The heat of occlusion of hydrogen in platinum black was determined by saturating the platinum black with hydrogen, extracting as much of this as possible at 184°C. by means of the pump, and then readmitting it again whilst the experimental tube was placed in an ice calorimeter. By proceeding in this way, errors due to the preexistence of oxygen in the platinum black were avoided, and it was found that 68.8 K (6880g -calories) were evolved per gram of hydrogen occluded. It is shown that the arguments put forward by Berthelot in favour of the existence of the compounds Pt30 H3 and Pt30 H3 are not justified.
