 have been previously noticed. 



Pt. colli dorsalis. — This is a broad tract, not closely

 support for the tract. Thus, in section, the tract is T-shaped. 



PL spinalis. — This tract forms a tolerably broad band 

 along the middle of the back, expanding over the pre-iliac 

 region into an ovoid saddle, which, just caudad of the
