 Moon by means of our equation (6). For this value of ^ we have 

 L = 1 when ?; = tt, so that the comparison can be made at once in 

 Table I. without any change of scale. A somewhat greater value of ^ 

 would perhaps better represent the observations, but this point does 

 not seem to reqixire close examination. In any case, the changed form 

 of the curve representing the successive values of L, as v increases,
