PHYSICS. — Wave lengths of Neon. Irwin G. Priest. Com- 

 municated by S. W. Stratton. To appear in the Bulletin of 

 the Bureau of Standards, 8: No. 4. 1912. 



Ten wave-lengths in the spectrum of neon have been deter- 

 mined by the method of flexure with reflection fringes previously 

 described. 1 



The following values result from a long series of determinations. 



The probable errors are in every case less than one part in 

 10,000,000. Confirmatory results and counter checks indicate that 

 the values given are accurate within about one or two thousandths 



c 



of an Angstrom unit. A detailed discussion of the accuracy will 

 appear in the complete paper.
