SYSTEMATIC SYNTHESIS OF TISSUES INTO ORGANS. 201 



that conjointly they are water is one of their characteristics, but not 

 one that either can exhibit alone. 



250. Illus. THE six ELEMENTS OF THE FIRST TWO GROUPS CON- 

 JOINTLY ARE nervous tissue, if combined in proper proportions and un- 

 der proper circumstances ; and that such is their property should be 

 their most distinguishing, as it is their most exalted, characteristic. 



251. ORGANS EXHIBIT only those characteristics that 

 can be discerned in the tissues of which they are con- 

 structed ; so that if the tissues are given, it is easy to de- 

 termine what an organ constructed from them can do ; 

 or, if what the organ can do is given, it is easy to say 

 of what tissues it is constructed. 



252. TISSUES ARE CONSTITUTED to pOSSCSS USeful 



properties. 



253. ORGANS ARE CONSTRUCTED to make a practical 

 use of the properties of Tissues. 



254. TISSUES VARY in quality, according to the pro- 

 portions of their constituents and the circumstances un- 

 der which they were constituted. 



255. THE PERFECTION WITH WHICH AN ORGAN WILL 

 FULFIL ITS USES will depend upon the character of the 

 Tissues of the Body, since organs can be no better nor 

 worse than the Tissues of which they are constituted. 



256. Remark. ONE KIND OF TISSUE THROUGHOUT THE BODY may 

 be good or bad, and the rest be the opposite ; or a Tissue in one organ 

 may be good or bad, and be the opposite in other organs, either for a 

 brief time or during a person's life, owing to accidental circumstances 

 in one case, and being inherent in the other. 



25 7. AN ORGAN MAY ITSELF BE COMPOSED OF PER- 

 FECT TISSUES AND NOT RECEIVE PROPER INFLUENCES 



from other organs, and thus its perfect action will be 

 interfered with. When this is the case, the organ is 

 said to be functionally deranged ; when its own tissues 

 are imperfect, it is said to be organically deranged. 



258. IN THE STUDY OF ORGANS THE PRIMARY OBJECT 



WILL BE to ascertain of what Tissues and how they are
