146 SPECIAL RESULTS IN THE URANOLOGICAL 



South East, but "darkened" a little in March 1606. 

 (Connaissance des temps pour 1846, p. 59) . The locality, 

 TT Scorpii, might easily have been confounded with the 

 foot of Ophiuchus, but the expressions South West and 

 South East, the reappearance, and the circumstance of 

 no mention being made of the final complete disappearance 

 of the star, leave the identity doubtful. 



/. Also from Ma-tuan-lin's notices: a star of con- 

 siderable magnitude, seen in the South West ; all more 

 circumstantial details are wanting. 



u. Discovered by the Carthusian Monk Anthelme, on 

 the 20th of June, 1670, in the head of Vulpes (R A. 

 294 27'; Decl. 26 47'), not far from Cygni. When 

 it first shone out it was not of the 1st but of the 3rd 

 magnitude. It disappeared at the end of three months, 

 but shewed itself on the 17th of March, 1671, being then 

 of the 4th magnitude. Dominique Cassini observed it 

 diligently in April 1671, and found its light very variable. 

 The new star was expected to have returned to its 

 original brightness at the end of about ten months, but 

 it was sought in vain in February 1672, and did not 

 appear until the 29th of March in that year, and then 

 only of the 6th magnitude, and has never been seen since. 

 (Jacques Cassini, Elemens d' Astronomic, p. 69-71.) 

 These phenomena induced Dominique Cassini to seek for 

 stars never before seen (by him !). He states that he 

 found 14 such stars, of the 4th, 5th, and 6th magnitudes 

 (8 in Cassiopeia, 2 in Eridanus, and 4 near the North 

 Pole) . From the absence of precisely assigned positions, 

 and as, moreover, like those found by Maraldi between 

 1694 and 1709, they are in other respects more than
