The above are personal names; when young the parents often change them, especially if the child be sickly, there being an idea that they will deceive the inimical spirits by following this practice. As the children grow up they are dignified further by a change of name: thus, “Si Mara” becomes “Ma Kari,” _i.e._ the father of Kari, being the name of a child of his father’s or mother’s younger brother or sister. If this younger brother or sister have no children, whose names are to spare, “Si Mara” must wait until he gets a child of his own, and then he takes his child’s name with “Ma” prefixed. The same custom holds good with women;--“Si Risi,” a personal name, being changed into “Nu Sangut,” _i.e._ the mother of Sangut. So, again, if the younger brother or sister (and this is a most comprehensive relationship) of a person’s father or mother have grandchildren, then the “Ma” and “Nu” are abandoned for “Bai” and “Muk,” the grandfather or grandmother: thus, “Ma Kari” might become “Bai Kinyum,” and “Nu Sangut” be metamorphosed into “Muk Weit.” _Marriage._--The prohibited degrees seem to be the same as adopted among ourselves: marriage with a deceased wife’s sister, it is said, is prohibited, as well as that between first cousins; and second cousins are only permitted after the exchange of a fine of a jar, the woman paying it to the relation of her lover, and he to her relations. Among the Sibuyaus, however, I have known an uncle marry his niece. _Heights._--MALE ADULTS: 4 ft. 10 in. (short); 5 ft. 1 in.; 5 ft. 3 in.; 5 ft. 4 in.; 5 ft. 5½ in.; 5 ft. 7 in.

They have little or no knowledge of medicine, though they sometimes collect pepper and onions with which to make physic, a kind of stomachic. The grated flesh of old cocoa-nut is occasionally applied to wounds and bruises, but there is no general knowledge even of the powers of rice poultices. Blue-stone they eagerly inquire for, and they have learnt its properties. Their most common physic is to get a friend to chew up a mass of sirih-leaves, areca and lime, until it is reduced to a thick red juice, which is then squirted from the mouth over the part affected. If this physic be thus administered by a regular doctor it will be more efficacious, but any one may do it. This mess is used indiscriminately for all diseases: stomach ache, sore eyes, ulcers, wounds, boils, rheumatism, as well as fever. When it is squirted on to the forehead it is supposed to be efficacious in relieving the accompanying headache. This is very much practised by the Malays, who thus render their sick, objects of disgust. I have often thought it necessary to insist upon the patient being washed carefully before administering European medicines.
