The Clinical Chemistry laboratory in the Old Pathology Building used body fluids, like spinal fluid, blood, and urine, to diagnosis diseases like syphilis, meningitis, tabes, and paresis. Syphilis, a bacterial infection, was one of the leading causing of mental illness during the time before the discovery of penicillin. This lab boasts a hand-cranked two-vial centrifuge and original plumbing fixtures.
