In a previous page we have described the manner of growth of the horn tubules, and noted the direction they took in the wall; also, we have noticed the existence between them of an intertubular horn or cement. Those who wish to give this subject further study will find an excellent series of articles by Fleming in the Veterinarian for 1871.

Under the microscope the longitudinal striation of the wall is found to be due to the direction taken by the horn 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 Reeks, H.
