The following pages are broadly corollary to others published 
in the effort to establish the mental phenomena registered by 
thought-connectives , 1 by strictly pronominal words 2 and by 
words improperly ranked as such, especially relatives 2 and in- 
terrogatives . 3 
They sketch the further application of an assumption de¬ 
veloped in those former publications—the assumption that in 
various ways a factor of one thought may also be a factor of 
another thought.
