COMMON FROG. Oi 
development of the young, is not so for the existence and 
health of the perfect animal. 
Of the existence of the Frog in Ireland very erroneous

‘The Lord have mercy upon us’), spread faster and farther 
than the colony of Frogs. ‘To this passage, one of Swift’s 
editors, I believe Sheridan, adds the following note :—
