    "abstract": "On the basis of Galilean invariance and the Doppler formula, combined with an\nobservational condition, it is shown that the constancy of the velocity of\nlight {\\it in vacuo} can be derived, together with time-dilatation and Lorentz\ncontraction. It is not necessary to take the constancy as a postulate.",
