official duties, and perhaps also his advancing years, restricted some- 

 what his contributions to the American Association. In 1881 he 

 presented papers to the Association at its Cincinnati meeting ; in 

 1882 he was President of Section I., and delivered an address upon 

 Economic Science and Statistics ; and in 1886 he made the last of 

 his many contributions, at the Buffalo meeting, in a paper dealing 

 with the rate of interest realized to investors in government securi- 

 ties, and offering formulas for determining the United States gold 

 value of silver bullion, when the London price per ounce of standard 

 silver and the price of Sterling Exchange between New York and 

 London are known. 



His last scientific work was in connection with the Metrological 

 Society, in 1887. The second volume of the Proceedings of that 

 Society contains several communications from bis pen. 



Mr. Elliott reached the close of his busy and useful life, at Washing- 

 ton, on May 24, 1888, in his sixty-third year. He was never married. 



This brief review of his numerous and varied works fully justifies 

 the conclusion that he was among the most meritorious of American 

 statisticians and actuaries. Personally, Mr. Elliott was one of the 

 most amiable of men, with a childlike simplicity of character and 

 utterly incapable of offence or of guile.

MICHEL EUGENE CHEVREUL. 



Michel Eugene Chevreul died in Paris, April 9, 1889. He 

 was born at Angers, on a branch of the Loire, August 31, 1786. 

 The mere fact that any one prominent in the world of science should 

 have lived to the extraordinary age of almost one hundred and three 

 years is in itself so surprising and unprecedented that our thoughts 

 tend to dwell upon it unduly. A moment's reflection is needed to 

 bring into clear light the deeds of merit which made the man 

 illustrious. It is to be remembered that Chevreul was the contem- 

 porary of chemists who died when most of us here present were 

 children or not yet born. The friends of his youth were Amprre 

 and Gay-Lussac, D'Arcet, Davy, Oersted, Wollaston, and Berzelius. 

 Proust was his townsman, Vauquelin was his teacher, and it is evi- 

 dent that Fourcroy also had no little influence upon his scientific life.
