bird ; shomng great regularity of the arraugement 

 of the muscular bundles which have been divided 

 transversely. . . . . , . . . . . . 40 



83. TJnstriped muscle, arranged in bands ; intestine,

84. Tlxin 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 bauds of unstriped mus- 



cular fibres, with muuerous masses of bioplasm.

86. Thin membrane, showing unstriped mxiscular fibre 



cells. Many of the masses of bioplasm are trian- 

 gular, and some quadrangular, with muscular 

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

and termination of fibres of unstriped muscle in 

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

a bvmdle of fine nerve fibres is seen to the right 



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



92. Triangular miiscular 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
