Hearing and Nervous and Vascular
Systems Perfectly Sound.
Those who are up into the air in fy.
ing machines as well as those who go
down to the sea in ships are troubled
by peculiar and unpleasant physiolog
ical disturbances which may at times
be of grave moment This is especial
ly true of aeroplane pilots >or passen
gers and to less degree of those who
ascend in balloons or dirigibles. The
tremendous Importance of aviation in
war lends this subject peculiar inter
est, and LarousSe MenSuel Paris) de
votes a special article to the topic. The
author. DR.. Laumonier, states that the
symptoms vary according to the period
Of ascent. of descent and of landing.
In ascending an acceleratiOn of the
respiration and pulse are frequently
noted at from 1900 to 1900 meters al
titude, accompanied by a slight head
ache located in forehead and temples
and by indetinable discomfort without

there is a diminution in the ~kcenness
of hearing; at times there are halluci
nations and finally an "asthenic" con

On descending the palpitations of
the heart become violent and are ac-
%conlpanied by a sensation of anguish,
the headache is intense, the aviator
has an Increasing sensation of heat of
the skin. especially OF the face, and a
desire to sleep. which is sometimes SO
strong that the eyes Involuntary close
as he approaches the earth. in spite of
imminent peril.
Strange to say, on landing these trou,
bles are augmented. Besides the head
ache and the somnolence. hyperemia of

ties. acceleration of the pulse and con
slant increase of a~rterial pressure. The
aviator often falls asleep as soon as he
lands. and this sleep is troubled and
nonrefreshing. While the headache may
persist for many hours or even several
days.
The ascent symptoms recall those of
mountain Sickness but are produced
at a less altitude, because of the nerv-
Gus tension. the cold and above all the
relative rapldlty or ascension. but
what distinguishes aviators' sickness
from mountain sickness IS that the
symptoms persist during descent ana
are aggravated AFTER landlng. iheFe
