Harmonica

"Thanks for the harmonica you gave me for Christmas," little Joshua said to his uncle the first time he saw him after the holidays. "It's the best present I ever got."

"That's great," said his uncle. "Do you know how to play it?"

"Oh, I don't play it," the little fellow said. "My mom gives me a dollar a day not to play it during the day and my dad gives me five dollars a week not to play it at night.

He edited (from 1909) Kolloidchemische Beihefte and other journals and as the founder (1922) and president of the Kolloid Gesellschaft, Ostwald advanced research in colloids.
