Sint duo modioli ærei torno expoliti ſecundum interiorem eorum ſu-
perficiem ad embolos, quemadmodum bydrauleorum modioli A B C D
E F G H: & emboli ipſis congruentes ſint K L M N: ſimul vero modio-
li perforentur inter ſeſe per tubum X O D F: & ex partibus exterioribus
intra X O D F tubum habeant aſſaria appoſita P R, qualia in ſuperiori-
bus dicta ſunt, ita ut in partem modiolorum exteriorem aperiantur. Ha-
beant etiam modioli in fundis rotunda formina S T obturata axibus expo-
litis Y Φ Q Ψ, per quos fibulæ Ω Ω traducantur agglutinatæ, vel conjunctæ
modiolorum fundis, habenteſque colymatia ex partibus extremis, ut
ne axes exipſis amplius extrahantur: emboli vero habeant rectas regulas
compactas in medio ς quibus jungatur regula Z α, quæ ad medium qui-
dem moveatur circa fibulam {ευ} manentem, ad regulas vero ς moventur
