What does the sergeant-major say is special about the monkey's paw?

The Sargeant-Major says the paw has a bit of magic about it.... a spell cast on the paw by an old Fakir.

"And what is there special about it?" inquired Mr. White as he took it from his son, and having examined it, placed it upon the table.
"It had a spell put on it by an old Fakir," said the Sargeant-Major, "a very holy man. He wanted to show that fate ruled people's lives, and that those who interfered with it did so to their sorrow. He put a spell on it so that three separate men could each have three wishes from it."
