Before discussing these results we give similar tables cal- 

 culated and read from numbers given in the Messrs. Natan- 

 sons's memoir on nitric peroxide (Wiedemann's Annalen, 1886, 

 p. 606). As their results are stated as vapour-densities, we 

 have converted their numbers into volumes of 1 gram.
