stantly under the care of Dr. Civiale and experiencing relief by the 

 operation of lithotrity, where he died from a sudden attack of cho- 

 lera in September last. The Baron de Zach was a most zealous 

 friend to astronomy, and throughout his long life contributed to its 

 progress by his numerous publications, and by maintaining a most 

 extensive and laborious correspondence with the principal astrono- 

 mers in Europe. He was a man of warm and ardent affections, 

 rapid and sometimes hasty in his conclusions, of the most lively and 

 agreeable manners, and of the most indefatigable industry : and there 

 are few persons of the present day whose loss will be more sensibly 

 felt by the friends of astronomical science in every country in Eu- 

 rope. 



Barnaba Oriani, Director of the Observatory of the Brera at Milan, 

 where he has resided for fifty-five years as assistant and principal, 

 was born at Garegnano near Milan, in 1753. He was the principal 

 conductor of the measurement of an arc of the meridian in Italy, and 

 of the great trigonometrical survey of Lombardy, which took place 

 between the years 1786 and 1790; and throughout the course of a 

 long life, he devoted himself to the cultivation of physical and 

 practical astronomy. He was the first person who calculated the 

 orbit of the planet Ceres after its discovery by Piazzi at Palermo. 

 He published theories of the planets Uranus and Mercury, with 

 Tables of their motions. He laboured with singular skill and 

 perseverance in the improvement of the lunar Tables both by theory 

 and observation. He was the author of an admirable treatise on 

 spheroidical trigonometry : and the Astronomical Ephemeris of 

 Milan was published for many years under his directions, by Car- 

 lini. Upon the whole, if the union of practical with theoretical 

 science be considered, we shall be justified in pronouncing him to 

 have been, after Bessel, the most accomplished astronomer of the 

 present age. 



Antonio Scarpa, one of the eight Foreign Members of the Aca- 

 demie des Sciences of Paris, and probably the most profound 

 anatomist of the present age, was born in the year 1746, and died in 

 October last in his eighty-seventh year. He was made Professor 

 of Anatomy at Pavia in the twenty-second year of his age, and for 

 the last half-century he has been placed by the common consent of 

 his countrymen at the head of their anatomists and surgeons. He 

 was the author of magnificent and classical works on " The Organs of 

 Hearing and Smell," M On the Nerves," " On the principal Diseases 

 of the Eye," " On Aneurism," " On Hernia," with Memoirs on many 

 other subjects of physiology and practical surgery. He had ac- 

 cumulated a handsome fortune by the practice of his profession, 

 and had collected in his palace at Pavia a considerable number of 

 works of art, where he lived for the latter years of his life, sur- 

 rounded by his pupils, reverenced by his countrymen, and in the 

 enjoyment and contemplation of that brilliant reputation, the full 

 development of which a great man can rarely live to witness. 



In thus directing your attention, Gentlemen, to those distinguished 

 Members of the Royal Societv, who, unhappily for the interests of
