curve No. 240, Eig. 101, is constructed from a serial
sounding in a cold current which passes into the
North Pacific from the Sea of Okotsk, prohahly
through Pico or Bonssole Channel. This may be
only a summer current, and due in a great measure
to the melting of the snow over the enormous drainage
area of the Amur and the southern Siberian
rivers. Curves No. 80 and A. and B. in Pig. 100 are
introduced to show what we are inclined to regard as
the underlap of the water of the equatorial reflux,
steadily cooling but still abnormally warm, against
the coast of Europe. The following tables give the
positions of the serial soundings :—
