%X Measurements are reported of the slope of the critical locus of binary mixtures of a series of hydrocarbons, and two fluorocarbons, with hydrogen near the critical point of the hydrocarbon (or fluorocarbon).These systems exhibit gas-gas immiscibility of the first kind. The results are compared with predictions from the one-fluid model together with 'a hard sphere + attractive term' equation of state proposed by Guggenheim.  The results can be predicted from the theory provided the energy interaction parameter, &#958;, is allowed to be somewhat less than that calculated from the Hudson and McCoubrey rule. This is discussed in terms of values of &#958; from other measurements, and possible deficiencies in the theory.
