652 SCIENTIFIC RECORD FOR 1883. 



the formula CnH n N. The same chemist describes cenantholaniliu, 

 cenantholxylidin, and cenantholnaphtylamin, bodies having agreeable 

 etherial odors, and yield amorphous sublimates with partial -decompo- 

 sition. — (Ber. d. c'hem. Ges., xvi, 287 and 289.) 



Silicon-ethers of phenol, according to A. Martini and A. Weber, are 

 easily prepared by heating the phenols with silicium tetrachloride. 

 Tetraphenyl silicate and tetraparakresylsilicate are described by them. 

 (Ber. d. chem. Ges., xvi, 1252.) 



The Liebig memorial was unveiled at Munich, August 6, 1883. 

 Prof. A. W. Hofmann made the principal address on the occasion, re- 

 viewing the influence of Liebig's discoveries in chemistry. A few 

 months after the ceremony, the white marble statue of Liebig was 

 wantonly injured by some black liquid which was thrown over the head 

 and left shoulder. It was feared that the statue was permanently in- 

 jured, for the black substance had penetrated the pores of the marble. 

 Later advices show that the liquid used was nitrate of silver. One 

 thousand marks reward were offered for the perpetrator. In December 

 the stains were successfully removed. 



Frederick Wohler is fitly honored in the Berichte der deutschen chemi- 

 schen Gesellschaft by a long biography and bibliography prepared by 

 Prof. A. W. Hofmann. Wohler's contributions to chemical literature 

 number 280. The paper is accompanied by a portrait and a fac-simile 

 letter. 



Honors to an American chemist' — The German Chemical Society of 

 Berlin has on its rolls the following sixteen honorary members, repre- 

 senting, as will be seen, a variety of nationalities : E. Bunsen of Hei- 

 delberg, J. Dumas of Paris, H. Kopp of Heidelberg, S. Cannizzaro of 

 Pome, E. Frankland of England, E. Fresenius of Wiesbaden, J. S. Stas 

 of Brussels, A. Williamson of London, A. Wurtz of Paris, G. Kirchhoff 

 of Berlin, H. E. Eoscoe of Manchester, C. von Marignac of Geneva, F. 

 Abel of Woolwich, A. Butlerow of St. Petersburg, Warren de la Eue 

 of London, and Q. Sella of Borne. The society in 1883 honored itself 

 and recognized the claims of the United States by adding to this dis- 

 tinguished company Dr. Wolcott Gibbs, professor of chemistry in Har- 

 vard University, who confessedly stands in the foremost rank of scien- 

 tific investigators.
