sufficiently great, a definite value of the abso rption co- 

 efficient for a fixed wave-length (683 /jl/jl) can be taken 

 as representing a definite stage of the coalescence. 



In the following tables the absorption coefficients at 

 different times are given for the wave-length 683 fi/ju. 

 The tables are taken from the paper by Mukherjee and 

 Papaconstantinou, loc. cit.
