Four little children threatened with starvation because of a cicatricial esophageal stenosis due to the swallowing of some form of caustic alkali to which the laxity of our laws permitted them to be exposed were under my observation within a year. These four cases are my excuse for addressing you on this subject. The law requires that the druggist shall label corrosive poisons "Poison" and the careful druggist adds antidotal advice. Next door to the druggist the grocer sells corrosive poisons having on the label not only no hint of caution, but having directly misleading statements, such as "won't injure the hands," "will not harm the most delicate fabric," etc. One brand of concentrated lye is marked "Caution." When I encountered this I thought, "At last I have found one preparation on the market whose manufacturer has a conscience that compels him to give some advice protective to little children."
