Natural language is the great tell-tale of all the faculties and head posture tells the most.
The phrenological rule is that each Faculty in action throws the head into a line with itself - the intellectual in front canting the head forward, etc. Chest posture is most expressive of both one's amount of gender, and of its existing states. Soldiers in marching and many men in processions manifest it the more as they are the better sexed. All women with a loved man always set their bust forward towards him. Those who observe how much better the same woman looks when erect than stooping, with shoulders set well backward than forward, would surely never be caught in this stooping posture.
