Plate I, Case I before treatment. 



II. Case I twelve days after treatment. The skin is everywhere perfectly 

 smooth. In the photograph of the posterior view it appears that 

 tumors still exist in the region of the popliteal spaces. This appearance 

 is due to the areas of pigmented skin. The granulomata here as else- 

 where have entirely disappeared and the skin is entirely smooth. 



III. Case II before treatment. 



IV. Case II nine days after treatment. The skin is everywhere smooth. 



Pigmented patches are visible on the lower extremities both anteriorly 

 and posteriorly. 

 V. Case III before treatment. 

 VI. Case III fourteen days after treatment. 

 VII. Case IV before treatment. 

 VIII. Case IV after treatment. 



Fig. 1. Nine days after treatment. The lesion on the chin is not 

 entirely healed. At the bends of the elbows the character 

 of the lesions has entirely changed. The formation of scar 

 tissue is evident. 

 Figs. 2 and 3. Three weeks after treatment. There are scabs over 

 the bend of the left elbow anteriorly, and poste- 

 riorly over the right elbow and popliteal spaces. 

 These have since disappeared and the skin has 

 become smooth.
