Adsorption of helium on activated charcoal has been measured in the pressure range 1-30 atm\* and in the temperature range 15-70 K. A Clapeyron like law (InPs = A + B/T) for fictitious saturation vapour pressure P, above Tcr is deduced experimentally from the measurements. This law leads to a fairly
