OF THE CELLULAR SYSTEM. 59 



Q. Are its diseases, distinct from those of the organs 

 into which it enters? 



*#. They are. Tumours form in this cellular texture 

 within the organ, or suppuration occurs in it; while, as 

 you will conspicuously see in tumour or abscess of the 

 liver, the secretion of bile will go on. The function of the 

 lungs going on, in the course of extensive disease in them, 

 is another illustration of this principle. 



Q. How is this cellular texture discovered in some or- 

 gans? 



*#. Maceration and ebullition will exhibit it. 



Q. What proves its existence in bones and cartilages? 



ft. The granulations essentially of a cellular nature, 

 which sprout from these in their diseases and injuries. 



Q. Is there any organ destitute of this internal cellular 

 texture? 



#. No it is an essential constituent of the nutritive 

 parenchyma of every organ. 



Cellular Texture of the Head. 



Q. Where do you find, on the head, this texture most 

 abundant? 



*ft. In the face; on the cranium there is little. 



Q. Is there much in the interior of the cranium ? 



A. Very little; a small quantity is found where the ves- 

 sels go in and out. 



Q. To what is the redness of the eye in phrenitis 

 ascribed? 



#. To the cellular communication through the orbit. 



Q. What occasions the weight and pain in the head in 

 coryza?
