ARTIFICIAL FRErzIYC A. A DI,IyfKCT,Nr.-Mr.
L. Merriam, the weather sage of Brooklyn flights. is
somewhere in the interior Of the State, investigating
til merits of machine for producing intense cold by
artificial lie believes that cargoes and vessel,
from yellow fever ports need TO be no longer subjected
to tedious quarantine Of two or three months but that
the cargoos may be discharged and placed in stone
warehouses where by the action of frost, aricialy
produced, all of the yellow fever virus will be des-
troyed. Nesses after unloading. may also be frozen
out 20 that they can with safety come up to the city
and take in new cargoes without DELAY From the well
known fact tina, yellow fever is always imported in
this latitude and disappears however violent before
good frost Mr.. Merriam believes that this city may
be kept free from Infection and the mercantile interests
be also greatly benefited b., the application of artii
cial frost. He gives the following description OF the
refrgcrating machine:
