The following are the results which I have obtained; it is well known that the
last or constant function is in each case equal to the discriminant, and as the
expressions for the discriminant of equations of the fourth and fifth degrees are given,
Tables No. 12 and No. 26 [Q', see 143] in my ‘Second Memoir upon Quantics’^), I
have thought it sufficient to refer to these values without repeating them at length.
