48 PATHOLOGY, 



2. Simple elementary forms of the nature of deposits, some- 



times of a mineral or inorganic character; e.g. (a.) amor- 

 phous granules ; (5.) crystalline structures in a granular 

 state. 



3. Simple but organised products capable of growth, — simple 



cells, compound corpuscles, fibres. 

 The various appearances and conditions which these simple 

 forms may assume in disease, as well as the functional states 

 with which they are frequently associated, lead to a further 

 enumeration and classification of morbid elementary products, 

 as well as of more complex disease processes, as below. 



MORBID ELEMENTARY PRODUCTS. 



I. Exudations more or less soft, semi-fiuid or fluid, and formed 



(a.) Germinal plastic and formed material, which has some- 

 times been called blastema, coagulable hjmph, false mem- 

 brane, ox fibrin, as seen adhering to free surfaces. 



(&.) Aqueous matter, as seen in the morbid state termed dropsy, 

 and oedema of parts. 



(c.) Gaseous exudations, as seen in the various forms of ;pneu- 

 matosis. 



II, Exudations more or less consolidated, and consisting of — 



(a.) Molecular or granular material, from -g-^xr^h of a line to 

 an immeasurably small size, and consisting cliiefly of the 

 simple forms of — 

 (1.) Fatty molecules of granules. 

 (2.) Forms of an organic kind capable of grow^th, and 

 invariably taking origin from a pre-existing 

 structure, 

 (3.) Deposits of an inorganic kind, generally calcar- 

 eous salts. 

 (4.) Pigment granules. 

 (6.) Coagulable compounds, resisting the action of most re- 

 agents, such as are seen in the elements of tubercle, 

 scrofula, oleo-albuminous formations. 

 (c.) Exudutions of a transitional nature, organised, capable of
