The expedition of Malaspina was also a factor of the movement, in the last third of the eighteenth century, to increase the world’s scientific knowledge of South America. This expedition would merit no special remark in this place but for the fact that Tadeo Haenke, one of its members, remained to be a permanent resident of Upper Peru, and became a contributor to the intellectual activity of that part of the continent. Haenke was born in Treibitz, Bohemia, near the Saxon frontier, on October 5, 1761. He studied at Prague, and was promoted to the degree of Doctor in 1782. Four years later he removed to Vienna, and continued his studies in mineralogy under Professor Ignacius Born and botany under Professor Nicolas Jacquin. His relation to these men was also that of a collaborator. Under the initiative of the latter he made a botanical exploration of the Alps. He was also charged with the preparation of the eighth edition of Linnæus’ _Genera plantarum_. [Sidenote: Haenke joins the expedition] At this time, 1788, the Spanish government was preparing the scientific expedition to be commanded by Malaspina, and asked Professors Born and Jacquin to designate a person who might join the expedition in the capacity of naturalist. Without hesitation they nominated Tadeo Haenke, who, although only twenty-seven years old, had already given evidence of remarkable knowledge and ability. Their suggestion was accepted, and Haenke entered upon the journey from Vienna to Cadiz; but by a miscalculation of the time required for it, and by delays in Paris and Madrid, he arrived at the port shortly after the “Descubierta” and the “Atrevida” had sailed. He followed by the first merchant ship available. This was wrecked at the mouth of the Río de la Plata, and through this misfortune Haenke lost most of his books, papers and instruments. He arrived at Montevideo eight days after Malaspina had departed for the Strait and the Pacific. Aided by the government of Buenos Aires, Haenke now undertook the overland journey across the pampas and over the Andes. When he arrived at Santiago, April 10, 1790, Malaspina’s ships had already anchored at Valparaiso.
