| contents | The Humaljärvi lake is situated 25 km West of Helsinki (formely, Helingsfors). The author proceeded to dredge the bottom of the lake in order to study its plancton species following a preceeding study of Pr. J. E. Rosberg in 1900. From the middle of the lake, at a maximum depth of about 10 meters the dredge brought easily some fairly soft gray mud. When the mud samples were sifted, it remained sand grains and ferro-manganese deposits in the form of abundant small round or lenticular objects, 2-6 mm in diameter. |
