Florence Nightingale is quoting someone she presents here as speaking uneducated English. Whether she is inventing the details of this dialog we don’t know. I also don’t know whether this kind of phrasing was, in the mid-19th century, typical of uneducated women in Britain, or perhaps of Cockney dialect.
