It is important to note that we were able to investigate the conductivity of salt 

 vapours at much greater concentrations in the flume than was done hy AKUIKMI - 

 and. as will appear in what follows, the results at high concentrations are very 

 different from those obtained at the lower ones.

* This estimate, which has no pretensions to exactness, was made chiefly in order to inform us how our 

 experiments compared with those of AKKIIKMI s in respect to the concentration of *dt in the flame. In 

 his experiments a normal solution sent into the flame '26 x 10"* gram molecule of salt per minute. In 

 our apparatus an ,' normal solution would yield this amount of salt. Wo confirmed this result hy com- 

 "t the conductivity immltcrs for salt solutions.
