Plate I. 



Fig. 1. Showing callosities. 



Male, 38, Hindu, cultivator. Says the corns first began to appear two years ago. 

 He attributes the condition to injury by thorns, which, he says, was succeeded 

 by induration of the skin. Distinct callosities are visible in the photograph, 

 and it will be noticed that they do not all correspond to the areas most subject 

 to pressure, as in the case of ordinary corns. 



Fig. 2. Showing mycetoma with callosities. 



Another specimen is available, which shows this combination equally well, but is 

 not figured. Male, 20, Hindu, cultivator. He states that a year ago, while 

 working in the fields, a thorn entered his right foot, at the base of the second 

 and third toes. An abscess formed, and subsequently a hard, brawny swelling, 

 which later burst and discharged black granules. The photograph shows an 

 undoubted mycetoma, discharging black granules, in the situation indicated 

 above; and several callosities, resembling those of fig. 1, can be seen scattered 

 over the sole of the foot. 



Fig. 3. Shoioing mycetoma, with an adjacent patch, apparently mycetoma degen- 

 erating into a callosity. 



Male, 33, Hindu, corn and general dealer. He states that about a year ago a hard 

 swelling appeared about the middle of the outer border of the right foot, which 

 ultimately broke down and discharged black granules. Shortly before the 

 swelling was noticed he had struck his foot against a stone, and lie attributes 

 .the disease to that injury. In the photograph an undoubted mycetoma can be 

 seen, which discharged black granules. Internal to this is an indurated patch, 

 which was apparently mycetoma undergoing indurative changes, and which 

 probably (it is suggested), if left alone, would have developed into a callosity 

 like those seen most typically in fig. 1.

Fig. 4. Showing a diffuse induration of the sole of the foot, possibly a degenerative 



phase of mycetoma. 



Male, 20, Hindu, clerk. He states that about five years ago he noticed a small 

 corn (kapasi) at the middle of the sole of the right foot. This was followed by 

 others, and gradually the greater part of the sole became covered with a 

 horny growth. No discharge, granular or otherwise, was ever noticed. 



On excision, the growth was sent to the Imperial Research Institute, Kasauli, for 

 examination. The report received stated that the microscopic appearances were 

 those of a chronic granuloma, resembling mycetoma, but that no mycelial 

 elements could be discovered.
