Its colour is so dark as not to be distinguished from black.

P. M. COLQUHOUN.

Corfu, 7th Nov., 1860.

Sir Emerson Tennent, in his popular and excellent work on Ceylon, gives an account of "snake stones" apparently similar to the one at Corfu, except that they are "intensely black and highly polished," and which are applied, in much the same manner, to the wounds inflicted by the cobra-capella.

QUERY.-Might it not be worth while to ascertain the chemical properties of these stones, and, if they be efficacious in the extraction of venom conveyed by a bite, might they not be as successful if applied to the bite of a mad dog as to that of a cobra-capella?

CHAPTER LI.

When we separated for the night, which we did at eleven o'clock, Margrave said,—

"Good-night and good-by. I must leave you to-morrow, Strahan, and before your usual hour for rising. I took the liberty of requesting one of your men to order me a chaise from L——. Pardon my seeming abruptness, but I always avoid long leave-takings, and I had fixed the date of my departure almost as soon as I accepted your invitation."

"I have no right to complain. The place must be dull indeed to a gay young fellow like you. It is dull even to me. I am meditating flight already. Are you going back to L——?"

"Not even for such things as I left at my lodgings. When I settle somewhere and can give an address, I shall direct them to be sent to me. There are, I hear, beautiful patches of scenery towards the north, only known to pedestrian tourists. I am a good walker; and you know, Fenwick, that I am also a child of Nature. Adieu to you both; and many thanks to you, Strahan, for your hospitality."
