The Hæmoglobin Index in Coolies

The returns presented hereunder are those taken from the examination of Indians and Chinese coolies newly arrived from their native coasts on a Rubber Estate in Johore. Absolute accuracy in the examination of stools could not be obtained owing to difficulties in the direction of discontent and distrust likely to be incurred by too drastic handling of newly arrived labourers. Two smears were taken from each person and were very carefully examined. The figures returned from these are high enough to afford a fair idea of what the actual results would have been had it been practicable to purge the coolies after suitable starvation. The records of only three forms of helminthiasis are given, although other forms were noted. The haemoglobin indices were estimated by Tallquist's hsemoglobinometer. I am indebted to Hospital Assistant P. Samy for his ready and tactful help, without which these records would not have been possible. I am also indebted to the Manager of the Estate who granted me permission to make such use of the coolies as was deemed advisable. The Indians were mixed gangs of Tamils.
