97- Elementary muscular fibres of striped muscle, 

 newt ; showing transverse strise and masses of 

 bioplasm . . . . . . . . . . ..215 



98. Elementary fibres of striped muscle ; pig . . 215 



99. Large and small elementary muscular fibres, frog ; 



showing nimierous masses of bioplasm . . . . 215 



100. Elementary muscular fibre, water-beetle ; showing 



" discs" broken off within sarcolemma and masses 



of bioplasm in the centre of the muscular discs . . 215 



101. Extremely fine muscular fibres, showing transverse 



markings and bioplasm. Green tree frog . . 215 



102. Striped muscular fibres of calf at a very early 



period of development, showing large masses of 

 bioplasm in centre of each fibre, as in insect 

 muscle . ■ . . . . . . . . . . 215 



103. Very fine striped muscular fibres tapering into 



delicate fibres of connective tissue. Nose of the 

 mole 215 



104. Coiniexion between striped muscle and tendon. 



Chameleon . . . . . . . . . . . . 215 



105. Muscular fibres of pig, at difierent ages. The fibres 



to the left are from the pig at birth, and those to 

 the right from a pig three months old. In this 

 short time each elementai'y fibre has increased to 

 more than twelve times its bulk, and it will be 

 observed that the amount of bioplasm corre- 

 sponding to a given quantity of tissue is much 

 greater in the youngest muscle , . . . . , 100 



106. Muscular fibres of heart of very fat pig, showing 



adijiose tissue between them . . . . . . 130 



107. Striped muscular fibres in a state of fatty degene- 



ration . . . . . . . . . . . . 215 



108. Striped muscle. Hyla. Showing contractile ma- 



terial fractured within the tube of sarcolemma . . 130 



109. Elementary fibres of hyla, or green tree frog, in an 



extreme state of fatty degeneration from a muscle 

 which had long been inactive . . . . . . 220
