The rainless regions, not deserts, are parts of Guatemala, the table-land

Persia, etc.

The electric character of the air is another subject of interest, and
a leading one in Meteorology. What can be more magnificent, what more
awful, than those storms of lightning and thunder which are witnessed
sometimes even in our own latitudes?

Faraday, who as a chemist and philosophical writer is of the highest
authority, professes to have demonstrated that one single gram of
water contains as much electricity as can be accumulated in eight
hundred thousand Leyden jars, each requiring to charge it thirty turns
of the large machine at the Royal Institution.

It is not intended that this astounding statement should be received
without some grains of allowance; but a very elegant and scientific
writer, who adopts it without hesitation, adds, "We can from this
crystal sphere [of water] evoke heat, light, electricity in enormous
quantities, and beyond these we can see powers or forces for which, in
the poverty of our ideas and our words, we have not names."
