cate lines, which are called sarcostyles and can be 

 demonstrated by taking a piece of the tissue and disso- 

 ciating the same. This will separate the lines into in- 

 dividual fibrils. Each fibril is called a sarcostyle. The 

 space between the sarcous elements is filled with sub- 

 stance, which is called sarcoplasm, and is analogous 

 to the protoplasm in other cells. This protoplasm is 

 endowed with the special power of motion, or con- 

 tractility. If we use a very H. P. we will be able
