painted the sky rose-colour, and roses blue.
Mr. L ., a bookseller, had a boy who matched
pale green with pink, and brought him into
frequent trouble by binding books in wrong
colours. Mr. M., who is a good draughtsman,
painted a face muddy green; and Mr. M.'s
brother cannot distinguish by gaslight
between the various brightly-coloured bottles
in a chemist's window.

Of the family of N., six members – uncles,
nephews, and cousins – are to a remarkable
extent colour-blind. They are Quakers. One
of them desiring a brown coat, bought
himself a bottle-green one; and intending to
purchase for his wife a quiet, dark dress, bought
her a scarlet merino. Another, who is an
upholsterer, cannot tell scarlet from drab,
and upon all matters of colour consults
persons in his employment. Mr. O. is a
minister in the Society of Friends, who
selected scarlet cloth as suitable material for
his Sunday coat.

Mr. P. is a tailor's foreman, who knew
nothing of his colour-blindness till, after
excelling as a cutter, he had been promoted to
his present post. He then had to match
colours for the journeymen, and his distresses
began. The scarlet back of a livery coat was
provided with green strings to match. A
purchaser was informed that a red and blue
stripe on a piece of trouser cloth was all
blue; and in general, greens were confounded
with reds and browns, crimson with blue.
He would give any reasonable sum to be
cured of his defect; but his defect is one that
appears to be in all cases incurable, and
capable of alleviation by the use of coloured
spectacles only to a very limited extent
indeed.

The Countess of Q., describing her case in
October, says, that the yellow tints now seen
on the trees appear to me exactly the same
as those of their spring shades; indeed, I
cannot conceive the possibility of any one
seeing them to be different." Here the term
yellow includes all the autumnal tints, and
they are regarded as identical with the bright
green of spring.

It was observed of Miss Q., in a drawing-
class, that she was obliged to help her
discrimination of the colours, when not marked
with their names, by placing them upon her
tongue, and that when she had tints to
compound she was entirely at a loss, and trusted
wholly to the help afforded by her teacher.

Mr. R., a surgeon, thrown from his horse,
suffered concussion of the brain. In
consequence of this, he became to a marked degree
colour-blind, and still recals the shock he
experienced on first entering his garden after
his recovery, at finding that a favourite
damask rose had become in all its parts –
petals, leaves, and stem – of one uniform dull
colour. Add to this the case of a gentleman
to whom, while he was suffering some hours
from a sense of giddiness, the whole population
in the street seemed to be dressed in green.

S. was an artillery soldier at Leith Fort,
who, being shown a square of chrome yellow
paper, at once declared it to be purple, This
is a rare kind of error. The same soldier,
when asked to select the purple skeins from a
large bundle of coloured wools, began with
the chrome yellow, and held that in his hand
as his best guide, while matching it successively
with orange, pink, crimson, red-purple,
and purple-brown, as if feeling his way from
yellow to purple, which, however, at the last
he did not reach. He stopped at the purple-
brown, and continued, without saying a word,
to retain the yellow skein in his hand, as if it
came the nearest to his view of purple.

Mr. T., mistaking red flakes of paint upon
the pavement for soot, remarked to a
companion with whom he walked, that a chimney
must have been on fire. He has also
supposed a lady to have gone into mourning who
put on a crimson velvet bonnet.

Mr. U., a clerk in the Edinburgh post-
office, has sometimes surprised his superiors
by signing official papers in red ink, this
having happened when he has neglected to
distinguish between red ink and black in the
only way possible to him, by the smell.

Mr. V., a banker near London, frequently
annoyed by the results of his own inability to
distinguish by the colour between black ink
and red, had each ink put into a bottle
different in shape, in order to insure himself
against farther mistakes.

Mr. W., in early life, was apprenticed to
an undertaker, and being sent to buy some
black cloth for a coffin, he brought scarlet.
Add to this the case of a young surgeon, who,
before sealing a letter, had to ask which was
the red and which the mourning wax.

X., a tailor's journeyman, having received
a young gentleman's dark blue coat for
immediate repair, very much surprised the
mother of the youth by taking it home with
a scarlet patch let in at the elbow. This
person made many similar mistakes,
whenever by chance left to his own judgment of
colours.

Captain Y., an officer in the navy,
purchased a blue uniform coat and waistcoat,
with red breeches to match.

Finally Z., who shall be Dalton himself,
writes thus: " All crimsons appear to me to
consist chiefly of dark blue; but many of
them seem to have a strong tinge of dark
brown. I have seen specimens of crimson,
claret, and mud, which were very nearly
alike. Crimson has a grave appearance, being
the reverse of every showy and splendid
colour. Woollen yarn, dyed crimson or
dark blue, is the same to me." Again: " The
colour of a florid complexion appears to me
that of a dull, opaque, blackish blue, upon a
white ground. Dilute black ink upon white
paper, gives a colour much resembling that
of a florid complexion."

Here is an alphabet of colour-blindness,
which any person may extend out of his own
