THE CELLULAR TISSUE. 



branous cavity and around glands and their granules, it 

 is more or less round. 



The quantity of this tissue varies according to its situation 

 in the body, and the period of life in which it is examined. 



In the cranium and spinal cavity, there is very little; on 

 the surface of the head and face and in the orbits, there is 

 more; about the trunk, both externally and internally, it 

 is abundant, and particularly in the mediastinum, within 

 the thorax, around the kidneys and rectum, and within 

 the abdomen and pelvis. In the extremities it is also 

 abundant, particularly in the axilla and groin. 



The quantity seems to be regulated as a general rule, ac- 

 cording to the motion of the part the greater the motion, 

 the more of this tissue is present; the kidneys, rectum and 

 some other parts, it is true, are exceptions. 



The quantity in infancy is greater than in the adult it is 

 also more abundant in women than in men and in the 

 lymphatic than in the bilious temperament. 



The consistency equally varies with the quantity but the 

 firmness is not found in a ratio with the quantity as in the 

 mediastinum and around the kidneys, where it exists in large 

 quantities, it is exceedingly fine, delicate, easily torn, and 

 having but a slight degree of consistence; whereas, in the 

 fascia lata of the thigh, the palmar and plantar fascia of 

 the hand and foot, it presents an extraordinary firmness 

 and degree of strength. 



The continuity of the cellular tissue can be traced through- 

 out the body. The foramina of the cranium are the means 

 of communication between the internal and external por- 

 tions of the head and face from the face it is continued 

 down the neck upon the external surface of the chest then 

 through the upper opening in the thorax, it enters this cavi- 

 ty, covering its different viscera; from this it descends along 

 the oesophagus and through the openings in the diaphragm, 

 into the abdomen and pelvis, from whence it is traced under 

 the crural arch and foramina of the pelvis, continuous with 

 that belonging to the extremities. 



It has been divided into the external and internal cellu-
