In this letter, Frederick wishes that the “hot fever” of Europe would recover soon. He tells Voltaire that he himself is no longer sick in body or mind. The end of the letter turns political as Frederick addresses the Austrians directly, telling them that their ambition and their desire to dominate everything actually created more enemies for them, and that there will always be defenders of German and European liberties. This is probably a reference to the Seven Years War, which was fought from 1754-1763.

Voltaire explains that the delay in his response was caused by his Niece’s illness as she was the one transmitting his letter. He discusses the misfortune shared by disloyal people, noting that ‘misfortune lyes on those who violate the laws of mankind.’ He informs Rolt that he can count him in the rank of subscribers as well as in the rank of his friends because he likes his works and way of thinking, and adds that if his health was better he would come to ‘breath the air of liberty in england.’ Voltaire concludes by saying that he his happier in the French countryside than at court and states that he is less proud of his title as a gentleman of the King’s chamber than he is the status of being Rolt’s friend.

Richard Owen Cambridge opens the letter with a mention of the Wilkes disturbances in London and goes on to talk about how the people of Geneva are ‘abandoning the foolish notions of liberty put into them by Rouisseau and fomented by Voltaire’.
