Examples

“I should esteem myself in luck, were the nuisances of this seaport confined only to two senses; but, alas! the apartment above my head proves a squalling brattery, and the sounds which proceed from it are so loud and frequent, that a person might think⟳ himself in limbo, without any extravagance.”

“Whole bratteries of little Aarons and Abrahams, who invariably after two years old, but sometimes earlier, develop⟳ the noses and the expressions of their elders, are also airing at the doors.”
