Finland

Finland, GULF OF, the eastern arm of the Baltic Sea, between 22° and 30° E. long., and between 59° and 61° N. lat. It receives the waters of the great lakes Onega and Ladoga. The water of the gulf is not deep, and only very slightly salt. The topography of the Gulf of Finland, which has been thoroughly elucidated by Struve, forms an interesting part of the great work of the Russian survey of the Baltic. The navigation on the northern or Finnish coast is very dangerous, on account of the numerous islands and shoals.
