EXAMPLE
“…Of acid blood, proclaiming Want’s disease
Amidst the bloom of shew. The scanty stream,
Slow-loit’ring in its channel, seems to vie
With Vaga’s depth; but should the sedgy pow’r,
Vain-glorious, empty his penurious urn
O’er the rough rock, how must his fellow streams
Deride the tinklings of the boastive rill…”
