half or six per cent Of carbonic acid. In
such an atmosphere, life may be kept up
for some time; but respiration is oppros5-
i've and the animal is affected with very
great uncasine3s. Air expired from the
lungs contains about per cent OF fcarbon-
ic acid and hence the atmosphere is n9x-

per cent, and yetwe have seen statements
which affirmed that upwards Of 3 per cont

with importance, in reference to our health,
and to the continued liability We are under
