The amnatomy of tlae distribution of the N. olfactorius in the fowl is described andillustrated in detail on the basis of studies on 8 complete cases of macroscopical dis-section and 9 cases of microscopical observation. Ilistological materials were fixed inBouins fluid, 100% alcohol, or 50% pyridin. They were treated by the Bielschowskyor Cajal silver impregnation methods, and made to paraffiun sections 2Os30 p thickness.The nomenclatures of the N. olfactorius given in literature on the bird are discussedat full length. The following findings warrant emphasis.The N. olfactorius arises with about 30 fine rootlets at the rostral end of the Bulbusolfactorius, and runs into the ocular cavity passing through the Foramen (nervi) olfac-torii. It then runs forward along the dorsal edge of the orbital septum. At the levelof the caudal pole of the nasal bone, the N. olfactorius divides into two branches (Figs. 1,2), which are named he Rami interni and Rami externi (Figs. 2, 4). The formerruns ventrolaterally into the posterior turbinate bone (Figs. 4, 5, 6) and finally dividesinto filaments, which are distributed over the dorsal mucosal surface of the turbinateprocess.The latter runs forward into the dorsal wall of the posterior turbinate bone (Figs. 4,6), and is distributed oxzer the dorsal mucous membrane of the turbinate bone, dividinginto filaments.Neither the N. terminalis nor the nasoxromeral organ, or Jacobsons organ, is foundin the adult fowl. This result is the same as already mentioned in literature.
