I only saw one actual typo -- endeavor, misspelled "eneeavor." But some of the place names like Servia and Roumania and other oddities were considered proper at the time. I was confused by the comma after Magnetic in the list of inventions. Magnetic what? Did they mean magnetism? If so, that inventor was Faraday.
Oops, on re-reading I saw another typo — dodr instead of door in the word problem about kalsomining a room! I must have been distracted by kalsomining!
