That, under the burthen, imposed by the labour of
forming, by means of a description given in the purely verbal mode
of a conception of the figure meant to be presented
to the mind, considerable relief will, very frequently, be
afforded, by a glance at the figure, can not admitt
a doubt. For facilitating conception in the first instance,
the verbal mode and the diagrammatical mode
will thus be employed in conjunction: in conjunction, and, so far with perhaps,
with not very unequal advantage.

In comparison with the diagrammatical mode 19

case of error, without possibility of correction,

which any correction can apply.
