I am glad to find that so high an authority as Professor Flower has come to this same conclusion.
The extraordinary cases given in a former chapter, of widely different fishes possessing electric organs--of widely different insects possessing luminous organs--and of orchids and asclepiads having pollen-masses with viscid discs, come under this same head of analogical resemblances.
But these cases are so wonderful that they were introduced as difficulties or objections to our theory.
