Hello HN39,
Yes, the tephigrams on Figs 10 & 11 would be interesting. I've ignored them so far because, even using browser zoom magnification, I'm unable to read the blurred scale numbering - let alone the other information.
[EDIT] Eureka: have belatedly noticed the enlargement facility he kindly provided!
