Earthy matter . . . .20-25 „ Of all animals, the bones of birds (especially of the predaceous kind) contain the largest proportion of earthy matter. The bones of mammalia come next; then those of reptiles ; and last of all those of fishes. As in the birds of prey, so in the carnivora, the bones have a hard and compact structm-e. The tympanic bone of the whale is extremely hard ; but the skeleton most remarkable for hardness and weight is that of the manatee, which may be seen in the Osteological Series of the Eoyal College of Surgeons of England. When the late articulator to the College was taken to task for having charged the enormous sum of ^15 (mstead of about £5) for articulatmg the manatee, he pleaded, m justification, that the bones were so hard that it had taken him unusual labour to put them together, and had spoilt many of his tools. The truth of this assertion is at once clear to anyone who takes in his hand the weighty rib of a manatee. (See sections of ribs.
