and to my surprise, found it to be the precise line I had

of the aquatint was obtained from the ingenious Mr.
Craig, in Manchester, I even saw him produce the
aquatinta line, but thus was the dry ground line, and I
believe the invention of the late Paul Sandby,
Esquire; and though there is a considerable difference in
the processes producing the dry and the liquid ground lines,
yet having first known the dry line, I claim no merit in its
production by the liquid ground, though the line produced
from the liquid ground is more beautiful and much more

I had always considered the aquatinta line as an excellent
and expeditious mode of repairing failures in the soft
