 note = {Wiggle-motion of a fish causes an opening to be made between the scales in the direction of
body-breadth.
Irrespective of the small breadth of the opening, if the scale-rising on the body-surface is slow
on the convex-side of the wiggle, returning quickly to the former state on the concave-side of it,
the occurrence of thrusting is assumed.
This thrusting is supposed to decrease the swimming-resistance of fish in cooperation with
the effect of the progressive-wave of the scale plates, running from forward to backward.
In order to ascertain this, a two-dimensional large-fish-scale model was made, and the following were investigated by experiments,
existence of thrusting-occurrence, the scope and
variations, e.t.c..
The results are as follows：－
(1) It was observed that the production of thrusting which is followed by a running of
current, is to be brought forth by the movement of scale plates which are opening slowly
and closing quickly.
It was confirmed that the shorter is the period of the movement, the faster is the
current running along the scale plates; the maximum speed of the current being 14.5 cm
/sec, the maximum of the dynamical pressure of the current being 7199.2 dyn/cm^<2> (7.3 gr.wt/cm^<2>).
(2) The water in the water-way began to circulate about 3 minutes after it started to move
the scale plates, and about 10 minutes had passed before the current was settled.},
