HAIR 45 lead, bismuth, or silver, or rendered lighter by using chlorine, hydrogen peroxide, dilute nitric acid or nitrohydrochloric acid. In India, seme old people colour their hair red or black for the purpose of concealing their age and of looking young. It must be remembered that a change may occur in the colour of the hair of men working in certain trades. For instance, the hair of ebony-turners and copper-smelters may acquire a greenish hue, while that of indigo workers becomes blue and cobalt miners exhibit a bluish tint. A Mohamedan midwife, named Sharifan, disappeared suddenly from her house in Ganda Nalla, Delhi. On suspicion the police raided the house of one Shahab-ud-Din in Hamilton Road after several weeks, and unearthed the dead body of a woman after getting a large portion of the house dug. The body was in an advanced state of de- composition, but it was identified as that of the missing midwife from the dyed hair which was intact. A rope was found round the neck, which led to the suspicion that death was in all probability brought about by strangulation. The owner of the house was arrested, against whom, a case under section 302, I.P.C., had been registered.43 Detection of Colour.—The colouring of the hair can be detected by examining the scalp, which will, as a rule, be found dyed, and the colour of the hair will not be uniform, the roots being different in tint from the rest. Such hair is rough, brittle and lustreless. The colouring can also be ascer- tained by comparing the hair of the head with that of other parts of the body, such as pubes and armpits, which is usually not dyed, as it is not likely to be open to the gaze of the public. In doubtful cases the hair should be shaved or cropped closely and the colour of the growth of the new hair should be observed, while the person is kept in custody for a few days. Chemical Examination.—To find out the mineral used for dyeing, some hair should be steeped or boiled in dilute hydrochloric or nitric acid to dissolve out the metal and the appropriate tests should then be applied to the solution thus obtained. 6. ANTHROPOMETRY This is a system chiefly used for the identification of habitual criminals. There are two methods by which this is carried out. One is called the Bertillon System or Bertillo>nage and the other is called the Galton System. Bertillon System.—This system is called Bertillonage from the name of its inventor, M. Alphonse Bertillon. It is applicable only to the adult, since it is based on the principle that after twenty-one years of age no change occurs in the dimensions of the skeleton during the rest of the life and that the ratio in the size of the different parts to one another varies considerably in different individuals. It consists in taking the measurements of certain parts of the body and then classifying the individual. The measurements that are usually taken are the height of the person while standing, the length of the head, the width of the head, the length of the right ear, the width of the right ear, the span of the outstretched arms, the height of the trunk while sitting, the length of the left foot, the length of the left middle finger, the length of the left little finger and the length of the left forearm and hand (cubit). These measure- ments are entered upon cards which are kept in a specially arranged cabinet, so that they can be easily picked out when required. The colour of the iris and certain peculiarities, such as scars, etc. are noted on these cards, and photographs of the full face and the right profile are also kept along with them. This system is useful for the identification of criminals, but it neces- sitates the employment of special instruments and a large number of men, so that there is always a possibility of errors creeping into the records of the actual measurements.- 45.
