ABSTRACT
The vertical division of the Indian castes, it is true, is into four classes, and not including the Outcastes; but the members of the fourth class are only helpers to those of the first three, who represent the main functional divisions. For this reason, if for no other, it is important that the amount of time devoted to work, at least in this limited sense of the term, should not be excessive; and that the work should not be more monotonously uniform than its nature necessitates. The author should have supposed that it would be better to take the afferent aspect of the nervous system as the first of the functions, the efferent connecting with the muscular system as the second, and the nutritive and circulatory system as the third. In popular language, these are commonly referred to the heart and its deceitfulness. How far this can be physiologically justified.
