-book coloured in the way I
have described, which I might have used as a child. I do not
associate any idea of colour with musical notes at all, nor with any
of the other senses."

She adds:--

"Perhaps you may be interested in the following account from my
sister of her visual peculiarities: 'When I think of Wednesday I see
a kind of oval flat wash of yellow emerald green; for Tuesday, a
gray sky colour; for Thursday, a brown-red irregular polygon; and a
dull yellow smudge for Friday.'"

The latter quotation is a sample of many that I have; I give it
merely as another instance of hereditary tendency.

I will insert just one description of other coloured letters than
those represented in the Plate. It is from Mrs. H., the married
sister of a well-known man of science, who writes:--

"I do not know how it is with others, but to me the colours of
vowels are so strongly marked that I hardly understand their
appearing of a different colour, or, what is nearly as bad,
colourless to any one. To me they are and always have been, as long
as I have known them, of the following tints:--"

A, pure white, and like china in texture.

E, red, not transparent; vermilion, with china-white would represent
it.

I, light bright yellow; gamboge.

O, black, but transparent; the colour of deep water seen through
thick clear ice.

U, purple.

Y, a dingier colour than I.

"The shorter sounds of the vowels are less vivid and pure in colour.
Consonants are almost or quite colourless to me, though there is
some blackness about M.

"Some association with U in the words blue and purple may account
for that colour, and possibly the E in red may have to do with that
also; but I feel as if they were independent of suggestions of the
kind.

"My first impulse is to say that the association lies solely in the
sound of the vowels, in which connection I certainly feel it the
most strongly; but then the thought of the distinct redness of such
a [printed or written] word as '_great_' shows me that the relation
must be visual as well as aural. The meaning of words is so
unavoidably associated with the sight of them, that I think this
association rather overrides the primitive impression of the colour
of the vowels, and the word '_violet_' reminds me of its proper
colour until
