The 4th Nerves will be seen on the outside of the pedunculi cerebri, between the cerebrum and the cerebellum (fig. G6, page 134). They are small and slender, and arise from a nucleus—dee]) origin—in the wall of the aqu^-eductus cerebri (Sylvius) behind that of the 3rd nerve (fig. 83, page 172), and beneath the colliculi posteriores. The 4th nerve is connected with the nucleus of the 6th nerve of the opposite side. After leaving their nuclei of origin, the 4th nerves pass backwards and outwards through the peduncles, then inwards to the superior medullary velum—s^qjerficial origin—where they decussate, so that the left nerve comes from the right nucleus, and vice versa (fig. 83, page 172). Hence it follows that the right 4th nerve supplies the left superior oblique. The 5th Nerves take their I mqjer/lcicd origin from
