ther attempting and failing, or not finding any
response in their minds, took no interest in the inquiry." A very
remarkable case of hereditary colour association was sent to me by
Mr. Hill, to which I shall refer later. The only five good cases of
Number-Forms among the 135 boys are those shown in the Figs. I need
only describe Fig. 2. The boy says:--"Numbers, except the first
twenty, appear in waves; the two crossing-lines, 60-70, 140-150,
never appear at the _same time_. The first twelve are the image of a
clock, and 13-20 a continuation of them."

Figs. 7, 8, are sent me by Mr. Henry F. Osborn of Princeton in the
United States, who has given cordial assistance in obtaining
information as regards visualising generally. These two are the only
Forms included in sixty returns that he sent, 34 of which were from
Princeton College, and the remaining 26 from Vassar (female) College.
Figs. 9-19 and Fig. 28 are from returns communicated by Mr. W.H.
Poole, science-master of Charterhouse College, which are very
valuable to me as regards visualising power generally. He read my
questions before a meeting of about 60 boys, who all consented to
reply, and he had several subsequent volunteers. All the answers
were short, straightforward, and often amusing. Subsequently the
inquiry extended, and I have 168 returns from him in all, containing
12 good Number-Forms, shown in Figs. 9-19, and in Fig. 28. The
first Fig. is that of Mr. Poole himself; he says, "The line only
represents position; it does not exist in my mind. After 100, I
return to my old starting-place, _e.g._ 140 occupies the same
position as 40."

The gross statistical result from the schoolboys is as follows:
--Total returns, 337: viz. Winchester 135, Princeton 34, Charterhouse
168; the number of these that contained well-defined Number-Forms
are 5, 1, and 12 respectively, or total 18--that is, one in twenty.
It may justly be said that the masters should not be counted,
because it was owing to the accident of their seeing the Number-Forms
themselves that they became interested in the inquiry; if this
objection be allowed, the proportion would become 16 in 337, or one
in twenty-one. Again, some boys who had no visualising faculty at
all could make no sense out of the questions, and wholly refrained
from answering; this would again diminish the proportion. The
shyness in some would help in a statistical return to neutralise the
tendency to exaggeration in others, but I
