Fig. 4.
That Side of the Left Vlna next the Radius.
A, An almost Semicircular Sinus of the Vlna, in which the Upper Head of the Radius, Fig. 5, 6. B B, is Receiv'd La∣terally:
B C, Its External Side next the Radius; B, its Lower End next the Carpus; C, its Superior (call'd Olecranum) towards the Os Humeri.
D, A Smooth Prominence at the Lower End of the Vlna, which is Receiv'd in a Sinus of the Radius, as above-noted, Fig. 3. D.
E, The Anterior Process of the Vlna, which Frames the Semicircular Sinus, Articulated with the Os Humeri, Fig. 1. K H. This Process is Receiv'd in a Sinus at the Inferior and Fore∣part of the Os Humeri, (Exprest Fig. 1. above K H) when the Cubit is Bended.
F, The Superior and Posterior Process of the Vlna in like Manner, Framing its Upper and Semicircular Sinus, which Process is Receiv'd in the Cavity (M, Fig. 2.) of the Inferior and Back-part of the Os Humeri, in an Extension of the Cubit.
G, Part of the Lesser Sharp Process of the Vlna, call'd Styloides.
