The scientific account of the tremendous volcanic outbreak in the Eastern Archipelago, probably the greatest eruption 

 on record, which destroyed on the spot or by aTesulting tidal wave 36,500 lives, and set up a series of concentric atmo- 

 spheric waves which travelled at least three times round the world. It produced for more than two years, by dust 

 thrown up to an immense height, the most lovely atmospheric effects throughout the world, which were painted for their 

 beauty by an artist at Chelsea, Mr. Ascroft. before anyone had guessed to what cause they were due. 



Included in the volume are: Volcanic Phenomena and the Ejected Materials, by J. W. JUDD, F.R.S. ; Air Waves and 

 Sounds caused by the Eruption, by LT.-GEN. SIR R. STRACHEY ; Seismic Sea Waves, by SIR W. J. L. WHARTON ; Unusual
