Hensleigh says to say Brain per se thinks is nonsense; yet who will venture to say germ within egg, cannot think — as well as animal born with instinctive knowledge.— but if so, yet this knowledge acquired by senses, — then thinking consists of sensation of images before your eyes, or ears (language mere means

Sykes43 on Formica indefessa placed table in cups of water which they waded or swam across.— they then stretched themselves from wall to table.— table being removed a little further, they ascended about a foot & then leapt across. (Col Sykes compares this with pidgeons finding their way home — there is something wrong in comparing these cases, when agency is unknown, with simple exertion of

A wasp, on a gravel walk, had caught a fly nearly as large as himself; kneeling on the ground I observed him separate the tail and the head from the body part, to which the wings were attached. He then took the body part in his paws, and rose about two feet from the ground with it; but a gentle breeze wafting the wings of the fly turned him round in the air, and he settled again with his prey upon the gravel. I then distinctly observed him cut off with his mouth, first one of the wings, and then the other, after which he flew away with it unmolested by the wind."
