fasciculi. This arrangement is readily distinguished, if several fas- 

 ciculi be drawn slightly from each other upon a plate of glass, and 

 the intervening areolar tissue be viewed beneath the microscope. 

 When the filaments Teach the rounded extremities of the fasciculi, 

 they become straight, and in this manner conjoin with the tendinous 

 filaments originating at the extremities of the muscular fibres. The 

 importance of this arrangement can be readily understood : from the 

 diagonally crossing course of the areolar filaments, comparatively 

 inelastic in themselves, the sheath is rendered elastic, thus per- 

 mitting the muscular fibres freely to move without their action being 

 interfered with ; while at the point of attachment of the fasciculi, 

 where any elasticity would be worse than useless, from the fact that 

 part of the muscular action would be lost in the mere extension of 

 an elastic substance, we find the filaments arrange themselves so as 

 to become part of the inextensible tendon. — Proceedings of the Aca-
