Growth of the cricoid ring in infants is studied. In the first two weeks of life a small ring seems correlated with the fact of early infant death. Therefore we suggest that mortuary specimens at this age are not a reliable guide to the size of the cricoid in thriving infants. Rates of growth from ages of two weeks to three years are given for the specimens examined. Comparison with similar measurements carried out in England show that the specimens collected here were systematically smaller for a given age.
对婴儿环状软骨环的生长情况进行了研究。在出生后的头两周，较小的环状软骨环似乎与婴儿早期死亡这一事实相关。因此，我们认为这个年龄段的尸体标本并不能可靠地反映健康婴儿环状软骨的大小。文中给出了所检查标本从两周到三岁的生长速率。与在英国进行的类似测量结果相比，发现这里收集的标本在相同年龄时系统地偏小。
