The first of his correspondents of whom we shall make mention is the celebrated Albert Haller, who was born in October 1708, and died on the 12th December 1777, aged 69. He was eminently distinguished for his knowledge of the physical sciences, as well as by his poetical talents, and his general acquaintance with literature. In fact, he aimed at universal dominion; and the renown of Rousseau, Voltaire, Linnaeus, and Buffon, excited his envy of some and his contempt of others of these celebrated men. After the death of his father, who was an advocate and citizen of Berne, he chose the medical profession; and in 1723, went to Tubingen, where he studied comparative anatomy under Duvernoi. In 1725, he removed to Leyden, then the first medical school in Europe. After taking his degree at the former seminary, he visited England, whence he went to Paris, and dissected under Le Dran. He then proceeded to Basil, to study mathematics under Bernouilli. There he imbibed also a taste for botany,--a science in which he subsequently made great progress. In 1729, he returned to Berne, and commenced his professional career as a lecturer on anatomy. In 1736, he was appointed by George II. to the professorship of surgery and botany in the University of Gottingen. Here he resided seventeen years, in the course of which he distinguished himself by his numerous and important discoveries. But, in 1753, having taken a journey to Berne, where his countrymen received him with the honour due to his talents, he settled there, and, having been elected a magistrate, entered with zeal on the duties of a citizen. The correspondence of Linnaeus with this eminent naturalist and physician commenced when the latter was at Gottingen, and originated in a report that he was hostile to the proposed system of the young Swede, who thus supplicates his forbearance:-- "_From Mr Cliffort's Museum, April 3, 1737._ "... 1. I must declare, that I am anxious to avoid, if possible, all anger or controversy with you; my wish is rather to act in conjunction with you. I should detest being your adversary, and, as far as possible, I will avoid it. May there be peace in our days! "2. I have always, from the time I first heard your name, held you in the highest estimation; nor am I conscious of ever having shown a contrary disposition. Why then should you provoke me to a dispute? Let me know if I have unwillingly offended, and I will omit nothing to satisfy you. I ask but for peace.
