In this man we see a case to be placed in Class IV, a group characterised by 
light brown skin colour (not red), in adult life, with nearly always a history of 
darkening with age ; the irides are hazel, the hair, though it is a dark brown 
colour, contains no pigment granules. 
Case C 9. Nderemani of Namahuere Village, Fort Maguire. 
This man, aged 25 years, was seen in Zomba in 1911 when returning from 
work on the South African mines. 
Skin a rich "warm" brown colour; hair a rich red brown hue; axillary hair a 
dark brown ; there are a few golden coloured hairs on the body and limbs. Irides, 
dark hazel ; no nystagmus ; vision good. There is a small umbilical hernia 
present. He says he has darkened with age and more rapidly since going to the 
mines than before. 
This is a typical case of Xanthism, Class III. The hair, on microscopical 
examination, was found to contain few pigment granules, but a considerable 
amount of diffused pigment. 
Case C 10. Mateuta of Chiri, W. Nyasa. 
Father of average colour. Mother states that she used to be " white " when a 
child ; at the present time her skin tint is a light brown ; irides hazel ; hair black. 
Mateuta, a child aged 2 years ; skin colour a very light brown, face of lighter 
tint than body ; irides greenish hazel, no nystagmus ; hair light brown yellow 
with red glint in it ; eyelashes and brows of a lighter shade ; no hair on body. 
As an infant, is said to have been nearly " white." Vision apparently good. 
Mother and child constitute, I think, a short series, showing a progressive pig- 
mentation, of value to the general subject. 
Their histories show them to have possessed at birth a white, or almost white 
skin, which has become pigmented with age ; the child's skin has not yet reached 
the degree of pigmentation of the mother's. The child's hair is a light brownish 
yellow, which is becoming darker; whether it will actually become black remains 
to be seen, but I expect it will. The same is true of the irides. The mother's 
are hazel, the child's are greenish hazel, strongly suggesting that increase of 
pigmentation is in process of taking place. 
Case Oil. The child of Annie and Annausu of Nkumbira, Nkata Bay. 
Pedigree, Plate XXI, Fig. 12. 
All relatives dark; no other cases of albinism in family. The child (II 12) aged 
8 years, is stated when born to have been almost white and to have darkened 
since ; the same is said to be true of the hair. The face is a very light sallow 
earthy colour with dark freckles ; skin of body a warmer tint of brown. Hair of 
scalp dark brown. A few fine downy hairs are seen on the body and limbs. Irides 
hazel ; no nystagmus ; vision good.
