The Oculo-Olfactoiy Bundle (PI. XXIX., Fig. 2) passes outwards and backwards to the thalamon. It was first described by Viallanes. 4. The Glosso-Olfactory Bundle descends to the infra-oeso- phageal gangHon. The Medullary Substance of the antennal gangHon has a very remarkable structure, exactly similar to that of the olfactory lobe of a Vertebrate. This structure was described by Dietl [175], and more recently by Bellonci [183], who terms it the olfactory ganglion. In optical sections it appears to be composed of a number of small lobes. These were formerly mistaken by Leydig for. Kic. 60.—A section of the Olfactory (antennal) Ganglion, seen with a fj oil immer- sion objective, showing the reticular glomeruli in which the fibres of the antennal nerve (a) terminate and from the centres of which those of the olfactory peduncle (/>) take their origin. giant cells. Each lobe appears in properly preserved sections as a glomerulus of fine fibres ; the centre of each is connected with a fasciculus of fibres from the peduncle of the ganglion ; and the periphery is continuous with a reticular network of fibres, which connects the glomerulus with the cells of the cortical substance, and with the fibres of the antennal nerve ; these are, many of them, given off from the glomeruli, a small fasciculus arising from each (Fig. 60). Both the glomeruli and the fibres of the antennal nerve are deeply stained by osmic acid, whenever this reagent is.
