observations establish the point in question, viz. that a very 

 considerable diminution of distance really accompanied the 

 great increase of angular velocity, and that as the velocity has 

 since diminished, the distance has actually undergone a 

 corresponding augmentation. It is much to be regretted 

 that the opportunity of observing this interesting object in 

 perihelio has been lost. ( H. )
