Mr. Rehatsek's Catalogue of the Mullā Fīrōz Library in Bombay shews that it is very rich in Persian works on astrology.

To the useful books on Astrology may be added the treatise of Julius Firmicus Maternus, a Latin writer of the 4th century A.D. A good and cheap edition of this work is in course of publication at Leipsic under the editorship of Charles Sittl. Firmicus describes the Dodecatemoria, p. 48, the Decani, p. 41, and has a chapter, p. 233, on empty and full degrees, the full being degrees where the Decani are found, and the empty where their influence does not operate.
