Charles H. Spurgeon on Psalms 132:17

Make the horn to bud. In the beginning of the month of March the common stag, or red deer, is lurking in the sequestered spots of his forest home, harmless as his mate, and as timorous. Soon a pair of prominences make their appearance on his forehead, covered with a velvety skin. In a few days these little prominences have attained some length, and give the first indication of their true form. Grasp one of these in the hand and it will be found burning hot to the touch, for the blood runs fiercely through the velvety skin, depositing at every touch a minute portion of bony matter. More and more rapidly grow the horns, the carotid arteries enlarging in order to supply a sufficiency of nourishment, and in the short period of ten weeks the enormous mass of bony matter has been completed. Such a process is almost, if not entirely, without parallel in the history of the animal kingdom. —J. G. Wood, in "The Illustrated Natural History," 1861.
