junction, as a transporting, not an excavating agent, as proved by 

 the soundings at the lower end of the lake. 



Lago Sella and Lago Orsino are shallow tarns which come under 

 the same category as Lago Lucendro. 



Lago d'Elio, draining into the Lago Maggiore, is due to reversal 

 of drainage by a landslip. 



These lakes, then, owe their origin, when they are rock-basins, to 

 the presence of lines of weakness, along which in many cases solution 

 has taken place, while in some shallow tarns ice may have removed 

 detached fragments ; but in no case has a lake been found which 

 can reasonably be assigned to ice-excavation independent of rock- 

 structure. ^

ICE OE WATER. 

 Sir, — Professor Bonney's review of Sir Henry Howorth's new 

 book in your June number just received leaves some of us in a fog. 

 We gather that he thinks the author has seriously damaged some of 

 the positions taken up by the extreme Glacialists, by whom we 

 presume he means Mr. James Geikie and his followers. We gather, 

 on the other hand, that he thiuks Sir Henry Howorth's book an 

 extravagant presentation of the other side, and contrasts Scylla with 

 Charybdis. He apparently feels himself to be in a safe harbour, 

 free from the perils on either side. This does not help us, however, 

 very much. What is now felt to be the important matter, especially 

 by the younger men, is to know where the moderate Glacialist can 

 stand, and as Professor Bonney has himself written a book on the 

 Ice Age, we turned expectantly to his review for some help in this 

 matter, instead of whicli we get some jokes and some generalities, 

 among which we find it difficult to quite understand how the problem 

 now stands, and how far it has been solved or otherwise by the author. 

 I know nothing that would be more welcome to a large number of 

 puzzled young geologists than a frank statement of his own views in 

 your pages by one who bus taught them so much as Professor Bonney. 

 Will he tell us where he thinks they may safely stand, and what 

 limitations he would put on the glacial theory as generally taught 

 by its advocates ? A pkuplexed F.G.S.

As this number is passing for press, we have, with deep regret, to 

 record the sad news of the death of another distinguished geologist 

 and contemporary, Dr. W. T. Blanford, Treasurer, since 1895, of the 

 Geological Society, and a past President (1888-90). He died, after 

 a very brief illness, at his residence, 72, Bedford Gardens, Campdeu 

 Hill, W., 23rd June, 1905, in his 73rd year.'
