Query: Kindle version is worthless

Kindle edition badly formatted - practically unusable. Can't figure out how to return and get my buck back, so I'll warn you not to spend yours.Oh, and even though the DTE of "Newly Revised" links here, this is actually the 1915 edition, which is in public domain and available free elsewhere. Maybe even properly formatted.
