With which the Doctor paid off an old pox,
By borrowing a new one from an ox.
Bread has been made (indifferent) from potatoes;
And galvanism has set some corpses grinning,
But has not answer'd like the apparatus
Of the Humane Society's beginning
By which men are unsuffocated gratis:
What wondrous new machines have late been spinning!
I said the small-pox has gone out of late;
