alleviating circumstances

References in classic literature ?
The only alleviating circumstance in a tete-a-tete with uncle Pullet was that he kept a variety of lozenges and peppermint-drops about his person, and when at a loss for conversation, he filled up the void by proposing a mutual solace of this kind.
The alleviating circumstances include the stable banking sector, the small economy, the tax incentives for attracting investments, the effective one stop shop, the fast registration of firms as well as the cheap labor force.
