hydrate evolved ammonia from it, and it was readily soluble in

Since it differs entirely from taurin in its properties, it follows 
that taurin cannot be the amide of isethionic acid—Ber. Berl.

5. Condensation of Acetylene by the Silent Electric Discharge. 
—P. and A. Tuenarp have succeeded in condensing acetylene gas 
to the liquid and even to the solid condition by submitting it to the 
silent electric discharge or “effluve,” in an apparatus contrived by 
the latter. In one experiment, the gas condensed at the rate of
