The anterior part, as is shown in figure 18, becomes (a) the olfactory bulb, (b) the olfactory peduncle or tract, (c) the trigonum olfactorium, lying between the lateral and mesial roots into which the tract divides, and (d) the area of Broca. The posterior part of the olfactory lobe (B in Fig. 17) becomes (a) the grey matter of the anterior perforated space, and (b) the gyrus subcallosus or peduncles of the co

Termination of the Olfactory Tract.—As is shown in figure 18, the mesial root terminates in the supra-callosal gyrus and fornix, while the lateral ends in the uncus of the hippocampal convolution.
