Blood groups in children

Until recently, the question of belonging to blood groups in Landsteiner's sense has interested many authors. A large number of works in this direction has already been accumulated. Beginning with the guiding studies of Dungern and Hirszfeld, Jansk and Moss and ending with the recent works, one can see how medical thought in various countries has done much work to trace the grouping of people by blood according to the topography of examination sites and from this point of view understand the problem of heredity, give certain guidelines for the clinic in blood transfusion, gemotherapy and homoplasty, open new ways of forensic medical examination, etc. A great deal of experience has been gained in this respect. According to Prof. Rubashkin's calculations, 29,000 examinations were carried out by Russian authors alone until 1927.
