The recent publication of the study of 5.000 routine Wassermann reactions in students at the University of Minnesota has prompted us to report our observations in a series of 2,872 consecutive examinations of patients seen in private practice.
It is a matter of no little difficulty to determine accurately the incidence of any particular disease. This is especially true of syphilis and for obvious reasons. Few health departments require that the disease be reported, and in such communities as make this requirement it is evaded by the physician and patient alike because of the stigma which, to the lay mind at least, attaches to the diagnosis. Relatively few deaths are reported as of syphilitic origin, for like reasons. As a result, the problem is one of great perplexity and has been attacked by numerous investigators from many angles.
