This cannot always be discerned : but when the two ends 

 are drawn asunder it will be perceived to rise up in 

 wrinkles, or the fragments of Uie torn muscle will be 

 seen to be connected by the nntorn membrane, as at 

 fig. 326. This membrane is termed Myolemma. It is best 

 seen when a piece of muscle is - ubjected to the action of 



fluii.s, as diluted acetic or 

 citric acid, or the fluid alka- 

 lies which occasion it to swell 

 and become easy of separa- 

 tion It has no share in the 

 co i raction of the muscle itself, 

 win 'h is made up of a series 

 of 1 1 undies of highly elastic 

 fibres : portions of a separated 

 buij<lle are shown at fig. 327, 

 and the ultimate structure of 

 a fibre, under a magnifying po ver of 600 diameters, at 

 fig. 328, No. 1. 



Dr. Hyde Salter pointed out. that in the tongue the 

 muscles pass directly into the b indies of the submucous 



connective tissue, which 

 8ei ve as their tendons. Such 

 a t ransition is shown in fig. 

 32 3, No. 2 ; the tendon, the
