Few details of the components of the dorsal longitudinal f asciculus their origin, their termination or their relationships within the path itself are known for any group of mammals. Certain components have been described by Bodian ('40) and others in the opossum, but our knowledge of the connections of the fasciculus is far from complete although the position of this mammal in the animal scale makes such Imowledge highly significant for comparative work. The accumulating evidence on the functions of the regions from which its known fibers take origin adds new interest to this' path. It has, for a long time, been regarded by most observers as a part of the hypothalamic discharge system and as concerned, among other functions, with the distribution of certain olfactory impulses, vital to many mammals but relatively unimportant to man. The following observations reveal relationships which suggest new functional values for the path and give added significance to its role in the physiology and behavior of niammals, including man.
