407 cultures were isolated and examined, and if these are divided up into the four groups of MacConkey, a comparison can than be made between the results given by these Chinese coolies with those obtained by MacConkey (1905) in England, Major Clemesha (1909) working with natives of Madras, and Castellani (1910) working with natives of Colombo.
The following table summaries these results:-

On the group classification, the results given by the Chinese coolies are very close indeed to those of MacConkey. The results obtained in Colombo are essentially different, and those of Madras occupy an intermediate position.
