the country, and frequent visits to the Botanical Garden, with the curator of which, Mr. Stewart Murray, he formed a friendship which continued to the day of his death. Through Mr. Murray, and from his having discovered, in one of his rambles, the rare Nuphar minima or pulima, growing in Mugdock Loch, he became known to Sir William J. Hooker, the eminent professor of botany in the university of Glasgow. He now attended Sir William's botanical lectures, and that truly amiable gentleman soon formed a high estimate of his character and talents. As a student, he made several botanical excursions to the Highlands with the Professor and his class; and to the intimacy thus produced may be attributed the important change in his future career.
From the Faculty of Physicians and Surgeons of Glasgow, Gardner obtained his diploma as surgeon, with high marks of distinction. Meanwhile he had made himself acquainted with the flowering plants of Scotland, and studied cryptogamic botany so successfully that, in 1836, he brought out a work, entitled "Musci Britannici, or Pocket Herbarium of British Mosses," arranged and named according to Hooker's "British Flora." This work was flatteringly received, and has been of great value to muscologists. The specimens are beautifully dried, and neatly attached; whilst its general accuracy can be depended upon, as he had not only free access to the splendid library of Sir William Hooker, but the benefit of his personal assistance.
A copy of the "Musci Britannici" having reached the late Duke of Bedford—well known for the interest which he took in botanical science his grace became a liberal patron, and warmly encouraged his ambition to proceed upon a foreign exploratory mission. After the death of the lamented Drummond, whose labours in Texas and parts of Central America had greatly enriched the Royal Botanic Garden, the directors of that institution were solicitous still further to promote its scientific character; and arrangements were made for his proceeding to North Brazil, to explore the botany of that country. As in the case of Drummond, Sir William Hooker undertook to procure a number of subscribers for the dried specimens, and to be at the trouble of subdividing and forwarding them to the respective parties; the curator, at the same time, agreeing to take a similar charge of the seeds and living plants sent home. Many of the public botanic gardens, as well as a number of amateur noblemen and gentlemen, were subscribers, and by this means, for a moderate sum, had their collections largely and richly increased. Amongst others the Duke of Bedford was a munificent contributor; and all preliminaries having been arranged for Gardner's departure, his grace not only interested his son, Lord Edward Russell, R.N., commanding on the American station, in his behalf, but secured for him a free passage out in one of H.M. ships. This, however, he politely declined, preferring the greater privacy of a merchant ship, that he might have leisure to study, and especially to improve himself in his knowledge of the Spanish and Portuguese languages. So far from being offended, the duke magnanimously sent a draft for ₤50 in lieu of the free passage.
In the summer of 1836 Gardner sailed from Liverpool, and, after a favourable passage, arrived at Rio de Janeiro, with the appearance of which, and the surrounding scenery, he was perfectly captivated, and wrote home in glowing terms, descriptive of his first impressions. Amidst scenes so tempting to a naturalist, Gardner did not long remain inactive. He made frequent excursions in the vicinity of Rio, and particularly to the Organ mountains. In these
