(After Gegenbaur.) Mammals alone (Fig. 230) does this great brain developto such an extent, that it eventually covers all the otherparts of the brain from above. There are also remarkable differences in the relativepositions of the brain-bladders. In the lower SkulledAnimals the five brain-bladders are at first situated onebehind the other in the same plane. If the brain is re-garded from the side, a straight line may be drawn throughall the five bladders. But in the three higher vertebrateclasses, in the Amnion Animals (A
