Fifteen hundred palmar prints of normal persons and patients suffering from various diseases were studied and classified as to dermal ridge configurations at the base of digit IV, after the exclusion of main line C courses with endings at one of the palmar marginal regions. This classification scheme, based on the three classical reduction forms of line C (O,X(8),x), resulted in the differentiation of three main groups, A, B, and C. Within these main groups, pattern types with strong similarity were combined to subgroups allowing an easier documentation. Twin and family data were used to test whether the described pattern types, besides the classical abortive states O,X and x of line C (called special and intermediate forms), are heritable and for which of them a remarkable reduction tendency could be established. The results allow us to confirm the main grouping and the assumed reduction tendency of the special forms of group A.
对1500份正常人及患有各种疾病者的掌纹进行了研究，并在排除主线C以手掌边缘区域之一为终点的走向后，根据第四指基部的皮嵴形态进行了分类。这种分类方案基于C线的三种经典简化形式（O、X(8)、x），区分出了三个主要组，A组、B组和C组。在这些主要组内，将具有高度相似性的纹型类型合并为亚组，以便于记录。利用双胞胎和家族数据来检验所描述的纹型类型，除了C线的经典退化状态O、X和x（称为特殊和中间形式）之外，是否具有遗传性，以及其中哪些具有明显的减少趋势。结果使我们能够确认主要分组以及A组特殊形式的假定减少趋势。
