To which might be added the modern abuse of Coal tar products, patent medicines. Such wanton treatment weakens the organism, abnormally deranged and wholly altered. Irritability and sensibility are increased or decreased, hypertrophy and atrophy, softening and indurations in certain organs and organic lesions are produced. Such are some of the results of nature's efforts to protect the organism against complete destruction by aggressive treatment with pernicious drugs.
