The first line of this table tells us the average of the recorded
improvement in endurance shown for each man. The average of these
averages is 101 per cent. for the entire club, and is probably within
the truth; for most of the individual figures which go to make up this
result are understatements, not overstatements.

The second line shows the average improvement in tests in which there is
no doubt that the figure is at least not too high, though it may be too
low. The average of these is 89 per cent., and is therefore certainly
too low an estimate of the average improvement for the eight men who
improved at all.

The third line shows the increase of _pure_ endurance (that is,
endurance considered apart from strength) for the five men for whom the
figures were available. The average of these is 116 per cent.

We are quite safe in saying, therefore, that the average improvement of
the eight men who improved was 90 per cent.

The phenomena observed during the experiment may be summarized as a
slight reduction of total food consumed, a large reduction of the
protein element, especially of flesh foods, a lessened excretion of
nitrogen, a reduction in the odor, putrefaction, fermentation and
quantity of the feces, a slight loss of weight, a slight loss of
strength, an enormous increase of physical endurance, a slight increase
in mental quickness. These phenomena varied somewhat with different
individuals, the variations corresponding in general to the varying
degree in which the men adhered to the rules of the experiment.

That we are correct in ascribing the results, especially in endurance,
to dietetic causes alone, cannot reasonably be doubted when it is
considered that no other factors of known significance were allowed to
aid in this result.

While the results of the present experiment lean toward "vegetarianism,"
they are only incidentally related to its propaganda. Meat was by no
means excluded; on the contrary, the subjects were urged to eat it if
their appetite distinctly preferred it to other foods.

The sudden and complete exclusion of meat is not always desirable,
unless more skill and knowledge in food matters are employed than most
persons possess. On the contrary, disaster has repeatedly overtaken many
who have made this attempt. Pavlov has shown tha
