The presence of a secondary amine was confirmed by the 

 analysis : — 



I- 0-I355 gi"- substance gave 0.4264 gr. carbon dioxide and 

 0.1138 gr. water, corresponding to 0.1163 gr. C. and 0.01264 

 gr. H. 



II. 0.1255 gr. substance gave 6 cc. moist nitrogen (thermo- 

 meter 22° C, barometer 727 mm.) equal to 0.006494 gr. N.

Accompanying these bases was unchanged thymol, which 

 was isolated and weighed. Corresponding experiments were 

 made with thymol and the chloride of zinc and ammonium. 

 The results of repeated experiment are here given. The 

 proportion of the substances used, as well as the time and 

 temperature, were the same as when the bromides were 

 used. 



Derivatives of Thymylamine. 



The Platinum Double Salt — (Cjo Hj^ N . HCl), Pt CI4— was 

 prepared by dissolving the base in absolute alcohol, adding a 

 small amount of hydrochloric acid, then an alcoholic solution
