Ochsenheimer was seized with an attack of apoplexy, 

 and died in 1822. His collection was purchased for the 

 Royal Museum at Pesth. 



OLIVIER, Dr. Guillaume Antoine, born in 1756, a French 

 naturalist and traveller, whose especial studies were 

 Botany and Entomology, was employed in early life in 

 describing and collecting particulars about the natural 

 objects and productions of the neighbourhood of Paris. 

 Losing this post at the Revolution, but siding with the 

 Revolutionary Party, he and Bruguiere were appointed 

 in 1792 by the minister Roland to accompany the em- 

 bassy to Persia, as scientific attaches. Roland perished, 

 and the scientific men were deprived of their resources ; 

 nevertheless they pursued their journey, visited Con- 

 stantinople, the Isles of the Archipelago, Syria, Egypt, 

 Arabia, and finally Bagdad, Teheran, and Ispahan. 

 Having obtained favourable answers from the Persians 

 on the objects of their mission, they returned up the 

 Euphrates to Aleppo, visited Cyprus, traversed Asia 

 Minor to Constantinople, thence to Greece, and finally 

 landed at Ancona in September 1 798. There Bruguiere 

 died ; and Olivier returned alone to Paris, with a valuable 

 collection, the result of their six years' ramble. He im- 

 mediately occupied himself with the production of his 

 " Voyage dans PEmpire Ottoman, PEgypte, et la Perse " 

 (Paris, 6 vols., 1802-7). In 1800 he was chosen Mem. de 

 PInstitut, was subsequently Professor of Zoology at the 

 Ecole Veterinaire d'Alfort, but for some time before his 

 death became afflicted with melancholy. He died at 

 Lyons, in 1814. Besides his " Travels," Olivier was the 

 author of articles on Insects in the Encycl. Methodique, 

 and of the "Dict.de PHistoire Nat. des Insectes" (9 vols.) ; 

 he also published ' ' Entomologie, ou THist. Nat. des 

 Insectes" (6 vols.). His great work, however, is " Hist. 

 Nat. des Coleopteres " (also in 6 vols.), in which an im- 

 mense number of species of beetles were for the first time 

 figured. 



PALLAS, Peter Simon, born in 1741, was the son of a surgeon 

 at Berlin. After studying at Berlin, Gottingen, and 

 Leyden, he spent a year in England, and in 1763 settled 

 at the Hague, where he published " Elenchus Zoophy- 

 torum," and " Miscellanea Zoologica" (1766). In 1767 

 he was invited to St. Petersburg by the Empress Catha- 

 rine, and accepted the post of Professor of Natural

 Pallas set out on a scientific mission, travelled through
