    Notes: Abstract Hadron mass differences are related to the divergences of the weak hadronic vector currents. The nearly conservedSU(3)-charges are used to understand the approximate validity of mass formulae. We present a simple argument —involving the formal quark structure of the relevant operators —for octet dominance and predict equald/f-ratios for the strong mass differences and the leading part of the electromagnetic mass splitting. Furthermore, mass formulae connecting differentSU(3)-multiplets are derived. A remarkable universality property of the coupling of the various particles to the divergences is observed by which even baryon and meson mass differences are related.
