An anecdotal remark:
In his introduction, Mouzin writes that "in England,
Children learn to use [the slide rule] at the same time as they learn to read".
However, it is doubtful because a few years later, Augustus de Morgan, an English mathematician, wrote
“nine Englishmen out of ten would not know what the instrument was for if they saw it, and that of those who
even know what is it for, not one in a hundred would be able to work with a simple question by means of it.”
(Penny cyclopoedia)
He alludes to the cursor (which he does not call by that name) at the end of his manual : "A copper piece that can slide along the slide rule is sometimes added. This allows for a more precise alignment of the lines on the top line with those on the sine and tangent lines. It can also be used to mark the point reached by a first calculation when a second calculation is needed to arrive at the result."
