To these we may add the following values, obtained from 

 the sulphates JFe-Li 1*27, JM-Li 1-19. iCo-Li 1-15, 

 iCu-Li 1-49, £A1-Li '6, ±Fe {

and the two following from the nitrates Ag — Li 3*91, and 

 iPb-Li4-51. 



The following Table contains the values of the parameter- 

 reciprocal moduluses of the different metals minus that for 

 Li and of the negative radicals minus that for CI.

It may be worth mentioning that these differences show a 

 pretty close parallelism to the corresponding differences of 

 the atomic refraction given by Gladstone (Phil. Trans. 1870) 

 but not close enough to be worth dwelling on. 



In the case of the organic bodies studied there was nothing- 

 analogous to this singular property possessed by these inorganic 

 compounds of having the reciprocal of the parameter A of 

 molecular force separable into a constant and definite parts
