is this correct?? [Gardner Read]

From Gardner Read's _20th Century Microtonal Notation_ page 113:

"A mean-tone fifth is one-fourth of a syntonic comma (21.5c) smaller
than a well-tempered fifth (697c to 702c, a difference of 5c)."

Isn't 702c a "just" or "Pythagorean" fifth?? Is it considered
a "well-tempered" fifth as well??

Help!

Thanks!

yes.

it can occur in well-temperaments, but these well-temperaments would
need to have other, smaller fifths as well -- since the circle needs
to close after 12 fifths, the *average* size of fifth in a well-
temperament equals 700 cents.

***That's exactly what I thought... so that sentence is pretty
ambiguous... Oh well, the book is quite good in other ways, though...
