There is great interest at the present time in the most poisonous of spiders, the black widow. This interest has been stimulated by the belief on the part of some biologists that its geographical range, which heretofore has been considered southern is being greatly extended. Scientific journals have been reporting the appearance of the black widow in states where it has not previously been found until on January 22, in Science, the statement was made that Minnesota and Iowa were the only states in which it had not been found. The writer believes that Iowa may be added to the "black list."
