~be Brt of Smiling. .. .. .. HE smile of a human being is the legitimate descendent T of the grin of a monkey. It betrays a vacant mind. (See Dean, in College Diet.) Physiologically, it is the spontaneous contraction and relaxation of the orbicularis oris assisted by the tevetor lebii supcrioris, the depressor labij inferioris and the depressor anguli oris. As psychologi- cal phenomena, these contractions and relaxations are due to the excitations produced by synthetic vibrations result- ing from the apperceptive functions of the cerebral hemi- spheres. Physiologically and psychologically, the smile is subject to the law of evolution. It is also subject to the laws of mathematics and physics. Where s = intensity of smile, e = distance between "strikes," and k = amount of caramels, the intensity "s" varies directly as amount of car-a- mels or inversely as the square of the distance, or s = ~. Smiles carry in the twilight when ether vibrations do not fall below twenty-one. This cut represents the" grin" of a Freshman. You will note that it lacks refinement and intellectual ex- pression. In fact, it is the twill sister of the grin of an ape. The slightest mental instability will produce it, and its width and loudness is unlim- ited until the Dean refines it. -1-162-1-
