4 o8 THE POPULAR SCIENCE MONTHLY. 



The atmosphere of a large city is not conducive to much origi- 

 nal work in science, and especially is this the case in New York 

 city. Things of a more practical nature force themselves upon 

 the attention of a scientist, and his opinion is in constant demand. 

 In consequence, we find in the American Contributions to Chem- 

 istry but two papers devoted to original research contributed by 

 Prof. Joy during the time of his connection with Columbia Col- 

 lege. They are On Glucinum and its Compounds (1863), and 

 Analysis of a Meteorite from Chili (1864), both of which were 

 published in the American Journal of Science. Several of the 

 analyses of minerals that appeared in Dana's System of Miner- 

 alogy by him were also made at this time. This meager record is 

 readily explained by the fact that Prof. Joy's literary inclination 

 was promptly taken advantage of by the editors of prominent 

 periodicals, and articles from his skillful pen were constantly in 

 demand. He was a frequent contributor to the Scientific Ameri- 

 can, and every week prepared columns of notes for Frank Leslie's 

 periodicals, reviewing all of their foreign scientific exchanges for 

 them. For many years he edited the Journal of Applied Chem- 

 istry, published in New York, and also wrote most of the articles 

 on chemistry in Appletons' American Cyclopaedia. 



Prof. Joy was naturally prominent in numerous organizations, 

 chiefly, however, in those of a scientific character. He held the 

 chairmanship of the Polytechnic Association of the American In- 

 stitute; he was also President of the American Photographic 

 Society. During 1866-'67 he was President of the Lyceum of 

 Natural History, now the Academy of Science, from which place 

 he gracefully and generously retired after a brief service in order 

 to afford an opportunity to Dr. John S. Newberry to be introduced 

 to the scientific circles of the metropolis. In 1874, when the 

 American chemists gathered at the grave of Priestley, in North- 

 umberland, Pa., and an organization was effected to celebrate the 

 Centennial of Chemistry, Prof. Joy was chosen one of the vice- 

 presidents. He was a Fellow of the American Association for the 

 Advancement of Science, and for a time was Foreign Secretary of 

 the American Geographical Society ; he was likewise an enthu- 

 siastic member of the Century Association. It is but fair also to 

 record his active interest in various charitable societies, and he 

 was a member of the Protestant Episcopal Church. 



Among the many interesting experiences of his life none per- 

 haps gave him more delight than his connections with the various 

 World's Fairs. He served on juries of those held in London, Paris, 

 Vienna, and Philadelphia. During the terrible heat in 1876, 

 while actively engaged in his duties at the Centennial Fair 

 in Philadelphia, he was prostrated by sunstroke. He was 

 promptly brought to his city home, but a cruel illness of many
