[Tim Strzechowski]

298.21:  "Want to get an idea of your gnathic index, and that moustache is in the way."
 
gnathic index,   the degree of prominence of the upper jaw, expressed as a percentage of the distance from basion to nasion. Called also alveolar i.

Relation between the basialveolar (basion to alveolar point) and basinasal (basion to nasion) lengths: (basialveolar length × 100)/basinasal length; the result indicates the degree of projection of the maxilla or upper jaw. 

Synonym: alveolar index.

Also notice the mention of various head features:

"Brock Vond's nostrils went wide, a vein began to beat next to one eye [...]"

"Zoyd looked back, eyes swollen, mouth shut, sweating, his hair, not to mention his brain beneath, all matted down [...]"

Coupled with Brock's examination of Zoyd's gnathic index, this almost has a post-Darwinian Naturalistic quality:
