Extract
So far as mathematical writers have as yet noted, a set of equations of the type
had not made its appearance in mathematical work prior to the year 1846: and it is almost absolutely certain that before that year the determinant of such a set had never been considered. It is not at all unlikely, however, that the expression
which is the case of the determinant for n equal to 3 had more than once turned up in other connections, and that its divisibility by a + b + c had been noted: but of this, too, there is no record.

separating out the factor n, and then showing that the resulting determinant is ( − 1)n−1Δ.
