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 reach 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- 
demy of Natural Sciences of Philadelphia, vol. iv. p. 119.
