    (LXVI.) The capacity of increased dilatation of arteries, and consequent local fulness, independently of increased action of the heart, is proved by many facts besides those to which I have last alluded. Let a grain of sand enter the eye, and almost immediately we perceive an increased fulness of blood in a large proportion of the vessels of the Conjunctiva, and an influx of red globules into those, in which they were not before visible. The local application of certain degrees of ex- cessive heat produces similar effects upon various vascular parts; and like consequences occur from the application of other substances, which are called Stimuli, and which are found to have the power of causing sudden contraction in muscular fibres, which they are made to touch. To these may be added the increased afflux of blood to the subcutaneous vessels of the face and neck from shame, already mentioned; the dilatation of the papillae and genital system from mental and bodily causes, together with other examples* which will be hereafter enumerated, and which will not only prove the general principle, but tend to shew the specific effects of particular causes on appropriate parts of the sangui- ferous system.
