“Yes, at the grammar-school, and I am going to ask Mr. Harmer to let me give you a course of lectures at your school next autumn, similar to those I give at the grammar-school.”
“Please do, sir!” exclaimed Walter; “and let me help you with the experiments.”

“I should like to be a chemist, sir!” exclaimed Walter. “I hope that when I leave school father will let me be one.”
“Please, sir,” inquired Steve, “can you do any kind of analysis?”
