The cellular or areolar timue is so called because its 
meshes are easily distended and thus separated into cells 
"i- spaces which all open freely into one another, and are 
consequently easily blown up with air, or permeated by 
fluid. Such spaces, however, do not exist In the natural 
condition of the body, but the whole \areolar] tinmr forms 
one unbroken membrane composed of interlacing fibres.

court of the present day, extending not only to jurisdiction 
in cases of homicide and some others in which religion 
was concerned, anil to a general censorship of all affairs of 
state, but even to the supervision of education, and tn cer-
