We said that what we described as “numeral equality”, “being 1-1 correlated”, “having the number n” were widely differing phenomena. That therefore it was an ilusion to think that to say “the classes fall in pairs” is, generally speaking an analysis of what we call numeric equality in simpler terms. We can if we like put “being numerically equal” = “falling into pairs” but the use of the one expression just as of the other has got to be explained in the particular case. This we only forgett. Thinking about a very special class of examples.

The idea is that if they ha[b|v]e the right existential structure they do fall into cou[l|p]les & this is demonstrated. The question how we find out in the special case that they do have the right s[p|t]ructures is neglected.
One could also say that a length a was twice another one b if the two a superimposed gave b. Application for wavelengths.
This brings me to the topic of

demonstration.
1)

N^r. of outer vert = N^r of inner vert 5.

   Compare with “the Hand has 5 Fingers.”
  Timelessness. The save hold of “The number of outer vert. = N^r of inner vert”
    Question which is answered by this prop timeless. ˇApparent Generality of demonstr.
    The copula has no tenses.
  ◇◇◇ idea is that the idea of a pentagram is bound up with a cardinal N^r. Now, we could make all sorts of connections.

“It is the essence of these figures to be capable of being

connected
devided

in this way”.
