Nor was this custom confined to these races, for, in the words of Cicero: Antiquissimum sepulturae genus id fuisse videtur, quo apud Xenophontem Cyrus utitur; redditur enim terrae corpus, et ita locatum ac situm, quasi operimento matria obducitur.

CUSTOMS OF SELF-LACERATION, AND OF REMAINING WATCHING AMONG THE GRAVES.
The foregoing relations of the ceremonies practised at a native funeral exhibit some instances of the way in which they lacerate themselves in the exercise of certain superstitious rites, a custom very prevalent throughout all the yet known parts of Australia, and according with those described in the first book of Kings chapter 18 verse 28: And they cried aloud, and cut themselves after their manner with knives and lancets till the blood gushed out upon them.
And again, Jeremiah chapter 48 verse 37: For every head shall be bald, and every beard clipped; upon all the hands shall be cuttings, etc.
The natives of many parts of Australia when at a funeral cut off portions of their beards, and, singeing these, throw them upon the dead body; in some instances they cut off the beard of the corpse, and, burning it, rub themselves and the body with the singed portions of it.
"It may be also remarked," says Major Mitchell,* "that a superstitious custom prevailed among the Gentiles in mourning for the dead.

They cut off their hair, and threw it into the sepulchre with the bodies of their relations and friends, and sometimes laid it upon the face or breast of the dead as an offering to the infernal gods, whereby they thought to appease them, and make them kind to the deceased." See Maimonides de Idol 112 1, 2, 5.
(*Footnote.

Australian Expedition volume 1 page 254 note.) It is enjoined in Deuteronomy chapter 14 verse 1: Ye are the children of the Lord your God, ye shall not cut yourselves, nor make any baldness between your eyes for the dead.

Now the native females invariably cut themselves and scratch their faces in mourning for the dead; they also literally make a baldness between their eyes, this being always one of the places where they tear the skin with the finger nails.
The custom of remaining amongst the graves is found among the natives of nearly all known portions of Australia.
