gravity of 9.2. The original thorium gave atomic 

 weights 232.5 to 232.6, and its oxide had a specific 

 gravity of 10.5. The original thorium dioxide phos- 

 phoresces under the influence of ultra violet light, as 

 does zirconium dioxide. Berzelium and carolinium 

 oxides do not respond to this stimulus, while the 

 new thorium glows with increasing luminosity 

 according to the decrease of the novel substances. 

 All these bodies are radio active. Certain chemical 

 differences are noted, as, for example, the conduct of 

 their salts with organic bases, fumaric acid, &c. 

 Carolinium oxide is soluble in concentrated hydro- 

 chlroric acid, while berzelium and carolinium oxides 

 are not. Spectral data are wanting; in fact, the 

 limited portions of the spectra (arc and spark) 

 mapped show the bodies identical. The materials 

 are not yet sufficiently pure, nor the spectral data 

 sufficiently complete, to warrant final acceptance, 

 although the preponderance of evidence is favorable 

 to the assumption of the existence of two new 

 members of the family of chemical elements. * 



business meeting. 



The Academy was called to order at 12:30 P. M. "by 

 President Baskerville. 



Prof. Poteat urged a continuance of a joint meeting of the 

 Academy with the Chemical Section, and presented the 

 following resolution: 



"That the Academy reaffirm its desire that the scientific 

 societies and clubs of the State should hold each one session a 

 year in connection with the annual session of the Academy." 

 Carried. 



Secretary reported the election to membership of Messrs 

 William B. Streeter and W. C. A. Hamniel, of Greensboro. 



On recommendation of the Nominating Committee the 

 following officers were elected for the ensuing year: 



President, F. L, Stevens, Raleigh. 



Vice-President, Jno. F. Lanneau, Wake Forest. 



Secretary -Treasurer, Franklin Sherman, Jr., Raleigh.
