ME. P. GEIESS ON A NEW SEEIES OF BODIES IN 
If no crystals are formed after the bromine has evaporated in the manner described, 
but only a crystalline mass of perbromide and tribromaniline, the latter is pressed 
between bibulous paper, and then washed with ether in order to separate the two 
compounds. This, however, cannot be done without incurring a considerable loss of 
perbromide, since by the action of the ether it is partly converted into the nitrobromo- 
benzol. Thus prepared it gave on analysis the following results : — 
0-548 grm. gave 0*3895 grm. of carbonic acid and 0-0565 grm. of water. 
0-363 grm. gave, on ignition with lime, 0-5275 grm. of bromide of silver.

differs from the a compound by crystallizing invariably in orange-coloured needles which 
fuse at 52° C., and consequently much below the fusing-point of the a compound. It 
is likewise somewhat soluble in hot water, from which it crystallizes on cooling in 
whitish needles, which closely resemble those of the a diazonitrobenzolimide recrystal- 
lized also from hot water. It somewhat possesses the odour of nitrobenzol. 
0-4317 grm. of substance gave 0*6927 grm. of carbonic acid and 0*1008 grm. of water.
