Liber Investigatonis

in Latin, by Gerber, a.k.a. Abu Mussah Jabir ibn Hayyam al-Sofu

A very confusing primer on alchemy and Islamic mysticism, this work is nearly incomprehensible. A copy of this book was donated to the Orne Library as part of the first Pickman Bequest. (Johnson, Sam, and Sandy Antunes. "Miskatonic University: A Handbook to the Pride of Arkham." Chaosium, Oct. 2005.)
