Observation du passage de Venus en 1882 - in French and Portuguese

Here's a cool find that turned up when I did a search for "un seul instant" and "um só instante", looking for pages that contained both sentences. This time, instead of a simple page I was presented with an entire book with French and Portuguese side by side, and not only that but about a very cool subject - the passage of Venus in 1882. If you like French and Portuguese and astronomy, this book is for you.
