Post:

I don't think you need a special organ to sense an electric
field. We may not be able to detect the field itself, though I'm not sure
about this, but we have all felt our hair stand up in the presence of
one. When cattle graze, their mouths, which would be much more sensitive
to an electric field or discharge, are near the ground. Do we know what
they might feel under a transmission line? Don't forget, in the study
there were east-west transmission lines, under which the cattle were lined
up east-west. I'm still inclined to think if there is anything to this, it
will be due primarily to electric field effects...
