1. A further improvement in the modified McLeod's medium (Gaze, 1933) has resulted from the substitution of saccharose for glucose with the addition of Andrade's indicator.

2. Of the total positive swabs, the saccharose-containing medium detected about 22 per cent which were negative on Loeffler's medium, whereas it failed to detect only 0·36 per cent.

3. On this medium colonies typical of the gravis, intermediate and mitis types are formed and can be easily differentiated with the aid of a hand lens. It is also invaluable for the isolation of pure cultures.
