Burnham: Measures of Proper Motion Stars 
As there has been no relative change in these stars in 80 
years, obviously the motions must be exactly the same. In this 
connection I have measured two small stars for the proper 
motion of AB.

The proper motion of the large star is wholly uncertain. 
Further measures of the small star will give this movement.

The principal star (Lalande 18708) is given some proper 
motion: 
A. G. Ber. o"n8 in 201 °o 
There is no change in AB. If these stars have any such 
movement, it will soon appear in the measures of the small star. 
The principal star is DM (20°) 2334 and not 2332 as given in 
Part I of the General Catalogue.

No material change since 1879. About 20' .y is h 604, but it is 
too large and diffused for accurate comparison with any of the 
stars in the field.

The principal star has a small proper motion. The six 
positions by 02 , Ho, Doo and (3 (1840-1912) give: 
o"o55 in 241?6 
As the two positions by 02 are each on a single night, 
further measures should be made for a final value of the proper 
motion. No proper motion found in the star catalogues re¬ 
ferred to.

One of these stars appears to have a small proper motion; 
the distance is slowly decreasing.
