73. Kitab al-'Izz wa al-Manafi' li-l-Mujahidin fi Sabil Allah bi-l-Madafi' Book of Honor and Utility for the Faithful Militating in the Way of God with War Engines. By Ibrahim al-Muwajjah f. Ahmed Ghanim f. Mahmud f. Zacharia, an Andalusian, from the city of Granada. The author remained there until the total expulsion of the Moors from that province, then with changed habit, after having completed not one sea voyage on ships called "silver galleons," he finally migrated to Tunis, where he applied himself especially to the art of ballistics, the rudiments of which he sets forth in fifty chapters. The book is written in folio in Mauritanian character and equipped with the necessary figures, noted more for curiosity than for novelty.

74. Hayat al-Hayawan Life of Animals by Kemaleddin Mohammed f. Issa Eddomairi (died 808). A most famous zoological dictionary from which Bochart in his "Hierozoicon" took many things.

The author followed alphabetical order and collected everything that pertains to the description of the nature and habits of animals from 560 books and 199 collections of poems. Several writers of epitomes reduced it to a compendium; Mohammed Shah Kazvinensis translated it into Persian and offered it to Sultan Bayezid I, in the largest folio size.

75. In this codex are: I. Durar al-Anwar fi Asrar al-Ahjar Pearls of Lights in the Secrets of Stones.
