A spiral canal* (h,fig. 227), proceeding from each of these sacs, traverses the dermis and epidermis, and, after having made several turns, opens upon the external surface of the skin (at i).t Besides these filaments, the deep surface of the epidermis presents certain irregularities, which may be felt by the finger, and which, under the microscope, appear pointed like thorns ; they seem to be prolongations of the epidermis, but I have not been able to determine their precise nature. The external surface of the epidermis presents corresponding folds and furrows to those already described upon the free sur- face of the skin. It also has numerous orifices or pores, visi- ble to the naked eye on the palms of the hands and soles of the feet, and very distinctly seen by the aid of a lens. Along each of the ridges formed by the rows of papillae are found a series of orifices, arranged in a regular manner, and resem- bling in appearance the puncta in the eyelids. If the skin be examined with a lens during life, while the person is perspiring, drops of the excreted fluid are seen to exude, and form into a small globule, which is soon lost by evaporation, and, after a few seconds, another globule makes its appearance. It is impossible to conceive how several celebrated anatomists could have denied the existence of pores in the Delia Torre, Fontana, and Mascagni believed that the epidermis was organized, and that it consisted of a network of lymphatic vessels. But as Panizza has clearly proved (Osservazio7ii Antropo-zootomico Fisiologiche, 1830, p. 83), the lymph
