Histogenesis of white matter of the spinal cord in goat was studied using 52 foetuses of various ages. By second month of gestation, the white matter became arranged in three funiculi. Thickness of white matter increased from fourth to fifth month and also from sacral region towards cervical region in the fifth month. The lateral funiculus exceeded all other funiculi in thickness. The fibre tracts like fasciculus gracilis, fasciculus cuneatus, dorsolateral fasciculus of Lissaeur, medial vestibulospinal tract and medial longitudinal fasciculus could be identified by middle of second month. Vascularity and cell density increased as the age advanced from middle of the second month onwards.
