The treatise contains numerous diagrams.
Begins (f. 15v, lines 2-6):
وتوفيقك تعتصم ياكريم الحمد لله الذي يوحد بإبداع الأحاد وتفرد بتأليف
صنوف الأعداد والصلوة على خير خلقه أشفع الشافعين يوم التناد وعلى
آله وأولاده الهادين سبيل النجاة والرشاد فإن أحوج خلق الله تعالى إلى غفران
جمشيد بن مسعود بن محمود الطبيب الكاشاني الملقب بغياث أحسن الله أحواله يقول لما مارست
الأعمال الحسابية والقوانين الهندسية حتى بلغت إلى حقائقها وبالغت في دقائقها
Ends (f. 122r, lines 3-5):
... وهذا آخر ما أردنا إيراده في هذا الكتاب و
الحمد لله تعالى على نعمائه والصلوة والسلام على خير محمد وآله الطاهرين
وأصحابه الهادين والمهتدين
