dinal section C D, that the rain falling on the country between H and 

 K will percolate through the soil and fissures of the rocks until it 

 meets an impervious bed, along which it will run, and issue at the 

 outcrop as a spring, as shown in the cut. This bed being cut through by 

 the rail way- works, the water was intercepted and carried into the 

 tunnel, drying up the spring ; a prediction that was verified by the fact. 

 I have been informed that the pumping of the water alone, out of the 

 tunnel, during the construction of the works, cost the contractor nearly 

 as much as all the other works relating thereto put together. 



ABSTRACT FROM MM. VON HATTER'S AND HORNES' REPORT 



CONCERNING THE ERECTION OE THE MONUMENTAL 



ELOCK IN COMMEMORATION OF LEOPOLD YON BUCH. 



Communicated by Count Maeshall, of Yienna. 



It will be remembered that, on the motion made by M. E. Ehrlich, 

 Keeper of the Provincial Museum at Linz (September 20th, 1856), the 

 section for Mineralogy, Geology, and Palaeontology of the Congress of 

 German Naturalists and Physicians, then meeting at Yienna, resolved 

 by unanimous acclamation, that an erratic block of granite, situated 

 near Losenstein, between Steyer and Weyen (upper Austria) should be 

 converted into a monument commemorative of the illustrious geologist, 

 Leopold von Buch. In consequence of this resolution, MM. von Hauer 

 and Homes formed, with M. Ehrlich, an executive committee, opened 

 a subscription with a maximum amount of five florins (about ten 

 shillings) and took every measure to ensure the success of the enter- 

 prise by enlisting contributions at home and abroad. The success 

 proved to be beyond expectation. H.S.H. Archduke Stephan and the 

 illustrious Baron de Humboldt expressed their assent in the most 

 flattering terms ; Baron Scheucheustael, at the head of the mining 

 department in Austria, and Baron Beust, occupying the same official 

 station in the kingdom of Saxony, have been most active in promoting 

 the subscription within their spheres. 



As soon as Sir Roderick I. Murchison had received notice of the 

 project by a letter from Director Haidinger, he answered that, if the 

 amount of the subscription should prove insufficient for the intended 

 monument, he himself was ready to fill up the deficit from his own 

 funds. The French Geological Society proved not less active in pro-
