Description
The importance of the head made it a favourite problem in comparative anatomy, but it was also the most complex, even when traced back into the embryo. Modelling structures after sections allowed comparison of axolotl (1 and 2), frog (3) and salmon (4 and 5). Models 2 and 5 represent more advanced stages. (Wh. 6399 - 6403)
