Did Jevons and Walras make any claim about social utility?

Professor Hülsmann associates Jevons and Walras line of economic thought with the Gossen School of economics. In this he is entirely right.

However, Gossens theory involves a social utility function. Utility could be added and subtracted between individuals to show “their utility function”.

Did Jevons and Walras accept such claim could be made about a social utility function? I personally don’t think Jevons made any statement about a social utility function.

Jevons also denied the possibility of making interpersonal comparisons of utility, pointing out that price theory did not require such comparisons

As I understand the issue, Jevons denied direct interpersonal comparison of utility, but accepted indirect comparison via money.
