ON THE ELEMENTARY PARTS OF THE HUMAN FABRIC. 



The whole fasciculus of fibrillae usually seems to end abruptly in a perfect 

 disk ; and the myolemma terminates there. The tendinous fibres are attached 

 to the whole surface of the disk; and probably become continuous with the

myolemma. Thus the whole muscle is penetrated by minute fasciculi of tendi- 

 nous fibres ; and these collect at its extremities into a Tendon. Sometimes the 

 muscular fibres are attached obliquely to the Hendon, which forms a broad 

 band that does not subdivide ; this is seen in the legs of Insects and Crusta- 

 cea, in which the muscular fibres have apenniform arrangement; being inserted 

 into the tendon, 'on either side, like the laminae of a feather into its stem. 



234. The Muscular Fibre of Organic Life is very different from the pre- 

 ceding. It consists of a series of tubes, which do not present transverse

strife, and in which the longitudinal strife are very faint ; these tubes are 

 usually much flattened, and cannot be shown to contain distinct fibrillae.
