their social economy, their aptitude to successfully pro- 

 vide for or against unforeseen contingencies in which 

 instinct could hold only a minor part, their preparation 

 for probalde exigencies tliat could only be learned 

 inferentially led these great scientists to rank these 

 insects high in the intellectual scale. Yet, their ganglia 

 are poor apologies for brain. The smallest human 

 brain is said by Huxley to l)e fifty-five cubic inches 

 in volume ; the largest brain of the gorilla thirty- 

 five, and that of the orang and chimpanzee to be 

 twenty-six cubic inches in volume. These varied sizes 

 give no reliable data for measuring the mental ca- 

 pacity of each. We may fill up the hiatus be- 

 tween the difterent brains of each with an hypo- 

 thetical scale, and measure intelligence by it on 

 some common l)asis, but the attempt would show the 

 absurdity of the classification. Multifarious conditions, 

 as well as quantity of brain matter, must be taken into 

 account in measuring mind, and many of these being 

 still involved in obscurity, no definite results can be 

 obtained. A large brain in normal tone may exhibit 

 greater mental power, than a smaller one in the same 

 physical condition, just as a large magnet, or a cell bat- 

 tery in action increases magnetic strength in proportion 

 to size, not because of the inherent potential energy of 

 the instruments, Init because of the attributes they pos- 

 sess in manifesting the activity of the fluid. The l)rain 

 organ does not create and eliminate psychic force, ^;e/' se^ 

 but its structure, and constitution are such that in 

 tonicity it is the best medium to evolve the residuary 

 phenomena of the ego. The activity of this agent 

 sliows that in emotion, will, passion or desire electricity 

 and heat are the result of the energy ot" the tenant. 

 Time would fail to show that this has been fully proven 

 by experiments of the most conclusive kind. A])ply
