In 1855 he explored the littleknown valleys between Monte Rosa and Mont Blanc ; and subsequently published ' The Italian Valleys of the Pennine Alps,' a work that is of very high value, from the rare combination of literary ability with great powers of observation and artistic skill which it manifests.
