The references are, in all cases, to pages. Numbers referring to pages upon which the

 cluded in this Index; for fuller descriptions consult the pages cited. Terms which are 

 defined in this Glossary are printed in black-faced type. The names of fiber tracts, in 

 general, define their connections, the first part of the compound word indicating the 

 nucleus of origin and the last part the terminal nucleus (see page 128). To facilitate 

 cross-reference, the key-word of a polynomial term is capitalized wherever it occurs in this
