At about one O’clock on Friday afternoon [October 11] a sensational incident occurred in Park Street [in Calcutta]. A bullock cart containing a number of jars full of nitric acid was proceeding from Survey of India Office to the Howrah station when at the crossing of Russel Street and Park Street two jars suddenly caught fire emitting noxious fumes. The local police and fire brigade were immediately communicated with and on arrival of assistance the flames were extinguished by means of mud before they assumed serious proportions.
