the free bromine produced in the reaction by means of antimony, 
it was allowed to condense in the receiver with the bromide, and 
a crude product colored by bromine, was obtained, which weighed 
grams, after repeating the operation fifteen to twent 
times. Subsequently by distilling this through a tube age rrees,2 
antimony, a colorless heavy liquid was collected, Step the sam

whose vapor caused a remarkable swelling up of thé vuleanized
