Whether the latest remedy. or rather pre-

well says 1t Is. He asserts that the rea-
son to little attention has been paid to
seasickness, especially by those not sub

idea that to be seasick did a person good;
that 1t cleared out the system, and there,

course: DR.. Rockwell holds that there

tie of prevention must be fought on land
before sailing. For three days before the
voyage doses Of bromide OF sodium must
be taken-in preference to bromide of
potassium-and this course must be con-
tinued for three or four days after sail
ing. One pleasant effect of this bromza-
tion is the sound and refreshing nature
of the sleep 1t induces. The dose recOm-
mended by DIR. Rockwell Is thirty grains
OF bromide OF sodium three times day
for three days before the voyage. and for
three or four days after starting. He has

Among the novelties In bicycle gear is a
new foot clip, which has several good
features. The construction is such that
when the pedal Is not in use and hanging
downward, the tOe-clip swings out of the
way, so that the pedal may be caught by
the riders foot without any attention bee
Is placed upon the pedal the clip flies into
position where II locks firmly. When the
foot is removed. and the pedal turns with
the clip on the underside, the mechanism
Is ready for further use. BY the use Of
this clip the safeguards on the pedals may
be dispensed with. as the clip Is prOvid-
ed with q metal strip, which acts as a
or wider to suit the riders foot The clip
weighs three ounces. 1t Is simply and
strongly made, and can be adjusted to fit
almost any kind of pedal. The inventor

appliance. which can also be used as n
