The density of He4 under its own vapor pressure has been measured between 1.2°K and 4.4°K by a direct method. The results are given in smoothed tabular form and are compared with the results of previous measurements. An attempt has been made to derive a usable value for the critical density from the liquid and vapor densities at lower temperatures.
