Another secret charm of this book is its inadvertent humor, so much the more delicious because unsuspected by the author. How pleasant is his innocent vanity in adding to the list of the British, and still more of the Selbornian, _fauna!_ I believe he would gladly have consented to be eaten by a tiger or a crocodile, if by that means the occasional presence within the parish limits of either of these anthropophagous brutes could have been established. He brags of no fine society, but is plainly a little elated by "having considerable acquaintance with a tame brown owl." Most of us have known our share of owls, but few can boast of intimacy with a feathered one. The great events of Mr. White's life, too, have that disproportionate importance which is always humorous. To think of his hands having actually been though worthy (as neither Willoughby's nor Ray's were) to hold a stilted plover, the _Charadrius himaniopus,_ with no back toe, and therefore "liable, in speculation, to perpetual vacillations"! I wonder, by the way, if metaphysicians have no hind toes. In 1770 he makes the acquaintance in Sussex of "an old family tortoise," which had then been domesticated for thirty years. It is clear that he fell in love with it at first sight. We have no means of tracing the growth of his passion; but in 1780 we find him eloping with its object in a post-chaise. "The rattle and hurry of the journey so perfectly roused it that, when I turned it out in a border, it walked twice down to the bottom of my garden." It reads like a Court Journal: "Yesterday morning H.R.H. the Princess Alice took an airing of half an hour on the terrace of Windsor Castle." This tortoise might have been a member of the Royal Society, if he could have condescended to so ignoble an ambition. It had but just been discovered that a surface inclined at a certain angle with the plane of the horizon took more of the sun's rays. The tortoise had always known this (though he unostentatiously made no parade of it), and used accordingly to tilt himself up against the garden-wall in the autumn. He seems to have been more of a philosopher than even Mr. White himself, caring for nothing but to get under a cabbage-leaf when it rained, or the sun was too hot, and to bury himself alive before frost,--a four-footed Diogenes, who carried his tub on his back.
