The problem is that to get a readable scan the circular would have to
be unbound (if there is such a word) in order to get them flat in the
scanner. Secondly, the original edition is 1924 with a reprint in
1937. The reprint has "certain type corrections and omissions". I
have no idea if the page numbering is the same. I mention this
because if you find a copy, your only recourse may be to retype the pages.
Libraries are a bit fussy about cutting books apart....even paper
backs like this. Good luck

Essentially correct except the original printing was in 1918,
during WW1. It was a compendium by a young man named George
Southworth, on his first job out of school. He later went on to
spend many years in the radio business and did a great deal of early
work on waveguides (including some submerged in a swimming pool to
effectively make them larger) and microwave horns. I wouldn't be
surprised if he built TC's as a kid, but he doesn't mention that in
his book "50 YEARS OF RADIO ENGINEERING".
