ed their natural homes in the arrangement shown in
the figure, which had come to him from some unknown source.

The remaining Figs., 25-28, in Plate I., sufficiently express
themselves. The last belongs to one of the Charterhouse boys, the
others respectively to a musical critic, to a clergyman, and to a
gentleman who is, I believe, now a barrister.

DESCRIPTION OF PLATE II.

Plate II. contains examples of more complicated Forms, which
severally require so much minuteness of description that I am in
despair of being able to do justice to them separately, and must
leave most of them to tell their own story.

Fig. 34 is that of Mr. Flinders Petrie, to which I have already
referred (p. 66).

Fig. 37 is by Professor Herbert McLeod, F.R.S. I will quote his
letter almost in full, as it is a very good example:--

"When your first article on visualised numerals appeared in _Nature_,
I thought of writing to tell you of my own case, of which I had
never previously spoken to any one, and which I never contemplated
putting on paper. It becomes now a duty to me to do so, for it is a
fourth case of the influence of the clock-face. [In my article I had
spoken of only three cases known to me.--F. G.] The enclosed paper
will give you a rough notion of the apparent positions of numbers in
my mind. That it is due to learning the clock is, I think, proved by
my being able to tell the clock certainly before I was four, and
probably when little more than three, but my mother cannot tell me
the exact date. I had a habit of arranging my spoon and fork on my
plate to indicate the positions of the hands, and I well remember
being astonished at seeing an old watch of my grandmother's which
had ordinary numerals in place of Roman ones. All this happened
before I could read, and I have no recollection of learning the
numbers unless it was by seeing numbers stencilled on the barrels in
my father's brewery.

"When learning the numbers from 12 to 20, they appeared to be
vertically above the 12 of the clock, and you will see from the
enclosed sketch that the most prominent numbers which I have
underlined all occur in the multiplication table. Those doubly
underlined are the most prominent [the lithographer has not rendered
these correctly.--F. G.], and just now I caught myself doing what I
did not anticipate--after doubly underlining some of the numbers, I
found that all the multiples of 12 except 84 are so marked. In the
sketch I have writ
