The most highly heterogeneous barleys,
l.. Marx finds, are those of Russia and
Baden /; then follow those Of Sweden,
North Germany, Alsace, Hungary and
France. English and Austrian barleys
come lowest, with respective means Of

maintained that while the atmosphere
is the main, IL not the exclusive, source
of carbon for crops the soil is the prin.

arabic soil loses az much nitrogen in

static electricity, may be explained
either az an effect of electrodynamic in.
duction or as an effect of electrostatic
induction.
