Abstract
It is shown that for any Petrov type III, shear-free, perfect-fluid so lution of Einstein's field equations, in which the perfect fluid satis fies a barotropic equation of state p = p(w) such that w + p not equal 0, the fluid volume expansion is zero. In addition, the fluid must ne cessarily be rotating.
