Update Snow's cholera map with the original.

The current image used in the foreword seems to be Tufte's recreation, and not Snow's original. It would be good to either mention that, or use the original one created by C.F. Cheffins using bars to represent deaths.

Hello!
The original image created by Cheffins would be this one (http://matrix.msu.edu/~johnsnow/images/online_companion/chapter_images/fig12-5.jpg), right?

If y'all agree that the image João linked to is the Cheffins original, I'd be happy to update the chapter. Thank you!

[tillnagel]

Yes, that's the one.

Okey dokes. Will try to update it this weekend. Thank you!
