Examined for vit. A content by the SbCl3 reaction, nineteen livers from accident cases had a mean value of 297 blue units per gm.; 44 livers from pneumonia victims, 163. Average period of illness was 71/2 days. These lower levels probably existed before the disease began. The diet of these native mine labourers is standardised by Government regulation and has no apparent deficiency in vit. A. Orenstein treated pneumonia cases with vitamin A concentrate without indication of markedly increasing the vitamin reserve.
