“Found a load of these little glass bottles when we were digging up a lawn in Ireland. What was in them?”
These bottles were used to carry special oil for batteries and accumulators. Thomas Edison invented a nickel-iron accumulator that was later used for the automatic railroad crossing guards. The oil was poured onto electrolytes and created a special protective cover. Unnecessary bottles were thrown away.
