THESE experiments have led TO tne
conclusion that there are certain polsons
that result from the activities Oh tne
cell which have been given the na'ne
of fatigue poisons." These faugue

Both forms of fatigue, however, are
due to poisoning. There is in the nraln

proper rest. especially IL accompanied

liver and kidneys to destroy and remove

The pofsons that give rise to chronic
| fatigue are the result of the putrefac-
| ton of undgested and unused foodstuffs
in the colon, and particularly undi-
gested remnants of flesh food. This eN-
plains why one feels languid and tired
when Constipated, even when he has not
worked II is also the cause of the great
exhaustion and weakness in person
suffering from diarrhea, or looseness Of
the bowels.
Inconsistencies are often continually
tired, frequently TO the point of exhaus-

such cases the fatigue is due to the
poisonS resulting from chronic colltis or
other infections of the colon.
Constipation is a much more common
cause OF fatigue than is overwork Many
