Homologous parts, as has been remarked by some authors, tend to cohere; this is often seen in monstrous

and nothing is more common than the union of homologous parts in normal structures, as

causes the remarkable diversity in the shape of their kidneys. Others believe that the shape of the pelvis in the human mother influences by pressure the shape of the head of the child. In snakes, according to Schlegel, the

The nature of the bond →of correlation is frequently quite obscure. M. Is. Geoffroy St. Hilaire has forcibly remarked, that certain malconformations
