PAGES 



Chapter I. — Tlie natural history of parasitic fungi generally. — Reasons for undertaking the 

 study of the relation of fungi to disease — Purely botanical questions not discussed— The term 

 " fungus '■ adopted as most convenient in describing epi- and endophytic growths — The influence 

 of vitality in limiting the spread of fungi — The nutritive requirements of fungi— Possibility of 

 certain plants producing secretions especially adapted to the growth of certain fungi — Probability 

 of certain diseases producing secretions specially adapted to the growth of fungi — Flies and other 

 insects attacked by fungi — The inferences which would be natural were isolated growths of fungi 

 in the tissues demonstrated 337 — 340 



Chapter II. — The evidence recorded in favour of the fungal origin of the Madura foot-and- 

 hand disease. — The bibliography of the fungus-disease of India — Varieties of the disease dis- 

 tinguished by Dr. Carter — The dark and pale varieties compared — External appearances — 

 Appearances presented by the two varieties on section — Intimate nature of the abnormal products —

 developed in connection with the dark variety — The Rev. Mr. Berkeley's observations 

 regarding the pink mould 840 — 344

 disease of India. — Materials examined — Nature of the investigations — Reasons for beginning 

 the report with a description of observations on the pale variety of the disease — Description of 

 Specimen I — Greasy aspect of the preparation — Abundance of oily matter in the tissues — 

 Microscopic examination — Description of Specimen II — Cavities in the tissues : their nature and 

 contents — Condition of the bones— Microscopic examinations — Description of Specimen III — 

 Roe-like bodies and chalky crystalline masses — Condition of the bones — Various stages of 

 degeneration among the fatty tissues — Cavities and channels — Transitions between normal fat 

 and degenerate products — Results of microscopic examination — Description of Specimen IV —

 of the pale variety of the disease. — The degeneration may occur without the local presence of any 

 parasitic organisms — The disease essentially a degeneration of the fatty tissues — Nature of the 

 degenerative process — The proportion of gelatinoid and fatty products differs in various specimens

 certain morbid products — Myeline — DiflBculty of distinguishing vitalised from non-vitalised 

 products 353—356

 associated with the pale variety of the fungus-disease of India. — Red particles in a specimen — 

 Their microscopic structure — Behaviour with various re-agents — Effects of heat on them— Their 

 nature —Cause of their colour uncertain 356 — 360 



Chapter VI. — A description of specimens illustrative of the dark variety of the fungus-disease 

 of India. — Specimen I : section of a foot — Character of the cavities— Microscopical characters 

 of the ordinary tissues : muscles : fibrous tissues : bones — The dark material — Specimen II : a heel
