In continuation of Part I the He circuit with its auxiliaries, the method of purification of He, its distribution and its storage are described. For the performance of low temperature experiments separate ``stations'' are provided, consisting each of a ventilated compartment which is connected with the necessary gas and vacuum systems. Each station contains a liquefier as an integral part of the particular apparatus designed for one type of experiment. The general design of these stations and the detail of the construction of one built especially for x‐ray spectroscopy at low temperatures is described. The equipment for potentiometric measurements is centralized; its arrangements, the thermometric methods and the system of communication between stations and potentiometers is described.
