No doubt osteopathic lesions frequently determine the location of the wheals. These lesions affect the innervation and thus establish a basis for the reflex vasomotor effect. This is in the nature of spasm of the cutaneous vessels quickly followed by dilatation with exudation of serum. The irritant probably acts on the walls of the blood vessels. =Treatment= consists of thoroughly emptying the bowels by warm water enema, correcting the diet, toning the viscera and adjusting the osteopathic lesions. Thorough attention to the patient’s environment, daily habits and occupation are of value. Warm soda baths will relieve the itching. =Acne= is a common skin disorder that is characterized by an inflammation of the sebaceous glands of the nature of papules, tubercles or pustules. The face, shoulders, chest and back are the regions usually involved. It generally, appears about puberty. Blackheads is the starting point; these are accompanied with greasy skin and dust, and influenced by micro-organisms and more or less intestinal disorder. The general or systemic health no doubt affects the local disorder, as in many skin diseases; for various intestinal derangements as indigestion, constipation, etc.; pelvic and menstrual irregularities; general ill health; anemia, etc. affect circulatory, glandular and nervous integrity. Any disturbance of normal elimination is important. The =treatment= consists of careful attention to the general health and to the local innervation of the face or region involved. Measures that tone the bodily organs such as outdoor life, regular habits, plenty of sleep and correct diet are important. In some cases the X-ray is of value. ANIMAL PARASITES Tape Worms =Varieties.=—Taenia solium; taenia saginata; bothriocephalus latus. The larvæ of tape-worms are introduced into the intestinal canal by food and drink. The parasite reaches adult growth in the intestines. The larval forms are then found again in the muscles and solid organs. =Taenia Solium.=—This is derived from the hog, and is the most common form in this country. When mature it is from two to four yards in length. The head is small, about the size of a pin, and provided with four cup-like suckers surrounded by a double row of hooklets, hence it is called the armed tape-worm. The head is fastened to the body by a thread-like neck, and following the neck, the body occurs in segments. The sexual organs, both male and female, occur in the center of the broad surface of the segment. The segments are about one millimeter in length and seven or eight millimeters in breadth. There are thousands of ova in each mature segment. The worm attains its growth in about twelve to fifteen weeks, after which time the segments are shed and passed. For further development the ova must gain entrance to the stomach of a pig or of man, and passing from the stomach they may reach the muscles and organs and develop into larvæ or cysticerci.
