colour; microscopically there was a diffuse brown pigmentation and granular 
pigment was fairly abundant. 
Another child showed the same changes under similar conditions. 
Old female inmate of the Central Prison of an age when grey hairs have 
usually appeared ; she was noticed, however, to have some brownish hairs, and 
others of a bright golden colour; the black and brown hairs were found to be 
tightly packed with black granular pigment — the golden hairs contained light 
yellow diffused pigment, but no granules. 
Kause. An old female lunatic, presented the same hair characteristics, macro- 
scopic and microscopic. 
Three men were noticed with a certain number of red hairs in the moustache, 
comparable to the hairs in the moustache of a " red haired " European. 
Yotam. Scalp hair black ; skin a lightish brown, is said to have darkened 
with age ; irides a dark hazel. Microscopically the red hairs contained a certain 
number of fine pigment granules, but also bright red diffuse pigment, black hairs 
absolute black, with granular pigment ; some of the hairs were partially red and 
partially black, each part showing the corresponding condition mentioned above. 
Pamandhe. Brown moustache hairs showed diffuse brown pigment and fairly 
plentiful black granules ; black hairs and some particoloured hairs as in case 
above.

V. Case of Leucoderma. 
I now describe a case which clinically is one of leucoderma. It is the only 
case showing leucodermic areas of any extent that I have met with, from which 
I think I may infer with reason that leucoderma is rare among these natives 
save in its minor manifestations. 
This case corresponds very well with a text-book description of the disease — a 
symmetrical and progressive condition associated with hyperpigmentation. Points 
of interest are that the patient is sure the hyperpigmentation has occurred on 
sites previously depigmented. The hairs on affected parts of the skin which are 
naturally hairy are black. Black hairs are also seen to occur on leucotic areas on 
non-hairy portions of the skin.
