 which we are relieved from supposing the existence of 

 any mysterious intelligence in this organic rudiment, 

 by the workings of which the cilia are moved; and

 charges and discharges between the ciliate-cell and 

 any other bodies which may have a share in this action, 

 and in this way the vibration of the cilia may be con- 

 sidered as the intelligible sign of these charges and 

 discharges.
