The quote can be found in one of Russell's well-known essays:
An Outline of Intellectual Rubbish
"If the matter is one that can be settled by observation, make the
observation yourself. Aristotle could have avoided the mistake of
thinking that women have fewer teeth than men, by the simple device of
asking Mrs. Aristotle to keep her mouth open while he counted. He did
not do so because he thought he knew. Thinking that you know when in
fact you don't is a fatal mistake, to which we are all prone. I
believe myself that hedgehogs eat black beetles, because I have been
told that they do; but if I were writing a book on the habits of
hedgehogs, I should not commit myself until I had seen one enjoying
this unappetizing diet. Aristotle, however, was less cautious. Ancient
and medieval authors knew all about unicorns and salamanders; not one
of them thought it necessary to avoid dogmatic statements about them
because he had never seen one of them."

Probably not so unusual that a writer might use the same example more
than once in his works -- even verbatim. Was it just the Aristotle
quote you found, or the whole paragraph, as I excerpted in my answer.
Anyway, the Russell essay is on the web, as I noted, so you have the
entire document at your ready disposal, and it also appears in the
print volume "The Basic Writings of Bertrand Russell" as I indicated.
So it appears now you have not just one, but two, viable answers to
your question.
