" Some scientists were of opinion that the rise and fall were the 

 result of wind action, but how can the rise and fall be explained 

 when there is sometimes not a breath of wind? Others were of 

 opinion that the rise and fall might be due to unexpected melting 

 of the snow, and to the action of electric clouds, but if so, why not 

 a like action on all other Italian lakes ? 



" The most probable cause of such uprising, according to the 

 hypothesis of the Engineer Pedrini, is found in the gases which, 

 arising from the bed of the lake and seeking a vent pass across 

 the water, produce undulations, and sudden upward movements of 

 like nature to those observed in the lake of Geneva by Lembari. 

 In the Lago di Garda emanate continuously an infinity of gas 

 bubbles, and thermal springs are observed. 



" The action of the sun upon the Mediterranean raises the water 

 only eighteen inches, and if this attraction on so large a surface 

 is thus weak, the surface of the Lago di Garda is too small 

 comparatively to be at all affected. 



" In the bay of Peschiera, about a hundred steps from Sermione, 

 there are at three different points springs with an unpleasant odour, 

 manifesting the existence of sulphuretted hydrogen gas. Incrustations 

 from thermal waters are to be seen on the eastern side of the lake, 

 about one mile distant from the grotto of Catullus. 



" The fishermen take particular care to extend their nets a distance 

 from these springs ; if they happen to draw the nets over them, 

 they rot in a short time." T. E. Knightley.

EDWARD WALLER CLAYPOLE. 

 BoaN June 1, 1835. Died August 17, 1901. 



Professor E. W. Claypole, one of the many noted geologists 

 of the United States, was of English extraction, having been born 

 at Ross, Hereford, on 1st June, 1835. He was educated privately 

 and graduated at the London University, taking his B.A. in 1862 

 and becoming D.Sc. in 1888. In 1871 be emigrated to the United 

 States, and in 1873 became Professor of Natural Science at Antioch 

 College, Ohio, a post which he held until 1881. He was Palaeon- 

 tologist to the " Second Geological Survey of Pennsylvania " and 

 Professor of Natural Science at Buchtel College, Akron, Ohio, from 

 1883 to 1898, when he succeeded Professor A. J. McCIatchie as 

 Instructor of Biology (to which Geology was afterwards added) 

 at the Throop Institute, Pasadena, California. This office he 

 retained until his sudden death from apoplexy at Long Beach, 

 California, 17th August, 1901. He was a genial and successful 

 teacher, much beloved of his pupils, while his varied attainments 

 find reflection in the scope of his numerous scientific papers, although 

 geology holds the principal place.
