more or less explained by this theory: some of the phenomena of 

 thermal chemistry and some phenomena connected with contraction of 

 bulk in combining- elements. 1 am not sure but the matter of attrac- 

 tion, of gravitation will ultimately be found related to this hypothesis. 



Finally, while analogies — correspondences in nature in various de- 

 partments — require to be carefully handled, if we would adhere to stricdy 

 scientific methods; nevertheless the appeal to analogies may be useful in 

 illustrating and corroborating inductions already drawn from facts in 

 other fields. Now, what, in fact, is the foundation and "cause" of 

 affinities and attractions among human beings and the lower animals?' 

 Compatability and accordance of movements! That is to say, conduct 

 on the part of two or more individuals which will harmonize and fit 

 together. The tendency of all of us lo move in lines of least resistance 

 causes us to be attracted towards those who are in sympathy with us, 

 and whose movements are therefore synchronous and of like form to, 

 and harmonize with ours, instead of being obstructive. It was forbidden 

 by a wise law giver to yoke the ox and the ass together, and why ? 

 Because their movements in walking and pulling are totally unconform- 

 able, inconsistent, and will not combine; they are heteromorphous as 

 well as unsynchronous, and therefore destructive to each other's 

 efficiency.
