29. "History of Magnetical Discovery."

—In the Gentleman's Magazine for April 1840, I find the following notice:

"Thomas Stephens Davies, Esq., Fellow of the Royal Societies of London and Edinburgh, Professor of Mathematics in the Royal Military Academy at Woolwich, and Author of the History of Magnetical Discovery, &c. &c."

Being interested in all that concerns the late Mr. Davies, I shall feel much obliged to any one who will state where I can find the History here alluded to. I may add that I am acquainted with his papers on "Terrestrial Magnetism," published in the London Philosophical Transactions for 1835-6; but since they do not much partake of the character of "History," they can scarcely be the papers intended.

30. George Chalmers.

—Can any of your correspondents inform me what became of the MSS. of the late Mr. George Chalmers?

On the titles of many of the older poets and dramatists of Scotland I have met with his notes referring evidently to some MS. list of the lives of such writers in his possession. My inquiry has reference, therefore, more particularly to the MS. in question, which has not, I think, been published.
