THE GERMAN NATIONAL MONUMENT.--WAR AND PEACE.
A writer in the London Lancet ridicules a
habit of being in great haste and terribly pressed for time which is
common among all classes of commercial men, and argues that in most
cases there is not the least cause for it, and that it is done to convey
a notion of the tremendous volume of business which almost overwhelms
the house. The writer further says that, when developed into a confirmed
habit, it is fertile in provoking nervous maladies.

The belief that population in the West Indies is stationary is
so far from accurate that, as Sir Anthony Musgrave points out, it
is increasing more rapidly than the population of the United
Kingdom. The statistics of population show an increase of 16 per
cent. on the last decennial period, while the increase in the
United Kingdom in the ten years preceding the last census was under
11 per cent. This increase appears to be general, and is only
slightly influenced by immigration. "The population of the West
Indies," adds Sir A. Musgrave, "is now greater than that of any of
the larger Australian colonies, and three times that of New
Zealand."
