I acquired the following scans of a couple of pages of "Studies In the Scriptures" Vol 3 "Thy Kingdom come"
See what he makes of The Great Pyramid
Opposite page 332 is the following chart, printed sideways
You can see the same chart in http://en.wikipedia.org/wiki/Charles_Piazzi_Smyth
It seems to me, although it was not attributed to anybody else on the page of the book, it is the work of Charles Piazzi Smyth.The Wikipedia article makes interesting reading.
I have also a scan of pages 362 & 363
This gives some prophecy and measurements within the pyramid. It is interesting that the measurements are not in standard linear measurement. They used something called "pyramid inches". This was apparently invented by C P Smyth and was equal to 1.001 inches. A small difference but significant over the long lengths measured.
Imagine: If you know the size of a building , and you know the dates that you want to arrive at , it would not be difficult to "discover" the unit of measurement that "proves" your theory correct?
Or am I missing something??
