collect distinct notes on various subjects, as well as particular
descriptions of interesting objects, and when I cannot meet with a
friend to act as my amanuensis, I have still a resource in my own
writing apparatus, of which, however, I but seldom avail myself, as the
process is much more tedious to me than that of dictation. But these
are merely rough notes of the heads of subjects, which I reserve to
expatiate upon at leisure on my return to old England.

The invention of the apparatus to which I allude is invaluable to those
who are afflicted with blindness. It opens not only an agreeable source
of amusement and occupation in the hours of loneliness and retirement,
but it affords a means of communicating our secret thoughts to a
friend, without the interposition of a third party; so that the
intercourse and confidence of private correspondence, excluded by a
natural calamity, are thus preserved to us by an artificial substitute.
By the aid of this process, too, we may desire our correspondent to
reply to our inquiries in a way which would be quite unintelligible to
those to whom the perusal of the answer might be submitted. This
apparatus, which is called the "Nocto via Polygraph," by Mr. Wedgwood,
the inventor, is not only useful to the blind, but is equally capable
of being rendered available to all persons suffering under diseases of
the eyes; for, although it does not assist you to commit your thoughts
to paper with the same facility that is attained by the use of pen and
ink, it enables you to write very clearly and legibly, while you have
the satisfaction of knowing that you are spared all risk of hurting
your sight. It is but an act of justice to refer such of my readers as
may feel any curiosity on this subject, to Mr. Wedgwood, for full
particulars respecting his various inventions for the use of the blind.

Having given these personal explanations--rendered necessary by the
