He then, in a strain of humour beyond description, abused me for putting Newton's head into my picture,--'a fellow,' said he, 'who believed nothing unless it was as clear as the three sides of a triangle. And then he and Keats agreed he had destroyed all the poetry of the rainbow by reducing it to the prismatic colours. It was impossible to resist him, and we all drank 'Newton's health, and confusion to mathematics.' It was delightful to see the good-humour of Wordsworth in giving in to all our frolics without affectation and laughing as heartily as the best of us. By this time other friends joined, amongst them poor Ritchie who was going to penetrate by Fezzan to Timbuctoo. I introduced him to all as 'a gentleman going to Africa.' Lamb seemed to take no notice; but all of a sudden he roared out, 'Which is the gentleman we are going to lose?' We then drank the victim's health, in which Ritchie joined. In the morning of this delightful day, a gentleman, a perfect stranger, had called on me. He said he knew my friends, had an enthusiasm for Wordsworth and begged I would procure him the happiness of an introduction. He told me he was a comptroller of stamps, and often had correspondence with the poet. I thought it a liberty; but still, as he seemed a gentleman, I told him he might come. When we retired to tea we found the comptroller. In introducing him to Wordsworth I forgot to say who he was. After a little time the comptroller looked down, looked up and said to Wordsworth, 'Don't you think, sir, Milton was a great genius?' Keats looked at me, Wordsworth looked at the comptroller. Lamb who was dozing by the fire turned round and said, 'Pray, sir, did you say Milton was a great genius?' 'No, sir; I asked Mr Wordsworth if he were not.' 'Oh,' said Lamb, 'then you are a silly fellow.' 'Charles! my dear Charles!' said Wordsworth; but Lamb, perfectly innocent of the confusion he had created, was off again by the fire. After an awful pause the comptroller said, 'Don't you think Newton a great genius?' I could not stand it any longer; Keats put his head into my books. Ritchie squeezed in a laugh. Wordsworth seemed asking himself, 'Who is this?' Lamb got up, and taking a candle, said, 'Sir, will you allow me to look at your phrenological development?' He then turned his back on the poor man, and at every question of the comptroller he chaunted-- Diddle diddle dumpling, my son John Went to bed with his breeches on.
