It may now be within the Lafayette city limits, but iin 1929 it was probably out in the country, between the city of Lafayette and the town of Dayton. Its mailing address would have been Lafayette, I would think. I have no idea where the records might be kept, if there are any. I believe it was mostly for treatment of TB. My mother said that as a girl in the late 1920s or early 1930s she had TB tests at school and tested a false positive and always had to go to the Ross Sanitarium and get a chest Xray.
