Greedy fellow, to choose the largest! but, n'importe, it brought its punishment.
Palliser and I having eaten carefully, were just beginning to feel uncomfortable, when up jumped Benton, holding his throat with both hands, crying, "My throat's full of pins.

I'm choked." "We are poisoned, no doubt of it," said Palliser, in his turn.

"I am choking likewise." "So am I." There we were all three, with our throats in an extraordinary state of sudden contraction and inflammation, with a burning and pricking sensation, in addition to a feeling of swelling and stoppage of the windpipe.

Having nothing but brandy at hand, we dosed largely instanter, and in the course of ten minutes we found relief; but Benton, having, eaten his large yam, was the last to recover.
There must have been highly poisonous qualities in this root, as the quantity eaten was nothing in proportion to the effects produced.

It is well known that many roots are poisonous when raw (especially the manioc), which become harmless when cooked, as the noxious properties consist of a very volatile oil, which is thrown off during the process of boiling.
