t a short time. Yet I can easily call to mind every detail
of the surroundings. I can see the exterior of the building,
its form, size, color, window-boxes with flowers, red tile
roof, formal gardens in the open court, and even many of the
neighboring buildings. I can plainly recall the color of the
carpet on his office floor, the general tone of the paper on the
wall, the size, type and material of his desk, and many other
elements going to make up an almost perfect mental duplicate of
the scene itself. I can even see my friend sitting at his desk,
and can distinctly remember the color, cut and texture of his
clothing and just how he looked when he smiled.

[Sidenote: _Imagery of Taste and Smell_]

Last evening we entertained a number of friends at dinner. One of
the ladies was an accomplished musician, and later in the
evening she delighted us with her exquisite playing upon the
piano. The airs she played were familiar to me. I am fond of
music and I enjoyed her playing. I can sit here today and in
imagination I can see her seated before the piano and remember
just how her hands looked as she fingered the keys. But I find it
difficult to recall the air of the selection or the tones of the
piano. My mental images of the notes as they came from the piano
are faint and uncertain and not nearly so distinct and clear as
my recollection of the scene.

I find it easy to recall the appearance of the food that was
served me for breakfast this morning. I can also faintly imagine
the odor and taste of the coffee and toast, but I find that these
images of taste and smell are not nearly so realistic as my
mental images of what I saw and heard during the course of the
meal.

When I was in college I was very fond of handball and was a
member of the handball team. It has been many years since I
played the game, yet I can distinctly feel the peculiar tension
of the right arm and shoulder muscles that accompanied the
"service." Nor do I feel the slightest difficulty in evoking a
distinct mental image of the prickly sensations that so annoyed
me as a boy when I would first put on woolen underwear in the
fall of the year.

[Sidenote: _Personal Differences in Mental Imagery_]

From these examples, it is apparent that we can form mental
images of past sensations of sight, sound, taste, smell and
feeling, and indeed of every kind, including the muscular or
motor sense and the sense of
