Missing pages

When I was reading Crawford-Gernsback's 1958 book (a pdf version) " Audio Measurements" and the chapter about "output transformer measurements", I discovered
some missing book pages: page 120 and 121. Apparently something went wrong during the copying process of this book.
Does somebody has a copy where those pages are not missing?
