AND CURE OF SEASICKNESS.

"the majority Of deaf mutcs are M.
immune to seasickness."
Another error Is due to common
Misunderstanding OF the true natp,.
Of vertigo. Many physicians seem IA
take 1t for granted that the d.zzlnes.
produced when a man is reyolvsS
rapidly In a chair Is the same as ,bo
vertigo OF seasickness. 1t is argued
that in both cases there is yio,sn,
oscillation Of the fluid in the semi.
circular canals, and that the yer,iso
and sickness produced must have tho
same origin. Recently the cause in
both cases has be n sought mora
deeply, and 1t is found that in tina
purely artificial vertigo OF the "a.
volving chair there is also oscillatlo,
OF the eyeball, different position n,
the head. and n form OF dizzine,,
which leads a man to stumble for.
ward. In seasickness all these symn.
toms are absent
The cause Of sea vertigo is therefor.

canals may or may not be disturbed.
In searching for the true cause ~

In other words. the aim Of his IN.
vestigations was to find the factor
which is responsible for the ailment
In all cases. Such a survey has not
been hitherto accorded to seasickness
The starting point was the fact noted
by all physicians that children sci.
dom suffer, while infants are nearly
immune. 1t is also a fact that SOM.
children are unable to use a swing
to do rope dancing, or travel on A
chute or switchback railway owing ia
nausea, giddiness and headache being
caused. Adults suffer in the sans
way when a ship falls into the trough
OF the sea, when an elevator drop,
suddenly, or when a swing or a ham.

This theory explains the immediate

glands are stable, not being much az
fected by nervous impressions, while
their small bodies and firm muscles
give little grasp for the oscillations
OF the sea. This explains why adults
are benefited by wearing belt

which acts instantly II taken before
meals. and is equally eficaclous in
seasickness and in the sickness ex.
perienced on railway trains.
In detailed account OF the remedy
the French physician explains its &C.
ton. In ordinary language adrenans
Is the product of the suprarenal glands,
and in its pure chemical form is
well-known stimulant. In seas!ckness
there is n deficiency Of this substance
In the blood, and the result is loss o,
control over the stomach and nerves
which are specially affected by the mo-
ton of vessel at sea. Contro and
equilibrium are speedily restored when
adrenaline is taken, and the symptoms
OF seasickness soon disappear An.
parently the body is stabilized by this
agent. This remedy is also much used
at the front in checking bleeding, and
Is an approved war measure. on ac-
count of the authoritative source Of
this discovery 1t is given more
credence than cures for seasickness
have usually obtained. B.
