Lives of Eminent Zoologists, from Aristotle to Linnus


Page 44 of 79



Continuing his journey to Holland, he arrived at Harderwyk at the end of May, and made application for his degree, which he received on the 24th June. His thesis was on intermittent fevers, one of the principal causes of which he maintained to be water impregnated with argillaceous substances. Though he had now accomplished his chief object, he resolved, before returning to Sweden, to make himself known to some of the Dutch literati; and for this purpose proceeded to Leyden, where he hired a lodging. Here he made the acquaintance of Professor Royen, Dr Van Swieten, Lieberkuhn, Gronovius, and several others.

By the advice and assistance of the last of these scholars, he published his Systema Naturæ, in fourteen folio pages. This little work, containing a compendious classification of the three kingdoms of nature, was very favourably received. Boerhaave, one of the most illustrious physicians that the world has ever seen, was at the same time the most eminent[Pg 223] individual in the University of Leyden. Linnæus was therefore anxious to see him; but finding an interview impracticable in the ordinary way, on account of the great man's constant occupation, he resolved to send him a copy of his treatise, accompanied with a letter. The consequence was an invitation to meet him at his villa near the city, where he had a botanical garden. On entering into conversation with the young foreigner, the venerable professor, astonished at his knowledge, strongly advised him to remain in Holland, where he might be sure of making a fortune; but the other, prevented by poverty from adopting this counsel, was obliged to set out on the following day.

Arriving at Amsterdam with a recommendation to Professor Burmann, he was kindly received by that gentleman, who was then occupied with his description of the plants of Ceylon. Linnæus himself relates the occurrences which took place during this interview: "'Do you wish to see my plants?' asked Burmann, 'which of them would you inspect?' He held out one, and observed, 'It is very rare.' I begged a single flower, which I examined after softening it in my mouth, and pronounced it to be a species of laurus. 'It is not a laurus,' said Burmann. 'But it is,' said I; 'it is the cinnamon-tree.'—'It certainly is the cinnamon,' rejoined Burmann. I then convinced him that this tree was a species of laurus, and so of other plants. At length he said, 'Will you help me with my work on Ceylon, and you shall lodge with myself?'" To this proposal the other assented, delighted with the prospect of at once adding to his reputation and his knowledge.[Pg 224]

In Burmann's house he found a collection of natural objects and an extensive library, both of which were of great use to him. The time passed pleasantly enough, and he deferred his return to Sweden till the following spring; about which period, a circumstance occurred that proved of great advantage to him. Dr George Cliffort, burgomaster at Amsterdam and one of the directors of the Dutch East India Company, who was a zealous lover of natural science, was in need of a domestic physician to take daily care of his health. Boerhaave, who was his medical attendant, recommended Linnæus, whom he represented as being also an excellent botanist, and capable of arranging his botanic garden. Cliffort accordingly invited Burmann and Linnæus to Hartecamp, his villa, where they found many new plants from the Cape of Good Hope. The young Swede pointed out those which had not been described, and evinced so accurate a knowledge of botany, that the burgomaster made him a proposal of free board and lodging, with a salary of 1000 florins. The terms were accepted with no small satisfaction.

This year he published a tract which he had commenced at Upsal,—his Fundamenta Botanica,—in which he exhibited the basis of his new system in 365 aphorisms. About the same time he printed his Bibliotheca Botanica, another small work, the materials of which he had found in the libraries of Spreckelsen, Burmann, Gronovius, and Cliffort. A description of the banana-tree (Musa paradisiaca), which had flowered in the garden of his patron, formed the subject of a third treatise. The Imperial Academy of Naturalists at Vienna admitted him as a member, under the honourable appellation[Pg 225] of Dioscorides the Second, and his name began to be known throughout Germany.

Cliffort being desirous of extending his collection by obtaining new species from England, resolved to send Linnæus to that country, which he did in the latter part of July, limiting the period of his absence to twelve days. The passage from Rotterdam to Harwich occupied eight; and the stranger, finding himself surrounded by attractions, was in no haste to return, even to the elysium of Hartecamp. He arrived in London, with a letter of introduction from Boerhaave to the celebrated Sir Hans Sloane. Whether the venerable physician meant to make merry at the expense of the naturalists, or whether he really thought they both deserved the compliment which he paid to them in his note, let the reader determine:—"Linnæus, who will give you this letter, is alone worthy of seeing you, alone worthy of being seen by you. He who shall see you both together shall see a pair, whose like will scarcely be found in the world."

Notwithstanding this high encomium, Sir Hans exhibited no kindliness of feeling towards him. He was in fact a person who had grown old in self-esteem. Cliffort was desirous of procuring some plants from the garden at Chelsea, and his agent accordingly waited upon Mr Miller, who listened to his request with very little respect. At a subsequent visit, however, the Englishman became in some degree sensible of the merits of the young foreigner, and furnished him with the specimens which he had solicited. Proceeding to Oxford, he presented himself before the celebrated Dillenius, professor of botany, who received him much in the[Pg 226] same way as the others had done. "See," quoth Dillenius to his patron Sherard, who happened to be present at the interview, "this is the young man who confounds all botany." Although the Swede was ignorant of the language spoken by these islanders, he readily guessed at the meaning of "confounds," but thought it prudent to take no notice of the accusation. They then went to the garden, but the professor still treated the presumptuous youth with undisguised contempt. Next day, he waited upon Dillenius previous to his departure. "Before I go," said he, "I have one favour to request; tell me why you lately used those words about confounding botany." He refused to explain; but when Linnæus insisted that he should, "Come this way," said he; so the sheets of half of the Genera Plantarum were referred to. On almost every page were the letters N. B. When he asked what they meant, Dillenius said they marked the false genera. He maintained that the genera were not false, and the Oxonian referred to a plant in the garden, which he and other botanists considered as having three stamens. It was found to have only one, as his opponent had alleged. "O!" quoth Dillenius, "it may be so accidentally in a single flower;" but behold, all the flowers were the same; for when they examined a number, all turned out as the Swedish youth had described them. The professor had been slow of belief, it is true; but he now gave due honour to his visiter, detained him several days, and supplied him with all the plants which Cliffort required.

In a letter to his friend Dr Richardson, dated August 25, 1736, Dillenius expresses the following[Pg 227] opinion of him:—"A botanist is arisen in the North, who has founded a new method on the stamens and pistils, whose name is Linnæus. He has published Fundamenta Botanica, Bibliotheca Botanica, Systema Naturæ; and is now printing in Holland his Characteres, and his Flora Lapponica. He is a Swede, and has travelled over Lapland. He has a thorough insight and knowledge of botany, though I am afraid his method will not hold. He came hither, and stayed about eight days, but is now gone back to Sweden."
