striated contents—even the distance of the strize-—the nuclei, 
are all exactly such as they are in the highest vertebrata. 
The nerves in insects have nucleated neurilemma and axis 
eylinder, but want the white narrow sheath, which is not con- 
stant in vertebrata. 
No one can doubt that muscle and nerve universally iden- 
tical in their construction have an equally universal identity 
in their manner of connection.
