Have you heard of the saying, "A leopard can't change his spots"? I'm currently reading a work from 1789, that contains 29 letters that a lady wrote to various people regarding God and Methodism. In one of the letters, she says that God can "change a leper's spots." So, here's the pressing question: Was the original saying about lepers, and it changed to leopards later? Do lepers have spots (I didn't think they did, but I don't know much about leprosy)? Did the saying just change because someone didn't repeat it correctly?

If anyone knows the answer to this, please let me know!

Thanks,

Kristin
