with the mental activity which determines vocation, and without which it is impossible to rise above mediocrity: this element of success is of more difficult attainment, as it depends on natural dispositions carefully trained from the earliest infancy.

The peculiar mental activity suitable to any profession may be resolved into two principles-aptitude and capacity. Aptitude is an inclination, either the gift of nature, or the result of certain habits, which fits us for a particular kind of occupation. Capacity consists in the development of the physical, moral, and intellectual qualities for this kind of occupation.

Although all physical, moral, and intellectual qualities which constitute the perfection of human nature are desirable in every individual, whatever be his position in life, it must, nevertheless, be granted that certain offices, professions, and pursuits require for their successful fulfilment the predominance of particular qualities and special branches of knowledge. In order, therefore, to complete our classification of the objects of education, we subjoin in the following tabular arrangement a designation of the principal professions, with an indication of the aptitude, capacity, and instruction which are more especially required for each.

We have adhered, in the construction of the Tables, to the order which has been introduced through the preceding pages, while noticing the different classes of faculties and the acquirements arising from them, so that the physical, moral, or intellectual character of each profession may be perceived at a glance. The relative importance of the different acquirements of education and instruction may also be known by ascertaining the number of professions in which they enter as essential elements of success.
