Prof. O. S. Fowler, says: "It is adapted, and adapts men to the divisibility of matter, or that natural attribute which allows it to be subdivided indefinitely. Yet each division maintains a personal existence. It thus puts man in relation and contact with a world full of things for his inspection, as well as excites in him an insatiable desire to examine everything. It is therefore the _looking_ faculty. Its distinctive office is to observe things. It asks: 'What is this?' and says, 'Show me that!'... Before we can know the uses, properties, causes, etc., of things, we must first know that such things _exist_, and of this Observation informs us." This Quality is largely involved in the process of Attention. It usually manifests in the form of _involuntary attention_, that is, attention to interesting things. But, under the influence of the will, with Firmness large, it manifests _voluntary attention_, or attention or study of objects not interesting in themselves, but which it is important to study and know. It is largely developed in children and undeveloped adults in the phase of curiosity or desire to observe _new_ things. In adults, of developed minds, it manifests as attention to things of _material interest_ and important subjects or objects of study. This Quality is the master of its associated Qualities in this group, and is involved in all of their activities. It manifests outer form in the middle of the lower part of the forehead, between the inner ends of the eyebrows, and above the top of the nose--"just above the root of the nose," in fact. Prof. O. S. Fowler says: "When it is large, the eyebrows flex downward at their nasal ends, and the lower part of the forehead projects. When it is deficient, the eyebrows are straight at their inner ends, and come close together" (See group figure). FORM. This Quality manifests in a cognizance, appreciation, and recollection of the _form and shape_ of objects observed. Those in whom it is large most readily perceive, recognize and remember details of form and shape, faces, etc. It manifests outer form between, and slightly above, the eyes, on each side of Observation (see group figure). When large it tends to push the eyes apart and outward. Sizer says: "The width between the eyes is the indication of its development.... When small the eyes are nearer together, which gives a pinched expression to that part of the face; when the organ is large, the eyes appear to be separated, pushing away from the root of the nose. Distinguished artists have the eyes widely separated." Audobon said of Bewick, an eminent English wood-engraver, "His eyes were placed farther apart than those of any man I have ever seen."
