But the highstrung Bozzy had to experience a revulsion of low feelings to which he was ever prone. He is soon in a sort of Byronic fit, and he continues in a strain with which we should have not credited the 'gay classic friend of Jack Wilkes' and of that Sienese _signora_, unless he had turned evidence against himself. He declared his feelings to Paoli, as he had done to Johnson, whose curt advice had been not to confuse or resolve the common consequences of irregularity into an unalterable decree of destiny. To the general he now attributed his feeling of the vanity of life, the exhaustion in the very heat of youth of all the sweets of being, and the incapacity for taking part in active life to his 'metaphysical researches,' his reasoning beyond his depth on such subjects as it is not given to man to know. These hesitances the other wisely pushed aside with the soldierly advice to strengthen his mind by the perusal of Livy and Plutarch. In return Bozzy gave an imitation of 'my revered friend Mr Samuel Johnson,' little dreaming that all three would one day be intimate in London, and the general's house in Portman Square be always at the traveller's disposal. From the palace, as he styles it, of Paoli, Nov. 1765 he wrote to Johnson, as he had done before, 'from a kind of superstition agreeable to him as to myself,' from what he calls _loca solennia_--places of solemn interest. 'I dare to call this a spirited tour. I dare to challenge your approbation;' and, reading it twenty years later in the original which the old man had preserved, he found it full of 'generous enthusiasm.' No account of the continental travels of Boswell would be complete without the reproduction of his letter to the doctor from Wittenberg. It is one of the most important for the more subtle shades of psychology in the writer's character. '_Sunday, Sept. 30, 1764._
