(72.) _Increase of the Number of the Horns._--As much wonder is sure to be excited by the fact, that bony prominences are subjected with as great certainty to the modelling hand of climate as softer parts, I give the following from a recent work, entitled, "_Gardens and Menagerie of the Zoological Society Delineated_," premising, however, that, in my opinion, temperature has a vast deal more to do with alterations in the horns than domestication or cultivation. "One of the most curious modifications produced by cultivation in the domesticated sheep consists in the augmentation of the number of its horns; two, three, or even four supplementary appendages of this description being occasionally produced in addition to the normal number. Under these circumstances the additional horns usually occupy the upper and fore part of the head, and are of a more slender shape, and take a more upright direction than the others, thus approaching in character to those of the goats, while the true horns retain more or less of the spiral curve that distinguishes those of the sheep. There exists a strong tendency to the propagation of this monstrosity, which is extremely frequent in the Asiatic races, but is also met with in a breed that is common in the north of Europe, and is said to have been originally derived from Iceland, and the Feroe Islands. In this case it is unconnected with any other anomaly, but in the flocks of the nomad hordes of Tartary, it is usually combined with an enlargement of the tail, and adjacent parts, by the deposition of fat, frequently to an enormous extent."
