be) have their eyes at the sides of the head, and probably they never see the same object with 

 both eyes at the same time. Now these fishes cannot I think possibly see immediately behind 

 them, nor perhaps directly above them, nor even in front of them, and we must presume Nature 

 did not think it necessary for them to be able to do so. As a rule, in fresh water, when 

 feeding, they lie with the head pointed up the stream, and on the look out for their food being 

 carried down by the current, their resting place often being directly below where a stream is 

 partly divided and where it meets again, the current bringing their prey in sight of either one 

 eye or the other. Now we come to their enemy, and observe its eyes, like black beads, placed 

 on its flat shining hairy head, and enabling it to look above it, and consider how well adapted 

 they are placed to enable it to get behind and beneath its prey, and seize it before being 

 observed. Have you detected the otter in its shining hairy hide, impervious to water as well 

 as cold, and which by its natural cunning can secure such a powerful and swift swimming fish 

 as a salmon ? Again, if you consider a seal perhaps as a swimmer not surpassed by any other 

 of Nature's productions ; but even it seems to fall a prey to the huge and almost ungainly 

 looking Polar bear. The seal, however, would I think hardly be able to see what is coming 

 behind him, as his neck will not bend, and his eyes, like those of the otter, seem formed for 

 looking upwards and forwards. When you see a seal, and he sees you, he always comes up 

 with his face towards you. 



As I think I have before remarked, all Nature's creatures are enabled instinctively to find 

 their food, and those feeding on other living things, with either sufficient cunning, or other 

 means, so as to enable them to overtake and catch their prey; but yet none of these creatures
