MATERIALS AND METHODS
As part of a routine health control, our laboratory receives blood samples for syphilis antibody screening from most seamen hired on Norwegian ships in Norwegian ports. Sera from all foreign scamen hired during one year were selected for this study. The samples were coded by serial numbers and stored frozen until tested. After the typings were completed, the names and addresses of the seamen were disclosed to be grouped into the different population samples. Sera from 42 Tibetan refuges boys were also included in the material. The distribution of hlood groups among these boys has recently been published (6). Starch gel electrophoresis was performed using a horizontal discontinuous system of buffers. Potato starch (obtained from Jaeren Potetmelfabrikk, Klepp, Norway) was hydrolysed at 44" C for 75 mins.(6 ml conc. HC1+ 600 ml acetone+ 300 g starch). The following buffer solutions were used: anodic vessel: 23.5 g citric acid+ 31.4 g Na, HPO,* 2H, O, aqua dest. ad 2 litres.
