Moderate.--With Calculation moderate, and in a situation which constantly demands the act of ready calculation, one may become highly talented in this respect. He will, however, require time and effort to go through an intricate operation. If Causality and Comparison are large, in ordinary circumstances he will accustom himself to the use of a slate and pencil for all operations of a complicated character. Small.--With Calculation small, one can succeed in arithmetical calculations only by dint of great labour, and then only to a limited extent. If Causality and Comparison are large, he may be capable of the higher branches of mathematics, but the difficulty, which his arithmetical calculations cost him, will render him averse to all mathematical speculations. 8. LOCALITY. This organ gives the power of noticing and recollecting the peculiar position of objects, and gives a desire for travelling, and for the study of geography. It is essential to the scene painter. It strongly aids the power of association. Predominant.--With Locality predominant, one will have an insatiable desire for travelling, roving about, and for visiting strange places, will readily recollect their peculiar position, the localities of the prominent objects of attention, and will be excessively fond of reading geography and works of travels. Large.--With Locality large, one will have a great desire for travelling; and with Acquisitiveness and Inhabitiveness moderate or small, will be prompted to roam about regardless of expense, or of family considerations. In visiting strange places, he readily notices their peculiar localities, and will ever after recollect them. He will be excessively fond of studying geography, and works of travels; and will be enabled to point out the particular position of a sentence in a book or newspaper containing an idea to which he wishes to direct attention. He will never stumble in the dark, and will find his way with little instruction through unfrequented places. Moderate.--With Locality but moderate, one will have but little desire for travelling, and will be nearly regardless of the localities of the places which he visits. He will often lose his way in forests and cities, with which he is not familiar, and will seldom find a place if obscurely situated without great trouble. With Individuality and Ideality large, will have a fine taste for natural scenery, but his descriptions will be vague and unsatisfactory in consequence of his inability to point out the particular localities of the different objects. Small.--With Locality small, one will be extremely unobservant of, and inattentive to the localities of objects. He will often lose his way even in places with which he is familiar, and will be nearly wanting in the attributes ascribed to this organ. 9. EVENTUALITY.
