尸检时从臀部获取了十份人类皮肤样本。分离角质层并测定其物理尺寸。样品的干厚度 (6.2–19.4 μ) 和干质量 (0.797–2.348 mg/cm2) 具有三倍范围，细胞层数 (14–28) 具有两倍范围。计算出的干密度变化很大（0.88-1.42 gm/cm3），平均值为 1.20。化学分析表明，干密度不仅是组织成分的函数，而且还取决于细胞材料被压缩的程度。
Ten samples of human skin were obtained from the hip at autopsy. The stratum corneum was isolated and its physical dimension determined. The samples had a threefold range in dry thickness (6.2–19.4 μ) and dry mass (0.797–2.348 mg/cm2) and a twofold range in the number of cell layers (14–28). The calculated dry densities varied greatly (0.88–1.42 gm/cm3) with a mean value of 1.20. Chemical analyses showed that dry density was not simply a function of composition of the tissue but also depended upon the degree to which the cellular materials were compressed.
