The Boston Commonwealth says that Emma Snodgrass arrived in town, on Tuesday afternoon, from her tour East and North. She was still in her breeches, and made quite a sensation at the South-end, where she appeared. In the evening she went to the Museum, sporting a model cane, Kossuth hat, frock coat, pants, &c., not to mention an ambitious shirt-collar and flaming scarf. Finding she was too generally recognized, she left "Uncle Tom's Cabin" at the third act.
