VI. Summary of Results. 



I. In the absorption spectrum of non-luminous mercury vapour 

 there has been shown to be a strong symmetrically spaced band at 

 A = 1849-6 A°.U., a diffuse complex band at A = 2338 A°.U., and an 

 asymmetrical band at A = 2536 -72 A°.U. The complex band at A = 

 2338 A°.U. consists of a band extending from A = 2313 A°.U. to A = 

 2320 A°.U. one at A = 2322 A°.U. another at A = 2326 A°.U. and a 

 wider one between A = 2330 A°.U. and A = 2338 A°.U.
