ResumoI r\’ THE study of castor bean dust hypersensitiveness we have an especially interesting phase of the dust problem in general. It is an unusual substance, and the instances in which individuals come in contact with it demonstrate the insidious manner in which antigenic dusts may be the inciting cause of allergic manifestations. The correlation with animal experimentation is singular. BerntonI in 1923 reported the case of an individual who worked in the laboratory of the U. S. Bureau of Agriculture for a period of three years with no ill effects. After that time, however, he developed symptoms of sneezing, lacrimation and sweating of the forehead, etc. In the army for a period of two years he was absolutely free from attacks. Upon his return to the laboratory, he again developed these symptoms. Skin tests with an extract of castor bean mere positive, and Bernton concluded that occupational sensitizat,ion to castor bean is a definite condition. A few months later, Robbins’ reported the case of a student who, when working with the castor bean, developed apparent attacks of hay fever which became progressively more frequent and severe. It was then discovered that castor bean was the cause of the condition. The effect of the plant itself was similar to that of the bean. There was another instructor whose symptoms were entirely limited to the eyes. Shortly after that, Snel13 reported his own case of hypersensitiveness to castor bean. He stated that for years he handled the castor bean with impunity until one day he developed a severe attack of hay fever and violent itching of the skin. His attacks of hay fever occurred only in the laboratory the first three days of the meek when he taught the
