350 Anomalies of Pigmentation among Natives of Nyasaland 
all these cases, however, all variations in colouration shade into one another, and 
it is evident pigment is present. 
Those cases which I have considered as spotlings show areas of various extent, 
always of a " pink " colour, with sharply defined margins, this being the test of 
a departure from the normal, which I consider includes the variations in colour 
above mentioned. 
The following is an analysis of nearly 400 adult males, between the ages of 
20 — 50 years, being prisoners and soldiers, and therefore they can be considered 
as taken at random from various tribes. 
379 Adult males examined with reference to colour of glans penis and prepuce. 
(A) 122 Circumcised: All have completely black glans penis except two 
(a and b). 
(a) Some spotty pinkish colour present at the seat of the operation 
cicatrix. (N.B. the circumcision was performed when subject was adult.) 
(b) Chambveka, the general colour of the glans is a dark brown, but there 
is a light brown spot on the dorsum near the meatus. 
(B) 259 Uncircumcised : 
(1) Inner surface of prepuce and the whole of the glans penis dark brown 
or black ............ 45. 
(2) There is a gradation of colour from the corona to the meatus and 
corresponding part of the inner surface of the prepuce from blue red, leaden or 
yellowish white to dark brown or black ...... 100. 
(3) Glans and inner surface of prepuce of a uniform colour, from a leaden 
white to a bacon-red .......... 75. 
(4) Glans and inner surface of prepuce of about the same colour as in 
a fair European, but at the free edge of the prepuce shading off into dark 
brown or black of the general skin colour ..... 20. 
(5) As in (4), except that the lips of the meatus were dark brown 3. 
In another case there was some deeper pigmentation about the frenum 
shading off into the surrounding colour; the skin colour was a dirty yellow 
brown, rather like that of a half-caste, with some freckling; hair black; irides 
dark brown ............ 1. 
(6) Spotlings .......... 15. 
From the above it will at once be seen that among the circumcised one may 
say no spotlings were found ; case (a) had some alteration in the neighbourhood 
of a scar and is of no import ; (b) had a condition which may be called leuco- 
derma, or may be a congenital condition, and be called albinotic, but no history 
was forthcoming.
