It is one of the misfortunes of meterology, that authors with little knowledge of the related sciences are among its chief leaders. Just now a translation of a work by Professor Schouw, called "Earth, Plants and Man," is exciting attention in Europe.

It is a similar work to that of Marsh's "Man in Nature." According to the English translator, Schouw teaches that "Tracts destitute of woods become very strongly heated, the air above them ascends perpendicularly, and thus prevents the clouds from sinking;" and in this great principle we have a learned essay on what governments ought to do in the way of Forestry, and so on.

In this part of the world heated air always ascends perpendicularly whether it rises from tracts destitute of wood or otherwise; but the "preventing the clouds from sinking" is very funny when it is known to every gardener who has watched hot water circulate, that the hot "current" cannot rise without the cold current sinking and taking the place of the warmer by the return pipes to the boiler. Currents in the atmosphere are under precisely the same laws as currents in hot water pipes, and it is as sensible to talk of hot water preventing the cold water from sinking, as to say that warm air currents hold up the cold clouds above them. It is not to be wondered at that with such a dim perception of natural law the whole of the Professor's book amounts to little more than nonsense.
