The underground water-system of the same 

 region in its geological relations likewise occupied much of his 

 thought, and formed the theme of a number of papers by him. 

 Chief among these is the elaborate monograph which forms the 9th 

 volume of the •' Abhandlungen ' of the Reichsanstalt. published in 

 1877. In this work, which is a study of the Tertiary formations 

 on the western border of the Alpine part of the Vienna Basin, he 

 discusses the geological relations of the various thermal and other 

 springs in that basin, and gives sections illustrative of the structure 

 of the ground traversed by the water-channels, together with 

 copious lists of the organic remains obtained from the strata therein 

 represented. 



Karrer likewise devoted his energies to the development of some 

 departments of industrial geology, particularly in regard to building- 

 materials. He took an active part in the affairs of several Societies, 

 more especially of the Scientific Club, of which he was for many 

 years Secretary. He was enrolled among the Foreign Correspondents 

 of our Society in 1890. Eminently courteous and ever ready to assist 

 others, he was a great favourite with all who knew him. He was 

 twice married. His first wife died without children, but by his 

 second marriage he had a son and two daughters. All through 

 his life he enjoyed remarkably-good health. He was never seriously 

 ill. and at the end of sixtv years he retained the bearing of a vouth. 

 In 1902 he began to suffer from dyspepsia, and an attack of 

 influenza still further afflicted him. In the early spring of last 

 year he was so far better as to be able once more to visit the 

 Museum ; but it was now as an enfeebled old man. He died 

 calmly on the morning of April 19th, 190:S.
