HISTOLOGY. 39 



i. WHITE FIBROUS TISSUE. 



Study the white fibrous tissue. 



1. Tease a piece of tendon of an animal and place 

 it on the slide. 



2. Stain with carmine. 



3. Observe the fibers running in a wavy line across 

 the field. This tissue is found in the following- places : 

 tendon, omentum, subcutaneous tissue and a few other 

 places. 



II. YELLOW ELASTIC TISSUE. 



Take the ligament of an ox's neck and prepare, stain, 

 mount and study. 



To differentiate yellow elastic tissue from white fi- 

 brous : take a scalpel and cut each one. The white 

 fibrous will remain unaltered, while the yellow will 

 curl up. Under the microscope the white will appear 

 to be in a straight or wavy line, while the yellow will 

 appear to be in branched processes. If you boil them 

 the white will yield gelatin, and the yellow yields elas- 

 tin. 



III. AREOLA TISSUE. 



It is composed of white, fibrous, yellow elastic and 

 adipose tissues, in varying amounts.
