and to say when quantities are just right, neither too much nor too
little.

The evil effects of too much are not serious; they entail perhaps a
little "gout" or some temporary loss of freedom from waste products.

The evil effects of too little, if persevered in and continued,
especially if some of these effects are attributed to causes which
have no real existence, are deadly and dangerous, for they bring on an
insidious deterioration both of function and structure which leads by
several avenues, often miscalled "diseases," to death itself.

HEALTHY BRAINS.

_Comparatively few health enthusiasts or food reformers realise the
necessity for mental, as distinct from bodily, hygiene, yet all real
health has its roots in the mind. Moreover, it is only by studying the
hygiene of mind that we are enabled to do work in greater quantity and
of better quality than we should otherwise be capable of, and to do
this without risk of strain on the nerves or injury to health. The
articles under this heading put forward some of the elementary laws of
mental hygiene._--[EDS.]
