Comments made in the preceding paper are critically discussed. It is argued that conclusions reached in our earlier papers were conservative and justified within our experimental accuracy. Negative-ion yields under cesium bombardment scale with surface cesium concentration and electron affinity in a manner analogous to the scaling of positive-ion yields with surface oxygen concentration and ionization potential. Fluorine is shown to be an exception, due probably to saturation effects.
