III and IV, 49 per cent, than for I and II, 40 and 43 per cent,

Table 4. — Occurrence of lepra reactions. 





DOSE PRODUCING REACTIONS 



These reactions were produced, as is to be seen in Table 5 by 

 considerably smaller doses of the creosoted preparations than 

 of the plain.

It has been our experience that the lepra reactions produced 

 with the creosote solutions are not severe. For present pur- 

 poses the classification of reactions used in this colony in 1922 

 will be employed here; namely, Type 1, exacerbation of old 

 lesions with fever; Type 2, exacerbations of old lesions without 

 fever; Type 3, eruption of fresh lesions with fever; and Type 

 4, fresh lesions without fever. The data on the types occurring 

 are given in Table 6. For purposes of further comparison they 

 are tabulated in Table 7, on the basis of duration, as follows : 

 Very brief, less than one week; brief, one to two weeks; moder- 

 ately long, two to four weeks ; prolonged, more than four weeks.
