A point of Natural History being suggested, he gave an excellent account of the air-bladder of fishes.

He was very full upon the subject of agriculture, but retired from the conversation when horticulture was introduced in the discussion.
So he seemed well acquainted with the geology of anthracite, but did not pretend to know anything of other kinds of coal.

There was something so odd about the extent and limitations of his knowledge, that I suspected all at once what might be the meaning of it, and waited till I got an opportunity .-- Have you seen the "New American Cyclopaedia ?" said I .-- I have, he replied; I received an early copy .-- How far does it go ?--He turned red, and answered,--To Araguay .-- Oh, said I to myself,--not quite so far as Ararat;--that is the reason he knew nothing about it; but he must have read all the rest straight through, and, if he can remember what is in this volume until he has read all those that are to come, he will know more than I ever thought he would.
