 tory, of poetry. But some important incidents in 

 Voltaire's life, beside his literary successes, happened

 sister, of whom he appears to have been fond, had 

 died while he was in England, leaving a son and two

 Berlin, and would have almost let him dictate his 

 own terms ; but as long as Madame du Chatelet 

 lived, these offers were frankly and peremptorily re-
