One anguish in a crowd

One Anguish - in a Crowd -
A minor thing - it sounds -
And yet, unto the single Doe
Attempted - of the Hounds

Tis[^a1] Terror as consummate
As Legions of Alarm
Did leap, full flanked, opon the Host -
'Tis Units - make the Swarm -

[^a1: Tis | 'Tis]

A small Leech - on the Vitals -
The sliver, in the Lung -
The Bung out - of an Artery -
Are scarcecomputed accounted - Harms -

ButYet mighty - by relation
To that Repealless thing -
A Being - impotent tostop - end -
When once it has begun -
