Analysis of I read my sentence—steadily

I read my sentence—steadily—
Reviewed it with my eyes,
To see that I made no mistake
In its extremest clause—
The Date, and manner, of the shame—
And then the Pious Form
That "God have mercy" on the Soul
The Jury voted Him—
I made my soul familiar—with her extremity—
That at the last, it should not be a novel Agony—
But she, and Death, acquainted—
Meet tranquilly, as friends—
Salute, and pass, without a Hint—
And there, the Matter ends—
