Then too 'tis thine to see
How many things oppressive be and foul
To man, and to sensation most malign:
Many meander miserably through ears;
Many in-wind athrough the nostrils too,
Malign and harsh when mortal draws a breath;
Of not a few must one avoid the touch;
Of not a few must one escape the sight;
And some there be all           to the taste;
And many, besides, relax the languid limbs
Along the frame, and undermine the soul
In its abodes within.
