Boswell himself explains the visit to Lord Monboddo: 'I knew Lord Monboddo and Dr. Johnson did not love each other; yet ... I was curious to see them together.' It could hardly be supposed that Boswell adopted this attitude without encountering some opposition from Dr. Johnson. The latter evidently wished that a good life of him should be written, and was pleased with Boswell's journal and glad to tell him from time to time about his early life; but there were limits to his endurance. 'I will not be put to the _question_. Don't you consider, Sir, that these are not the manners of a gentleman? I will not be baited with _what_ and _why_; what is this? what is that? why is a cow's tail long? why is a fox's tail bushy?' 'Sir,' he said on one occasion, 'you have but two topicks, yourself and me. I am sick of both.' Boswell indeed was continually taking risks; he compares himself to 'the man who has put his head into the lion's mouth a great many times:' his ordinary method of conversing with Johnson was to push his inquiries to the furthest possible point. His courage in this respect must have been notorious. 'I won a small bet,' he relates on one occasion, 'from Lady Diana Beauclerk, by asking him as to one of his particularities, which her Ladyship said I durst not do. It seems he had been frequently observed at the Club to put into his pocket the Seville oranges, after he had squeezed the juice of them into the drink which he had made for himself. Beauclerk and Garrick talked of it to me, and seemed to think he had a strange unwillingness to be discovered. We could not divine what he did with them; and this was the bold question to be put.' Boswell on this occasion was not successful in his inquiries; but it is to be observed that Boswell was deputed to inquire, and that he asked the question, and won his bet.
Occasionally Boswell remarks that Johnson was not in a good humour for talking. He must have wondered at such times how long it would take before his irritation would break forth, and he would make some typical utterance. 'But I wonder, Sir,' &c., was a sort of Boswellian formula to be met sooner or later with: 'Sir, you _may_ wonder,' or some similar retort.
