By the aid of the mi(^roscope, the peculiar character of the bone is clearly shown, though the 1)one of an Ostrich or Cassowary is very different from the same bone in a fowl or a pigeon. The wings are almost wanting externally, their bones, although retaining the same number and form as in ordinary birds, being very small, as if sud- denly checked in their growth. Tlie huge mng muscles which give such prominence to the breast of flying birds, are therefore not reqnired, and the breast-bone is consequently devoid of the projecting keel, and is quite smooth and 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 Wood, J.
