The presence of moustachios and beard and the length of the hair on the head will assist in sex determination. The breasts if present will denote the sex, also the uterus, which withstands putrefaction and burning to a marked degree. Remains of clothing and ornaments will indicate the sex of the wearer. Lineæ albicantes on the abdomen, buttocks, and breasts indicate the female sex, and the probable occurrence of previous pregnancies. It must, however, be remembered that lineæ albicantes occur in males who have been stout or had the abdomen distended by disease. The Skeleton in Relation to Identification.--When a complete skeleton is submitted for examination, the chief points to elucidate are the age and sex. These will be noted further on. It may happen that a single bone, separate bones, or only a part of one is obtainable, when there may be considerable difficulty in expressing a definite opinion. The questions to be answered are: Are they human or belonging to the lower animals? When the bones are entire the answer is not very difficult to settle; but when parts of bones have to be dealt with, one has to be very careful in forming conclusions, and the fragments may have to be submitted, to a skilled anatomist. One may not be able to express an opinion about bones of the lower animals, other than to state they are not human. The services of a skilled Comparative Osteologist may be necessary to decide the nature of the animal. When fragments resembling bone have to be examined, the microscope will be necessary to determine their osseous structure. When several bones have to be examined it may be possible to build up part or the whole of a skeleton. Duplicate bones will indicate remains of more than one creature. All fragments and bones should be carefully described, measured, and photographed. By the character of the bones one may be able to determine the sex to which they belong and the approximate age. As a general rule the bones of the female are smaller, lighter, and less marked by muscular and other attachments. The thorax in the female is deeper than in the male, the sternum shorter and more convex, the ensiform cartilage thinner and ossified later in life. The cartilages of the ribs are larger and the ribs smaller than in the male. The ribs are more oblique and may show the results of long corset pressure. The body of the sternum is over twice the length of the manubrium in the male, less than this in the female.
