To constitute a success in any business a man must have _capacity_, that is, he must have enough of intelligence to meet the demands of the business, and he must have physical strength to support it. A man may have apparently the kind of sense required by a branch of business, and for a time display ability in it, but as the business increases, and its demands become more in volume and intensity, he fails because he has not enough of comprehensive intellect to take it all in. There are also those who have comprehensive greatness of intellect, who are fully capable of understanding all the requirements of a business, but who fail because the body beneath the brain is not sufficient in endurance and nourishment. Dismal failures result, and many useful lives are shortened, because men make the mistake of entering vocations for which they have insufficient mental or physical capacity. A phrenological examination determines beforehand the capacity of the individual and establishes a proper limit, within which he finds success, health, happiness, and the gratification of proper ambition. On the other hand there are many who do not realize how much their capacity is, and consequently remain inert to the great deterioration of body and mind. Nature demands that every man should use his full capacity, and the phrenological examination which reveals to an individual the extent of his usefulness is a magnificent acquisition to him who acts upon it. Action is the natural condition of every part of man. Action develops character, strength and health. Inaction results in paralysis and disease. It is vitally essential that every man should find out his capacity and use it all--no more, no less. This, Phrenology enables him to do. [Illustration: Incapable.] The question of capacity being thus understood, the next is the quality of organization. Quality is the inherent grain or texture of the substance. Men differ in quality as much as do the trees of the forest. You do not use the hickory or the oak for the same purposes that you do the pine or the poplar. There are differences also in the grain of metals, in the texture of fabrics. Gold differs essentially from iron as silk does from flax. Men display an infinite variety of quality, from the strong lumberman of the pine forests, with his corded muscles and angular frame, to the delicate young man who presides gracefully over the ribbon counter in the dry goods store. To illustrate this topic of quality: Riding on the cars one day I noticed a gentleman sitting near me and asked him the rather impertinent question, whether he had not been engaged for many years in handling _delicate_ machinery. "Ah," said he, smiling, "you are a Phrenologist." "Yes, sir," I replied, "we have evidently sized each other up."
