Post oc/ ergo propter hoc

Post oc/ ergo propter hoc: (also called the post hoc fallacy) When a writer implies that because one thing follows another, the first caused the second. Confusing with causation.

Example:
" He said his father laid mighty sick once, and some of them catched a bird, and his old granny said his father would die, and he did."
                             (Huckleberry Finn, Pg.45)

In ths quote Jim is impling that because that granny cathced the bird his grandfather died.
