Supplemental Notes.
THE foregoing descriptions present a very clear idea
of the position of the Writing Machine, but there
has been a very large number of which the record
ends with the patent specification ; whilst others have been

which we give.
This record will also enable us to mention many special
or exceptional machines as well as a number of other points
and items of interest, particularly to identify machines
which have been issued under varying names in different
countries. In dealing with these machines, we have taken
every possible precaution to ensure accuracy, but it is
obvious that in this, the first attempted complete account
of its kind in the English language, although we have set
down naught in malice, there have been numerous oppor-
tunities for errors to arise. If such there be, we shall at
all times be glad to hear of them ; whilst should any reader
consider too much attention has been given to those machines
which have ceased to exist, we can only say that our motto

the letters placed around a small ball or sphere, 2 inches in
diameter, which is caused to revolve. The letters them-
selves are ranged in six lines converging at the poles. When
it is desired to print a certain letter the inking roller passes
over it. Then the platen presses the paper against the
