It is evident that the distance of the weight (or power) from the fulcrum (F) is influenced by the length and slope of the pastern; it being greatest when the pastern is long and oblique, and least when that part is short and upright. I may point out that increased growth of hoof, either at the toe or heel, will. Fig. 39.—1ST Order. Fig. 40.—2ND Order. Fig. 41.—3RD Order. Levers of the Hock. affect the slope in question, and that the thickness of horn at the toe will, of course, influence the length from the fetlock to the toe. As a practical point I may remark that the toe (except in the treatment of some forms of disease) should always be kept low, and that shoes should be no thicker at the toes than what would be sufficient to enable them to stand " ; I have alluded to this subject furtlier in my Veterinary Notes for Horse Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Hayes, M.
