"After the discovery of this Toad in the fir-tree, I tried several experiments on Toads, by burying them in closely-sealed flower-pots, at a depth of nearly three feet. I much regret that I cannot find my notes on the subject; but I remember perfectly the main facts of one. The Toad was placed in a flower-pot, with another turned over it, and well cemented together--the two holes in both pots being also closely cemented up. It was buried between two and three feet deep in the garden. At the end of three months I took it up, and weighed the Toad, and found it had lost a very little in weight. This I did again at the end of three months more; it was then quite lively, and had lost again but little in weight. I replaced it as before, and on taking it up the third time, I found the pots had, probably the cement not having been dry when buried, slipped on one side, and the moisture had got in, and consequently the poor Toad was dead, as well as buried! Now, surely if a Toad could live _six months_ hermetically _sealed_ in a flower-pot, without air or food--why not a much longer time?...--Believe me, yours faithfully, "J. PEMBERTON BARTLETT." The Rev. W. J. Bree of Allesley, also an excellent zoologist, alluding to some queries by Mr E. Newman, communicated the following facts:--"I quite agree with you that the statements about Toads found in solid stone are mostly very unsatisfactory. One instance of the kind I have seen, as briefly stated, _Mag. Nat. Hist._, ix. 316. The Toad appeared to me neither more nor less than our common species, although I certainly did not examine it scientifically. The stone was the new red sandstone of geologists; and was brought up, as I was told, some yards from below the surface. I understood the Toad, and the two portions of stone in which it was found inclosed, were deposited in some medical museum at Birmingham. The animal would not have been discovered but for an accident: the workmen were carting the stone away, and the block containing the Toad happened to be placed on the top of a great load, and accidentally fell from the cart to the ground, and, breaking by the fall, brought to light the incarcerated reptile, which, I conclude, was somewhat injured by the fall, as there was a fresh wound on one side of the head, and it appeared to be blind of one eye. The Toad died, I was informed, the second day after it was discovered, partly, in all probability, in consequence of the injury. When I say the block of stone was _solid_, this statement requires some qualification: the two parts of the stone fitted together exactly, and quite close, except where the cavity was in which the Toad lay; but from this cavity there was evidently a flaw on one side towards the extremity, and a discolouring of the substance of the sandstone, so that although the two portions fitted together, they might not have been (on one side of the cavity) very firmly united.
