The author also studied the spectra of the different oxides of 
nitrogen, but found that these gave only the cannellated spectrum 
hitherto attributed to nitrogen, and which undoubtedly belongs 
only to the oxide of nitrogen formed under the influence of the 
electric spark. Schuster’s results clear away an beggin 
amount of confusion and error. It is to be hoped that they will 
lead to a careful revision ~ the spectra of the other — Lo es.

The oxysulphide of carbon set free was easily recognized by direct 
experiment, but the sulphydric acid and carbonic dioxide are due 
to a secondary reaction expressed by the equation

‘On eymol from oil of terpentine and oil of lemons. _Oprex- 
hoes has also studied the cymols obtained from terpen-bibromide 
and citren-bibromide by heating them with anilin in sealed tubes. 
Both yielded terephthalic and acetic acids; whence it follows that 
the two cymols are identical. Oil of terpen ntine and oil of lemons 
appear, therefore, to be hydrogen compounds of the same cymol,
