This led to their being- acknowledged as bony epiphyses, not apophyses of flie cranium; and, moreover, their situation or implantation over the coronal suture excluded them virtually from the cervine, bovine, and and antilopine category. The best sectional views that I know of, showing the constitution of these appendages and their relation to the skull itself, are those of Owen* in an ani- mal nine days old, and of Joly and Lavocatf .in the adult. Ficr. A mesial longitudinal section of the same horn, its soft basal substance, and portions of the frontal bone and brain : h, osseous substance of the horn; v, vascular channels penetrating the same ; fc, fibro-cartilaginous matrix; sk, the bony tables and diploe of the skull; dm, dura mater; br, brain. So far the opinion of the majority tallies with the fact of the giraffe's pair of rear horns being primarily epiphysial, ulti- mately coalescing with the bone beneath, so tliat trace of separate origin is with difficulty recognized. It rests with me to place on record additional demonstrative evidence of the early relation of these horns to the skull in an animal two months old. The accompanying woodcuts (figs. 1 & 2) are quite as suggestive and more explanatory than long de- * Trans. Zool. Soc. vol. iii. p. 2C5, pi. 2. fig. 4. t Op. cit. pi. 9. figs. 1 & 2. 13*.
