brain. In producing a galvanic current it is known that the 
principal irritating sensation does not result from the positive or 
efflux pole, but at the negative, and where the forces strike after 
completing or nearly completing the circuit. Hence, if the sen¬ 
sor currents should stop at the brain or the gray matter, it 
would be felt there and not at the starting point. In such a 
case terrible and dangerous wounds may be inflicted upon human 
subjects or animals, and we should not and would not know by 
feeling or sense of feeling where to locate them. If we should 
take the effect of the nerve forces to the spine and not to the 
brain we should have unconscious sensation or at least a very 
indefinite effect of it. 
5. The Functions of the Special Senses of Sight, Touch , Hear¬ 
ing, Taste and Smelling all excited by the aid of thermal and 
electrical currents of the animal organism working simply in har¬ 
mony with chemical law. The most refined of these, the sinht

is acted on by ethers only; hearing, the next, is produced by 
means of ethers and atmospheric gases. Smell deals mainly with 
gases ; taste with liquids or semi-solids and touch, last of all, 
with solids, liquids, gases and ethers. (This shows a coarser 
grade as seen in atomic principles in electro-physics of modern 
date). 
The organ of sight deals with luminous ethers in the form of 
liquid and colors, through the medium of which everything in 
the universe is revealed to man. Scientists have shown us that 
the retina contains thermal elements which attract by the same 
law and receive chemically the electric colors of light and also 
contains electrical elements which receive and appropriate the 
thermal rays of light. Hence the blue elements in the retina 
receive the red rays ; the red elements receive the blue rays ; 
the violet elements receive the yellow rays, and so on; in this 
way these luminous ethers send their impressions upon the brain 
proper which produces the wonderful phenomena of vision. 
Herr Salzer estimated in an essay before the Vienna Academy 
of Sciences several years ago that there are 438,000 nerve fibres 
and 3,360,000 retinal rods and cones in the human eye.
