1 The ionization coefficients used in calculating the depressions of this series 
were based on the first series of observations on hydrochloric acid solutions, because 
these observations were made on the solutions actually mixed with the sodium 
chloride solutions, and were made by Mr. Barnes at the same stage of his 
perience with observations of this kind.
