The Chemist andDruggist, quotes from the Bedford College Magazine some curious specimens of students' answers about nitrous oxide. One of these is the following: "Nitrous oxide is often called laughing-gas. With this gas they pull out teeth; this is the reason they call it laughing gas." Another is: "Nitrous oxide has a sweet taste, has a soothing influence, is an æsthete." Others there were that were quite as wide of the mark—but these will show how superficial an impression can be made on the mind of a chemistry student.
