In a recently published paper I have described a method and apparatus for the optical investigation of crystalline nitrogen and argon and other bodies solidifying at extremely low temperatures.* The determination of the general crystallographic characters of these bodies by crystal-optical methods was also described. The following communication deals with the optical investigation of solid hydrogen and oxygen. In order to liquefy and solidify hydrogen in the crystallisation vessel described in the paper mentioned it is necessary to use liquid and solid hydrogen as cooling agents, and the apparatus for the investigation of nitrogen and argon has accordingly had to be modified. Fig. 1 shows the arrangement of the apparatus used for wording with liquid hydrogen.
