On the other hand, no class of patients is apt to exhibit the low cunning of the insane in so marked a degree as the epileptic. Not only this, but even during ordinary health between attacks they may, owing to their disposition, plan cunningly to simulate some of the symptoms of an attack and then accomplish a really malicious purpose with deliberation. In a word, these patients present to the alienist the most serious problem in the calculation of responsibility that can possibly be imagined. As an expert has declared, "It is ofttimes impossible to decide whether an assault has been committed with full consciousness, or in a transient but blind epileptic fury." There are a series of attacks that occur in which there are some almost typical convulsive movements followed by loss of consciousness that simulate epilepsy very closely, yet are not true epilepsy. These attacks are usually due to some {256} cerebral affection or perhaps to some injury of the brain. Chronic intoxications, that is, the long continued presence in the body in noxious quantities of some poisonous substance, are especially liable to cause these attacks, which are called from their character epileptiform. Characteristic epileptiform convulsions occur as the result of lead poisoning or from alcohol or syphilis. Lead poisoning, for instance, may very well occur in others than those engaged directly in the manufacture or handling of lead. Certain persons are extremely susceptible to the influence of lead. In them such small amounts as are contained in a hair-dye, or even in water that is being used by others without any bad effect, may cause particularly the nervous symptoms of lead poisoning. Chronic alcoholism is also a relative term in this regard. Some persons are able to stand very large amounts of alcohol without serious consequences, even though it is taken for long periods. Others succumb to its influence very rapidly; some especially susceptible people are liable to suffer from epileptiform convulsions almost whenever they take alcohol to excess. This masked epilepsy may take on an anomalous form. The story is told of a student of a Catholic college in the eastern part of this country, who, during one vacation, was given as a joke by some friends a rather strong dose of liquor in a glass of ginger ale. He was very thirsty at the time and did not notice the presence of the alcohol until he had swallowed the whole glass. As he was well aware himself he was extremely susceptible to the influence of alcohol. During the course of half an hour he became almost wildly drunk, and going down the street with an open pocket-knife he murdered the first person whom he met, who happened to be an entire stranger to him. The occurrence took place in New Jersey, and, in spite of every influence that could be brought to bear--the incident took place some thirty years ago--Jersey justice would have its way and the young fellow of less than twenty was hanged.
