Verse criticism

While I'm sure that some of us have, on occasion, written grumpy comments in the margins or on the endpapers of our books, I suspect that we normally don't do so in verse.  I've just acquired a bound collection of fifteen pamphlets on the Catholic Emancipation Act, which includes the following lines, written on an otherwise blank sheet:

Ah! truth thou'rt a nominal thing

Thy footsteps on earth are unknown

Thy semblance has nought but a sling

Thy light unto darkness is grown

The logic contain'd in this book

Is such as in Bedlam we find

T'is faulty wherever we look

And shows a distempered mind

It's not clear which pamphlet aroused the writer's ire.  The pamphlet immediately following this insert, by the Rev. James Mitchell, is annotated, but in a different hand; since the annotations are proofreader's corrections, the hand in question may well be Mitchell's.
