distances and positions of 380 double and triple stars , &c. 95 
v Canis Majoris continued. 
This star has undergone an obvious and considerable change

tion being called “ almost directly preceding” (Sep. 30), and 
“ very near directly preceding” (Dec. 31); expressions irre- 
concileable with a deviation of io° from the parallel.
