In 1736, Linnæus made a tour to England at the expense of Mr. Clifford, who wished him to inspect the gardens of our country, and to communicate with the eminent botanists then alive. The English professors were warmly attached to the system of Ray; but Dillenius, the botanical professor at Oxford, was so impressed with the talents of Linnæus, that he urged him to take up his residence there, offering to share the profits of his professorship with him. Professor Martyn of Cambridge, Miller, Collinson, &c., held friendly intercourse with him, and he returned to Holland with the most favourable impressions of the scientific men in England. Contrary to the wishes of Mr. Clifford, he left Hartecamp towards the close of 1737, with the intention of returning to Sweden. No stronger proof can be given of the estimation in which Linnæus was held in Holland than the regard expressed for him by Boërhaave, even on his death-bed. Before the time of Linnæus’ intended departure from Leyden, Boërhaave became too ill to admit visitors. Linnæus was the only person in whose favour an exception was made, that the dying physician might bid him an affectionate farewell. “I have lived,” he said, “my time out, and my days are at an end; I have done every thing that was in my power: May God protect thee! What the world required of me it has got; but from thee it expects much more. Farewell, my dear Linnæus!” When upon the point of leaving Leyden, Linnæus was attacked by illness; and upon his recovery he determined to visit Paris before his return to Sweden. At Paris he experienced great kindness from the Jussieus; and he received the high compliment of being elected a corresponding member of the Academy of Sciences. In the summer of 1738, he embarked at Rouen for Helsingburg. Soon after his arrival in Sweden, he married the lady to whom he had been so long attached. Dr. Pulteney, in his “View of the Writings of Linnæus,” gives a full account of the numerous publications put forth by him during his residence in Holland, and adds,—“It is scarcely to be conceived how this great man found time to finish so many works, any one of which would have been sufficient for establishing his character as a botanist.” The most important of these were the “Systema Naturæ,” 1735, and the “Genera Plantarum,” 1737, in which the sexual system of plants is fully developed. In 1738 Linnæus settled as a physician at Stockholm, where he met with so much opposition, that he almost resolved to quit his native country. But by perseverance he worked his way into practice; and he was fortunate enough to be employed by the Queen of Sweden. In 1739 he contributed, with some other spirited persons, to form an Academy at Stockholm, of which he was elected President.
