The following observations of some of these stars with a 

 5 \ -inch object-glass may be added as the result of the present 

 season: common epoch 1865 - 4 5. 



8 Herculis. Pale lemon yellow and lilac, by a perfectly 

 independent judgment. The comes exhibited the curious 

 phenomenon of oscillation (see Int. Oes. ii. 375) in a remarkable 

 degree. With a power of nearly 450, and an unsteadied 

 telescope, the vibrations were extraordinary. 



12 Canum. Pale yellow and fawn colour. 



44 Bootis. On a general view, both, pale yellow ; yet with 

 some not very definable difference : when more closely studied 

 B sometimes seemed inclining to bluish, but on the whole I 

 believe it was tawny. This was my first observation of the 

 pair with my present achromatic, and the result a perfectly 

 independent one. 



95 Herculis. Apple green and light orange : very clearly 

 marked. 



OCCULTATIONS. 



July 3rd. — ^8 Librae, 6 mag., 9h. 45m. to lOh. 48m. — 

 a Librae, 2| mag., 9h. 58m. to lOh. 52m. — 8th, p Sagittarii, 

 4 mag., 9h. 21m. to lOh. 11m. The double occultation on the 

 3rd will be a very interesting phenomenon, especially as one 

 of the stars is so large, and forms one of the members of an 

 optical pair, Number 10 of our Double Star List (Int. Obs., 

 i. 375).
