The radio observations of the 18 cm wavelength OH main lines in comets Kobayashi-Berger-Milon (1975 h) and West (1975 n) confirm the model of ultraviolet pumping by the sun, that we proposed to explain our previous observations of comet Kohoutek (1973 f). The OH scale length in (1975 n) is at least 106 km at a heliocentric distance of 1 AU, in agreement with that for (1973 f).
