DISEASE. 



The effects of disease, when they can be rendered obvious by 

 dissections, by the application of various instruments, such as 

 the microscope, and of chemical re-agents, are found to consist 

 for the most part of — 



1. Transformations in the elementary textures of the body 

 generally, and altered conditions of the fluids. 



2. The presence of new formations foreign to the normal 

 condition of an organ or system of organs. 



3. Change in the position or form of some of the organs or 

 parts of organs. 



4. Deposits in and around the elementary parts of tissues, 

 or changes of a degenerative or retrograde kind in them. (See 

 Aitken's Science and Practice of Medicine?) 



Anatomical investigations of morbid parts, conducted with 

 the aid of the microscope and other instruments of research, 

 show that the material of which their substance is made up is 

 of very various structure, sometimes combined in forms of one 

 kind throughout, and sometimes varied by the development 

 and combination of many elementary forms, more or less soHd, 

 soft, or fluid. 



An analysis of the morbid material, carried as far as 

 scientific means at present enable us, shows that the elemen- 

 tary conditions in which morbid products are found may be 

 described as follows : — 



1. Fluid matter and hyaline substance, more or less soft.
