Andrew,
I realize your post is now 15 years old, but if by any chance you see this: please e-mail me at
mitra.sharafi@wisc.edu , as I'd love to discuss Dr. William Center with you. I am a historian working on a project on medico-legal history. Dr. Center is a figure of interest to me for his work as Chemical Examiner of Punjab in the 1870s-80s.
Best,
Mitra
