It is noted that low-mass stars cannot by themselves provide all the information needed to determine all the primordial abundances of D, He-3, He-4, and Li-7. Nevertheless, they play a basic role in establishing the primordial abundance of Li-7 and they may provide a useful constraint on the chemical models of the Galaxy (e.g., that of Delbourgo-Salvador et al., 1985) to reconcile the baryonic densities deduced from He-4 and D. Furthermore, they may constrain the primordial abundance of He and compel the cosmologist to adopt for it a low value which may be inconsistent with the prediction of the standard big bang nucleosynthesis.
