THE MICROSCOPE. 



wrinkles, or the fragments of the torn muscle will be 

 seen to be connected by the untorn membrane, as at 

 Fig. 296. This membrane is termed Myolemma. It is best 

 seen when a piece of muscle is subjected to the action of 



fluids, 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 

 s con traction of the muscle itself, 

 iiP. which is made up of a series 

 of bundles of highly elastic

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

 muscles pass directly into the bundles of the submucous 



connective tissue, which 

 serve as their tendons. Such 

 a transition is shown in fig. 

 298, No. 2; the tendon, the 

 lower part of which may be 

 seen passing insensibly into 

 the striped muscle, the glan- 

 dular sarcous elements of 

 the latter appearing, as it

as calcareous particles are 



deposited in bone), at first leaving the tissue about the 

 walls of the cavities of the endoplasts, and that in some 

 other directions, unaltered. These portions, which would 

 have represented the elastic element in ordinary connective 

 tissue, disappear in the centre of the muscular bundle, and 

 the endoplasts are immediately surrounded by muscle; 

 just as in many specimens of bone (see figs, of bone), the 

 lacunae have no distinguishable walls. On the other hand, 

 at the surface of tho bundle the representative of the 

 elastic element remains, and often becomes as much de-
