That the determinant

where hr is the rth complete homogeneous symmetric function in a set of n arguments, is equal to the quotient of a particular pair of alternants was shown essentially by Jacobi in 1841 and by Trudi in 1864. The present note exhinits this well-know relation, (3), as the immediate consequence of a simple matrix equality.
