tween each of which were traced lines with a pen and
black ink; there were also perpendicular red lines, between
■which were scored black lines. All these, with their direc-
tion and order, she determined without any apparent diffi-
culty. She also told correctly the colour of a variety of
pieces of cloth, procured immediately before at a draper’s
shop. All the experiments hitherto described, as well as
those which follow, were performed by Miss M‘Avoy, with
the bandage before her eyes; and as the shawl, which was
usually applied to this purpose, produced considerable
warmth and inconvenience, a pair of what, in the opticians’
shops are called gogglers, had been provided, which so com-
pletely excluded the light, that no person who tried them,
could discern the difference between day and night, when
they were fitted to the face. As these gogglers have been
generally used, when Miss McAvoy has exhibited her surprising
talent, it is necessary that the reader should have a correct
idea of them. They are intended to be worn by travellers,
to guard the eyes against the wind or the dust, and consist
of two glasses, sometimes green, fitted into a bandage of
Leather, which is passed horizontally across the face, and is
tied with ribbons round the back of the head. The gog-
glers provided for Miss M'Avoy instead of glasses, were fitted
up with opaque pasteboard, lined with paper, and not an
aperture was left through which a single ray of light could
penetrate. [ We exhibit the same, as worn by Miss MMvoy
in a plate accompanying this account.'] Mr. Nichol, a
scientific gentleman, who was delivering a course of philo-
sophical lectures in Liverpool, having heard of this extraor-
dinary property, applied to me to obtain an introduction to
Miss M‘Avoy, and I accompanied him to her house, along
with Mr. James Smith, printer, of this town. At this inter-
view the experiments 1 have already detailed were repeated,
and with complete success, whilst the gogglers were applied.
One part of the performance was so truly astonishing, that I
should almost hesitate to relate it, if those two gentlemen
