The isothermal layer of the atmosphere and atmospheric radiation, E. 

 Gold {Proc. Roy. Sac. [London\, Srr. A, 82 {1909), Xo. A55t, pp. .',3-70). —The 

 topics treated in this article are the phenomenon of the isothermal layer and 

 the experimental evidence of its existence ; the possible temperature distribu- 

 tions in an atmosphere; experimental data on gaseous radiation and absorp- 

 tion ; and general expressions for the radiation from the atmosphere and con- 

 ditions of its e(piilibrium as ai)plied to an atmosphere of uniform constitution, 

 the earth's atmosphere, taking into account the diminution of water vapor 

 with height, and the day and night temperatures of the earth's surface.
