The irritation caused by the growth of Trichophyton in the epi- dermic structures leads to the symptoms which are characteristic of ringworm in its various forms. These symptoms are symptoms of inflammation, the special characters of the inflammation de- pending on the peculiar action exerted on the living tissues, particularly on the blood-vessels, by the new substances produced in the epidermis by the fungus appropriating the elements necessary to its growth. The fungus itself, and its new pro- ducts, are the combined causes of this inflammation. The nature and degree of the symptoms thus produced depend on the anatomical structure of the part in which the fungus grows, and on the special irritability or vulnerability of the tissues of the patient. A consideration of these various symptoms leads us to the practical part of our task, that which concerns itself with the etiology, pathology, diagnosis, and treatment of ringworm. CHAPTER II. ETIOLOGY. The etiology of ringworm is concerned with the circumstances that lead to the contact of the spores of Trichophyton tonsurans with the surface of the skin; and with the condition of the skin that causes it to be an appropriate soil in which the fungus can take root and grow. First in order of the causes of the disease are the causes that lead to the contact of the spores with the skin. The most frequent and direct cause is that of the simple contact of one person with another, and, in the great majority of cases, of one child with another. The hairdressers' tools are not unfrequently the conveyers of contagion. Not only does he of necessity cut the hair of children who unknowingly suffer from ringworm, but the parents of the affected children, who are advised to have the
