0.3245 gr. of substance gave 0.3488 gr. AgBr. 



Calculated for (C 7 H ti Br) 8 N. Found. 



Bromine 45.80 45.73 



It forms small prisms with an adamantine lustre, melting at 121 £°— 

 122° and subliming in oily drops; almost insoluble in H 2 and alco- 

 hol ; slightly soluble in cold, freely in hot ligroine, and in ether and 

 benzol. 



Triorthobrombenzylamine Chlorplatinate, [(C 6 H 4 BrCH 2 ) 3 NH] 2 PtCl 6 , 

 made by adding chlorplatinic acid to an ethereal solution of the amine, 

 gave the following result on analysis : — 



0.39708 gr. of the salt gave 0.0540 gr. Pt. 



Calculated for [(C 7 H 6 Br) 8 NH],PtCl 6 . Found. 

 Platinum 13.51 13.G0 



A whitish yellow, barely crystalline precipitate, insoluble in water 

 and ether, and very slightly, if at all, soluble in alcohol. 



On boiling the tertiary amine with dilute alcohol and hydrochloric 

 acid, it dissolved, and on cooling deposited white spheres made up of 

 radiated needles ; but an analysis of the substance gave an amount of 

 chlorine too low for the pure chloride, and we did not think the com- 

 pound of sufficient importance to study it further.
