    Incidence oí Deformities oí Absence The compilation of the material was commenced in 1943. It comprises practically all patients with absence deformities of the upper extremities living in this country and born before January 1, 1947. The names and addresses of the patients were procured through the kind assistance of various institutions, including the Orthopaedic Hospitals of Copenhagen and Aarhus, the Invalidity Insurance Council, and all general hospitals in Denmark. The general practitioners have also contributed a great deal toward making the series as complete as possible. Of the total number of 625 patients 274 (43.8 per cent) were found in Jutland, 186 (29.8 per cent) distributed over the various islands, and 165 (26.4 per cent) in Copenhagen. The percentage distribution of the Danish population is as follows*): Jutland 45.1 percent, the various islands 31.9 per cent, and Copenhagen 23.0 per cent. Thus, congenital deformities of absence are equally distributed over the entire population, with no accumulation of patients in the remote districts, especially the small islands, where inter marriage is common. The incidence of the various deformities in the Danish population (about 4,024,000) is as follows: Deformities of absence Number of pts.
