Wise Nature likewise, They suppose,
Has drawn two Conduits down our Nose:
Cou'd  else with Judgment tell,
When  stinks, or  smell?
Or who wou'd ask for her Opinion
Between an , and an ?
For from most Bodies, , You know,
Some little Bits ask Leave to flow;
And, as thro' these Canals They roll,
Bring up a Sample of the Whole.
Like Footmen running before Coaches,
To tell the Inn, what Lord approaches.
