. Elements of pathological anatomy. Anatomy. S96 SKIN. [chap. X. minate either by resolution, desquamation, superficial exco- riation, and in the formation of soft yellowish scabs. Their duration varies from a few days to several weeks, or even months. Scabies is an inflammatory affection, contagious, accom- panied by an insect, and characterized by pointed vesicles, transparent at the summit, of a light rosy tint, and filled with a thin, viscid fluid. By scratching, these vesicles are easily broken, when their contents escape, and expose a correspond- ing number of small, red, inflamed specks, which frequently run into each other. The eruption is sometimes very trifling, but in many cases it is very extensive, covering a large por- tion of the cutaneous surface. It never, however, appears on the face; and, what is singular, it is always most abundant at the flexures of the joints and between the fingers, owing, doubtless, to the great delicacy of the skin in these situations. In infants, the disease is usually developed in four or five days after exposure to the contagion; in adults, in from one to two weeks. A slight itching is first felt in the parts, which is invariably increased by the warmth of the bed, by sitting near the fire, or by stimulating food and drink, and, in plethoric habits, is sometimes almost intolerable. No fever attends this affection. It has been already stated that this disease is accompanied by an insect. Whether this is a constant occurrence is not fully determined, but that it is occasionally ob- served is established be- yond contradiction by the recent researches of Dr. Renucci, of Paris. The insect, the existence of which was long ago sus- pected, if not actually de- monstrated, by some of the older physicians, is called the acarus, or itch-ciron, and is seldom to be found in the vesicle, but almost always in a small epider- mic canal, which leads from it, and which is either Fig. Please note that these images are extracted from s
