Taking the data of Table I., I have computed the vakies of the inter- 

 ferential constant /for at least three dilFerent temperatuiies in the case 

 of each liquid. Five determinations are given in the case of water, 

 and four in the case of cai'bonic disulphide. As the density of water, 

 even for a limited range of temperature, cannot be expressed by a 

 linear function, I have computed it from the volumes as given by 

 Pierre. My general results are given in Table II.
