The memoirs of that day abound in references to an exodus which has left other and more material evidence in those fallen and ravaged mansions which now constitute the worst slums of our capital city.
One figure may be cited by way of illustration.

Before the Union "98 Peers, and a proportionate number of wealthy Commoners" lived in Dublin.
The number of resident Peers in 1825 was twelve.

At present, as I learn from those who read the sixpenny illustrateds, there is one.

But when they abandoned Ireland they did not leave their rents behind.

And it was a time of rising rents; according to Toynbee they at least doubled between 1790 and 1833.
