1    II|            unto them~ Wherewith to travel down the vast inane:~ Do
2    II| exhalations and this serene light~ Travel not down an empty void;
3    II|            of air;~ Nor one by one travel these particles~ Of the
4    II|          solidity, when forth they travel~ Along the empty void, all
5    IV|      assail the nostrils, some can travel~ A longer way than others.
