14 Electrodes 5 millims. apart ; carbon separated by the sparks. 



15 Carbon separated by the discharge. 



16 Decomposition by the discharge ; brown vapours evolved. 



17 Electrodes 1 millim. apart ; vibration of longer electrode. 



18 In one direction the 15-millim. sparks strike through with a bright blue colour. Elec- 



trodes 2| millims. apart. ; longer electrode agitated. i9 The liquid turns black. 



20 Vibration of longer electrode ; distance between electrodes 2 millims. 



21 Fusible ; no spark discharge. 22 Distance between electrodes 2 millims. 



23 Fusible at 45° ; slight vibration of longer electrode ; electrodes 3 millims. apart. 



24 Fusible at 42° ; electrodes 4 millims. apart ; gas evolved at the electrodes. 



25 Without spark-discharge a wave motion in the liquid. 



26 Single sparks appear ; electrodes 1 raillirn. apart. 



27 Liquid ; electrodes 3 millims. apart ; liquid coloured brown by the discharge. 



28 Brisk effervescence with the spark-discharge ; liquid turns black. 



29 Distance between electrodes 2 millims. ; deflection of 8°, only with the discharge ; 



feeble vibration of longer electrode. 



30 Fusible at 79° ; electrodes 5 millims. apart ; very bad conductor. 31 Fusible at 43°. 



32 Fusible at 210° ; distance between the electrodes 4 millims.
