New Test for Aloes. —Hugo Borntraeger has recently 
described a test for the detection of aloes, which we have no 
doubt will prove extremely useful. The liquid, or the cold 
alcoholic extract of the suspected solid, is shaken up with 
about twice its bulk of benzol. The benzol, which, in the 
presence of aloes, assumes a yellowish-green colour, is taken 
off with a pipette, and agitated with a little strong ammonia. 
The ammonia will now assume a fine violet-red colour, even
