This type of 18th c school atlas has been overlooked in the past but such items are now hard-to-find. According to Rodney Shirley, there was only one edition of this atlas but our copy is published by McDowall not Guthrie. OCLC only list two copies of this version. Maps are beautifully engraved by John Beugo (1759-1841).
