Thirty-one patients were selected from among the best-nour- 

 ished inmates of the wards. Under the system followed in 

 this colony chiefly advanced cases that require hospital care on 

 account of deformities, or treatment of complications and se- 

 quelae, are assigned to the General Hospital. Among those 

 chosen for the experiment eight showed signs of pulmonary 

 tuberculosis ; only one of these was given the treatment for the 

 full period of the experiment. 



Thirty of the cases were lepers ; one, found to have ulcerative 

 tertiary yaws, received injections for two months before she was 

 sent home. Though eliminated from consideration as a leper, 

 this case served to some effect as a control. 



In most of the cases the disease was advanced. Efforts were 

 made to represent all types and degrees of ulcerations, contrac- 

 tures, deformities, and eye complications. None of the cases 

 could be classified as pure cutaneous. Seven were neural, and 

 twenty-three mixed. The ages are given in Table 1 ; the major- 

 ity were above 30 years of age, and 36 per cent were in the 

 fourth decade. The duration of the disease is shown in Table 

 2. The greatest duration was twenty-two years, the shortest 

 two, and the average eleven.
