Chapter M: S. W., Ala.--Mr. W. says, "Will you inform me, through your Journal or

otherwise, Is iodine entirely lost when it combines with a few drops of a solution of potassa!"

It is not. The following experiment will better illustrate:--Put a few grains of iodine into a clean and dry Florence flask, warm it gradually over a spirit lamp, and the iodine rises in a vapor of beautiful violet color. When cool, pour in "a few drops of a solution of potassa," the iodine disappears at once, and a solution of iodide of potassium is formed; this may be heated to redness without evolving any violet fumes, and yet it is certain that iodine is there, but not in a free but a combined state, and heat cannot expel it from combination with the potassium. Let the flask cool a little, and add a few drops of sulphuric acid; the violet fumes of iodine instantly appear; the sulphuric acid has induced the formation of sulphate of potassa, and expelled the iodine unchanged.

F. B. B., Ky.--Your money is received, and the first Vol. forwarded per order. Thank you for your hearty congratulations.

J. G. P. R. I.--Yours of the 26th in hand. We advise you for the present to say nothing of your discovery: it probably has more valuable importance than you are at present aware of.
