Rh extension whatever is involved: for, in the next page, he informs us that all visual extension, or extended figure, "must be apprehended as either plane or solid, and that it is impossible even to conceive it otherwise."

Now if that be not teaching, in the plainest terms, that, according to Berkeley, no species of extension is implied in the internal feelings of vision, we know not what language means, and any one thought may be identical with its very opposite.

Here we might let the subject drop, having, as we conceive, said quite enough to prove the truth of our allegation that, in reference to the first question discussed, in which our original visual sensations are represented by Berkeley to be mere internal feelings, Mr Bailey understood and stated those feelings to signify sensations in which no perception of extension whatever was involved. However, as Mr
