The first study of the unusual and dramatic physiology of the annual growth and shedding of the antlers of deer. "The amount of bony matter annually secreted to form antlers of the larger deer is enormous, antlers of the Red Deer having been obtained which weigh upwards of 74 lbs. while those of the extinct Irish deer must have probably scaled 100 lbs during life. 'In weight the Elk will scale from 900 to 1400 pounds and the antler may weigh as much as 60 pounds. The largest span of an Elk antler on record is in possession of the Duke of Westminister. It measures six feet one and one quarter inch' " (p. xv). Digital facsimile from the Internet Archive at this link.
