 Page 5 has a report headed: "States Ofd The Union - The New States--Iowa and Wisconsin" with reports on both. Iowa formally joined the Union in December, 1846, and Wisconsin not until May, 1848.
Four pages are taken up with military reports, mostly on the: "War With Mexico". And the back page has: "The Mormon War" which includes: "...from Illinois left a force of about 1200 Anti-Mormons with some pieces of artillery, embodied near Nauvoo...The Nauvooites were still preparing for defence...The present sheriff is with the Anti-Mormons...that either 'a fight or a foot race' might yet be obviated...".
Sixteen pages, 8 3/4 by 12 inches, very nice condition.

As noted in Wikipedia, this title: "...(was) one of the most widely-circulated magazines in the United States...Devoted primarily to politics...considered an important source for the history of the period."
