This organ enables us to form the idea of number, or the plurality of objects. It assists in the recollection of dates and quantities. It enables one to readily understand numbers and their combinations. Its activity takes place, whenever there is a departure from unity. A large endowment of this organ is not essential to the algebraist and geometrician, its functions being limited to arithmetical calculations. Predominant.--One having Calculation predominant, will reckon in his head almost any arithmetical problem that can be proposed to him. If Causality and Comparison are large, he will excel in the higher branches of mathematics, and possess a great fondness for these studies. Large.--With calculation large, one will be distinguished among his acquaintances for his skill in arithmetical calculations. He will be enabled to tell at a glance, operations which to an ordinary accountant require the use of figures. If Causality and Comparison are large, he will excel in solving difficult problems in the higher mathematics, but if these organs are deficient, his talent will be limited to arithmetical calculations.
