You know another neighbor who is exceedingly cautious, timid, safe wise, and hesitating; who always looks at the objections and difficulties in the way of a particular measure, instead of at its advantages; who always takes abundant time to consider, and is given to procrastination. Learn the location of Cautiousness, and see whether he has this phrenological organ as conspicuous as you know this faculty to exist in his character. By pursuing such a course as this, you can soon arrive at a sure knowledge of the truth or falsity of phrenological science; and this is altogether the best mode of convincing unbelievers of its truth, by means of the marked coincidence between the Phrenology and character of those they know; and it is not possible for the human mind to resist proof like this. To promote this practical knowledge--the application of this science--we give the following RULES FOR FINDING the organs, fully assured that we can fill our pages with nothing more interesting or useful. Follow these rules exactly, and you will have little difficulty in finding at least all the prominent organs. Your first observation should be made upon TEMPERAMENT, or organization and physiology, with this principle for your basis: that when bodily texture or form is coarse, or strong, or fine, or soft, or weak, or sprightly, the texture of the brain will correspond with that of body, and the mental characteristics with that of brain. Still, it is not now our purpose to discuss the influence of various temperaments upon the direction of the faculties.
