Paris Nov. 23-Great interest has been
aroused here by the balloon experiments ior
the study OF the physiological conditions OF man
at high attitudes, made under the auspices oi
the Academy of Medicine. These are under the
direction Of Professor Chauveau. or the Acaoe
NV of Sciences. who for twelve years has been
at work founding laboratory Tor the INV es'i-

DR.. PORTER, when asked about his ascension,
said: THE experiments show that a cubic
