736 Dr. Tycho E:son Auren on Scattering and 



when examining a water solution of one salt of the metal 

 in question and from the direct examination of the solid 

 metal. 



In the following table are noted the observed values of 

 ^a/h 2 o obtained, when examining a number of organic 

 substances. In each column is shown the observed value for 

 the effective wave-length stated in Table I., and beneath the 

 value calculated by means of the values for /c H/Ho o, *"c/h 2 o, and 

 ^o,;h 2 o derived from the observations (Table III.). Moreover 

 the table includes the observed values for /£a/h 2 o £° r N 2 H 4 in 

 waterfree solution (produced out of hydrazine hydrate from 

 Kahlbaum) .
