Human foetal measurements between 50 and 150 days of gestation, in relation to crown-heel length.

Weights and a number of linear measurements were related to crown-heel length in fresh apparently normal foetuses ranging from 8 to 21 weeks' post-menstrual age. The average relationships agreed remarkably well with results reported many years ago on the basis of preserved specimens mostly from spontaneous abortions. There was no evidence of sex differences.
