Another extract from "Crotchet Castle":

Whether, in his interior mind, he was at all influenced, either by the consideration that it would be for the credit of his cloth, with some of his vice-suppressing neighbours, to be able to say that he had expostulated; or by curiosity, to try what sort of defence his city-bred friend, who knew the classics only by translation, and whose reason was always a little ahead of his knowledge, would make for his somewhat ostentatious display of liberality in matters of taste; is a question, on which the learned may differ: but, after having duly deliberated on two full-sized casts of the Uranian and Pandemian Venus, in niches on each side of the chimney, and on three alabaster figures, in glass cases, on the mantelpiece, he proceeded, peirastically, to open his fire.

Peirastically: as an experiment or attempt,just to see what would happen.


Bingley

Boy, howdy! They shore did know how to make you forget what they were talking about by the time you got to the end of the sentence. That makes some of *my stuff look positively terse.

Dear Bingley: the Pavonian dictionary gives "tentatively"
for pierastically. Perhaps compatible with definition you gave.
