I believe EpiMap has the Snow data (but I'm not sure).  The
ESRI book on GIS for Health Organizations shows the snow
example in EpiMap.

If anyone has access to the Snow data, please post to the
list.  I'm sure a lot of us would like to use it.

Lance

PS As discussed in the two references, we also need to describe
*which* Snow map/data we're using...there were several maps 
in 1854, and various versions in reproductions.
