From the Astrographic Catalogue we have: 
1894.30 I30?9 92"34 Donner. 
Therefore from the two positions the proper motion of A is: 
0T209 in 322?1 
If there is an error in Porter of the sign in declination, his 
position-angle would be 325?4.

From the three positions (1875-1911) we have for the appar¬ 
ent motion of A: 
o'! 185 in 39?4 
This is confirmed by the relative positions in A. G. and 
Lalande. As a further check I have connected a very faint star :

If the position by South

proper motion of <p Cancri

Further measures are needed for the proper motion of A, 
which is obviously very small. From meridian positions:
