嗅索異常の一例

Upon One Case of Abnormal Olfactory Tract

　嗅索が嗅球の後方で2本に分れ，再び嗅三角で相合していた一例に就て記載する。

　嗅腦の異常例に關する文献は少くはないが，其等は總て嗅腦缺如腦に關する報告ばかりであつて吾々は今日迄本例の如き異常例の記載に接したことはない。

The authors described upon an abnormal, accessory olfactory tract, found in the right cerebral hemisphere of a 62 years old woman.

The accessory olfactory tract branches off medianward from the normal tract at 4 m.m. behind the olfactory bulb, turns immediately backward and then runs, parallel to the nor-mal tract, till it reaches the olfactory trigone, into which it disappears.

On the outer surface it corresponded macro-scopically to intermediate olfactory stria, while it agreed histologically with Cajal's internal olfactory root.
