[Math] Quote about errors in math writing

Question

I'm searching for the original reference of a quote that went something like:

"Errors in a mathematics text add an element of surprise to an otherwise predictable plot."

I believe it may have been from the 1700s or 1800s.

Answer 1

A resource might be

Maurice Lecat, Erreurs de mathématiciens des origines à nos jours, Bruxelles : Castaigne, 1935
