 stars, aud then showed how he proposed that his instrument 

 should in a certain measure supersede these. He exhibited 

 portions of the apparatus which he had used, as well as 

 numerous specimens of the work done by it. He pointed 

 out how this method would be especially serviceable in

 present in the field of observation. This might be done by 

 superimposing the observations of successive nights, and 

 noticing if any one of the stars had changed its relative 

 position.
