"When a bone is broken, blood trickles out between the incjured parts, and afterwards gives place to a sticky, watery fluid, which gradually becomes thicker, like a syrup or jelly. This is slowly replaced by a new bone structure and forms a kind of cement to gold together the broken ends." — Blaisedell, 1904

"This very extraordinary species from north-east Africa differs from all other rodents in the peculiar granulated plated which cover the temporal fossae, and from all the species of the section in the rudimentary condition of the clavicles as well as in the possession of an opposable hallux.

"Right pectoral arch of a bird. s, scapula; c, coracoid; gl, glenoid, the cavity for head of humerus; cl, clavicle; hc, hypecleidium. In situ, the right end of the figure should tilt up a little. The pectoral arch is that bony structure by which the wings are borne upon the axial skeleton. It is to the fore limb what the pelvic arch is to the hind limb; but is disconnected from the back-bone and united with the breastbone, whereas the reverse arrangement obtains in the pelvic, which is fused with the sacral region of the spine. Each pectoral arch of birds consists (chiefly) of three bones: the scapula and coracoid, forming the shoulder-girdle proper, or scapular arch; and the accessory clavicles, or right and left half of the clavicular arch." Elliot Coues, 1884
