ulus, as related by Livy, and goes on with other accounts of sub-

A supplemental chapter contains a notice ‘of meteoric dust 
showers since 1846. One on the 31st of March, 1847, in the 
valley of Gastein, in Salzburg ; another in Arabia, Jan. 24, 1848 ; 
another in Silesia and Lower Austria, Jan. 31, 1848, The show- 
ers afforded similar fresh-water and ‘continental forms, with the 
same South American species before mentioned, and no char- 
acteristic African form. Other showers occurred in 1849. In 
March there was a reddish dust fell at Catania in Sicily, during 
a south wind. On the 14th April, during a hail storm in Ireland, 
there was a black inky deposit, affording numerous microscopic 
organisms.
