line of the string, but not much, unless you 

 call that brain which runs clown into the hol- 

 low cavity of the spine, like a large whitish 

 cord, and which I have already told you is 

 called the spinal marrow. 



In the sides of the pile of bones called the 

 spine, are holes all along from top to bottom. 

 They are formed by notches in each vertebra, 

 which when put together form holes. There 

 are also six or seven pair of holes similar 

 to these, through the sides of the strong 

 bone below, on which the spine stands. 

 Through each of these run large branches of 

 the spinal marrow, called nerves. These 

 branches or cords are whitish, like the marrow 

 itself, and like the brain. Their number is 

 about thirty on each side. They part into 

 branches almost innumerable, and are distrib- 

 uted to nearly all parts of the body. Besides 

 these thirty pairs, nine pairs more go out from 

 the bottom of the brain itself, through holes in 

 the cranium. 



The nerves divide as minutely as do the 

 arteries and veins. This is proved by the fact 

 that we have feeling almost everywhere in us.
