For it is an unquestionable fact that in first presenting a classification of the animal kingdom based upon a knowledge of its structure, Blumenbach in a measure anticipated Cuvier; though it is only by an exaggeration of what Blumenbach did that an unfair writer of later times has attempted to deprive Cuvier of the glory of having accomplished this object upon the broadest possible basis. From Goettingen he visited the Rhine, for the purpose of studying geology, and in particular the basaltic formations of the Seven Mountains. At Mayence he became acquainted with George Forster, who proposed to accompany him on a journey to England. You may imagine what impression the conversation of that active, impetuous and powerful man had upon the youthful Humboldt. They went to Belgium and Holland, and thence to England, where Forster introduced him to Sir Joseph Banks. Thus the companions of Captain Cook in his first and second voyages round the world, who were already venerable in years and eminent promoters of physical science not yet established in the popular favor, were the early guides of Humboldt in his aspirations for scientific distinction. Yet Humboldt had a worldly career to accomplish. He was to be a statesman, and this required that he should go to the Academy of Commerce at Hamburg. He remained there five months, but could endure it no longer, and he begged so hard that his mother allowed him to go to Freyberg and study geology with Werner, with a view of obtaining a situation in the Administration of Mines. See what combinations of circumstances prepare him for his great career, as no other young man ever was prepared. At Freyberg he received the private instruction of Werner, the founder of modern geology, and he had as his fellow-student no less a man than Leopold Von Buch, then a youth, to whom, at a later period, Humboldt himself dedicated one of his works, inscribing it "to the greatest geologist," as he was till the day of his recent death. From Freyberg he made frequent excursions into the Hartz and Fichtelgeberg and surrounding regions, and these excursions ended in the publication of a small work upon the subterranean flora of Freyberg ("Flora Subterranea Fribergensis"), in which he described especially those cryptogamous plants, or singular low and imperfect formations which occur in the deep mines. But here ends his period of pupilage. In 1792 he was appointed an officer of the mines (Oberbergmeister). He went to Beyreuth as director of the operations in those mines belonging to the Frankish provinces of Prussia. Yet he was always wandering in every direction, seeking for information and new subjects of study. He visited Vienna, and there heard of the discoveries of Galvani, with which he made himself familiar; went to Italy and Switzerland, where he became acquainted with the then celebrated Professors Jurine and Pictet, and with the illustrious Scarpa. He also went to Jena, formed an intimate
