An hour was given on Saturday morning 

 to a joint meeting with the Society for the 

 Promotion of Agricultural Science when the 

 papers presented before this Society on en- 

 tomological subjects were read. 



By the courtesy of the Gypsy Moth Com- 

 mission of the State Board of Agriculture, 

 Massachusetts, an excursion was given to 

 the members of the Association to the dis- 

 tricts about Maiden where work is being 

 prosecuted against the gypsy moth, oppor- 

 tunity being afforded the members to make 

 an examination of the methods of work fol- 

 lowed and the results obtained. 



The following officers were elected for the 

 ensuing year: President, C. L. Marlatt; 

 First Vice-President, Lawrence Bruner ; 

 Second Vice-President, C. P. Gillette, and 

 Secretary- Treasurer, A. H. Kirkland. 



In accordance with the established custom 

 the next session will be held on the two 

 week days preceding the general sessions 

 of the American Association for the Ad- 

 vancement of Science, and at the place se- 

 lected by the latter body. 



C. L. Marlatt, 



Secretary. 



NOTES ON INORGANIC CHEMISTRY. 

 In a paper read before the Chemical Sec- 

 tion of the British Association at the Bristol 

 meeting Professor Eamsay describes more 

 fully the isolation and properties of the new 

 element neon. Eighteen liters of argon 

 were liquefied and then fractionally dis- 

 tilled. After three fractionations the 

 lightest fraction had a density of 9.76. This 

 gas no longer liquefies at the temperature of 

 liquid air boiling at 10 mm. and consists 

 chiefly of neon with the admixture of small 

 quantities of argon and nitrogen. Pure 

 neon seems to have a density of 9.6, and, as 

 the ratio between specific heat at constant 

 pressure and constant volume is 1.655, the 

 element is, like helium and argon, mon- 

 atomic, and its atomic weight therefore 19,2,
