The inner part of the brain is whitish-cream in colour, and is a 
vast mass of nerve fibres for the transmission of the commands of 
the grey cells to the various parts of the body. 
According to phrenology, there is a special centre in the brain 
for the manifestation of each of the great variety of thoughts, 
desires, and emotions, in addition to the nerve centres which 
control all movements, etc., of the body, and which carry out

the commands of the brain centres. These latter are called by 
phrenologists the Psychical Brain Centres. 
AN ELABORATE TELEPHONE SYSTEM. 
The grey matter of the brain is a great collection of groups of 
nerve cells, each group having a special function to perform in 
controlling and directing the vital functions, and the generation 
of thoughts, emotions and desires. From each group of grey 
cells, nerve fibres run out and are connected up with other 
brain groups and nerves running to the various parts of the 
body. 
The marrow or spinal cord enclosed in the backbone is the 
main cable from the brain. From this great cord, which can be 
compared to a telephone cable composed of great numbers of 
wires, nerves—just like telephone wires running out at intervals
