Uncanny Tales #48

A chemist thinks that he has invented a compound that makes people obey him because he gave some to a dog and the dog obeys him. He goes to a small town and convinces the people to drive out the mayor and install him. He abuses his people by hiking taxes to feather his own nest and the people send him packing. He is surprised that they did not obey him but then he realizes his compound doesn't work and the dog only obeyed him out of love and trust, the same way his influence worked at first until he abused it.
