a natural association between them we do not mean that it is congenital, so that the association is formed in the mind of every individual from his or her birth. If it were so. every baby should have as good perceptions as any grown-up person. All that we mean by a natural association is that it bas a basis in the constitution of things and that it is most frequently met with in the experiences of an individual.

The knowledge of the same rose, under the same external conditions, will be an inference for another person when, for want of repeated experiences, its colour does not immediately call up its touch and smell, but suggests them as distinct ideas or images on the ground of its similarity to the colour of roses.

The fragrance of sandalwood may be directly known from its sight by those who are closely acquainted with it, but for others its visual appearance may only be a sign from which to infer its fragrance. When I go to a foreign country I can barely infer
