Summary: Newton's formula for constructing the interpolation polynomial is well-known. It makes use of divided differences. It was generalized around 1971-1973 by M$\ddot $uhlbach for interpolation by a linear family of functions forming a complete Chebyshev system. This generalization rests on a generalization of divided differences due to Popoviciu. In this paper, it is shown that M$\ddot $uhlbach's formula is related to the work of Andoyer which goes back to the beginning of the century.
