The tropocollagen in the lungs of chicken embryos increases rapidly between the 13th and 16th day of development, then keeps constant levels and equal ones to those of the adult until the birth. The proline hydroxylase activity is highest in the lung of the embryos of 13 days old, diminishes rapidly between the 13th and 16th day, after that moderately but constantly until the birth, when it is equal to the levels found in the adult. The procollagen has a behaviour comparable to the one described for the proline hydroxylase.
