geminal bodies. Near the middle line on either side lies the fasciculus 

 longitudinalis posterior. From this point on to the quadrigeminal region 

 there are no important changes in the appearance of the cross-section of the 

 tegmentum. The fillet extends dorsally on the outer side. The brachia 

 retreat toward each other, and finally decussate higher up. 



The fibers of the crus, and those of the pons passing through it, have 

 been considered. It remains still to be said that in the superior levels of the 

 pons there is a system of fibers which becomes medullated shortly before 

 birth, rising out of the pontile fibers through the raphe, and then emitting 

 its fibers right and left in the substantia reticularis of the tegmentum. 

 According to Bechterew, these fibers end in the foremost part of the nucleus 

 reticularis. 



Ganglia, similar to those of the pons, are scattered on both sides of the 

 raphe, and in it as far upward as the tegmentum.
