82. Transverse section of muscular tissue of gizzard of 



bird ; showing great regularity of the arrangement 

 of the muscular bundles which have been divided 

 transversely. . - . . . . . . . . 40 



83. Unstriped muscle, arranged in bands ; intestine, 



frog 130 



84. Thin membrane ; showing bands of unstriped mus- 



cular fibres with vessels (injected blue). Frog. 

 Numerous masses of bioplasm in connexion with 

 all the tissues . . . . . . . . 20 



85. Thin membrane, showing bands of unstriped mus- 



cular fibres, with numerous masses of bioplasm. 

 Frog.. 130 



86. Thin membrane, showing unstriped muscular fibre 



cells. Many of the masses of bioplasm are trian- 

 gular, and some quadrangular, with muscular 

 fibre radiating from each angle. Frog . . . . 215 



87. Unstriped muscular fibre cells, showing bioplasm 



and termination of fibres of unstriped muscle in 

 connective tissue . . . . . . . . . . 215 



88. Unstriped muscular fibre cells, with vessels. White 



mouse . . . . . . . . . . . . 215 



89. Artery, showing unstriped muscular fibre cells en- 



circling it, and nerve fibres. Chameleon . . 40 



90. Small arteries ; pia mater brain, showing unstriped 



muscular fibre cells encircling them . . . . 130 



91. Arteries and vein, with numerous small branches ; 



a bundle of fine nerve fibres is seen to the right 



of the artery . . . . . . . . 40 



92. Triangular muscular fibre cells from the aorta of 



the human subject. These much resemble some 

 of the muscular fibre cells of the frog's bladder 

 described in prep. 86 . . 215 



93. Small artery, frog; showing muscular fibre cells 



encircling it, with numerous nerve fibres rami- 

 fying outside the muscular coat . . . . . . 215 



94. Small arteries with muscular fibre cells ; membrane 



of brain at an early period of development . . 215 



95. Artery torn lengthwise, showing individual mus- 



cular fibre cells, with their masses of bioplasm . . 215 



96. Elementary fibres of striped muscle with vessels, 



newt. Observe the masses of bioplasm . . 40
