ve--a mere internal glimmering. The most we can
say of such physiological suggestion is, that there is probably some
consciousness, and that the ordinary reflexes seem to be abbreviated
and improved.

_Subconscious Adult Suggestion._--There are certain phenomena of a
rather striking kind coming under this head whose classification is so
evident that we may enumerate them without discussion of the general
principles which they involve.

_Tune Suggestion._--It has been pointed out recently that dream states
are largely indebted for their visual elements--what we see in our
dreams--to accidental lines, patches, etc., in the field of vision
when the eyes are shut, due to the distended blood vessels of the
cornea and lids, to changes in the external illumination, to the
presence of dust particles of different configuration, etc. The other
senses also undoubtedly contribute to the texture of our dreams by
equally subconscious suggestions. There is no doubt, further, that our
waking life is constantly influenced by such trivial stimulations.

I have tested in detail, for example, the conditions of the rise of
so-called "internal tunes"--we speak of "tunes in our head" or "in our
ears"--and find certain suggestive influences which in most cases
cause these tunes to rise and take their course. Often, when a tune
springs up "in my head," the same tune has been lately sung or
whistled in my hearing, though quite unnoticed at the time. Often the
tunes are those heard in church the previous day or earlier. Such a
tune I am entirely unable to recall voluntarily; yet when it comes
into the mind's ear, so to speak, I readily recognise it as belonging
to an earlier day's experience. Other cases show various accidental
suggestions, such as the tune Mozart suggested by the composer's name,
the tune Gentle Annie suggested by the name Annie, etc. In all these
cases it is only after the tune has taken possession of consciousness
and after much seeking that the suggesting influence is discovered.

Closer analysis reveals certain additional facts: The "time" of such
internal tunes is usually dictated by some rhythmical subconscious
occurrence. After hearty meals it is always the time of the heart
beat, unless there be "in the air" some more impressive stimulus; as,
for example, when on shipboard, the beat is with me invariably that of
the engine throbs. When walking it is the rhythm of the footfall. On
one occasion a knock of four beats on
