The Section OF General Physics met IN the
Chemical Hall Of the University, with Prof. HENRY
as Chairman, and Prot -ILLIMAN Secretary.
Aier the necessary prelmnarcs. the hrst paper read
was Report on Winds the Laws % AtmOsph ~
Circulation in the Northern Hemisphere, by Prot
COFFIN This paper related TO tue direction oil the
10 wer strata Of the air whole as they move over
different regions Of the Northern Hemisp herei and
treated the laws Of any which the winds observe In
their variations from their general course. BY the
term l0up strata Prof C. included al those within tne
reach of observation whether by the motions OF the
clouds or by means Of for they al belong 20
