354 Analysis of Scientific Books and Memoirs. 



And here we must mention one individual, Nic. Jos. Baron vonJacquin, 

 who flourished both during the time of Linnaeus, and long after; and 

 who thus, beginning his career while systematic botany was yet in its infan- 

 cy, or indeed scarcely known, lived to see it fixed upon a firm and solid ba- 

 sis, whilst he himself aided materially in its establishment. He was born 

 at Leyden, and studied at Antwerp, Louvaine, Rouen, and Paris. Along 

 with Gronoviux, he received instruction in botany under Adrian von Royen. 

 At the invitation of Van Swieten, physician to the empress, he was invit- 

 ed to go to Vienna, where he became a physician, and gave lectures on 

 Hippocrates, devoting his leisure time to botanizing around the city, and 

 to visiting the newly formed Imperial Garden of Schoenbrun. 



It was here the Emperor Francis I. became acquainted with him, and 

 loved and esteemed him, as every one else did who had the happiness of 

 his acquaintance. He received orders to draw up a catalogue of the plants 

 of the Schoenbrun Garden, according to the method of Linnaeus, which 

 he was thus the means of introducing to Vienna. This, too, he did so 

 satisfactorily, that he was directed to make a voyage to the West Indies, 

 along with the gardener Schott, in order to collect plants and animals 

 from that part of the New World. He returned to Vienna in 1739, and 

 wrote his " Historia Stirpium Americannm." In 1763, the Empress Maria 

 Theresa appointed him counsellor of the mines, and professor of chemistry 

 and mineralogy at Schemnitz. In 1768, he became professor of botany 

 and chemistry at the University of Vienna in the room of Languier ; and 

 in every department to which he was called, he showed himself to be most 

 profound, both as a man of science and a scholar. He now published his 

 Hortus VindoLonensis, 3 vols, in folio ; " Flora Austriaca," 5 vols, in folio, 

 and his " Miscellanea Austriaca" and "Collectanea." 



Leopold II. confided to him the direction of the famous garden of Schoen- 

 brun ; where, finding that he had leisure for such publications, he edited, 

 under the auspices of the emperor, the splendid and justly celebrated 

 works, tf Hortus Schoenbrunensis," " Icones Plantarum rarioru/n." *' Mono- 

 graphia Oxalidum," &c. Towards the close of his life, he gave an account 

 of the parts of fructification of the Asclepiadea, and was much occupied 

 with the Stapelia;, of which singular family of plants he published a his- 

 tory in a folio volume, between the years 1806 and 1S15, this being the last 

 of his works. Indeed, so much was he interested in these vegetables, that in 

 his dying illness, after having for many days lain without speaking, and 

 without motion, he inquired one fine morning in August, " if there were 

 any Staptlias in flower." 



The mortal career of this excellent man was closed in 1818, at the age 

 of ninety years and eight months, at his house within the garden of Schoen- 

 brun : where, for some time past, he had constantly resided, amidst a vege- 



Street But Scopoli, probably from his ignorance of the English language, had the 

 impression that Mr Horace Head was a partner in the firm, and, therefore, determin- 

 ed to dedicate the plate to the two individuals jointly. The artist indeed added to 

 the blunder, and inscribed upon the copper-plate " AnspieUx Bcnjamini White el 

 Horatii Head, Bibliopnl. LcimUnensium."
