Facial index??

[Ross]

There seems to ba contradiction...

Bizyg. diameter of this person is 156, facial height is 138...

So Bitragion diameter must be around 166, but it's enormous, and greater than head's breadth.

[Ross]

So it seems Coon was using Bitragion diameter for FI?

And this illustration is not correct?

"21" is not the facial breadth? It's "29" actually?
