Examination of an Albinotic Eije 
3. Tamil full-time foetus. Eyes received in alcohol, after formaline, from 
Dr H. Eraser, Kuala Lumpur, Federated Malay States, May 10th, 1910. Antero- 
posterior and equatorial diameters of the eyes are both equal to 18 mm. Iris 
stroma is lightly pigmented. Pigment is most marked at the anterior surface 
of the iris. The branched cells are not so dark as in the adult Tamil's eye. 
Choroid contains many pigmented cells, but these are neither so numerous or 
quite so dark as in the adult Tamil eye. Choroid is darker at yellow spot than 
elsewhere. 
4. Tamil foetal eyes received in spirit, after formaline, from Dr H. Eraser, 
Kuala Lumpur, Federated Malay States, March 10th, 1910. Eye measurements : 
right eye, antero-posterior diameter = 19"5 mm., equatorial diameter = 18 mm.; 
left eye in both diameters is equal to 18'5 mm. Iris contains much stroma 
pigment, which is most marked anteri(jrly and around blood vessels. No clump 
cells found. In front of the sphincter muscle the cells are branched. Ciliary 
body stroma is pigmented, but much less densely than in the adult. Choroid is 
pigmented most markedly at its outer parts and around blood vessels. 
6. Tamil full-time foetus. Both parents are Tamils. Eyes received in 10 ^ 
formaline, fi-om Dr H. Eraser, Kuala Lumpur, Federated Malay States, October 21st, 
191-5. Antero-posterior diameter of each eye = 18"1 mm., equatorial diameter of 
each eye = 17-7 mm. The chromatophores in the iris stroma are well defined and 
contain brown pigment granules. As usual the pigmentation is most marked in 
the anterior layers of the iris which are heavily pigmented (Fig. 3). Ciliary body 
has pigmented chromatophores. The choroid contains many pigmented cells, 
6. Malay-Tamil foetus (Father a Malay, Mother a Tamil), age 5 — 6 months. 
Eyes I'eceived in formaline from Dr George A. Finlayson, Singapore, July 13th, 
1910. Both antero-posterior and equatorial diameters measure 9 mm. The iris 
and the ciliary body have no pigment in the stroma. The choroid contains a few 
branched cells with pigment granules (Fig. 1). These cells are fewer than those 
in a seven-months' Chinese foetal eye, No. 10, and are principally situated at the 
posterior part of the eye. 
7. Dark-race infant (probably Malay, Chinese, or Tamil) thought to be still- 
born. Eyes received in formaline from the late Dr Robert D. Keith, Singapore, 
March 1st, 1915. Antero-posterior diameter of each eye = 18 mm. The iris 
chromatophores are pigmented with small brown granules that lie in the cell 
bodies and processes, some cells are more pigmented than others. The ciliary body 
has pigmented chromatophores as in the iris. The choroid is rather heavily pig- 
mented, especially at its outer part, and at the posterior pole of the eye. 
8 and 9. Two Chinese infants. The age of one is " about 2 weeks " ; of 
the other, not stated. Eyes received from Dr George A. Finlayson, Singapore,' 
March 14th, 1914. As the distribution and quantity of pigment in the iris and 
choroid is similar in these two cases, one description will serve for both. The iris 
stroma cells contain brown pigment granules. The amount of pigment in the
