Out of the large collection of case records in the syphilis clinics of the New York City Department of Health a sample of 15,090 records was taken at random from the active files, and studied to ascertain certain facts regarding the primary or chancre stage of syphilis in our clinic case load. Among the 15,090 case records were 971, or 6.43 per cent, indicating a definite diagnosis of chancre by the darkfield method at the time of admission to the clinic service. There were in addition, 7,386 records giving a definite history of chancres, 48.95 per cent of the total.
