Most uncommon American Edition of Blackwood's Edinburgh Magazine (Edinburgh & New York editions are identical) for March 1860 is in very good condition. A few tiny marginal brown dots here and there. 

See photo #2 for complete contents

Some highlights of the outstanding content I find here includes:   

The able G.H. Lewes contributes an essay on Henry Fielding's now long standing classic early novel, Tom Jones (1749).  

British Army officer J.W. Thompson's detailed narrative outlining the principles, past and present, of "Volunteer Cavalry Movements" of the day. This work was no doubt scrutinized by past and future American West Point graduates, like future opposing Civil War to come cavalry Generals John Buford and J.E.B. Stuart.  

The energetic man of letters and adventure Laurence Oliphant's article "The 'Foreign Connection' of the House of Bull." On British/French policies and relations. 

Scots author, critic, and teacher W.E. Aytoun's serial novel, Norman Sinclair (Part III). Here first printed, it's today a very rare item in book form (3 volumes).  

Edward G. Bulwer-Lytton's new extended verse narrative, "St. Stephen's." This is the third and last part of the work. Published by Blackwood's in volume form later in this same year, it's today almost impossible to find in either a first or a second book edition. 

British churchman and writer James White's opening the issue article "Lord Elgin's Mission to China and Japan."  

John Paget's essay "[Lord Horatio] Nelson and [Italian Admiral] Francesco Caracciolo." The later was destined to hang from the yardarm of his own ship under controversial circumstances that still don't seem to be finally settled even today.   

W. Lucas Collins' serial novel The Luck of Ladysmede, Part XIII, here first printed. The novel was later in this year published in two volumes by Blackwood's and is now a rarity in book form.
