1751. 'Curiosity is one of the permanent and certain characteristicks of a vigorous intellect.' Rambler, No. 103. 'Curiosity is in great and generous minds the first passion and the last; and perhaps always predominates in proportion to the strength of the contemplative faculties.' Ib. No. 150.
1752. Francis Barber, describing Johnson's friends in 1752, says:—
'There was a talk of his going to Iceland with Mr. Diamond, which would probably have happened had he lived.' Ante, i. 242. Johnson, in a letter to the wife of the poet Smart, says, 'we have often talked of a voyage to Iceland.' Post, iv. 359 note. Mrs. Thrale wrote to him when he was in the Hebrides in 1773:—'Well! 'tis better talk of Iceland. Gregory challenges you for an Iceland expedition; but I trust there is no need; I suppose good eyes might reach it from some of the places you have been in.' Piozzi Letters, i. 188.
1761. Johnson wrote to Baretti:—
'I wish you had staid longer in Spain, for no country is less known to the rest of Europe.' Ante, i. 365. He twice recommended Boswell to perambulate Spain. Ante, i. 410, 455.
1763. 'Dr. Johnson flattered me (Boswell) with some hopes that he would, in the course of the following summer, come over to Holland, and accompany me in a tour through the Netherlands.' Ante, i. 470.
1772. He said that he had had some desire, though he soon laid it aside, to go on an expedition round the world with Mr. Banks and Dr. Solander. Ante, ii. 147.
1773. 'Dr. Johnson and I talked of going to Sweden.' Boswell's Hebrides, post, v. 215.
On Sept. 9, 1777, Boswell wrote to Johnson:—
'I shrink a little from our scheme of going up the Baltick: I am sorry you have already been in Wales; for I wish to see it.' Ante, iii. 134. Four days later Johnson wrote to Mrs. Thrale:—'Boswell shrinks from the Baltick expedition, which, I think, is the best scheme in our power: what we shall substitute I know not. He wants to see Wales; but except the woods of Bachycraigh (post, v. 436), what is there in Wales, that can fill the hunger of ignorance, or quench the thirst of curiosity? We may, perhaps, form some scheme or other; but in the phrase of Hockley in the Hole, it is a pity he has not a better bottom.' Ib. note 1.
