EDWARD F. RIMBAULT.

_Serius, where situated?_ (Vol. iii., p. 494.).--The Serius, now Serio,

rises in the chain of mountains in the south of the Valteline, between

the lakes Como and Ixo: it flows through a valley called the Val Seria,

passes near Bergamo and Cremona, and falls into the Adda a little before

that river joins the Po.
