 minate in fibres of the same appearance, but provided 

 nuclei. It does not .appear to be certain how these fibres 

 end. Kolliker is not satisfied that the free extremit: 

 they appear to be, are the actual terminations ; but he as- 

 serts that in some rare instances they communicate with 

 each other. For the present this point must be considered 

 as unsettled.
