depth, activity, and quality of lung power.  They do not breathe in or use much oxygen, so they are lacking in energy.  Such people are not predisposed to industry.  Love of work—­love of the game that causes a man to be interested in every phase of his work—­is not, however, wholly dependent upon energy.  It is something in the very heart and fiber of the man.  Willingness to work, perseverance in work, and decision come under disposition to industry.

[Illustration:  Fig. 4.  H.G.  Wells, Novelist and Economist.  A man of physically frail type, with natural mechanical leanings.  Inventive, creative, industrious, humanitarian.  Because of his mechanical ability, he uses his creativeness for constructing novels dealing with mechanical invention.  Because of his humanitarian instincts, he writes of social and economic world problems.  Note large upper portion of head, especially from center of forehead to sides of head; also prominence of brows; large nose, and long head.]

[Illustration:  Copyright American Press Association.  FIG. 5.  Mr. Henry Ford, Automobile Manufacturer and Philanthropist.  Mr. Ford is of the physically frail type, with a goodly admixture of the bony and muscular element.  His natural mechanical bent, therefore, took the intellectual form of invention and organization.  His sentiment, responsiveness, sympathy, and idealism are shown by high, rather narrow head, fine texture, height of head just above temples, and gentle, kindly, genial expression.]
