In this part of the table it can be seen that the second 

 values of MH are about 1*2 times the first, which is again 

 confirmatory of the general fitpess of our equations to give 

 relative values of M. 2 l. There are a number of irregularities 

 in the data of Table III., especially in connexion with the 

 values of M//o for molecules containing more than two atoms 

 of halogen : the differences in M//o for Br 3 and Cl 3 , and for I 3 

 and Cl 3 are far from constant and far from three times the 

 difference for Br and Gl, and I and CI : a special study of the 

 molecular domains of several of these compounds ought to 

 be made. As to the laws reigning amongst the values of M 2 /, 

 they are specially discussed in a manuscript paper entitled 

 " Further Studies on Molecular Force/' which I hope will be 

 published about the same time as this present paper : it is
