I. — Mycetoma : the Madura or Fungus-foot of India. By

 Westminster Ophthalmic Hospital, &c., &c. 



{Bead before the Royal Microscopical SociETy, June 7, 1871.) 



Plate XCII. 



A FEW years ago Dr. Vandyke Carter, of the Bombay army, made 

 us acquainted with a certain specific form of microscopic fungus, 

 which he alleges produces, among the native inhabitants of Madura, 

 and certain other districts in India, a peculiar disease, and since re- 

 cognized as the Fungusfoot of India (Mycetoma). A number of 

 specimens of the foot have been examined in this country, and it is 

 thought by some histologists and pathologists that most of them 

 exhibit the ravages of a fungus. It appears, however, that now 

 and then specimens have failed to satisfy those into whose hands 

 they have fallen of the fungoid character of the disease ; Dr. Carter 

 speaks of such specimens as a variety, and in place of a hving 

 fungus he says "numerous rounded bodies of a structureless or 

 finely granular appearance are seen, in which the fungus particles 

 were free from crystalline fringe, but still showing a cellular 

 structure, the true nature of which is degenerate fungi."* A 



DESCRIPTION or PLATE XCII. 



No. 1. — Altered fibrous tissue, mulberry-shaped fat-cells, &c., x 1.50. 

 „ 2. — Fat-vesicle and molecular matter, chiefly fat ; a few mother-cells filled 



with fat-granules, and granular contents of others distributed over field. 



X 150. 

 „ 3. — Crystalline matter (stearine ? &c.), fat-globules ; vegetable hairs, &c. x 150.

been removed, and the cancellous structure occupied by blacked masses 



of inorganic matter, x 50. 

 „ 6. — Papillae hypertrophied, and filled with granular matter; remains of a
